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.
