  • Method of manufacturing foamed thermoplastic films and trash bags
    Patent number: 8865037
    Abstract: A method of manufacturing foamed thermoplastic films and trash bags wherein a foaming agent is added to a base thermoplastic resin. The resultant foaming agent/base resin mixture is extruded to form a single-ply foamed thermoplastic film. The film may be formed into bag, such as a trash bag.
    Type: Grant
