Breathable Composite
Bonding Solutions
Solve the industry dilemma of balancing strong bonding with breathable comfort. Our hot melt adhesive web technology achieves flat lamination without blocking microporous structures, ensuring long-term breathability, moisture permeability, and a soft hand feel.
Redefining Breathability in Flexible Composites
Breathability is a critical performance metric for textiles, footwear, upholstery, and medical supplies. We eliminate the traditional trade-off between durable bonding and optimal comfort.
Advanced Mesh Film Technology for Uncompromised Airflow
Traditional solid adhesives often cause poor ventilation, trapped moisture, blistering, and stiffness. Our breathable hot-melt adhesive mesh film perfectly resolves these industry pain points. By maintaining the substrate's original micro-porous structure, it ensures flawless lamination without sacrificing comfort.
- Long-lasting breathability & moisture permeability preventing stuffiness and internal condensation
- Exceptional bonding strength that eliminates the risk of surface blistering and delamination
- Maintains natural drape and soft hand-feel, preserving the original flexibility of the materials
- Versatile multi-industry application spanning apparel, footwear, bags, furniture, and medical supplies

Engineered for high-strength sealed bonding, they are the definitive choice for applications where moisture vapor transmission and breathability must be strictly prevented.
| Product Name | Breathability Level | Core Characteristics | Suitable Applications |
|---|---|---|---|
|
TPU Hot Melt Adhesive Film
|
Very low (micro-permeable) | Dense non-porous material, only minimal molecular moisture transmission, no air convection, excellent waterproof. | Waterproof sealing, flex-resistant, high-strength composites; not for breathable soft fabrics. |
|
TPE Hot Melt Adhesive Film
|
Non-breathable | Solid dense structure, completely blocks substrate micropores, no air passage. | Soft sealing, anti-vibration bonding, waterproof composites – no breathability requirement. |
|
PA Hot Melt Adhesive Film
|
Non-breathable | Full-coverage solid layer, good sealing; large-area lamination can trap air and cause stuffiness. | General sealing composites, furniture bonding – for breathable applications, replace with PA mesh. |
|
PES Hot Melt Adhesive Film
|
Completely non-breathable | Extremely dense and stable adhesive layer; best sealing, waterproof, and weather resistance. | Outdoor waterproof, moisture-proof, anti-corrosion high-durability structural composites – strictly not for breathable products. |
|
EVA Hot Melt Adhesive Film
|
Non-breathable | Dense texture, strong barrier property, completely blocks air flow; cost-effective sealing. | General sealing composites, packaging bonding, rigid-soft composites with no breathability requirement. |
|
PO/EAA Hot Melt Adhesive Film
