EVA vs. TPU Hot Melt Adhesive Film — What’s the Difference?
|
Attribute
|
EVA Hot Melt Adhesive Film
|
TPU Hot Melt Adhesive Film
|
|---|---|---|
|
Polymer Base
|
Ethylene-Vinyl Acetate (EVA) copolymer
|
Thermoplastic Polyurethane (TPU)
|
|
Activation Temp.
|
Lower — typically 110–130°C (some grades to 140°C)
|
Higher — typically 130–160°C+
|
|
Fabric Suitability
|
Delicate / heat-sensitive textiles (chiffon, mesh, lightweight knits)
|
Broader — including leather, heavier synthetics, high-wash items
|
|
Hand Feel After Bond
|
Very soft, low modulus — minimal stiffness added
|
Slightly firmer but still flexible; higher elasticity
|
|
Wash Durability
|
Good for domestic wash (30–40°C typical); less chemical/oil resistance than TPU
|
Excellent — often rated 40–60+ washes, better oil/sweat resistance
|
|
Clarity
|
High transparency — nearly invisible on most fabrics
|
Clear to slightly hazy depending on grade
|
|
Cost Position
|
Generally lower — economical for high-volume garment trims
|
Premium — justified by elasticity & durability on performance wear

-
Thickness Options: 0.05 mm / 0.08 mm / 0.10 mm / 0.15 mm / 0.20 mm (custom thickness available)
-
Activation / Bonding Temperature: Low-temperature activation — typical press 110–130°C (230–266°F); adjust dwell time per substrate
-
Recommended Press Time: 8–15 seconds (depends on temp & fabric density)
-
Pressure: Medium (3–4 bar / 40–50 psi on swing-away press)
-
Peel Method: Warm peel generally recommended; test hot vs. cold peel on your fabric
-
Roll Supply: Standard 128 m² per roll; custom widths (e.g., 50 cm / 100 cm / slit rolls) on request
-
Carrier / Release Liner: Siliconized PET release liner for clean weeding & positioning
-
Eco Compliance: Non-toxic, phthalate-free, conforms to OEKO-TEX® Standard 100 (on request)
-
Adhesion Substrates: Cotton, polyester, nylon, spandex blends, non-woven interlinings
Typical Applications in Garment & Accessory Production
1. Garment Label & Brand Tag Bonding
2. Embroidery Patch / Appliqué Backing & Lamination
3. Interlining / Facing Fixation
4. Logo Transfers on Delicate Shell Fabrics
5. Craft & Promotional Item Assembly
Correct Application for Reliable Bond & Fabric Safety
-
Pre-Test on Scrap Fabric: Always run a sample on the actual garment fabric to confirm activation temp — start at 110°C / 12 s / medium pressure and adjust upward in 5°C increments if bond is weak.
-
Use a Protective Sheet: Place a silicone release paper or Teflon sheet between the press platen and the film’s release liner during fusing to avoid liner adhesion to the upper platen.
-
Allow to Cool Slightly Before Peeling Liner: For warm-peel grades, wait 2–5 seconds post-press; if edges lift on a textured knit, allow full cool before removing the carrier.
-
Store Rolls Properly: Keep in original polybag away from direct sunlight and humidity; EVA can absorb moisture over long storage which may affect bubble formation during activation — a short pre-dry (room temp, low humidity) helps if rolls have been stored > 6 months in humid climate.
-
Wait 24 h Before First Wash: Full bond strength develops as the adhesive cools and crystallizes.
Sourcing Checklist for B2B Buyers & Apparel Manufacturers
-
✅ Specify thickness (0.05 / 0.10 / 0.15 / 0.20 mm etc.) based on substrate weight — thinner for labels on sheer fabrics, slightly thicker for patch bonding.
-
✅ Confirm roll width & length — standard 100 cm or 50 cm slit; custom slit widths available.
-
✅ Ask for sample swatch book (includes multiple thicknesses) for in-house press validation.
-
✅ Inquire about OEM / private label packaging if reselling under your brand.
-
✅ Request technical data sheet + MSDS / compliance certs (OEKO-TEX®, REACH, RoHS as applicable).
