The present invention relates to the composition and preparation of composite films which exhibit low oxygen and flavor/aroma transmission rates. The film comprises a silane resin coated on a plastic substrate. The silane resin is formed from the mixture of a silane solution, an acrylate, a solvent, and optionally, either an additive, water or both. This invention teaches that a variety of silane solutions and acrylates may be mixed with different solvents to achieve the desired oxygen and flavor/aroma barrier characteristics.
