Description

Technical Field

[0001] The utility model relates to the technical field of foam adhesive backing, in particular to a soft multi-layer foam adhesive backing. Background Art

[0002] Foam adhesive is a composite material with a foam material and an adhesive layer attached to the back. Foam is a soft and elastic material, usually made of polyurethane, polyester or polyether. The adhesive layer is a layer of glue or adhesive attached to the back of the foam, which can make the foam firmly bonded with other materials or surfaces. Foam adhesive is usually used in various products, such as shoes, clothing, furniture, car seats, etc.

[0003] The existing foam adhesive on the market has a single cushioning structure and limited overall cushioning performance. At the same time, since the foam adhesive structure has many layers and the adhesion between the layers is insufficient, it will separate over a long period of time.
