BIAXIALLY ORIENTED POLYLACTIC ACID FILM WITH IMPROVED MOISTURE BARRIER |
摘要 |
A biaxially oriented multilayer film comprising a skin layer of polyhydroxyalkanoate, a core layer of polylactic acid polymer and a sealant layer with a metal deposited upon one surface of the skin layer of polyhydroxyalkanoate polymer. This metallized, polyhydroxyalkanoate-coextruded polylactic acid film exhibits improved moisture barrier property versus a metallized, non-polyhydroxyalkanoate-coextruded polylactic acid film.
