The state of food packaging products testing center engineer Xiang Bin explained, this shows that the bonding process and film thickness of paper is not obvious problems, the reason for alcoholic beverages will leak, because alcohol is volatile, strong permeability,are easier to use and paper cups in organic solvents, resulting in leakage.
