Problems solved by technology

[0002] General products include pure film packaging bags: pure film bags are made of general high molecular polyethylene, because of its anisotropic molecular structure, polyethylene has average puncture resistance and tear strength, and extremely poor air permeability. It is not conducive to the penetration of sterilizing factors, and it is a great challenge to the effectiveness and analysis of EO sterilization. Sterilization with this kind of packaging bag often has poor sterilization effect and large toxic residue; it is due to extremely poor air permeability, which cannot meet the air permeability Good, high tear strength, puncture resistance, high moisture resistance requirements

Abstract

The invention relates to a medical sterilizing and packaging header bag and a preparation method thereof, belonging to an improvement on a process for processing a packaging material by using extrusion compound equipment in the flexible packaging industry and particularly belongs to an improvement on a process for processing a packaging material in the flexible packaging industry. The medical sterilizing and packaging header bag is prepared by scalding a breathable heat-sealing environment-friendly waterborne adhesive coated on a Dupont patented product Tyvek as a breathable material and a three-layer co-mixed polyethylene film prepared according to a special formula, so that the prepared packaging header bag has no film breaking when being stripped, has no secondary pollution risks, can completely meet the requirements of high resistance, good breathability, high tearing strength, puncture resistance, high moisture resistance and stripping cleanness and can also meet the requirements of packaging bags for sterilizing, storing and packaging second-class and third-class medical instruments.

Description

technical field [0001] The invention relates to a medical sterilized packaging head bag, and relates to the improvement of the processing technology of the packaging material in the flexible packaging industry, in particular, it relates to a pouch which utilizes modified polyethylene to meet the requirements for sterilization and storage packaging of high-barrier medical devices. method. Background technique [0002] General products include pure film packaging bags: pure film bags are made of general high molecular polyethylene, because of its anisotropic molecular structure, polyethylene has average puncture resistance and tear strength, and extremely poor air permeability. It is not conducive to the penetration of sterilizing factors, and it is a great challenge to the effectiveness and analysis of EO sterilization. Sterilization with this kind of packaging bag often has poor sterilization effect and large toxic residue; it is due to extremely poor air permeability, which...
