Multilayer metallized film having enhanced barrier and metal adhesion characteristics

摘要

Polyolefin films having excellent barrier and metal adhesion characteristics and methods for producing the same are provided. The polyolefin film structures include a polyolefin core layer having a first and second side, a heat sealable layer adjacent to the first side of the core layer and substantially coextensive therewith, and a high barrier layer adjacent to the second side of the core layer and substantially coextensive therewith. The high barrier layer includes a blend of ethylene vinyl alcohol copolymer and nylon. Preferred embodiments of the present invention also provide for a metallized skin layer adjacent to the high barrier layer and substantially coextensive therewith.
