What is TPU hot melt adhesive film?

TPU hot melt adhesive film is an intelligent polymer material made by copolymerization of polyether/polyester and diisocyanate.Tpu hot melt adhesive film produced using cast or blown film processes can achieve a precisely controlled thickness of 0.01-1mm. Combined with tackifying resins, they can increase fabric peel strength to 15N/cm. They are widely used in automotive interior bonding (strong weather resistance), seamless garment lamination (washable), and seamless shoe fabric applications. Compared to EVA, they offer a lifespan exceeding 50% longer, demonstrating technological foresight in new energy and smart wearable applications (e.g., photovoltaic films and self-healing screen protectors).

Application

TPU hot melt adhesive film has good adhesion, water resistance, chemical resistance, abrasion resistance and elasticity, and can be used in a wide temperature range.

Our Story

Field of use:

Different types of hot melt adhesive films have different application fields due to their own properties and materials suitable for bonding. For example, TPU high-temperature hot-melt adhesive film is more used in underwear because it has high elasticity and is more washable; PO hot-melt adhesive film is more used in trademarks because it is cheap and washable.

Different types of hot-melt adhesive films are used for different materials. For example, for bonding XPE foam, hot-melt adhesive films made of EVA are usually used because they are all made of EVA; hot-melt adhesives such as TPU are usually used for elastic bonding fabrics. Adhesive film, because it has elasticity; PES hot melt adhesive film is usually used for bonding PET film because it has better viscosity; low-temperature TPU film is more used for bonding leather because it will not damage the leather and can provide Good adhesive adhesion. Materials to be bonded are broadly classified into several types, including cloth, leather, sponge, film, wood, plastic, rubber, sheet metal, and more.

Improved production efficiency

The TPU hot melt adhesive film uses the hot melt process, which reduces the steps required for traditional manual sewing and glue bonding. During production, only simple heating and pressing operations are needed to achieve tight bonding between fabrics, greatly improving production efficiency and reducing costs.

Improved product quality

By using TPU hot melt adhesive film, fabrics can be quickly bonded without affecting their appearance, preventing issues such as stretching and wrinkling that might occur with traditional sewing methods. This provides higher aesthetics and quality assurance for products like clothing and footwear.
