Problems solved by technology

[0002] The single-color film used in the operating room for disposable surgical drapes does not distinguish between the front and back sides, and it is difficult to distinguish the disinfection side before the operation, which brings hidden dangers to the health of patients
In order to distinguish the positive and negative sides, the current method is mainly to print or compound a layer of glued composite film of other colors on one side of the film. The ink used in the printing process of printing the film on one side will cause peculiar smell; the glued composite film not only needs to produce two different colors. film, but also increase the adhesive, resulting in increased film thickness, which increases the process and cost to varying degrees

Abstract

The invention relates to a dual-color polyethylene film for operating room disposable drapes. High-pressure low-density polyethylene resin, metallocene linear polyethylene resin, color master batch and antifoaming agents are extruded out from two screw extruders to be plastified, through a T-shaped flat seam mold head, extrusion is carried out, and a sheet is formed; an embossing steel roller anda rubber roller carry out pressing shaping, and through traction and ear cutting, the sheet can be used for the operating room disposable drapes. Ink printing or adhesive is not used, the aim of distinguishing the front face and the back face is achieved, in the dual-color film made through the ink printing process, equipment needs to be added, and solvent ink is used; the dual-color film made through bonding of the adhesive needs to produce two different films, the bonding agent is used for bonding, and the cost of bonding equipment is high; and compared with the above two processes, the ratio is used for manufacturing the dual-color polyethylene film. The raw material ratio and the process are adopted for preparing the dual-color polyethylene film for the operating room disposable drapes, the thickness of the film is moderate and is 0.05 mm, the puncture resistance performance is prominent, the mechanical performance is excellent, and the film can meet the requirement of the operating room disposable drapes.

Description

technical field [0001] The invention relates to a two-color polyethylene film for one-time draping in an operating room. Background technique [0002] The single-color film previously used in the operating room for disposable surgical drapes does not distinguish between the front and back sides, and it is difficult to distinguish the disinfection side before the operation, which brings hidden dangers to the health of patients. In order to distinguish the positive and negative sides, the current method is mainly to print or compound a layer of glued composite film of other colors on one side of the film. The ink used in the printing process of printing the film on one side will cause peculiar smell; the glued composite film not only needs to produce two different colors. Film, but also increase the adhesive, resulting in an increase in film thickness, which increases the process and cost to varying degrees.
