Medical waterproof wound film and its making process

Abstract

The present invention provides one kind of medical waterproof wound film and its making process. The medical waterproof wound film is one composite film including substrate layer, optionally permeating layer, adhesive layer and non-sticking layer superposed successively. The making process includes the steps of: painting the copolymer of acrylate and esteramide onto the non-sticking layer of strippable paper to form the adhesive layer, painting polyesteramide to the polyethylene terephthalate substrate to form optionally permeating layer, compounding the optionally permeating layer and the adhesive layer, etc. The medical waterproof wound film is waterproof, oxygen permeating to inhibit the growth of anaerobe and reduce infection, vapor permeable to maintain certain humidity and favorable to the growth of granulation tissue, and can promote the healing of wound.
