Paper bag packaging printing ink

The printing ink packaging and solid waste treatment solution: PEONY paper bag printing ink uses imported food grade kraft paper as raw material and exclusive patented Nano coating technology. Inside the paper bag six layers of organic Nano coating are applied to achieve the same oxygen barrier effect as iron can; after the printing ink in the paper bag runs out, the leftover is only 0.3%, far less than 7% inside an iron can. That can solve the service wear and solid waste pollution problems of iron cans.
