Plastic bags are everywhere in our daily lives, so do you know about the production process of plastic bags? Today, Jiuzhi Plastics Co., Ltd. tells you about the process of making Plastic Packaging Bags, hoping to help everyone better understand the packaging bags . The first design artwork, the design of the plastic packaging bag is a test for the designer, which also requires detailed communication between the customer and the designer. After the customer confirms the pattern, the text, contact information, size and other information must be carried out. Carefully confirm and avoid losses. The design artwork needs to be revised repeatedly according to the customer's requirements. If the goods are urgently needed, please review the artwork as soon as possible.
The second plate making, after the artwork is finalized, requires professional technicians to separate the patterns and repair some unclear areas. Our industry is called a document, and after completing the documents, it takes more than a dozen processes to complete the plate making. I will not introduce them one by one here.
In the third printing, after the raw materials are prepared, the surface film is printed using a high speed printer.
The fourth peritoneum combines the printed surface film with the heat-sealable inner film with a special high-speed peritoneal machine for special glue.
The fifth curing, after the completion of the composite, needs to be cured in a curing chamber of 45 degrees or more for more than 24 hours, so that the plastic packaging bag is not easily delaminated.
The sixth bag, at this time the production of plastic packaging bags has come to an end, the bag making technicians need to have certain skills, must ensure that the plastic packaging bag is well sealed and airtight, and the temperature control of the hot knife has certain technical characteristics. The quality inspector passed the inspection after passing the inspection.
