Abstract
A plastic laminate sheet for making collapsible dispensing container comprises an outer layer of filled-plastic made of polypropylene or a blend of polypropylene, and high density polyethylene, and a filler, preferably calcium carbonate, incorporated therein. The outer filled-plastic layer is coextensively bonded to an inner layer of high density polyethylene to form the laminate sheet. An intermediate layer of an oxygen barrier plastic may be interposed in the laminate sheet in order to impart oxygen impermeability thereto.
