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.
