The methods for preventing mold in color box printing packaging are as follows:

1. Dry and anti mold packaging technology. Under dry conditions, mold cannot reproduce and the product will not rot.

2. Modified atmosphere packaging technology for preventing mold and corrosion. Under the premise of sealed packaging, by changing the composition of the air inside the color printing packaging, the concentration of oxygen is reduced, creating a low oxygen environment to suppress the life flow of mold and rot microorganisms and the respiratory intensity of biological products, thus achieving the goal of preventing mold and rot of packaged goods.

3. Chemical agent anti mold and decay packaging technology. Use anti mold and anti-corrosion chemicals to properly handle the items and packaging materials to be packaged.

4. Gas phase anti mold and decay packaging technology. A volatile anti mold and anti-corrosion agent that uses the gas generated by its volatilization to directly contact with moldy microorganisms, achieving the goal of killing and inhibiting their growth, and preventing commercial moldy decay.
