ABSTRACT:
A multiple layer polymeric-based sheet structure is suitable for forming dispensing tubes. The abuse resistance of the tube is improved by incorporating in the sheet structure a layer of oriented polypropylene. A layer of linear low density polyethylene provides for heat sealing and has substantially improved stress crack resistance and resistance to generation of polydust.
