Car seats usually involve the composite of materials such as leather, leather, fabric, sponge, etc., which has relatively high requirements for the bonding strength of the materials after composite materials. The hot melt adhesive film materials often involved in car seat material composites are EVA hot melt adhesive film and TPU hot melt adhesive film. In addition, car seats also have certain requirements for cost breathability and durability. Since it involves the automotive industry, VOCs testing and monitoring is strict. Adhesive products used to compound various materials cannot evaporate harmful substances, and hot-melt adhesive film products can meet this requirement to a large extent.
