Multi-layered films with visually-distinct regions and methods of making the same

摘要

Multi-layered 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 multi-layered 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 visually distinct stretched regions include incrementally stretching a plurality of film layers, at least one of which includes a thermoplastic material and a voiding agent.
