Abstract

A low-melting adhesive film may include a first adhesive layer made of a material comprising thermoplastic polyurethane, a second adhesive layer made of a material comprising aromatic-based hot-melt thermoplastic polyurethane capable of being applied to low temperature adhesion at a temperature of 60° C. or higher, and a polyethylene (PE)-based protective film layer. The low-melting adhesive film may be used to adhere a carpet fabric to a sound absorbing material and thus produce an integrated sound absorbing and proofing composite carpet.
