Abstract: An improved process for making synthetic paper/film from a blend of polystyrene and polyethylene resins wherein titanium dioxide is employed as the sole inorganic filler and the film is given an oxidizing post-treatment, such as corona discharge or surface sulfonation. The film so-prepared has improved adhesion to photographic gel emulsions.

Abstract: A spirally wound container for leavened dough and other products which is opened by side rupture. The container comprises a fiber board body having multiple thermoplastic film plies. An inner transparent ply of film adheres to the surface of the fiber board spirally wound can body and is rupturable therewith. An outer ply of film forms a label cover for the container and is strippable prior to opening of the container. After the label ply is stripped from the container, the transparent inner ply permits reading of graphics printed on the fiber body of the can. The inner film ply strengthens the body ply and acts as a moisture barrier.
