Food packaging bags are often in direct contact with food, so the printing conditions are also very strict. Both ink and solvent should meet the food inspection standards.

Most of the food packaging bags are made of composite structure, which has the advantage of heat sealing and can isolate ink layer to avoid food contamination. There are many kinds of composite forms, and the commonly used composite methods are solvent-free composite, dry composite and extrusion composite.

3、 Ripening process
Can the material be processed immediately after the material is compounded? No. Because the composite glue is not completely dry, the composite strength at this time is very low, and the material is easy to appear separation. At this time, it is necessary to strengthen the composite strength by aging. The so-called ripening is to let the material in a relatively constant temperature place (generally more than 30 degrees) natural storage, the time is generally a few to dozens of hours, the effect is to speed up the drying process of glue, greatly enhance the composite strength.
4、 Slitting and bag making process of self supporting zipper bag manufacturer
