TPU Hot Melt Adhesive Film

TPU Hot Melt Adhesive Film for No-Sew, Wash-Durable Elastic Bonding

Sportswear elastic bands can stretch out within months of purchase. Poorly bonded seams, built with less ideal grades of hot melt film, fail in the wash or the heel counter breaks through after the very first wear. Teng Yang’s TPU hot melt adhesive film can replace both methods, forming a wash-durable and flexible bond line that stretches along with the material, rather than against it. The film bonds quickly without need of needle, leaving behind no seam allowance or entry point for moisture.

Teng Yang supplies 7 grades of TPU hot melt adhesive film (65°C to 130°C melt point) for textile, automotive interiors, and footwear applications. We ensure the EU RoHS compliant standards of SGS’s certification process for each product grade.

TPU Hot Melt Adhesive Film Material Extrusion Detail — Commodity-grade hot melt film used in sports wear elastic bands doesn’t hold elasticity, or soft drape of the material after a few months of wear11. Traditional methods such as stitch, leave wear points, stitch holes and a stiff seam allowance that resists the stretch of athletic fabric. Liquid adhesives and glues, that require long dry times and introduce the use of volatile organic compounds and improper wetting, have also been common.

TPU Hot Melt Adhesive Film Substrate Bonding State — Teng Yang’s TPU hot melt adhesive film avoids the shortcomings of each; forming a solid film that melts quickly and bonds in seconds when heated under pressure, allowing for evenly wetted substrate surfaces and even application of adhesive. The secret lies in TPU’s inherent physical (as opposed to chemical) cross-linking between soft segments and hard segments within its polymer structure — the key reason EVA and other hot melt chemistries can’t be reheated and re-bonded, or match TPU’s elongation recovery1. This bond-only approach follows a documented shift away from stitched seams described in Chinese Patent CN102441973A, resulting in failed bonds.

ENGINEERING NOTE

Why “One TPU Grade” Doesn’t Exist

It isn’t unusual to find disparate melt temperature processing ranges cited for the same product category of TPU hot melt adhesive film-even by suppliers with established products. You’ll see recommended processing windows ranging anywhere from 40-120°C for initial melt, or 100-200°C overall working temperatures, or 110-160°C specific hot press temperatures. Those numbers reflect not industry sloppiness, but rather distinct low-melt, mid-melt, and high-melt grade families optimized for various materials. Standard TPU can yellow over time from exposure to UV unless an anti-yellowing additive is used for highly visible areas. Don’t put too much faith in single, broad temperature figures from “industry standard” data sheets- always rely on Teng Yang’s specific grade datasheets.

Teng Yang TPU Hot Melt Adhesive Film, Models & Specifications

A typical query from new users is “what’s the” specification for a TPU hot melt film adhesive – and asking for “the” specification betrays the inherent issue; a single grade won’t be appropriate for a low melt, delicate fabric 65°C application, and a high melt, automotive 130°C headliner application, since each end of that range is a real compromise in the polymer’s activation window. It’s for precisely that reason that Teng Yang makes product over the entire range; trying to force a single grade to do everything requires under-bonding in one end, and cooking material in the other.

Decision Matrix, Which Melt-Point Band Fits Your Line?

Melt Band	Grades	Best Fit	Why
Low (65°C)	TB65 / TBE65 / TBL65	No-sew underwear, delicate/lycra fabric, footwear uppers	Fast activation, low thermal load protects heat-sensitive fabric
Medium (95°C)	TB95	General textile lamination, embroidery backing, garment accessories	Balanced activation window, widest general-purpose fit
High (115–130°C)	TB115 / TBK115 / TB130	Automotive interior trim, headliners, fire-retardant material bonding	Withstands >100°C solar-heat cabin exposure without softening

Those who specify interior car trim may be interested in seeing that even within the high-melt region, there are various requirements depending on component – headliner: resistance to 100C+, to allow exposure to solar loading; door-panel lamination: draw-down/vacuum-forming suitability; carpet/insulation adhesion: firm bond to irregular, “dirty” chassis substrate; etc – so that one high-melt resin wouldn’t typically be suitable.

TPU vs EVA vs PA Hot Melt Film, Which Chemistry Fits Your Application?

More than likely your procurement team defaults to EVA hot melt film due to EVA’s low activation temperature and low per-roll cost. That default works in the economy range for lamination but fails to account for how TPU’s higher unit cost is offset, primarily through better wash durability and recovery upon elongation of stretch material, where EVA bonds usually pull apart long before TPU bonds will.

Process Assessment

Sometimes, alternative chemistries like reactive PUR hot melt adhesive are considered less expensive than TPU hot melt film. Reactive PUR isn’t a like-for-like replacement, though: it has between 2-5% free isocyanate monomer (usually 4,4’-MDI, a respiratory sensitizer) and requires moisture-barrier packaging plus multi-day cure times, per the background section of US Patent US20170058163A14. TPU hot melt film is non-reactive, cures in seconds, and contains no free isocyanate monomer — a genuine safety and process-ease factor, not just a sales pitch.

Quality Assurance

Every grade Teng Yang’s factory produces undergoes complete third-party chemical certification (SGS), backed by years of production experience — unlike converters who lack in-house testing resources.

Applications & Manufacturing Capability

TPU hot melt adhesive film bonds at our facility in nine major industrial application groups: clothing and accessories, footwear, automotive, electronics and electrical applications, medical supplies, building and construction, packaging, sporting equipment, and other consumer products including bags, packs and outdoor recreation goods. Even temperature sensitive and high service temperature substrates need to be paired with the proper hot melt temperature range – while all hot melts will degrade with temperature increase hot melts in use above their listed service range is one thing for a supplier conversation and another for a guess5.

40% LESS

Restrictive stretch resistance vs. sewn seams, with equal-or-greater bond strength in lab and field testing

Source: Industry-wide heat-sealed seam testing (industry-wide bond-only vs. sewn-seam data, not an internal lab study)

No-Sew Garment & Footwear Construction

Independent industry testing on heat-sealed, bond-only seam construction (vs. traditional sewn seams) found bonded seams up to 6% lighter than sewn seams, with 50-60% less water absorption when wet, and up to 40% more flexible – while lab and field testing showed bonded seams held equal or greater strength than sewn seams, with the surrounding fabric giving way before the bonded seam did6. That combination – lighter, more water-resistant, and no less durable – is why bond-only construction has moved from a niche technique to the default in performance-wear waistbands, no-sew underwear, and outdoor-jacket seam sealing.

Manufacturing Capability

Our factory covers the full process chain for automotive, textile, and footwear customers alike, from raw material to finished roll: lab-scale material testing, pelletizing, film casting, blown-film extrusion, coating, slitting, and rewinding — a sequence consistent with the co-extrusion and coating process described in Patent CN102441973A. Each stage is run under the same quality system, built up over years of production, that produced the RoHS-verified TPU hot melt adhesive film batch documented below – unlike converters who buy in film from a third party and simply relabel it, our facility controls every stage in-house.

Certifications & Compliance
SGS-Verified RoHS Compliance

Sibling product TPU Hot Melt Adhesive Web (same polyurethane chemistry family, different construction format) separately passed the identical RoHS 2015/863 test panel — SGS Report No. SHAEC23011705801, issued 2023-08-04

Additional quality certifications available on request, evaluated against frameworks such as ISO 9001:2015

Laboratory Test Verification

Our TPU Hot Melt Adhesive Film has been independently tested by SGS-CSTC Standards Technical Services (Shanghai) under EU RoHS Directive 2015/863 (amending Annex II to Directive 2011/65/EU) – covering lead, mercury, cadmium, hexavalent chromium, PBBs, PBDEs, and four phthalates (DEHP, BBP, DBP, DIBP).

Result: Pass Report No. SHAEC23003710501 (issued 2023-04-06)

< HOVER

HOVER >

Why an RoHS pass matters more than it might look: an ECHA review of REACH compliance in 2022 found 23% of inspected companies failed to meet REACH registration or safety-data requirements7 – third-party test verification, not a self-issued datasheet claim, is what separates a documented compliance record from a marketing assertion. Unlike a supplier who only shows a certificate logo on their homepage, Teng Yang publishes the actual SGS report number so you can request the full document directly – the honest version of a compliance claim is one you can independently check.

How to Order, MOQ, Lead Time & Customization

What to Confirm Before You Order

Minimum order quantity and lead time both scale with grade, thickness, width, and any custom formulation work (color, release-paper option, or slitting to a non-standard width) – we don’t quote a single fixed number because a stock-width low-melt grade and a custom-slit high-melt grade genuinely ship on different timelines. Send us your substrate, target melt-point band, and volume, and we’ll return firm MOQ and lead-time numbers for that specific configuration.

International orders – including the HS code classification your customs broker will ask for – are typically structured under Incoterms 2020, the International Chamber of Commerce’s standard set of 11 three-letter trade terms that define which party handles which shipping tasks, costs, and risks. Incoterms clarify logistics responsibility; they don’t fix price, MOQ, or lead time on their own, which is exactly why those figures are confirmed per quote rather than published as a flat rate the way some suppliers imply.

What to Ask Any TPU Hot Melt Film Supplier (Not Just Teng Yang)

Peel-strength data by substrate combination
Activation-temperature tolerance and thickness tolerance across the roll width
Batch-to-batch consistency records — not just a sample-stage pass

A Real Red Flag Worth Noting

A supplier who avoids detailed process discussion or delays documentation requests can just as easily mean the batch consistency isn’t there yet. Over 80% of procurement officers treat ISO 9001 certification as a baseline requirement when vetting chemical and adhesive suppliers – ask early, not after the first bulk shipment.

Is TPU hot melt adhesive film the same as TPU film?

No. TPU film is pure TPU resin, ready to use without heating, typically made by blow-molding or casting2. TPU hot melt adhesive film is a composite of TPU resin plus tackifying resin, supplied as granules or coated rolls that must be heat-melted to bond. They share a base polymer family but are different products for different jobs2.

Why does TPU cost more than EVA hot melt film?

TPU’s higher unit price reflects its wider elasticity range, stronger chemical/oil resistance, and better wash-cycle durability on stretch fabric – properties that matter for performance apparel and footwear but are often unnecessary for lower-stress, economy-grade lamination, where EVA remains a reasonable choice.

How do I choose between the low, medium, and high melt-point grades?

Match the grade to your most heat-sensitive input material, not to your press equipment’s maximum temperature. Delicate fabrics like silk or lycra call for a low-melt grade (around 65°C) to avoid fabric damage during lamination; general textile and footwear work is well served by the medium band; automotive interior components exposed to solar heat need the high-melt band.

Does TPU hot melt adhesive film come with or without release paper?

Both. Backed film is easier to position by hand; bare film suits roll-to-roll lines.

How can I verify a grade’s melt point matches the datasheet before a bulk order?

Ask for a pre-production sample and press it at the datasheet-specified temperature and dwell time on your actual substrate, then check bond strength before and after a wash cycle relevant to your end use. This is the same protocol used in formulation testing: press onto the target fabric, then measure peel strength before and after washing, not just at time zero.

Is TPU hot melt adhesive film RoHS and REACH compliant?

Our TPU hot melt adhesive film passed independent SGS tests according to EU RoHS Directive 2015/863 (Report SHAEC23003710501). We will not claim a certification we can’t supply a report for — contact our team for the latest REACH declaration for your order region.

What’s the difference between TPU hot melt film and hot melt web/mesh?

Film is a solid sheet – better for high stress structural bonding, but has lower air permeability. Web/mesh is a spun, non-woven like structure, it has more breathability and is often used when the bonded panel still needs to breathe (think: underwear, yoga wear, technical base layers).
