PCT No. PCT/EP93/02239 Sec. 371 Date Oct. 24, 1994 Sec. 102(e) Date Oct. 24, 1994 PCT Filed Aug. 20, 1993 PCT Pub. No. WO94/04201 PCT Pub. Date Mar. 3, 1994.A foil-shaped wound covering material based on collagen fibers, its laminates, and a process for preparing the same are disclosed. The wound covering material essentially consists of insoluble, partially modified collagen characterized by the following parameters: 0.18 to 0.40 mmol/g amidated nitrogen; less than 5 mu mol/g glucosamine and less than 5 mu mol g galactosamine; shrinking temperature from 45 DEG to 60 DEG C.; isoelectric point from 4.3 to 60.0.
