ABSTRACT:
A retortable pouch is made without the use of metal foil. The improved heat sealable structure has an inner heat seal layer of linear low density polyethylene. The second, or adjacent layer is a blend of 20% to 80% linear low density polyethylene and 80% to 20% propylene ethylene copolymer. Optional third, fourth and fifth layers are propylene ethylene copolymer. A sixth layer is anhydride modified polypropylene. A seventh layer is nylon, the eighth layer is ethylene vinyl alcohol copolymer and the ninth layer is nylon. The entire multiple layer structure is firmly adhered together so that the layers mutually support each other in the unitary package.
