Abstract

The invention discloses a medical packaging material. The medical packaging material is prepared from, by weight, 12-23 parts of polycarbonate, 8-18 parts of polyurethane, 0.5-1.2 parts of polyethylenimine, 0.5-1.2 parts of polydimethylsiloxane diquaternary amine, 0.4-1 part of trichlorofluoromethane, 4-9 parts of dichlorodifluoromethane, 15-28 parts of polylactide, 1.5-6 parts of calcium carbonate, 0.5-1 part of sodium dibutyl naphthalene sulfonate, 15-30 parts of polyethylene glycol, 6-12 parts of acrylic resin, 4-9 parts of vinyl-vinyl acetate copolymer and 2.5-6 parts of borax. Compared with the prior art, the medical packaging material has strong resistance to high temperature and high tensile strength, does not easily deform after high temperature and high pressure sterilization treatment and is especially suitable for the medical field.

Description

technical field [0001] The invention relates to a packaging material, in particular to a medical packaging material and a preparation method thereof. Background technique [0002] Packaging materials are widely used in various fields of our society, such as medical packaging materials and food packaging materials, etc., in order to improve the hygiene status of the medical industry or food industry, it must allow the effective penetration of the selected sterilant, and be suitable for Relevant conditions for other sterilization methods. Conventional medical packaging materials such as polyvinyl chloride and polyethylene will be deformed under long-term sterilization conditions, and the relevant mechanical properties of conventional medical packaging materials will also be reduced after deformation, so that the packaging materials cannot meet the requirements for use . Contents of the invention [0003] The purpose of the present invention is to provide a medical packagin...
