A multilayer plastic film comprising polyethylene outer layers with inner layers of additional polyethylene adjacent to tie layers of adhesive bonded to a blended polyamide and polyvinyl alcohol core. This structure results in excellent oxygen and water barrier properties. The film can be coextruded in a blown film process that results in a durable barrier film without the sacrifice of optical properties. Film applications include, but are not limited to, food packaging such as bags, liners, pouches, shrink bags, and chubs. In certain embodiments, the film can also be used for food packaging, including packaging of meat, cheese, milk, condiments, salad dressings, or any other oxygen sensitive products.

High oxygen and water barrier multilayer film

A novel smokable thermoplastic film, smokable by both liquid smoke and gaseous smoke, that may be produced as a film or a tube, as in a food casing. This newly disclosed film is a blend of a polyamide base, an amorphous polyvinyl alcohol and, optionally, an antiblocking agent.
