Metalizable Oriented Polypropylene Films With A Functionalized Tie Layer Material

摘要

Described is a multi-layered film comprising a core layer comprising polypropylene; a metalizable skin layer such as a treated HDPE or PETG; and a first tie layer comprising a functionalized polypropylene such as an acid-grafted isotactic polypropylene between the core layer and metalizable skin layer; wherein the metalizable skin layer comprises a polymer having a surface energy (ASTM D2578) of at least 30 dynes/cm, a Young's Modulus (ASTM D790) of at least 1500 MPa, and a melting point (ASTM D3418) of at least 130� C.; and wherein the film as measured on the metalizable skin side has a Haze of less than 1000 Haze Units, and a Gloss of greater than 300 Gloss Units.
