Patent

CA 2361084

A retortable pouch for use with food products is disclosed. The retortable pouch includes at least one sheet made from a three-layer or four-layer laminate material. The laminate material includes an outer polyethylene terephthalate layer, an optional nylon second layer, a metal foil third layer, and a polypropylene inner layer. A solventless adhesive is used to bond the layers together. The retortable pouch is formed by heat sealing the edges one of more sheets of the laminate such that the polypropylene layers face inward and are welded together. The pouch and its contents can then be pasteurized by heat-treatment without degradation of the laminate or the heat seal.
