Preparation method of plastic packaging bag capable of sterilizing and preventing mosquitoes

Abstract

The invention provides a preparation method of a plastic packaging bag capable of sterilizing and preventing mosquitoes, and belongs to the field of plastic packaging bags. The preparation method of the plastic packaging bag capable of sterilizing and preventing mosquitoes comprises the following specific steps: picking whole mugwort plants before and after Dragon Boat Festival, crushing the wholemugwort plants through a crusher, weighing dry mugwort, preparing a mixed solution A, preparing plastic powder B containing mugwort extract, preparing antibacterial insect-expelling master batch C, and preparing the packaging bag containing mugwort extract. In order to reduce invasion and mildewing of mosquitoes, the mugwort extract has the effects of sterilization and mosquito prevention, the mugwort extract and the plastic powder are mixed to prepare the functional master batch, then the plastic packaging bag capable of sterilization and mosquito prevention is prepared, and the problems that an existing plastic packaging bag preparation method does not have the sterilization effect, and after long-time use, the food is easy to mildew; and the food is easy to damp and deteriorate duringstorage are solved.

Description

technical field

[0001] The invention belongs to the technical field of plastic packaging bags, and in particular relates to a method for preparing a plastic packaging bag capable of sterilizing and preventing mosquitoes. Background technique

[0002] Plastic is a compound formed by the polymerization of a large number of small molecular units through covalent bonds. It has the characteristics of good toughness, durability, easy processing, and low cost, and is now widely used. Plastic packaging bags are divided into two categories according to their uses: one is food-grade packaging bags, which are made of polyethylene (PE), polypropylene (PP) and other raw materials, which are non-toxic and can be used to package food; the other is non-food packaging bags. High-grade packaging bags are made of materials such as polyvinyl chloride (PVC) or waste recycled plastics. They cannot be used for packaging food, but they can be used for making garbage bags and other purposes. [000...
