Why Low Activation Temperature (110–130°C) Matters for Sensitive Substrates
-
Fabric Heat Sensitivity: Polyester chiffon, mesh jersey, lightweight spandex blends, and some coated nylons begin to distort above 135–140°C. Keeping press temp ≤ 130°C avoids shine, glaze, or localized shrinkage.
-
No Steam / Moisture Press Needed: Activation is purely thermal — dry heat melts the EVA layer → it wets the fibre surface → cools to form a fiber-anchoring bond. No steam injection required (though a protective Teflon/silicone sheet is recommended to prevent liner pickup).
-
Time-Dependent Bond Development: Shorter dwell (8–15 s) at correct temp reduces heat soak into the garment shell vs. longer cycles needed for some high-melt adhesives.
Thickness Selection: 0.05 mm vs. 0.10 mm vs. 0.15–0.20 mm

Application
|
Recommended Thickness
|
Rationale
|
|---|---|---|
|
Woven / printed label bonding to shell interior
|
0.05–0.08 mm
|
Thin gauge preserves label edge invisibility, minimal stiffness added
|
|
Embroidery patch backing / appliqué lamination
|
0.10–0.15 mm
|
Slightly more adhesive mass to bridge embroidery thread relief & anchor patch
|
|
Interlining / collar stay tacking (light fusible substitute)
|
0.15–0.20 mm
|
Extra film thickness compensates for surface irregularities of non-woven interlining
|
|
Foam visor / cap badge assembly
|
0.10–0.15 mm
|
Balanced bond & flexibility for curved substrates

EVA Hot Melt Film vs. TPU Hot Melt Film — Quick Comparison
-
EVA (this product): Lower activation temp, softer / more limp hand feel, lower cost, good for delicate-fabric label/patch work and domestic-wash items. Slightly less resistant to dry cleaning solvents and heavy oily sweat vs. TPU.
-
TPU Hot Melt Film: Higher activation temp (130–160°C+), greater elasticity, superior wash & oil/sweat resistance — preferred for performance-wear, sports-team badges, leathergoods. Can be too firm or require higher press temp for very heat-sensitive shells.
Typical Application Scenarios
-
Garment Brand Tag / Care Label Fusing: No needle holes, no thread ends — fuse woven labels directly to shell or facing. Low-temp press prevents show-through on thin shells.
-
Embroidered Patch Production: Apply film to back of pre-cut patch; end-user or decorator heat-presses onto garment. Flexible bond moves with spandex-blend shells.
-
Appliqué & Motif Lamination: Bond fabric motifs to base cloth before topstitching or as a no-sew alternative on accessories.
-
Interlining / Facing Tacking: Temporarily fuse interlining layers before permanent stitching, or as a permanent light-fuse on low-stress areas (collar points, cuff tabs).
-
Craft / Promotional Item Assembly: Cap badges, fabric gift tags, foam visor crowns — clean, no-residue bond.
Correct Fusing Procedure for Reliable Bond & Fabric Safety
-
Pre-Test on Scrap Fabric: Start 110°C / 12 s / medium pressure (3–4 bar / 40–50 psi). If bond lifts on cool peel, increase temp in 5°C steps — do NOT exceed 140°C for standard EVA grade.
-
Use Protective Sheet: Place silicone release paper or Teflon sheet between upper platen and film’s release liner — prevents liner adhering to press shoe.
-
Peel Timing: Warm-peel recommended for most grades (2–5 s post-press); if edges lift on textured knits allow full cool before removing carrier.
-
Storage: Keep rolls in original polybag away from direct sun & > 70% RH. If stored > 6 months in humid climate, a short ambient-air dry before use reduces risk of micro-bubbles during activation.
-
Cure Time: Full bond strength develops as adhesive cools & re-crystallises — wait 24 h before first wash or heavy flex.
Sourcing Checklist for Apparel MFrs & Embellishment Studios
-
✅ Specify thickness (0.05 / 0.08 / 0.10 / 0.15 / 0.20 mm) per application.
-
✅ Confirm roll width & length — standard 50 cm / 100 cm slit; full roll 128 m² (e.g., 1.0 m × 128 m); custom widths on request.
-
✅ Request sample swatch book (multi-thickness offcuts) for in-house press trial.
-
✅ Ask about OEM / private label packaging if reselling under your brand.
-
✅ Request TDS + MSDS + compliance certs (OEKO-TEX® Standard 100, REACH, RoHS as applicable).
