A laminated packaging material suitable for use in flexible containers for potato chips, cookies, and the like comprises (A) as an outer layer, a transparent sheet of nylon coated on its inner surface with an acrylic latex, (B) a coextruded laminate of pigmented polyethylene and ethylene acrylic acid copolymer, (C) a metallic foil, preferably aluminum, and (D) a heat-sealable polyolefin as the inner layer. This packaging material not only prints well but also can be formed by co-extrusion lamination to achieve excellent lamination bond strength.
