Abstract:
A multilayer film including a first layer including a polylactic acid polymer, a second layer of a metal primer, deposited upon one surface of the first polylactic acid polymer layer, and a third metal layer deposited on the second metal primer layer. This metal-primed and metallized polylactic acid film exhibits improved moisture barrier properties versus a non-metal-primed and metallized polylactic acid film and can be used as part of a lamination structure for food packaging applications.
