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 .
