Define the product category before you sample
This article covers a fleece camp blanket with an integrated self-stow pocket, usually sold into outdoor accessories, event merchandise, auto, club store and general retail channels. It is not the right platform for wet-ground insulation, thermal camping sleep systems or ultralight trekking. If the brief requires a waterproof ground side, compare backed mat constructions such as 190gsm brushed polyester picnic blankets with fold-out PE pocket wet-isolation planning or 210D nylon ripstop picnic blankets with 60gsm polyester padding quilting.
For this category, the usual base cloth is 100% polyester circular-knit fleece in a finished-fabric range of about 210-230gsm, with one face brushed and sheared and the reverse lightly brushed or plain. Circular knit remains the common sourcing choice because it is easier to invert into a pocket than a stiffer warp-knit construction and is usually more available in commercial colours. Warp-knit brushed constructions can reduce stretch distortion and improve packed-shape repeatability, but they are less common in this exact price band and may raise MOQ.
Write the product brief around the variables that drive claims and chargebacks: finished fabric GSM, open blanket size, approved fold map, stuffed dimensions, pocket opening width, pocket reinforcement, decoration type and location, carton count and inspection timing. If those points stay vague, the mill and sewing line will optimise for ease of assembly, not repeatable self-stow performance. Buyers comparing alternative carry formats may also review specifying 180gsm microfleece travel blankets with nylon carry pouches or 220gsm polyester polar fleece blankets with self-fabric carry loops before locking an integrated pocket program.
What 220gsm should mean on the PO
State clearly whether 220gsm refers to finished fabric weight before cutting or average finished blanket weight. In most mills, '220gsm fleece' refers to finished fabric weight after dyeing, brushing, shearing and anti-pill finishing, measured on the body fabric before cutting. It should not be used as shorthand for the net blanket weight because hemming loss, pocket panel addition, label package, moisture regain and size tolerance all move the final piece weight.
For sourcing control, specify both metrics. A practical buyer wording is: body fabric finished weight 220gsm ±5% tested on bulk fabric; finished blanket average net weight by size to be recorded for PPS and final inspection with an information tolerance, not as the primary acceptance criterion. That distinction avoids a common dispute where a blanket passes fabric GSM but misses packed cube because brushing raised loft, or passes finished piece weight because the pocket panel adds mass while the body cloth is light.
Brushing, shearing and anti-pill finishing shift both GSM and packed volume. A deeper brush or higher residual loft may keep the nominal GSM unchanged while increasing stuffed thickness and reducing size recovery after compression. Buyers should therefore freeze not only GSM, but also finished pile appearance and packed-size result at PPS. If anti-pill performance is a priority, align expectations with the test method and end use; for adjacent guidance see anti-pilling test requirements for 240gsm polar fleece blankets.
As a field-based rule rather than a lab standard, 220gsm fleece with a self-fabric pocket usually packs more consistently when the finished cloth is on the denser, shorter-loft side of the commercial range. In practical terms, that means less lofty hand, lower mouth bulge and more stable stuffed edges. If the consumer promise prioritises extra plushness, expect a larger cube or a wider tolerance.
Pocket construction drives most failures
The integrated pocket assembly is the highest-risk zone, especially both ends of the opening and the two lower corners. Users rarely load the pocket in a clean static way. They push a folded blanket into the pocket, usually leading with one corner and twisting slightly. That creates concentrated burst, slippage and peel-like loads at the seam line rather than a simple carry load. A plain perimeter seam without reinforcement is the most common failure mode on cost-down samples.
For this product, a flat pocket is usually the correct baseline. It gives lower sewing variation, lower material complexity and a more stable packed silhouette than a gusset on most 220gsm fleece programs. Gusseted pockets can rescue an undersized concept, but they add seam length, create extra fold memory and make inversion less repeatable. If the approved cube cannot be met with a flat pocket sized to the fold block, the first question should be whether the fabric loft, decoration bulk or fold map is wrong before adding a gusset.
Replace subjective terms with measurable controls. Instead of 'medium density' or 'moderate stretch', ask the supplier to record the fleece orientation used for the pocket opening, the finished opening width, the seam allowance, the SPI, the bartack dimensions and the approved stuffed size. Those are observable controls at line level. Handfeel language can stay on the commercial brief, but pass-fail should sit on measurable construction points.
Pocket opening orientation matters. On knit fleece, running the mouth along the higher-stretch direction makes stuffing easier but increases mouth flare, seam grin and post-cycle distortion. Running it along the lower-stretch direction improves packed-edge stability but raises insertion force. There is no universal right answer; the choice should be fixed at proto stage and documented on the fold map and pattern. That recommendation is based on common factory practice and field failure review, not on a standalone lab standard.
Decision tree: self-fabric pocket, woven facing or woven pocket body
Use self-fabric pocket panel with self-fabric opening when the program is price-led, decoration is light, stuffed cube is not a headline claim and expected stuffing frequency is low to moderate. Typical cases are promo, event and basic club-store blankets. The trade-off is higher mouth growth and less packed-shape consistency after repeated use.
Use a self-fabric pocket panel with a light woven facing at the opening when the buyer needs a repeatable packed cube, cleaner edge geometry and better resistance to mouth flare without moving to a separate pouch. A 75D-190T polyester facing or similar light woven construction is a common commercial choice because it adds stability without excessive bulk. This is often the best balance for mainstream retail 220gsm fleece.
Use a full woven pocket body only when cube target is tight, decoration on the pocket is more structured, or the product is expected to be stuffed repeatedly in the field. It reduces local bulk and stretch but can introduce handfeel mismatch, shade mismatch and puckering risk at the join line. It also becomes less forgiving if the fold block drifts from the approved map.
If decoration includes dense embroidery, rubber patch or multi-layer appliqué on the pocket zone, move away from a self-fabric mouth unless the cube target is relaxed. If the blanket will be compressed and re-stuffed frequently, upgrade the opening construction before simply increasing SPI. More stitches do not solve seam slippage in a stretchy fleece if the opening architecture is wrong.
Pattern engineering: pocket size, placement and opening finish
Pocket panel dimensions should be set from the approved fold block, not from a generic percentage of blanket size. On a 220gsm fleece blanket, start by fixing the folded pre-stuff block, then add only the allowance needed for insertion, seam turn and production variation. In practice, the finished pocket width and depth should be about 10-18% larger than the approved folded block dimensions for a self-fabric pocket, and about 8-15% larger for a pocket with a stable woven facing. The exact number depends on loft, decoration and mouth orientation.
Recommended starting placement is one corner of the blanket, on the less prominent branding side unless the pocket itself is a branding feature. Keep the pocket close enough to the edge to minimise extra fold bulk, but far enough from the hem turn to avoid sewing congestion. A common layout is pocket perimeter set inboard around 20-35mm from the two blanket edges, depending on hem depth and machine access. Corner placement is usually more stable than a central hem location because the fold path can terminate naturally into the pocket.
For blanket sizes used most often in this category, workable proto baselines are as follows, all as finished dimensions after hemming: 127x152cm blanket, folded block target about 24x26x9cm, pocket panel about 28-30cm wide x 30-32cm deep, finished opening width about 24-26cm. 130x170cm blanket, folded block target about 26x28x10cm, pocket panel about 30-32cm wide x 32-34cm deep, opening width about 26-28cm. 150x180cm blanket, folded block target about 28x30x11cm, pocket panel about 32-35cm wide x 34-37cm deep, opening width about 28-31cm. 150x200cm blanket, folded block target about 30x32x12cm, pocket panel about 34-37cm wide x 36-39cm deep, opening width about 30-33cm. These are starting points for proto, not universal pass points.
Pocket opening finish should also be specified. For most 220gsm fleece programs, a hemmed opening is acceptable on self-fabric pockets if the mouth is not carrying dense decoration and the stuffed cube tolerance is not tight. A faced opening is usually the best technical default for mainstream retail because it stabilises the mouth with limited bulk. Bound openings are more durable but add noticeable local thickness and can print through in the packed cube; they are usually better suited to tougher outdoor formats than soft retail fleece throws.
Specify reinforcement geometry, not just 'reinforce opening'. A practical baseline is bartacks at both opening ends, approximately 8-12mm long, set perpendicular or slightly angled to the opening edge, with the tack catching hem/facing layers fully. For lower pocket corners, use either a small triangular reinforcement shape in the seam path or an additional short return bartack near the corner if the sewing line can place it consistently. A rounded lower pocket corner radius of roughly 8-12mm often distributes stuffing stress better than a sharp square corner on fleece.
Acceptance criteria for fold map, seams and stuffed size
Buyers should define the core sourcing claims as measurable acceptance points. A practical spec set includes: open size with tolerance, approved fold map, folded pre-stuff dimensions, pocket opening width, stuffed dimensions, seam allowance, SPI range, bartack positions and carton pack assumption. Without those, 'packs into pocket' is not inspectable in a repeatable way.
For a mainstream 130x170cm 220gsm fleece blanket with integrated pocket, a commercially workable acceptance example is: finished blanket size 130x170cm ±3%; body fabric 220gsm ±5%; pocket opening finished width 27cm ±1cm; folded pre-stuff block 26x28x10cm ±1cm each axis when folded to approved map; stuffed size 28x30x11cm ±1.5cm each axis averaged across the approval sample set; pocket seam allowance 10-12mm; sewing 8-10 SPI on perimeter seams and 10-12 SPI on woven facing joins if used; bartacks at both mouth ends plus reinforcement at lower corners as approved on PPS.
Stuffed-size approval should be based on an average and an individual-piece limit. A good buyer control is to average 5 samples from PPS and 8 samples at final inspection, with no individual piece exceeding the target stuffed dimensions by more than 2cm on any axis and no average exceeding by more than 1cm. This matters because operator folding variation can move one piece a lot while the line average still looks acceptable.
If a compact retail cube is a marketing claim, add a visual acceptance point: edges reasonably square, no mouth flare beyond 15mm at the centre of the opening, no exposed raw fold corners after stuffing, and no diagonal twist that prevents flat front presentation. Those are field-observable defect signatures that inspectors can actually recognise.
Seam strength is not seam slippage: specify both
Many buyer briefs ask for 'seam strength' and assume that covers the pocket risk. It does not. Seam strength and seam slippage are different failure modes and should be tested separately where the pocket is critical.
For seam strength on the pocket perimeter and opening assembly, use a recognised seam-strength method such as ISO 13935-2 or ASTM D1683, depending on market preference and lab capability. The buyer should define where to sample and what direction to test. For fleece camp blankets, test at least the pocket lower corner seam and the opening-end seam zone, because these are the highest-stress locations in use. A practical commercial threshold often used for this category is not less than about 180N to 250N before seam failure on critical pocket seams, with the exact target adjusted for construction and market tier. State the threshold on the approved construction, not as a generic number divorced from fabric and seam type.
For seam slippage, use ASTM D434 or the closest locally available equivalent if the market accepts it. This test is especially relevant on fleece because the structure can deform and expose seam grin before thread break. Buyers should specify direction and load. A workable approach is to test the pocket opening area and body seams separately: body side seam or hem-adjacent seam at a specified load, often around 60N to 90N, and pocket opening or corner seams at a higher functional check if construction warrants it. Record seam opening or yarn displacement after loading, and define a maximum acceptable opening based on the approved sample. On fleece blankets, a buyer may set an internal control such as no visually objectionable seam grin and no seam opening above about 4-6mm at the specified load, but this should be validated against the actual construction during proto.
Body seams and pocket seams should not be treated the same. If the blanket body is hemmed only and the pocket is the functional insertion point, test the pocket after compression/stuffing cycling as well as in an uncycled state. That is where lab-only seam data often fails to predict field performance. If testing budget is limited, spend it on the pocket opening ends and lower corners first.
Compression and stuffing-cycle protocol: make the key claim repeatable
Because repeated self-stowing is the differentiator of this product, add a defined cycle protocol to the buyer spec. This protocol is not a formal ISO blanket standard; it is a repeatable factory and third-party evaluation based on field use. The point is consistency, not theoretical perfection.
A practical protocol is: condition samples for at least 4 hours in a normal test room environment; use 3 trained operators at proto and PPS, and 2 trained QC operators at final inspection; each operator follows the same approved fold map; one cycle equals fold to approved pre-stuff block, invert or open pocket, stuff fully, hold under light hand pressure only, then unpack and open the blanket fully. For compression dwell, place the stuffed blanket under a flat load that gives roughly 1.5-2.5kPa surface pressure for 12 hours, then remove and allow 30 minutes recovery before assessment. Run 10 cycles for proto screening and PPS approval, and a reduced 5-cycle check for routine final inspection unless the buyer requires full verification.
Pass-fail should be explicit. After 10 cycles and compression dwell, no pocket corner split, no bartack tear-out, no opening-end seam burst, no irreversible pocket mouth flare above the approved limit, no permanent diagonal distortion that prevents re-stuffing, and stuffed dimensions remaining within the agreed tolerance after refolding by the approved map. Size recovery on the open blanket should remain within the normal finished-size tolerance, commonly ±3%, after the recovery period.
Inspect defect signatures, not just pass/fail. Common rejection signs are mouth flaring, where the opening bows outward and presents badly at retail; seam grin, where the seam line opens visually before thread break; corner burst, where the lower pocket seam cracks or ladders; and recovery loss, where the blanket retains compression creases or skew that makes the next stuff cycle inconsistent. Those signatures should be photographed at proto and PPS even if the article does not include images.
Decoration: how it changes bulk, fold memory and packed consistency
Decoration on a stuff-pocket blanket is not only a branding choice; it changes local thickness, bending stiffness and inversion behaviour. Buyers should evaluate decoration by its effect on the fold block and on pocket inversion, not only by appearance on the open blanket.
Embroidery gives durable branding and a premium look, but dense fills, heavy backing and high stitch count create hard spots. On 220gsm fleece, that hard spot can add several millimetres of local stack height, push one stuffed face proud and trigger corner-first insertion stress at the pocket mouth. If embroidery is required, keep it away from the central fold spine and the area that must pass through the pocket mouth. A badge or patch on the pocket face can look cleaner than embroidery on deep pile, but it can also reduce inversion smoothness depending on stiffness.
Screen print is usually the least disruptive for packed cube if ink laydown is controlled and the print is kept out of the repeated fold hinge lines. Heat transfer gives crisp graphics but can create a stiffer film area and stronger fold memory, especially on larger logos. Rubber, TPU or silicone patches create the biggest local bulk and the least forgiving cube consistency; they should be used only if the packed-size claim is relaxed or the pocket architecture is upgraded.
Buyer-side guidance: for tight cube targets, prioritise light screen print or small woven label placement. For mid-tier retail with moderate cube control, light embroidery on a non-pocket panel may be acceptable. For dense embroidery, appliqué or rubber patches, increase the pocket allowance, move decoration away from the fold block, or choose a separate pouch format. For broader decoration comparison, see custom blanket decoration methods.
Inspection checkpoints by stage
Freeze different controls at different stages. At proto, settle pocket concept, opening orientation, fold map and decoration location. At SMS, verify fabric hand, loft, GSM and whether the chosen pocket architecture still meets the target stuffed cube. At PPS, freeze the exact fold map, stuffed dimensions, reinforcement details, carton orientation and compression-cycle pass sample. Inline and final should then inspect to that frozen standard rather than re-negotiate the design.
Proto stage checkpoints: confirm open size, fabric GSM on finished body cloth, pocket placement, opening width, seam allowance, SPI, reinforcement method, decoration placement and 10-cycle stuffing/compression result. If the proto fails on packed cube or mouth distortion, do not approve with a verbal promise to 'tighten sewing' in bulk. Change the pattern, opening construction or decoration plan first.
SMS stage checkpoints: verify bulk fabric still sits within the approved GSM and loft band, measure the pocket panel after cutting and after sewing, and run a shortened stuffing check on at least 3 pieces. This is the stage to catch drift caused by fleece finishing changes. If brushing is fuller than proto, the stuffed cube often grows before anyone notices.
PPS stage checkpoints: approve the fold map as a visual work instruction, approve the stuffed-size target on a defined sample count, confirm bartack locations and dimensions, confirm carton count and packing orientation, and record photos of acceptable and reject defect signatures. A PPS without a fold map is incomplete for this category.
Inline checkpoints: check sewn opening width, mouth-end bartacks, lower-corner reinforcement, SPI, seam allowance and first-pass stuffing result at line start and after any operator change. Final inspection checkpoints: use the agreed AQL level, measure stuffed dimensions on the agreed sample size, verify folding to the approved map, inspect for mouth flare, seam grin, corner burst and recovery loss, and confirm carton orientation matches the approved pack method. For AQL framework reference, see AQL 2.5 inspection checklist for 200gsm coral fleece promotional blankets and general process guidance in blanket quality control inspection.
Carton planning: control operator variation before shipment
Carton planning should start from the approved stuffed dimensions and folded pre-stuff block, not from a theoretical CBM model. On this product, operator fold variation can materially change master carton fill and create compression damage if the case pack is too ambitious.
Define pre-pack orientation. A workable method is to place stuffed blankets with pocket face alternating, broad faces vertical or horizontal according to carton footprint, and with the thickest mouth edge alternating to avoid lean. Record the exact orientation on the packing instruction. If the packed cube is not symmetrical, the wrong orientation can add avoidable carton bulge and top-load distortion.
For cube approval, average at least 8 stuffed samples folded by the approved work instruction, ideally by two different trained operators. Record length, width and thickness separately and use the average plus a safety factor, not the best single sample. If one operator can produce a 10% smaller cube than another, that is a process-capability issue, not a shipping surprise to solve with extra carton pressure.
Avoid over-compression in the master carton. As a practical commercial control, if the carton requires strong force to close or if the top panel bows after sealing, the case pack is too high for this construction. Excessive top-load can lock in crease memory, exaggerate mouth flare and promote seam grin at opening ends by the time goods reach the customer. If freight pressure pushes for higher carton count, re-test the stuffed blanket after transport simulation or at minimum after 48 hours in packed condition.
For export assumptions, specify carton count, target carton dimensions, maximum gross weight and palletisation logic if relevant. Many buyers keep gross carton weight below roughly 12-15kg for easier manual handling in this product class, but the right limit depends on channel and destination. If the program ships mixed SKUs or sizes, do not let the factory substitute a different fold map to make carton fit.
Sample PO language buyers can actually use
A short spec block on the PO prevents most of the usual ambiguity. Example wording: 'Product: 100% polyester brushed fleece camp blanket with integrated corner stuff pocket. Body fabric: finished weight 220gsm ±5%, one face brushed/sheared, anti-pill finish as approved PPS. Finished blanket size: 130x170cm ±3%. Pocket: corner-mounted flat self-fabric panel with woven opening facing, finished panel 31x33cm ±1cm, finished mouth opening 27cm ±1cm. Opening ends bartacked 10mm nominal, lower corners reinforced as approved PPS. Pocket seam allowance 10-12mm. Sewing density: 8-10 SPI perimeter, 10-12 SPI facing join. Fold map: exactly per approved visual instruction ref PPS-01. Folded pre-stuff block: 26x28x10cm ±1cm. Stuffed size: 28x30x11cm ±1.5cm each axis; no individual piece to exceed target by >2cm on any axis.'
Add test language separately so the factory and lab do not improvise. Example: 'Critical pocket seams to be evaluated for seam strength by ISO 13935-2 or ASTM D1683 on approved construction; seam slippage at pocket opening and pocket corner to be evaluated by ASTM D434 or equivalent agreed method at specified load against PPS control. Stuffing/compression cycle protocol: 10 cycles at PPS, 5 cycles routine final verification; pass criteria per approved technical sheet.'
For inspection language, a buyer can state: 'AQL major/minor per purchase agreement, with stuffed-size measurement, fold-map conformance and pocket defect inspection included in final random inspection. Final inspection sample set for cube approval to include minimum 8 pieces averaged across at least 2 operators.' That gives the QC house something usable instead of a vague note saying the blanket must be 'packable'.
For care, labelling and claim alignment, keep the PO consistent with the market brief. If the program uses recycled content, anti-pill claims or other compliance language, make sure the claim documents and trim artwork match the actual approval set.
What usually goes wrong and how to catch it early
Mouth flare usually appears first on self-fabric openings cut on the higher-stretch direction, especially after compression dwell. It presents as a bowed opening edge and a loose retail face. Catch it at proto or PPS by comparing post-cycle mouth width and visual shape to the control sample, not just by measuring a flat unfinished pocket.
Seam grin is common where SPI is pushed up on stretchy fleece without changing the opening architecture. The seam may look tight on the sewing line but open visually after stuffing because the fleece structure shifts beside the thread line. Check the opening ends and lower corners after stuffing cycles and after 12-hour packed dwell, not only on fresh-sewn samples.
Corner burst usually starts as local thread stress or fabric distortion at one lower pocket corner where the user forces in the final fold block. Rounded corner geometry, stable opening construction and correct pocket allowance reduce this more effectively than simply adding more thread density. If the corner fails during proto, do not approve a larger bartack alone without rechecking pocket size and fold block.
Recovery loss is a slower defect. The blanket still fits at first approval but progressively loses size recovery and packed consistency after repeated compression. This is often linked to loftier finishing, over-compressed carton packing or decoration in the fold spine. The only reliable way to catch it is a repeatable cycle protocol with a defined recovery period.
Use this as a sourcing baseline, then validate on your actual build
The recommendations here combine common industry practice, standard textile test methods where relevant and field experience from fleece blanket development and inspection. The test methods named above are formal lab methods; the fold-map and stuffing-cycle controls are buyer-manufacturer process controls designed to make a real functional claim inspectable. Buyers should adapt thresholds to the actual blanket size, decoration package, retail positioning and frequency of expected use.
If you need the simplest starting point for a 220gsm retail camp blanket, specify finished body fabric 220gsm ±5%, a corner-mounted flat pocket sized from an approved folded block, a stable opening finish with defined bartacks, stuffed dimensions with tolerance, separate seam strength and seam slippage evaluation, and a 10-cycle stuffing/compression approval protocol at PPS. That is enough to prevent most preventable disputes.
If the brief shifts toward travel, separate pouch packing or compact transport, compare integrated-pocket construction with alternatives such as 280gsm polyester fleece rail travel blankets with elastic luggage straps. If the brief shifts toward backed outdoor use, move to a picnic-mat construction rather than trying to force fleece camp blanket architecture to do a different job. The right specification is the one that matches how the blanket will actually be used, stuffed, packed and inspected.
Frequently asked
What should 220gsm mean for a fleece camp blanket with integrated pocket? For sourcing, 220gsm should normally mean finished body-fabric weight after dyeing and finishing, measured on bulk fabric before cutting. Do not rely on '220gsm' as the finished piece weight. Pocket panel, labels, hemming loss, loft and moisture all affect the net blanket weight. A clearer PO states both body fabric GSM tolerance and a recorded finished-piece average for reference.
What stuffed size tolerance is realistic for an integrated-pocket blanket? For mainstream retail fleece programs, many buyers work with a stuffed-size tolerance around ±1.5cm per axis on the approval average, with no individual piece exceeding target by more than 2cm on any axis. The right tolerance depends on blanket size, fleece loft, decoration bulk and whether folding is done by one trained operator or across a production team.
How large should the pocket opening be? The pocket opening should be set from the approved folded pre-stuff block, not guessed from blanket size alone. On a typical 130x170cm 220gsm fleece blanket, a finished opening around 26-28cm is a workable proto starting point. Tight cube claims, bulky decoration or loftier finishing usually require a wider opening, a more stable facing, or both.
Is seam strength enough to qualify the pocket construction? No. Seam strength and seam slippage are different issues. A pocket seam can show acceptable seam-strength results and still fail in use through seam grin, mouth distortion or slippage after repeated stuffing. Buyers should specify a seam-strength method such as ISO 13935-2 or ASTM D1683 for critical pocket seams and add seam-slippage evaluation such as ASTM D434 at agreed loads, especially around the pocket opening and lower corners.
How should stuffing-cycle testing be written into the spec? Define who folds, how the blanket is folded, how many cycles are run, how long the blanket stays compressed, how long it recovers, and what counts as failure. A practical control is 10 cycles at proto or PPS, 12 hours compressed at roughly 1.5-2.5kPa, then 30 minutes recovery. Failures include corner split, bartack tear-out, seam burst, excessive mouth flare, inability to re-stuff to target size, or permanent distortion outside the agreed tolerance.
Which pocket construction is usually the best balance for 220gsm fleece? For many retail programs, a self-fabric pocket panel with a light woven facing at the opening gives the best balance of cost, packed-shape consistency and durability. A full self-fabric opening is usually the cheapest but is more prone to mouth flare. A full woven pocket body can improve cube control but adds complexity and may create shade or handfeel mismatch.
How does decoration affect packed cube consistency? Dense embroidery, rubber patches, heavy appliqué and large heat transfers can create hard spots that distort the fold block and make one side of the packed blanket bulge. Light screen print and small woven labels usually have the least effect on packed size. If bulky decoration is required, pocket allowance and fold-map layout should be reworked at proto rather than left unchanged.
When should fold map and stuffed size be frozen? Freeze the concept at proto, verify it at SMS, and formally lock the exact fold map, stuffed dimensions, reinforcement details and packing orientation at PPS. Inline and final inspection should measure against that frozen standard. Leaving fold sequence open until final inspection creates operator variation and makes carton planning unreliable.
