Problems solved by technology

When disinfected or sterilized by high-temperature steam, it is easily damaged and cannot play the role of blocking bacteria; if medical devices are loaded in full plastic packaging and sterilized with ethylene oxide, the sterilization will be incomplete or gas will remain in the packaging bag Inside, there is a certain amount of toxic residues, and it is difficult to meet the requirements of the ISO11607EN868 international standard for sterilization packaging of medical devices

Abstract

The invention discloses a production method for bactericidal packing paper, which comprises the following steps of: (1) preparation working procedure of applying glue solution to pulp; (2) preparation working procedure of applying glue solution to a surface; (3) working procedure of sizing agent repulping, selecting Southern pipes produced in America to make pulp, adding sodium carbonate and carboxymethyl cellulose into a repulping liquid; (4) working procedure of pulp matching, adding a wet strength agent; (5) working procedure of webbing and forming; (6) working procedure of applying glue solution to the surface, using modified tapicoa starch and polyvinyl alcohol for applying the glue solution to the surface; and (7) completion working procedure. The bactericidal packing paper has good air permeability, high surface strength, tearing resistance after disinfection and high bursting strength and can block bacterium invasion.

Description

technical field [0001] The invention relates to a production process of special paper, in particular to a production method of sterilization wrapping paper. Background technique [0002] Sterilization packaging base paper is the base paper for the production of medical packaging paper. It is processed from plant fibers. The base paper produced as a medical packaging material has strict requirements on hygiene and quality. The base paper must have good air permeability and good air permeability. Strength performance, especially wet swelling strength, it directly affects the safety and sanitation of medical equipment, and some domestic products are generally unqualified in this index. The base paper currently produced is generally made by pulping, beating, batching, online molding, surface sizing, drying, coiling, and cutting. Generally, domestic or Russian wood pulp is used in the crushing process, and no other pulp is added to the crushing solution. Chemical raw materials, ...
