摘要: A method for packaging plastic material using a film to surround the material, and more particularly copolyester, resulting package formed thereby. The is preferably coextrusion process an amorphous or semi-crystalline copolyester having low glass transition temperature by extruding it through die orifice, coextruding polymeric high copolyester. coated may then be into individual packaged units finite size shape.
