Multiple layer polymeric films and flexible containers made therefrom. |
摘要 |
<p>Polymer blends are used in making multiple layer films suitable e.g. for packaging. In some layers of the films an elastomer or ethylene-based copolymer is blended with polypropylene, and in some layers, with polyethylene; typical films have two to five layers, in multilayer films, at least one layer (14) is a blend of polyethylene, preferably high density polyethylene, with elastomer and/or ethylene-based copolymers, and another layer (12) is polypropylene blended with elastomers and/or ethylene-based copolymers. A two layer film has two layers, one layer (12) having polypropylene and polyethylene, preferably high density polyethylene blended together. …<??>Such films can be used to fabricate packaging bags or pouches by forming heat seals (18) between confronting pieces of film; such bags or pouches are retort sterilisable and suit the packaging of medical fluids.</p> |
