Abstract

An improved non-reinforced cellulose film is disclosed. The film is useful as a sausage casing. When exposed to water the casing shrinks in the transverse or circumferential direction, so that the sausages look plump and crease-free and the casing can be peeled easily from the enclosed sausage meat. The film is made by moistening a non-reinforced cellulose film, drawing the film in the transverse direction, and drying the film in the stretched state.
