  • Polymeric films and bags
    Patent number: 10293980
    Abstract: The present invention is directed to a method of incrementally stretching polymeric film formed from a blown film extrusion process. The present invention is further directed to a polymeric bag formed from an incrementally stretched polymeric film. The incremental stretching is performed on a collapsed polymeric bubble via a pair of intermeshing rollers. The incrementally stretched polymeric film may be stretched only along a portion of its width. The polymeric bag may be a drawstring trash bag with an extended hem where only the extended hem of the bag or the body of the bag comprises incrementally stretched polymeric film.

  • Polymeric bags
    Patent number: 10138054
    Abstract: The present invention relates to improvements for the manufacturing of a wave-cut bag, more specifically a wave-cut bag with improved tie-flaps. Disclosed is a process for intermittently incrementally stretching and imparting a rib-like pattern to a collapsed tube of a blown film extrusion process. The incrementally stretched collapsed tube is particularly well suited for constructing wave-cut trash bags with a rib pattern on the tie-flaps of the trash bags. Further disclosed is a wave-cut trash bag with a rib pattern on its tie-flaps and surrounding area. The process is further well suited for constructing wave-cut trash bags with a rib pattern on a central body of the trash bags.
