Hot melt adhesive film, also known as hot melt double-sided tape or hot melt iron-on adhesive, is a type of adhesive material that is capable of bonding two different materials well. It is widely used in many fields, including shoes, clothing, furniture, insoles, cosmetic puffs, bags, electronic products, automotive supplies, and more. When used in shoe surface composite, hot melt adhesive film can act as an adhesive, firmly bonding different parts of the shoe surface together to ensure that the structure of the shoe is strong and not easily separated or damaged. In addition, hot melt adhesive film can also improve the wear resistance and durability of shoes, especially in the frequently worn outsole and toe areas, which can extend the service life of shoes.
