When we make food packaging bags, we will inevitably have stocks, but some food packaging bags will have some odors. This kind of bag packaging food is not safe. 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.

 

3, food packaging bag compound do not use high-odor single-component PS composite adhesive.

 

4. The inner film material used in the composite of the food packaging bag should be inspected for odor. Do not use the PE film with the filler as the composite inner substrate.

 

5, food packaging bags try to improve the printing speed, try to reduce the viscosity of printing ink, reduce the amount of ink, keep the drying box and plant ventilation, and reduce the ink and ink solvent residue to a very low.Guide: We will inevitably have stocks when making food packaging bags, but some food packaging bags will have some odors.
