Abstract
A generally transparent flexible packaging structure having an anti-transfer layer which, in a closed and sealed package, is at or close to an interior surface of the package. A contained food product in the package has a tendency to deposit a food product component on the interior surface of the packaging material and to thereby have a visually obscuring affect on transparency of the packaging structure. Anti-transfer material in the anti-transfer layer migrates to the interior surface of the package and interacts with the visually-obscuring component of the contained food product, thereby to attenuate or eliminate the visually obscuring effect of such component. Preferred primary polymer in the anti-transfer layer is EVA. Preferred anti-transfer materials include fatty acid esters and other amines and derivatives. The invention includes certain aspects of multiple layer packaging structures, closed and sealed packages, and methods of packaging food product.
