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.
