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 double-color polyethylene film for a disposal bed sheet of an operating room. The double-color polyethylene film for the disposal bed sheet of the operating room is prepared by the following steps of: extruding a high-pressure low-density polyethylene resin, a metallocene linear polyethylene resin, masterbatch and an antifoaming agent from two screw extruders respectively and plasticizing, extruding by using a T-type flat joint die head to form a sheet, laminating and shaping by an embossing steel roller and a rubber roller, and then drawing and cutting ear sides. The aims of distinguishing front and reverse sides can be fulfilled under the condition of not adopting ink printing or an adhesive; when a double-color film is prepared by an ink printing process, equipment is added and solvent-based ink is needed to be used; when the double-film is prepared by bonding of the adhesive, two kinds of different films are needed to be produced, and then are bonded by the adhesive, and bonding equipment is high in manufacturing cost; compared with the two kinds of double-color films, the double-color polyethylene film for the disposable bed sheet of the operating room, which is prepared in the raw material proportion by a process has the advantages that the thickness is appropriate and is 0.05mm, and the double-color polyethylene film is excellent in puncture resistance performance, and mechanical property, and meets the using requirements of the disposable bed sheet of the operating room.

Description

technical field [0001] The invention relates to a two-color polyethylene film for one-time draping in an operating room. technical background [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.
