BIAXIALLY ORIENTED METALLIZED POLYLACTIC ACID FILM WITH HIGH METAL ADHESION AND HIGH BARRIER PROPERTIES

摘要

Metallized multi-layer biaxially oriented polylactic acid base polymer (BOPLA) films that exhibits improved barrier properties and metal adhesion. The films include a core layer including crystalline polylactic acid base polymer, a first skin layer consisting essentially of amorphous polylactic acid base polymer, and a metal layer on the first skin layer. The films may include a second skin layer consisting essentially of amorphous polylactic acid base polymer.
