METALLIZED POLYETHYLENE FILM WITH IMPROVED METAL ADHESION.

摘要

A multi-layer structure comprising: (a) a skin layer comprising at least 50% by weight of an ethylene/α-olefin interpolymer composition (LLDPE) having a Comonomer Distribution Constant (CDC) in the range of from 45 to 400, and wherein the skin layer does not contain any migratory additive; (b) a metal layer disposed on the skin layer to form a metalized film; and (c) at least one substrate layer laminated onto the metallized film; wherein the ethylene/α-olefin interpolymer composition comprises (i) less than or equal to 100 percent by weight of the units derived from ethylene; and (ii) less than 30 percent by weight of units derived from one or more α-olefin comonomers is provided.
