Abstract

The invention relates to a disposable surgical drape film. The disposable surgical drape film is prepared from a material A and a material B by plasticizing co-extrusion, wherein the material A comprises components in parts by weight as follows: 100 parts of metallocene polyethylene resin and 0-5 parts of blue masterbatch; the material B comprises components in parts by weight as follows: 40-60 parts of SEBS resin, 60-40 parts of POE (polyolefin elastomer) elastic resin and 1-5 parts of blue masterbatch. Meanwhile, the invention provides a preparation method of the disposable surgical drape film. The surgical drape film has the advantages of low production cost, elasticity, good comfort, excellent barrier property and the like.

Description

technical field [0001] The invention relates to a disposable surgical drapery and a preparation method thereof. Background technique [0002] Surgical drapes are surgical drapes specially used to perform surgical operations on specific parts of patients. The surgical drapes have holes for specific surgical locations. Surgeons can operate on the preset holes. [0003] The early surgical drapes were mainly made of cotton cloth or PE film. Due to the limitation of the physical properties of cotton cloth or PE film itself, only simple drape can be realized. However, the complexity of modern surgical operations requires surgical drapes to be used with various materials according to different functional needs. Traditional textiles have been difficult to adapt to modern surgical operations. Contents of the invention [0004] The purpose of the present invention is to provide a disposable surgical drapery with low production cost, good elasticity and comfort, and excellent barrie...
