摘要:
A biaxially oriented laminate film including a core layer including a blend of crystalline polylactic acid polymer and an inorganic antiblock particle which is biaxially oriented at low transverse direction orientation temperatures to impart a degree of cavitation around the particles such that a matte or opaque appearance is obtained. The laminate film may further have additional layers such as a heat sealable layer disposed on one side of the core layer including an amorphous polylactic acid resin and/or a polylactic acid resin-containing layer disposed on the side of the core layer opposite the heat sealable layer, a metal layer, or combinations thereof.
摘要:
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.
