Abstract
The invention discloses a multiple layer film useful in packaging, and the packages made therefrom. A first layer of the film is a material containing an ester group, a polycarbonate or a polyether block amide copolymer. A second layer of the film is a sealant, preferably polypropylene polymer blended with an elastomeric styrene ethylene butylene styrene copolymer. A third functionally adhesive layer is between the first and second layers. The composition of the third adhesive layer is typically either a polypropylene modified with a carboxy group such as an organic acid or anhydride or a styrene ethylene butylene styrene copolymer.
