  • Take-off unit
    Patent number: 7279125
    Abstract: A withdrawal device for blow-molded film has an air turning bar with an air cushioned surface for transporting the film, and the bar surface includes at least in part a sintered material. The sintered material portion of the bar surface provides a region of increased friction for compressed air flow, thus more effectively guiding the withdrawn film in a flat and even form.

  • High strength plastic film and process for its production
    Patent number: 6359074
    Abstract: A high strength, stretched, polyethylene plastic film is described. To obtain better stretchability, the film includes an effective amount of an acetate polymer. Typically, the polyethylene film contains up to 10% of acetate polymer. A suitable acetate polymer is polyvinyl acetate. A process for the production of a high strength polyethylene plastic film including an acetate polymer is also described.
