There are more or less organic solvent residues on the packaging. There are many kinds of residual organic solvents, including benzene, ketone, ester, alcohol, etc. in fact, benzene is not produced in many places. Such solvents will penetrate the film in a short time, causing secondary pollution to the food in the packaging, thus causing leukemia, etc. The large-scale flexible packaging production enterprises represented by Master Kong, Wangwang, Wahaha and Nestle have turned to benzene free compound safe and healthy inks since this year
