COLLAPSIBLE LAMINATED TUBE FOR TOOTHPASTE

摘要

A laminated structure which is useful for making tubes for dentifrice tubes is comprised of a structure where the laminate layer which contacts the dentifrice consists of a blend of polybutylene terephthalate and polyethylene. The other layers can consist of adhesives, paper, foils and the like. A polybutylene terephthalate-polyethylene layer has been found to have a low degree of absorption of flavourant.
