THERMOPLASTIC FILMS WITH VISUALLY-DISTINCT STRETCHED REGIONS AND METHODS FOR MAKING THE SAME

摘要

Thermoplastic films include intermittent stretched regions that are visually distinct from un-stretched regions. The stretched regions can be white, opaque, and non porous. The thermoplastic films with visually-distinct stretched regions can be formed into bags for use as trash can liners or food storage. Additionally, methods of stretching thermoplastic films to create non-porous, white, and opaque stretched regions include incrementally stretching a film of a thermoplastic material and a voiding agent.

主权项

1. An incrementally-stretched film with visually-distinct stretched regions, comprising:
a film layer of linear low-density polyethylene including a first plurality of un-stretched regions and a second plurality of stretched regions intermittently dispersed about the first plurality of un-stretched regions; wherein the stretched regions are:
non-porous, andmore opaque than the un-stretched regions.
