Abstract
Gelatine granules obtained by plasticizing conventional gelatine consist of solid gelatine particles with a water content of from 1 to 12% by weight, with a particle size of from 0.1 to 10 mm, with an entrapped air content of less than 1% by volume and with a melt flow index greater than 1 g/10 min at 110 degrees C. The granules are thermoplastic and solid or hollow molded articles can be made from them like from conventional plastics by extrusion, injection molding, blow molding and the like.
