Since the solvent-based instant coating technology seriously threatens the health of operators and users in the process of coating and later use, the relevant state departments have explicitly eliminated the solvent-based instant coating film machine. In order to maintain the health of production personnel and users, the implementation of the ban, the National Printing Standardization Committee is brewing drafting new national standards for laminating processes. As a solvent-based coating process widely used in the coating of books and periodicals, food, medicine, and beverage packaging materials, it is a technology currently widely used in China. The main disadvantages are: 1. The use of solvents such as benzene and ethanol in production pollutes the environment and endangers the health of operators; Disposable Chopsticks,Disposable Birch Choopstick,Disposable Popular Choopstick,Disposable Biodegradable Choopstick Dalian Yongtailong Wood Industry Co.,Ltd , https://www.ytldisposablegoods.com
2. It is easy to cause fire and explosion;
3. The coated textbooks, foods, medicines, and beverages have solvent residues, which may cause pollution to primary and middle school students and foods, medicines, and beverages, and endanger the health of relevant personnel;
4. The matching drying equipment is needed, which increases the energy consumption;
5. Compared with other laminating technologies, it has slow speed, poor quality and high comprehensive cost.
