Coextruded, Heat-Sealable and Peelable Polyester Film |
摘要 |
The invention relates to a coextruded, peelable, and biaxially oriented polyester film with a base layer (B) and with at least one outer layer (A) applied to this base layer (B). The outer layer (A) is heat-sealable and features peelability with respect to nonpolar substrates, such as polystyrene ("PS") and polypropylene ("PP"). The heat-sealable and peelable outer layer (A) includes a copolymer formed from ethylene and an acrylate. The invention further relates to a process for the production of the film and to packaging formed from the film.
