摘要: A biaxially oriented laminate film including a core layer including a blend of crystalline polylactic acid polymer and a metal salt phosphorus-containing compound nucleating agent which is biaxially oriented at low transverse direction orientation temperatures to impart a degree of cavitation around the metal salt phosphorus-containing metal such that a white opaque cavitated appearance and a lower film density and improved mechanical properties are obtained. The laminate film could further have additional layers such as a heat sealable layer disposed on one side of said 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: Films and formulations that include recycled polylactic acid resin are described. The films and formulations include, for example, 1-10 wt % of an ethylene-acrylate copolymer. The use of the ethylene-acrylate compolymer in the polylactic acid formulations allows for recycling of PLA-based films and articles with minimum degradation, as exhibited by changes in intrinsic viscosity and color properties.
