Medical paper-plastic composite blue film and preparation method thereof

Abstract

The invention discloses a medical paper-plastic composite blue film and a preparation method thereof, the medical paper-plastic composite blue film is formed by combining a biaxially orientated polyester film which is printed and coated and a cast polypropylene film, the cast polypropylene film is divided into three layers of a corona layer, an intermediate layer and a heat seal layer, the raw material component of the corona layer is additive-free binary copolymer propylene resin RF401, the raw material components of the intermediate layer are 85-95% of binary random copolymer polypropylene resin F800E and 5-15% of ethylene-butene elastomer A-4085S, and the raw material components of the heat seal layer are 85-90% of binary copolymer propylene resin RF402 containing anti-sticky slipping agent, 5-15% of ethylene-butene elastomer A-4085S, 1-2% of inorganic anti-sticky agent ABPP10S and 0.5-1.5% of slip modified masterbatch SE07PP. The preparation method comprises the steps of printing, preparation of the cast polypropylene film, combination of the biaxially orientated polyester film and the cast polypropylene film and cutting. The medical paper-plastic composite blue film is matched with medical packing paper which can carry out heat sealing, steam sterilization and air infiltration blocking for carrying out packing of medical items, thereby reducing the packing cost and realizing safety performance of packing applications and environment-friendly treatment of packing wastes.

Description

technical field [0001] The invention relates to a medical packaging film and a preparation method thereof, in particular to a medical paper-plastic composite blue film and a preparation method thereof. Background technique [0002] In recent years, with the development of medical and health services, people have higher and higher requirements for medical consumption. The packaging of any medical equipment is for one-time use to prevent cross-infection; at the same time, combined with the concept of environmental protection, packaging waste must meet the recycling requirements. Reuse needs. [0003] For a long time, paper-paper composite medical packaging films have been used in domestic and foreign markets for high-temperature sterilization packaging of medical gauze sheets, surgical consumables (instruments), medical catheters, sterile cotton swabs (balls), and ophthalmic and dental equipment. In terms of packaging form, the medical safety is guaranteed to the greatest ext...

AI Technical Summary

Problems solved by technology

However, the use cost of paper-paper composite medical packaging film is relatively high, the steam sterilization operation after the finished product packaging has a greater risk of breaking the package, and the package cannot be displayed intuitively in front of the user
