Claim Text:
1. A film thermally adhered to a rigid structure, the film comprising: a polymer layer, wherein the polymer layer is a material selected from the group consisting of polyolefins and polyamides and the polymer layer has a thickness of about 0.0008 to about 0.005 inches; a second layer adjacent to the rigid structure, wherein the second layer is a material selected from a group consisting of polylactide acid, aliphatic-aromatic polyesters, poly(3-hydroxyalkanoate) (PHA), cellulose and starch based polymers and has a thickness of about 0.0008 to about 0.006 inches; and an adhesive layer joining the polymer layer to the second layer, wherein the joined polymer layer and second layer have a bond strength greater than 800 grams per inch of pull, the second layer is thermally adhered to the rigid structure and the rigid structure comprises a material selected from the group consisting of polylactide acid, aliphatic-aromatic polyesters, poly(3-hydroxyalkanoate) (PHA), cellulose and starch based polymers.
