Abstract
A structure which is useful for making containers for dentifrices, such as tubes, is comprised of a structure where the layer which contacts the dentifrice consists of a blend of polybutylene terephthalate and polyethylene. Other layers can consist of adhesives, paper, foils, other polymers and the like depending on the properties desired. A polybutylene terephthalate-polyethylene layer has been found to have a low degree of absorption of flavorant.
