Multilayer sheets and films composed of polypropylene and cyclic olefin copolymer

摘要

Multilayer sheets and films are provided that include a layer of a polyolefin material and a layer of a thermoplastic polymer material. More particularly, multilayered structures are provided in which a layer of a polypropylene is attached to a layer of a cyclic olefin copolymer material. The adhesive material used to adhere said layers achieves a significantly improved interlayer bond strength as compared to the art.
