So what should we do when the food bags are smelly? Today, Xiaobian will talk to you. The analysis is proposed for the majority of users: the appearance of odor in food packaging bags, mainly from ink solvents or composite adhesives and composite adhesive solvents for printing inks, some of which come from the inner film of composite packaging; therefore, it should be noted when making composite packaging bags:
1, the design of food packaging bag printing pattern should choose less color and monochrome elements, try to avoid the full version of the printed pattern.
2. Do not use the odorous surface printing ink when using the printing ink for the food packaging bag. Do not use high boiling solvents containing impurities such as tar benzene, mixed benzene, and recovered solvents.
