Abstract: The present invention is a substantially non-adhesive elastic gelatin matrix. The matrix is both non-adhesive to wounds, tissues and organs and is also elastic such that it is flexible. The matrix is a lyophilized mixture of protein(s), polymer(s), cross-linking agent(s) and optional plasticizer(s). The invention also provides methods for making the non-adhesive elastic gelatin matrix.
