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