Self-supporting zipper bags, especially food self-supporting zipper bags, are "personal clothing" for food ". Their safety in raw and auxiliary materials and printing technology directly affects the quality and safety of food, and then has an impact on human health and society. Therefore, when using this type of bag, we must pay attention to the safety and quality of its use. So what are the main advantages of the use of self-supporting zipper bags?

The use of green materials in the green printing of self-supporting zipper bags can reduce the emission of volatile organic compounds (VOC), control the migration of residual chemicals in self-supporting zipper bag materials and containers to vacuum-packaged food and medicine, and make self-supporting zipper bags More environmentally friendly and safer, which is very beneficial to public health, environmental protection and printing companies. Especially in large cities with a large number of people, the frequency of using food bags is relatively high, which requires that the use of self-supporting zipper bags must be green and environmentally friendly, so as to have a positive impact on the greening of the city.

Self-supporting zipper bag green printing is not only conducive to the health and environmental protection of self-supporting zipper bag users, but also the social and economic benefits of self-supporting zipper bag printing enterprises are "win-win" good.

While fulfilling social responsibilities and practicing the "people-oriented" scientific development concept, it can also improve employees' sense of belonging and identity, thereby improving work efficiency and production efficiency. On the other hand, the green free-standing zipper bag is the general trend. The early implementation of packaging green printing can seize market opportunities, win customers, win the market, and obtain economic benefits.

Green printing is the future development direction of the global packaging and printing industry, and relevant domestic institutions and industry organizations are also actively guiding and promoting. "Environmental Labeling Product Printing Technical Requirements Standard Part I: Lithographic Printing" has been released. The General Administration of Press and Publication is actively cooperating with the Ministry of Environmental Protection to promote the introduction of gravure green printing standards and further standardize the green printing of packaging. In addition, the inspection of packaging should be more careful to avoid defective products in the market.
