A laminated packaging material suitable for use in packaging products in pouch form, comprises (A) as an outer surface, a substrate of paper or film which may be printed and/or primed; (B) an adhesive layer, (C) a metallic foil, preferably aluminum, (D) an optional primer, (E) a barrier coextruded layer comprised of two or three-layer combinations of ethylene-methyl acrylate copolymer and polyester, and (F) an optional polyolefin film layer. Pouches prepared from this packaging material provide a chemical barrier between the foil and the product contained therein and are especially useful where the foil needs to be protected from the product.
