product details
Solamni leather Introducing Our EVA composite nonwoven insole board is a laminated structural component consisting of a cellulose fiber nonwoven base bonded to an EVA foam layer via heat compression. The nonwoven layer provides dimensional stability and stitch-tear resistance, while the closed-cell EVA layer (density 0.91–0.93 g/cm³) delivers shock absorption and moisture resistance. Solamni supplies this composite in custom thicknesses (0.4mm–3.0mm EVA layer) and sheet sizes (1.0m × 1.5m standard), with REACH compliance and SATRA/ISO test documentation for footwear OEMs worldwide.

Solamni manufactures TPU lamination film via precision calender extrusion lines with closed-loop thickness control. Each production batch undergoes the following validation protocols:
Dimensional & Visual Inspection:
Thickness is measured at 10 points per linear meter using a digital micrometer (±0.01mm accuracy). Batch acceptance requires ≥98% of readings within specified tolerance.
Film surface is inspected for pinholes, fisheyes, and contamination under transmitted light. Width is verified with electronic edge-guide sensors.
Mechanical & Adhesion Performance:
Peel Strength: Laminated specimens (TPU film bonded to polyester/cotton fabric) are tested on a UTM at 100mm/min per ISO 2411. Minimum acceptance: 8 N/mm. Bonding parameters: 120°C–140°C, 3kg pressure, 15 seconds dwell time.
Tensile & Elongation: Film samples are pulled at 200mm/min per ASTM D412. Acceptance: tensile strength ≥30MPa, elongation ≥300%.
Flex Fatigue: Laminated composites undergo 50,000 dynamic flex cycles on a Bally flexometer at -20°C. Zero delamination or cracking required.
Waterproof & Breathability Validation:
Hydrostatic Head: Film samples (0.012–0.025mm) are tested per ISO 811. Acceptance: >10,000 mmH₂O.
MVTR: Measured per ASTM D6701. Acceptance: ≥650 g/m²/day.
Environmental & Chemical Compliance:
All TPU resins are screened for phthalates (≤0.1% per REACH Annex XVII), heavy metals (Pb ≤90ppm, Cd ≤10ppm), and formaldehyde (≤75mg/kg).
Solvent-free production ensures zero VOC emissions. OEKO-TEX Standard 100 certification (skin-contact safety) available upon request.
Factory Traceability:
Each master roll receives a unique batch number linked to extrusion line ID, resin batch certificate, thickness profile log, and QC test results. Retained samples (A4-size cutouts) archived for 36 months. Digital Certificate of Analysis issued within 48 hours of production.
Industrial Application Scenarios
Footwear Manufacturing (Primary)
Shoe upper lamination: Bonds mesh, knit, leather, and PU leather layers into seamless, stitch-free uppers. Film thickness 0.05–0.20mm for lightweight athletic footwear.
Seamless shoe construction: Replaces traditional sewing with heat-activated bonding, reducing labor costs and eliminating needle-hole weakness.
Waterproof bootie construction: Hydrophilic TPU membrane (MVTR ≥650 g/m²/day) laminated between outer fabric and lining for waterproof-breathable footwear.
Reinforcement & support: Internal heel counters and toe puffs using 0.3–1.0mm TPU film for structural integrity.
Decorative applications: High-frequency welded 3D logos, brand labels, and lace reinforcements.
Apparel & Garment Manufacturing (Secondary)
Outerwear & sports apparel: Waterproof-breathable membrane lamination for rain jackets, ski wear, and running gear.
Seamless garment construction: Bonding of fabric panels without stitching for athletic wear and shapewear.
Heat transfer & embellishment: TPU film as carrier for heat-applied logos, reflective trim, and decorative patches.
Other Applications
Bags & luggage: Lamination of nylon/canvas for water-resistant backpacks and travel bags.
Automotive interiors: Fabric-to-foam bonding for seat covers and headliners.
Medical textiles: Skin-contact breathable films for wound care and wearable devices.

Frequently Asked Questions (FAQ)
What is the minimum activation temperature for your TPU lamination film, and how does it protect heat-sensitive shoe upper materials like fly-knit?
Low-temperature grade activates at 65°C–95°C. This prevents shrinkage, discoloration, or melting of nylon/polyester knits. Standard activation: 120°C–140°C. We recommend small-scale trials to establish your specific process window.
Can your TPU film withstand repeated washing and hydrolysis degradation in outdoor footwear?
Yes. Polyether-based TPU grades offer ≥5 years hydrolysis resistance (70°C/95% RH Jungle Test). Peel strength retention after 50 wash cycles exceeds 85%. Saltwater and sweat resistance validated per ISO 1419.
What is the MOQ and lead time for a custom-colored TPU lamination film at 0.15mm thickness for a 5,000-pair shoe production run?
Standard MOQ: 500 meters per color. Custom color matching (Pantone): 7–10 business days. Bulk production: 12–18 business days after sample approval. Sample rolls (50 meters) available for process validation.
