A multi-perforated collagen film is provided on rolls or in the form of sheets for use as a food wrapping. The perforations and made by laser of substantially circular shape with an average ellipticity of less than 0.17 and the holes are spaced with respect to their nearest neighbors by 3 to 14 mm, thus allowing the escape of air or steam trapped between the film and the food wrapped in the film. The film still has sufficient mechanical strength and extensibility to be able to stand the food processing steps in the manufacture of cooked ham or in comparable operations under industrial conditions.
