When designing, we must give reference and finally determine the bag.
In the design, special attention should be paid to the text information, address, company name and other important information on the packaging bag.
Second, printing, after the raw materials are prepared, use a high-speed printing machine to print the surface film. During printing, the ink is constantly flowing because the ink will condense, when printing with ink and film, a scraper is inlaid. The scraper scrapes the ink at the protruding place of the plate roll, so that the recessed plate roll can be printed.
If the scraper is stained with dust, strip-shaped ink pollution will occur.
The phenomenon of dot-like ink pollution is caused by the splash of ink on the packaging film during rolling printing, resulting in dot-like ink pollution.
Three, composite and curing, the printed surface film and easy heat sealing inner film with special glue special high-speed peritoneal machine for composite.
After the compounding is completed, it needs to be cured for more than 24 hours in a curing chamber above 45 degrees, so that the food packaging bag is not easy to delaminate.
