Medical degradable package bag and preparation method of same

Abstract

The invention discloses a medical degradable package bag and a preparation method of same. The medical degradable package bag includes, by weight, 50-60 parts of polypropylene, 8-15 parts of calcium carbonate, 1-4 parts of nano titanium dioxide, 10-20 parts of carboxyethyl cellulose, 7-9 parts of aluminum oxide, 1.2-1.4 parts of tetrabutyl titanate, 12-14 parts of dimethylformamide, 60-65 parts of PVC, 2-3 parts of sodium tripolyphosphate, 1-2 parts of magnesium stearate, 13-15 parts of acetyl tributyl citrate, 1-1.5 parts of 2,6-di-tert-butyl-4-methylphenol, 4-6 parts of 3-hydroxybenzoic acid, 1-2 parts of silica gel, and 4-6 parts of diethylene triamine, The medical degradable package bag has very excellent high-temperature-sterilization-resistant performance and has high mechanical performances, such as tensile strength and breaking strength, etc.; the package bag, when being wasted, can be auto-decomposed under effects of enriched oxygen and microorganisms to finally generate CO2 and H2O, so that the package bag is ecological and environment-friendly.

Description

technical field [0001] The invention belongs to the field of packaging materials, and relates to a packaging material and a preparation method thereof, in particular to a medical degradable packaging bag and a preparation method thereof. Background technique [0002] Medical packaging materials have a wide range of uses in the medical field. Medical packaging materials must allow the effective penetration of the selected sterilant and apply to other relevant conditions for sterilization methods. Medical packaging materials must also ensure the sterility of the contents before the package is opened. Pharmaceutical packaging materials should also facilitate the aseptic operation when the user opens the package without contaminating the contained items. In addition, the items in the medical sterile packaging materials must also maintain sterility during use. [0003] Under the sterilization conditions with a temperature of 120°C to 135°C, conventional medical packaging materi...
