Problems solved by technology

[0003] 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.
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

Abstract

The invention discloses a degradable packaging bag for express service. The degradable packaging bag is prepared from the following raw materials in parts by weight: 80-100 parts of polypropylene, 30-50 parts of polypropyl alcohol, 5-10 parts of polylactic acid, 5-10 parts of chitin, 5-8 parts of propyl acetate, 3-5 parts of sodium hydroxide, 3-5 parts of potassium permanganate, 20-30 parts of corn starch, 10-15 parts of cellulose, 10-15 parts of calcium carbonate, 20-30 parts of a filler, 3-5 parts of ferric acetylacetonate, 3-5 parts of an inorganic pigment, 5-10 parts of a plasticizer and 2-5 parts of a coupling agent. The packaging bag for express service has a photosensitive degradation effect and a biological degradation effect. When the plastic bag is in a humid environment, propylacetate, sodium hydroxide and potassium permanganate in the plastic bag can break double bonds in polypropylene and polypropanol, the degradation speed is increased, and the degradation degree is increased.

Description

technical field [0001] The invention relates to the technical field of plastic bag degradation, in particular to a degradable express packaging bag. Background technique [0002] Plastic is a polymer material, a series of macromolecular polymers that can be prepared from petroleum. For example, polyethylene, polypropylene, polyvinyl chloride, polypropylene alcohol, and the like. The plastic bags currently used are formulated from many materials, among which high molecular polymers (or synthetic resins) are the main components of plastics. In addition, in order to improve the performance of plastics, various auxiliary materials must be added to the polymers. , such as fillers, plasticizers, lubricants, stabilizers, colorants, etc., can become plastics with good performance. 1. Synthetic resin Synthetic resin is the most important component of plastics, and its content in plastics is generally 40% to 100%. Most of the plastics need to add other substances in addition to the ...
