POLYMERIC BAGS AND METHOD OF FORMING POLYMERIC BAGS

摘要

The present invention relates to improvements for the manufacturing of a wave-cut bag of polymeric film, more specifically a wave-cut bag with a body having improved shock, tear and puncture resistance. The polymeric film has an embossed pattern of a plurality of embossed regions that are comprised of a plurality of parallel, linear embosses. Further disclosed is a process for intermittently applying the embossed pattern to a collapsed tube of a blown film extrusion process. The collapsed tube with the intermittently applied embossed pattern is particularly well suited for constructing wave-cut trash bags with the embossed pattern applied to a central body of the wave-cut bags.

主权项

1. A method of forming a bag of polymeric film, the method comprising:
forming a collapsed tube of polymeric film, the collapsed tube having a machine direction, a pair of intermeshing rollers intermittently engaging and disengaging the collapsed tube to form a plurality of embossed sections and a plurality of unembossed sections,
each embossed section comprising a plurality of embossed regions, each embossed region separated from adjacent embossed regions by an unembossed arrangement, and forming the collapsed tube into a plurality of bags, each bag comprising at least a fraction of one of the plurality of embossed sections.
