Films having improved characteristics and methods for their preparation and use

摘要

Gelatin film compositions are useful for immobilization over tissue, usually by the application of energy to the films. Exemplary films comprise cross-linked and non-cross-linked granular and non-granular gelatin sheets, typically including a plasticizer. The gelatin films are dry, thin, and preferably meet certain pliability, elasticity, melting temperature, and other criteria. Methods are described for producing these films from collagen. Methods are further described for applying these films to tissue.
