Film laminate

A multilayered composite laminate structure, comprising:

• a substrate layer having first and second opposing surfaces;
• a first layer of a film that comprises a material that is environmentally degradable and annually renewable and is independent of a petroleum-based product;
• a first adherent layer that binds the first film layer to the first surface of the substrate;
• a second layer of a film that comprises a material that is environmentally degradable and annually renewable and is independent of a petroleum-based product;
• and
• a second adherent layer that binds the second film layer to the second surface of the substrate.

A composite laminate structure, comprising:

• a first layer of a film that comprises a material that is environmentally degradable and annually renewable and is independent of a petroleum-based product, where the material of the first layer comprises a polyactide polymer made from vegetable matter;
• a substrate that comprises paper or recycled paper, woven fabrics, non-woven fabrics, non-metallic films, or metallic foils;
• and
• an adherent layer that binds the first layer and the substrate together, where the adherent layer comprises polymeric extrudates, water-based adhesives, hot melt, solvent based adhesives or solvent-less adhesives,
• where one or both surfaces of the first layer are coated with a liquid polymer, nano-particle dispersions, a metallic deposition or a silicone oxide deposition such that a gas permeability of the first layer is reduced.
