Paper-plastic packing bag for medical sterilization

Abstract

The invention discloses a paper-plastic packing bag for medical sterilization. The paper-plastic packing bag for medical sterilization is characterized by comprising a surface layer (1) and a base layer (2), wherein the surface layer (1) is connected with the base layer (2) to form a closed cavity (3) for placing contents; the surface layer is formed by coating water-based EVA dispersion emulsion on a piece of dialyzing paper by using an air knife; the base layer is made from a polyethylene and polyester composite film. The paper-plastic packing bag for medical sterilization, disclosed by the invention, can be used for guaranteeing penetration of sterilization factors during sterilization and disintegration of the sterilization factors after the sterilization is ended and is also used for guaranteeing the heat sealing strength; enough heat sealing strength can guarantee no bag explosion during sterilization, satisfy the bacteria resistance of instruments during storage within the guarantee period and further guarantee cleanness and no dust when the pack of an instrument in a medical environment is opened; therefore the requirement of clean removal can be satisfied, medical instrument products are prevented from secondary pollution, and safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical sterilization bags, in particular to a medical sterilization packaging paper-plastic bag with good air permeability, clean peeling and anti-bacteria non-explosive bag. Background technique [0002] The function of medical sterilization packaging materials is used for the packaging of medical device products, which can be sterilized, can be operated aseptically, can provide acceptable microbial barrier performance, and can protect and sterilize the product before and after sterilization Finally, a packaging system that can maintain a sterile environment inside the system within a certain period of time. [0003] At present, there are two main types of paper-plastic bags used in the medical device packaging industry: (1) It is made of EVA hot-melt adhesive grid-coated dialysis paper + composite film technology, and paper-plastic bags with low coating quality are not bonded firmly It is easy to burs...

AI Technical Summary

Problems solved by technology

[0003] At present, there are two main types of paper-plastic bags used in the medical device packaging industry: (1) It is made of EVA hot-melt adhesive grid-coated dialysis paper + composite film technology, and paper-plastic bags with low coating quality are not bonded firmly It is easy to burst the bag, and the paper-plastic bag with high coating quality has poor air permeability, and there may be false seals, which will cause the packaging bag to burst during sterilization and cause the sterilization to fail

(2) The technology of dialysis paper + composite film coated with solvent-based EVA heat-sealing glue is used. This kind of product has difficulty in controlling the heat-sealing viscosity, and the paper-plastic bag with low coating quality does not have enough ironing fastness, and the high-quality coating The fastness of paper-plastic bags is sufficient, but the air permeability is poor, and the paper is easy to rot when peeled off, resulting in the generation of paper dust, which cannot meet the requirements of clean peeling; moreover, the solvent is polluting, not environmentally friendly, and the coating residue is large
