Abstract

The invention discloses steaming and boiling resistant packaging bag coating and a manufacturing method thereof. The packaging bag coating is prepared from, by weight, 1-2 parts of tung oil, 1-2 parts of tung oil anhydride, 0.3-0.5 part of a silane coupling agent, 20-40 parts of calcium carbonate, 15-25 parts of polypropylene, 10-20 parts of polyvinylidene chloride, 5-10 parts of chitosan, 5-10 parts of alanine, 3-7 parts of talcum powder, 2-5 parts of nano titanium dioxide, 1-2 parts of isobutyl methacrylate and 5-7 parts of rosin resin. The manufacturing method includes steps of grinding, modifying, stirring and drying. The coating has advantages of steaming and boiling resistance, transparency, environmental friendliness, safety, nontoxicity and low cost and can be directly used for food packaging after compounding, and food along with packaging bags can be steamed and boiled together to realize high-temperature disinfection and sterilization, so that consumers can eat directly after opening the packaging bags.

Description

technical field [0001] The invention relates to the field of packaging coatings, in particular to an anti-corrosion coating for packaging bags and a manufacturing method thereof. Background technique [0002] In today's meat processing, it is the mainstream to provide consumers with fresh or frozen meat. The following shortcomings are common in this food packaging application: [0003] 1. The food provided must be cooked by the consumer before use, which is a waste of time. [0004] 2. The food provided has not been sterilized by high temperature, and the shelf life is not long. [0005] 3. The packaging is opaque, and the packaged objects cannot be seen. [0006] With the improvement of people's quality of life, consumers pay more attention to food safety and life rhythm, and the development of environmentally friendly packaging materials is the mainstream trend today. Contents of the invention [0007] The technical problem to be solved by the present invention is to ...
