    摘要: A method of film laminating begins with a drying step for drying a plastic composition. A heating step melts the plastic composition to form a gelatinized combination. An extruding step extrudes the gelatinized combination, and in a blow molding step air is blown into the gelatinized combination to provide a film composition. In a flattening step, the film composition is flattened to form a film, and then in a first laminating step, a heterogeneous material is laminated onto a surface of the film using an adhesive to form a composite. Finally, in a cutting step, the composite is cut into suitable lengths.

    摘要: A method of manufacturing a film includes forming a blend containing a renewable content starch, a renewable content mineral, and polyethylene, operating a mass flow hopper to maintain a consistent mass flow rate of the blend to a feed throat of an extruder, and operating the extruder with a screw speed and melt temperature based on the amount by weight of the starch and mineral within the blend. The melt is passed through a screen pack with a mesh rating based on the amount by weight of the starch and mineral within the blend, is passed through a die, and is cooled into a film. The film is nipped to a gauge such that the film can be formed into a bag.
