Abstract:
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.
