More Information
Summary:Disclosed is a multilayer structure that comprises a heat sealable layer comprising amorphous polyethylene terephthalate with a melting point greater than 200° C., a pressure sensitive adhesive and at least one tie layer encapsulating the pressure sensitive adhesive. The structure can be coextruded without degrading the pressure sensitive adhesive. Also disclosed is a reclosable package comprising the structure and methods to make such structures.
