Let's take a look at it
1、 Printing process

If you want to have excellent appearance display function, excellent planning is the condition, but more important is the printing process. Food packaging bags often touch food directly, so the premise of printing is also very serious. Whether it is ink or solvent, should be in accordance with food inspection standards.

2、 Composite process of standing zipper bag manufacturer
Most of the food packaging bags are made of composite structure, which has the advantage of heat sealing, blocking ink layer and preventing food pollution. There are many kinds of compounding methods, such as solvent free, dry and extrusion. Different composite methods have different advantages and disadvantages, which are the needs of food manufacturers to pay attention to.
3、 Ripening process
Can the material be processed immediately after it is compounded? No. Because the composite glue is not completely dry, the composite strength at the moment is very low, and the data is very simple, which will show separation. At this time, it is necessary to strengthen the composite strength by means of ripening. The so-called ripening is to allow the data to be stored naturally at a relatively stable temperature (generally more than 30 degrees), and the time is usually several to dozens of hours. Its function is to accelerate the drying process of glue and greatly enhance the composite strength.
4、 Food standing zipper bag manufacturer cutting and bag making process
Generally speaking, after the ripening time is enough, the specified standard slitting and bag making process can be carried out. Slitting is to cut the large roll material into small roll material, which is convenient for food manufacturers to package themselves; bag making is to make bag shape by bag making machine according to customer requirements.
5、 Inspection process
Excellent product quality is closely related to the seriousness of inspection work. After the completion of the product, we have to go through a lot of manual inspection homework to remove the defective products. Only the qualified products can be handed over to customers.
