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...

Problems solved by technology

Plastic bags do bring convenience to people's lives, but the convenience at this moment brings long-term harm.

[0005] Generally speaking, the hazards of non-degradable popular plastics to the earth include: 1. The recycling value of plastic bags is low, and they are easy to be scattered in urban streets and tourist areas during use. The plastic structure is stable and not easy to be degraded by natural microorganisms. Long-term inseparability in natural environment

This means that if waste plastics are not recycled, they will become pollutants in the environment, exist permanently and accumulate continuously, which will cause great harm to the environment.

2. Affect agricultural development

3. Waste plastic products discarded on land or in water bodies are swallowed by animals as food, resulting in animal death

4. Landfilling of waste plastics will not only occupy a large amount of land, but also the occupied land will not be restored for a long time, affecting the sustainable use of land

Due to the particularity of the items it packs, medical packaging materials need its packaging materials to meet certain requirements, such as the degradability of materials. Although some research has been done on degradable materials at home and abroad, the degradation performance is still Poor, and if the degradable material is prepared by modification with components with strong degradability, the physical properties of the material often do not meet the requirements
