Food packaging bags are important measures to protect food from pollution, deterioration, and food safety. If the food packaging itself is not safe, it will not be safe. What are the safety risks of food packaging bags, and how can we strengthen management?
Food packaging bag safety risk one: color printing ink
In order to make food packaging bags look more beautiful and attract consumers' attention, color printing is an important means. The ink often contains various solvents: 1, alcohol solvent: ethanol (alcohol), isopropanol, n-butanol; 2, ester solvent: ethyl acetate, butyl acetate, isopropyl acetate; 3, benzene solvent : toluene, xylene; 4, ketone solvent: cyclohexanone, acetone, methyl ethyl ketone (butanone); sometimes mixed with heavy metals in the ink. The state has strict requirements for color printing inks for food packaging bags, and there are clear regulations for ink components and solvent residues. It is safer to use alcohol solvents in food packaging, but his residue cannot exceed the standard. These solvents and heavy metals have certain harm to the human body and are also a source of risk for color printed food packaging bags.
