To reduce the amount of staining that occurs during the in-package retort processing of food products, a packaging film is used including a white multilayer film, the white multilayer film having a sealing region on the exposed surface of the packaging film, a white region containing white pigment and a blocking region located between the white region and the sealing region, where the combined thickness of the sealing region and the blocking region is at least 70% of the thickness of the white multilayer film.

Stain resistant packaging film for retort applications

The present invention relates to improved self-adhesive labels which are suitable far use in adhering to wet surfaces or wet irregularly shaped surfaces such as that found on fruits and vegetables. The self-adhesive label is made of a water absorbent backing layer having opposing sides and a rubber-based pressure sensitive adhesive applied on one side of the backing layer. The adhesive is discontinuously coated as a pattern onto the backing layer to provide areas of the adhesive interspersed with areas which are free of adhesive.
