Problems solved by technology

Some food antibacterial wrapping paper is to apply some synthetic antibacterial agent on the surface of the wrapping paper. After long-term use, it also causes certain damage to the human body in the process of killing bacteria.
Moreover, the synthetic antibacterial agent will also make bacteria resistant, and the antibacterial effect will gradually weaken, and then another antibacterial agent must be replaced

Abstract

The invention discloses antibacterial packaging paper. A preparation process comprises: preparation of packaging paper, preparation of a waterproof agent coating, and preparation of an antibacterial agent coating. According to the antibacterial packaging paper disclosed by the invention, the processing raw materials are bamboos and waste timbers. As bamboo fiber is naturally antibacterial, timbers are replaced by bamboos, so that cutting of trees is avoided, the environment is protected, the ecological balance is maintained, waste is turned into wealth as waste timbers are used, and the cost is saved; the bamboo fiber and wood fiber are matched in use, so that the strength and flexibility of paper are remarkably improved and the packaging paper is wide in using range; the waterproof layer and the antibacterial layer are natural materials which do not harm human body and environment and play natural roles of preventing water and resisting bacteria; in a delignification process, the raw materials are pre-treated by using white rot fungi first, so that the time and dosage for delignification by hydrogen peroxide are reduced; hydrogen peroxide further can disinfect and bleach the packaging paper, is safe and non-toxic, and does not cause the environmental pollution, thereby killing two birds with one stone and saving the cost.

Description

technical field [0001] The invention mainly relates to a wrapping paper, in particular to an antibacterial wrapping paper. Background technique [0002] Packaging has two major functions: one is to protect the goods from damage and deterioration during the process of manufacturing, transportation, warehousing and sales; It meets the increasing material and cultural needs of consumers, and promotes and stimulates consumption. As an important packaging material, packaging paper has been widely used in product packaging in various industries. It includes container board and corrugated base paper, white cardboard and white cardboard, beverage flexible packaging paper, special packaging paper, etc. However, the raw materials of traditional paper and cardboard mainly rely on wood pulp and straw pulp made from trees. Excessive dependence will lead to a large amount of wood being cut down, which will lead to soil erosion and cause increasing damage to the earth environment on which...
