Abstract
A process for making gelatine films, in particular sheet gelatine, from powdered gelatine includes the following steps: The powdered gelatine with the addition of water is plasticized by the application of shearing forces at an elevated pressure and an elevated temperature, the plasticized mass is pressed in the form of a film through a slotted die, the film is drawn off the slotted die under tension and the taut film is dried.

Process for making sheet gelatine from powdered gelatine, wherein the powdered gelatine with the addition of 5 to 40% by weight of water in relation to the total mass is plasticized by the application of shearing forces at an elevated pressure of 5 to 250 bar and an elevated temperature of 40.degree. to 200.degree. C., the plasticized mass is pressed in the form of a film through a slotted die, the film is drawn off the slotted die under tension to produce a taut film, the taut film is dried to produce a finished film and the film is cut into single sheets of sheet gelatine.
