Food Paper Packaging Problem, What Should Be Solved First?
Food paper packaging has now appeared in every corner of people's lives. In the city, there are various cartons, paper bags, paper cans and paper cans. The use of steamer paper and baking paper is also increasing year by year. However, the media frequently exposed scandals about food packaging, the reason is that some unlicensed factories use non food grade paper and ink at will. It can be said that starting from the source, preventing unqualified paper from entering the field of food paper packaging is the top priority of food safety issues.
Spot check the problem of paper, a major performance is the addition of fluorescent whitening agent. Fluorescent whitening agent is a kind of chemical dye, which has carcinogenic effect and poses a potential threat to people's health. According to the regulations, it is not allowed to be used on food packaging. Some manufacturers use recycled paper in the production process or part. In the recycled waste paper, there may be fluorescent whitening agent. In addition, adding fluorescent brightener to the waste paper pulp can increase the brightness of the paper, which is much lower than that of the paper using raw wood pulp.

Paper has been used as food packaging in foreign countries for many years. In the United States, before food is put on the market, manufacturers should provide the FDA with information about the performance of packaging materials, chemical composition and the impact on the environment. FDA needs to carry out a series of tests on packaging materials, including how to transfer and accumulate chemical substances into food under heating, refrigeration, high pressure and other conditions, how many such substances may be exposed to or absorbed by consumers, and the level below which they will not affect their health. After that, the FDA will issue a packaging report and use the data to decide whether to approve such packaging on the market. If you use food packaging without FDA certification, you will be severely punished.
To sum up, in order to solve the problem of food packaging, first of all, the unqualified paper should be introduced into the field of food packaging.
