Abstract

Multiple layer films and containers. The films have a first layer of either nylon 6,6 or a combination of nylon 6,6 with nylon 6 wherein the melting point temperature of the combination is greater than the melting point temperature of the corresponding nylon 6. A second layer is comprised of linear low density polyethylene, and 0% to 40% low density polyethylene. A third adhesive layer is disposed between the first and second layers. The containers are susceptible of being sealed with included gas at low pressure, and subsequently boiled in water without rupture of the seals. The film is preferably coextruded from tubular die, thereby setting forth a new method for forming a mulitple layer film comprising a combination of linear low density polyethylene, optionally with up to 40% low density polyethylene, and nylon 6,6, optionally combined with nylon 6 in a composition having a melting point temperature greater than that of the corresponding nylon 6.
