Rolled navy polyester fleece travel blankets secured with black elastic straps, measured with a diameter gauge and packed into export cartons on a factory QC table

Start with service conditions, then lock the commercial definition

A typical enquiry sounds simple: 3,000 travel blankets, dark navy, rolled with an elastic strap, FOB Ningbo. The buying risk sits in six linked variables: fleece construction, finished size, finished blanket mass, shipped unit mass, rolled diameter, and strap durability. Leave those vague and two suppliers can quote the same nominal 195gsm while delivering different warmth perception, different carton counts, and different in-service failure rates.

For bus and coach fleets, finished size is commonly 120x150cm for lap use or 130x170cm for shoulder-to-knee coverage. On 130x170cm, fabric area is 2.21m². At 195gsm nominal, the calculated fabric mass is about 431g before thread, labels, strap, and bag. The finished blanket mass is typically around 440-452g including blanket body, sewing thread, care label, brand label, and sewn strap, but excluding the polybag. The shipped unit mass is typically about 445-458g when an individual PE bag is included. Buyers should keep those three numbers separate in the PO; otherwise one quote may be based on fabric only while another includes strap and bag.

If compact onboard storage is the first priority, compare this rolled format with lighter fold-packed travel builds such as 185gsm polyester airline blankets with ultrasonic center-fold lines. A 195gsm rolled blanket usually gives a fuller hand and better perceived warmth than airline-grade product, but the trade-off is higher bulk and a lower pieces-per-carton count. That trade-off should be visible at RFQ stage, not discovered after packing trials.

Use an RFQ-ready commercial description buyers can paste into a PO

A procurement-safe description for this item is: 100% polyester circular-knit polar fleece travel blanket, one-side brushed and one-side anti-pilling minimum, piece dyed navy, nominal fabric mass 195gsm, finished size 130x170cm, four-side overlock edge, one sewn black elastic roll strap, individually packed in PE bag, FOB Ningbo. That is tighter than simply writing '195gsm fleece blanket with strap'.

The reason to specify one-side brushed and one-side anti-pilling minimum is commercial as much as technical. Two-side anti-pilling can improve surface retention, but it usually adds finishing cost and often produces a slightly flatter, less plush hand at this weight. One-side brushed / one-side anti-pilling is a common middle ground for fleet use: the face keeps a fuller hand, the reverse resists fuzzing better during repeated rolling and contact, and the price stays below many two-side anti-pilling programmes. If a mill proposes two-side brushed or two-side anti-pilling, ask for that as a separately priced option rather than an uncontrolled substitution.

Avoid an open-ended yarn statement such as '75D or 100D depending mill route'. A better rule is: approved base route either 75D/144F filament fleece for softer hand and lower roll bulk, or 100D/144F filament fleece for fuller loft; no substitution after approval without buyer sign-off. In practice, the exact difference in rolled diameter varies by knit density, brushing depth, shearing, moisture regain, and folding method. Rather than claiming a fixed 0.5-1.0cm saving, require a pre-production packing trial using the approved fabric route and measured roll method. That trial, not a brochure claim, should control carton count.

For buyers comparing adjacent travel or gifting programmes, the broader hand-versus-weight trade-off is covered in fleece weight throw blanket program.

Set a clear decision hierarchy for GSM, blanket weight, and acceptance

Use one acceptance hierarchy instead of overlapping bands. For this item, the practical control sequence is: fabric GSM controls mill approval, finished blanket mass controls production consistency, and shipped unit mass controls commercial packing verification. Shipment acceptance should follow the agreed lot-average requirement, not a separate contradictory tolerance.

A workable fleece GSM rule is: condition specimens for 24 hours at 20±2°C and 65±4% RH, which is the standard atmosphere used in textile testing and should be treated here as mandatory conditioning for buyer-supplier control. Then cut and weigh 5 specimens per colour lot, distributed across width and along the roll. Acceptance: lot average 195gsm ±4%, meaning 187-203gsm, with no individual specimen outside 195gsm ±6%, meaning 183-207gsm. If the lot average fails, the lot fails, even if some individual pieces pass. That removes the earlier overlap between specimen, lot average, and shipment average logic.

For finished blanket mass, sample 10 finished pieces per inspection lot. Acceptance: finished blanket mass average 440-452g excluding polybag, and shipped unit mass average 445-458g including polybag. If commercial settlement is based on shipped unit mass, state that explicitly. Do not allow a supplier to swap between fabric-only and packed-unit weights after the quote is issued.

For finished size, measure after the blanket rests flat for at least 12 hours at room condition without stretching. A practical tolerance is width ±2cm and length ±3cm per piece, with lot average not below nominal minus 1cm on either dimension. For many fleet buyers, a short blanket is more objectionable than a slightly heavy blanket because coverage complaints start immediately in service.

Define construction, edge sewing, and appearance retention by method

For this weight class, a good baseline is 100% polyester circular-knit polar fleece, 195gsm nominal, four-side overlock edge, thread count and density matched to avoid edge tunnelling and grin-through. Overlock is usually the most efficient edge finish for a bus fleet blanket because it controls fray, keeps cost moderate, and adds less perimeter bulk than a folded hem.

Appearance retention should be written against a test method rather than generic wording such as 'good anti-pilling'. A workable benchmark is ISO 12945-2 Martindale pilling, minimum grade 3.5 after 2,000 rubs on the anti-pilling side and grade 3.0 minimum on the brushed side. That is realistic for a medium-weight transport blanket; asking for grade 4.5 at this cost level often pushes finishing cost without proportional service gain.

For colourfastness on dark navy, specify ISO 105-X12 rubbing fastness at dry 4 minimum, wet 3 minimum, and ISO 105-C06 wash colour change/staining at grade 4 minimum under the agreed domestic laundering procedure. Dark fleet blankets that crock onto light uniforms or light seat trim create faster complaints than small weight drift.

If buyers want a lighter or more compact benchmark to compare pack density, the adjacent travel category in 140gsm brushed polyester airline blankets with heat-cut edges is useful as a lower-bulk reference point.

Specify the strap as a controlled component

The strap is not a trim detail. It is the closure system and one of the first service-failure points. A practical default is latex-free knitted polyester-elastane elastic, black, 28-30mm finished width, typically 1.4-1.8mm thickness. Polyester-rubber elastic may be cheaper, but many buyers reject it because ageing, odour, and latex-policy questions become harder to manage across destination markets.

A usable component spec is: 30mm nominal width, width tolerance ±2mm, thickness 1.4-1.8mm, relaxed loop circumference matched to approved roll standard, overlap join 20-25mm minimum, heat-cut ends buried within overlap, sewn by lockstitch box plus bartack or dense bartack only. Reject butt-joined elastic, exposed cut ends, narrow 20mm elastic on this blanket size, or attachment positions that twist the roll off-centre.

Define the strap attachment seam by a seam method, not by ASTM D5034, which is a grab tensile test for fabric and does not validate seam integrity. For the sewn join, use a seam-strength or seam-slippage method such as ISO 13935-2 for seam tensile behaviour on the stitched assembly, or an agreed buyer-supplier component pull method if the geometry does not suit a standard seam specimen cleanly. If a formal method is required in the PO, write the exact specimen preparation with the strap sewn into the fleece assembly.

If the buyer wants a closure with lower elastic ageing risk and easier component replacement, compare this build with 190gsm polyester fleece blankets with RPET webbing straps. Webbing usually packs less neatly around a small-diameter roll but can outperform elastic in long-term recovery.

Use enforceable house methods for strap cycling and attachment pull

For a travel blanket strap, a house method is acceptable if it is written fully and treated as mandatory. The service logic is simple: housekeeping stretches the loop every time the blanket is re-rolled. A realistic control method is: condition samples 24 hours at 20±2°C and 65±4% RH; test 5 straps from pre-production and 5 from bulk; extend each loop to 150% of relaxed loop length; hold 5 seconds; relax 5 seconds; repeat for 100 cycles. After cycling, allow 30 minutes unloaded recovery before re-measuring relaxed length.

Acceptance for that cycling screen can be: average permanent growth not over 8%, no individual over 10%, no broken elastic yarns, no seam cracking, no bartack rupture, and the strap must still retain the approved test roll during three lift-and-shake cycles. This is not a universal life test; it is a pre-shipment control tied to the approved roll format.

For strap attachment strength, define a pull test as a component test. One workable method is: prepare 5 finished blankets; roll each blanket per the approved method; clamp the blanket body; apply a tensile load to the strap attachment up to 70N; hold 10 seconds; inspect for stitch breakage, seam opening, strap pull-out, or visible fleece tearing at the attachment point. Acceptance: 0 failures out of 5, with no seam opening greater than 3mm after load release. If buyer handling is rougher or the blanket is larger than 130x170cm, many importers push this screen to 90N, but the load should be agreed before costing because higher acceptance loads may require more stitch density or reinforcement patches.

Where buyers want a more formal seam benchmark on sewn blanket components, the logic in ASTM D5034 seam strength targets for fleece stadium blankets is still useful as context, but the PO should not cite D5034 as proof of seam integrity for this strap attachment.

Control rolled diameter with a repeatable method, not operator judgement

Rolled diameter is a freight-cost variable. For a 130x170cm blanket in 195gsm medium-pile polar fleece, a practical production range is often around 13.5-15.5cm diameter and 42-45cm roll length, but the actual result depends on yarn route, brushing, finishing moisture, fold pattern, strap tension, and whether the roll is measured bare or bagged. Those variables must be frozen before bulk.

Write the roll-diameter method tightly: blanket laid face side down; folded lengthwise into three equal panels with edge alignment tolerance within 10mm; rolled from the short end by the same trained operator or operators qualified against a golden sample; secured with approved strap only; rested 10 minutes without load; measured at the midpoint and both ends; average of three readings recorded. Use a diameter gauge or caliper with ±1mm tool tolerance. State clearly whether the measurement is taken without polybag or with the individual polybag applied. For carton fit, the more useful control is usually with polybag, because bag film and trapped air change fit materially.

A practical acceptance rule is average packed roll diameter 14.0-15.0cm, no individual over 15.5cm, and roll length 42-45cm. Do not promise a fixed carton count change from a given diameter increase unless it has been proven by trial. Instead, state that carton count must be verified by pilot pack-out because even a small average diameter increase can trigger either carton bulge or a drop in pieces per carton, depending on bag thickness, roll stiffness, and carton board performance.

If the project is highly freight-sensitive, compare the packed bulk of this rolled fleece item against lighter compact travel builds such as 190gsm RPET microfleece travel blankets with elastic belly straps.

Worked packing example: unit dimensions, carton maths, and total CBM

Below is a realistic worked example for 3,000 pieces based on an approved 130x170cm blanket, 195gsm fleece, one sewn elastic strap, and individual PE bag packing. This is an example for planning, not a universal guarantee: approved packed roll size 14.5cm diameter x 43cm length per piece, measured with polybag. Individual bag: PE 0.03mm thickness, vent holes permitted, printed suffocation warning only where destination market requires it. Unit shipped mass: 451g average.

Carton plan example: 20 pieces per export carton, packed in two layers of 10 rolls. Carton internal fit must be confirmed in pilot packing, but a typical outer carton may be 75 x 45 x 60cm. At that size, CBM per carton = 0.75 x 0.45 x 0.60 = 0.2025m³. For 3,000 pieces at 20 pieces per carton, total cartons = 150 cartons. Total volume = 150 x 0.2025 = 30.375m³.

Weight example: blanket and strap finished mass about 446g; PE bag about 5g; unit net weight 451g. For 20 pieces, net weight per carton = 9.02kg. If the export carton, tape, and carton markings add about 1.0-1.3kg, then gross weight per carton is typically around 10.0-10.3kg. Total shipment net weight for 3,000 pieces is about 1,353kg; total gross weight is likely around 1,500-1,545kg depending on carton board grade and exact bag weight.

If a supplier claims 24 pieces per carton at the same rolled size, ask for a witnessed pilot pack-out with the specified bag thickness and carton burst grade. In many cases, a 24-piece claim depends on either under-filled rolls, thinner bags, or carton compression that is acceptable for loading-day photos but not for transit. Freight-normalised comparison matters more than FOB headline price. Buyers planning mixed-SKU loads should also review custom blanket lead times shipping.

State packaging assumptions and market-label details explicitly

Unit packing affects both mass and carton density, so it belongs in the PO. A practical default is: 1 piece per individual PE bag, 0.03mm thickness nominal, clear or printed as approved, with vent holes. Vent holes reduce trapped air and improve carton fit on rolled fleece products. If the buyer wants a cleaner retail look without vent holes, require a pilot pack test because trapped air can increase carton pressure and make carton closing inconsistent.

Warning labels depend on market and channel. Individual polybags sold into some retail or e-commerce channels may require suffocation warning text; for business-to-business bulk shipment where the bag is not consumer-facing, the buyer may allow master-carton-only packing or no individual bag at all. The PO should state whether the bag is individual consumer pack, transit protection only, or master-pack only. If the goods may enter FBA or parcel channels later, that decision should be made before bulk starts, not after production is finished.

Carton requirements should be quoted separately: board type, burst or compression expectation, carton dimensions, carton weight limit, and palletisation if applicable. For medium-weight fleece travel blankets, many buyers keep gross carton weight below about 12kg for easier handling. If high stacking or long export transit is expected, ask the supplier to quote the carton burst requirement or board grade instead of assuming a standard export carton is enough.

Add AQL settings that inspection can actually apply

If the article claims AQL checkpoints, the plan must define the inspection level, AQL values, and defect classes. A practical framework for this item is: ANSI/ASQ Z1.4 single sampling, General Inspection Level II, lot-size based sample size, with Critical 0, Major 2.5, Minor 4.0. That is common for mid-value textile programmes, though some fleet buyers tighten majors to 1.5 on dark colours or first orders.

Examples of critical defects: prohibited contamination, sharp foreign object, incorrect legal labeling where safety or market compliance is affected, or severe odour suggesting chemical contamination. Major defects: wrong finished size beyond tolerance, wrong colour versus sealed standard, roll diameter over maximum, strap attachment failure, broken stitching, hole, tear, obvious oil stain, missing strap, missing care label, wrong carton count, or gross carton deformation. Minor defects: slight seam waviness, small loose thread, light shade variation within approved tolerance, minor bag print misalignment, or small non-functional cosmetic issues.

For inspection execution, state the lot basis. Example: inspection lot = one shipment, one colour, one construction, one PO line. Weigh, size-check, roll-check, and strap-check within the same AQL sample, then perform destructive strap pull and recovery tests on a separate agreed subset. Buyers wanting a deeper checklist can cross-reference blanket quality control inspection and AQL 2.5 inspection checklist for coral fleece promotional blankets.

Compliance notes should match destination market and use case

For a general adult travel blanket, buyers commonly request declarations or test support for REACH Annex XVII restricted substances, SVHC communication, and azo dye restrictions. Those are not interchangeable. REACH Annex XVII covers restricted substances with legal limits in scope products; SVHC obligations concern candidate-list substances above reporting thresholds in articles or components; azo dye requests are often handled either as a buyer RSL requirement or as part of destination-market chemical compliance.

For dark dyed polyester fleece and elastic straps, practical documentation often includes: supplier declaration for REACH Annex XVII, SVHC statement against the current candidate list, and azo dye declaration or test where buyer RSL requires it. If the strap, ink, or bag contains additional components such as PVC, phthalate review may also be requested. Whether formal third-party testing is required depends on destination market, retailer protocol, and whether the blanket is sold as a consumer product, amenity item, or institutional textile.

If the item is for children, promotional giveaway, bedding, or a regulated transport environment, extra requirements may apply, including CPSIA-type reviews, tracking label demands, or buyer-requested flammability checks. For adult bus operator use, those are not automatic. The PO should say compliance requirements subject to destination market and end use, to be confirmed before bulk. Buyers needing a broader framework can review textile certifications explained buyers.

Pre-production approval workflow that prevents expensive bulk mistakes

A useful approval workflow for this item has five gates. 1) Lab dip or shade swatch approval under the agreed light source, commonly D65, with nap direction stated during judgement. 2) Handfeel and roll standard approval using the actual approved yarn route and finishing route. 3) Sealed counter-sample signed by both parties, showing size, edge sewing, strap position, and label set. 4) Pilot carton pack-out using actual polybag thickness and actual export carton. 5) Golden sample for strap recovery retained at the mill and by the buyer for comparison during bulk inspection.

Do not approve bulk from a fabric hanger alone. A hanger cannot validate roll diameter, closure recovery, or carton fit. On rolled travel blankets, the pilot pack-out is often the stage where hidden differences show up: softer fleece may roll larger, a different bag film may trap more air, or a strap loop set too loosely may look acceptable at the sewing line but fail the shake test after 100 cycles.

Bulk should not start until the commercial description, tolerances, packing clause, and approved standard sample all match. That sounds procedural, but it is usually cheaper than reworking thousands of straps or replacing cartons after a failed loading test.

Buyer-ready clauses to paste into the RFQ or PO

Commercial description: 100% polyester circular-knit polar fleece travel blanket, one-side brushed and one-side anti-pilling minimum, piece dyed navy, nominal fabric mass 195gsm, finished size 130x170cm, four-side overlock edge, one sewn black latex-free polyester-elastane elastic roll strap, individual PE bag packing, FOB Ningbo.

Finished size: width ±2cm, length ±3cm per piece, lot average not below nominal minus 1cm. Finished blanket mass excluding polybag: average 440-452g. Shipped unit mass including polybag: average 445-458g. Packed roll size measured with polybag: diameter average 14.0-15.0cm, no individual over 15.5cm; roll length 42-45cm.

Inspection plan: ANSI/ASQ Z1.4, General Inspection Level II, single sampling, AQL Critical 0, Major 2.5, Minor 4.0, lot basis one shipment / one colour / one PO line. Major defects include wrong size, wrong shade, strap failure, hole, severe stain, missing label, wrong carton count, packed roll over max diameter, or carton deformation. Destructive tests on separate subset: strap cycling 5 pre-production + 5 bulk; attachment pull 5 finished pieces, 70N x 10s, 0 failures.

Packaging clause: One blanket per PE bag, 0.03mm nominal thickness, vent holes unless otherwise approved, suffocation warning text only where destination market requires it, 20 pieces per export carton pending approved pilot pack-out, target outer carton 75 x 45 x 60cm, gross carton weight not to exceed agreed limit, carton board grade or burst requirement to be stated on quotation. Supplier must quote unit net weight basis, bag inclusion, carton dimensions, carton tare, and total CBM for the order quantity.

Supplier quotation comparison checklist

Before awarding the order, ask each supplier to quote the following items separately so you are not comparing unlike-for-like offers: approved yarn route (75D/144F or 100D/144F), fabric GSM tolerance, finished blanket mass basis, unit shipped mass basis, strap composition and width, individual bag thickness, packed roll diameter target, pieces per carton, carton size and board grade, total CBM, and test inclusions.

Also ask whether the quote includes pre-production lab dip, sealed sample, pilot carton test, and compliance paperwork. A lower FOB is less attractive if the supplier is excluding strap recovery testing, quoting body weight without the bag, or assuming a weaker carton than the shipment requires.

For buyers sourcing multiple blanket categories at once, it also helps to compare closure and packing strategies across nearby products such as specifying 180gsm microfleece travel blankets with nylon carry pouches and travel airline blanket weight packing.

Frequently asked

What is the right weight basis to use when comparing supplier quotes for a 195gsm travel blanket? Use three separate numbers: calculated fabric mass, finished blanket mass, and shipped unit mass. For a 130x170cm blanket at 195gsm, calculated fabric mass is about 431g. Finished blanket mass usually lands around 440-452g with strap and labels but without bag. Shipped unit mass is often around 445-458g with an individual PE bag. If suppliers quote different weight bases, the FOB comparison is not clean.

Is one-side brushed and one-side anti-pilling a cost-down construction? It is usually a cost-performance choice rather than a pure downgrade. One-side brushed keeps a fuller hand, while the anti-pilling side helps service appearance on the surface that sees more rolling and contact. Two-side anti-pilling can improve retention but often costs more and may flatten the hand slightly. For bus fleet programmes, the one-side brushed / one-side anti-pilling route is often the better commercial balance.

Which test should be used for the strap attachment seam? Do not use ASTM D5034 as proof of seam integrity. ASTM D5034 is a fabric grab tensile test. For the strap attachment, use a seam-strength or seam-slippage method such as ISO 13935-2 where the specimen geometry suits the construction, and add a product-specific attachment pull test on finished blankets, for example 70N held for 10 seconds on 5 samples with zero failures.

How should roll diameter be measured for a travel blanket with elastic strap? Freeze the method in the PO. State the folding orientation, operator controls, rest time, tool tolerance, and whether the roll is measured with or without polybag. A practical method is three-panel lengthwise fold, roll from the short end, strap closed, 10-minute no-load rest, then measure midpoint and both ends with a gauge accurate to ±1mm. For carton-fit control, measuring with the polybag is usually more useful than measuring the bare roll.

What AQL settings are reasonable for this type of blanket? A common starting point is ANSI/ASQ Z1.4, General Inspection Level II, single sampling, Critical 0, Major 2.5, Minor 4.0. Major defects normally include wrong size, wrong shade, strap failure, hole, severe stain, wrong carton count, missing label, or packed roll diameter above the agreed maximum. Buyers may tighten majors to 1.5 on first orders or dark shades.

What compliance paperwork should buyers usually ask for? For an adult travel blanket, buyers often ask for REACH Annex XVII declaration, SVHC statement against the current candidate list, and azo dye declaration or testing if their restricted substances list requires it. Extra items such as CPSIA-type review, phthalate review, or flammability checks depend on destination market, sales channel, and end use. Those requirements should be confirmed before bulk starts, not after production is complete.
