Eight edge-sealing food packaging production process

Now a lot of food packaging use eight edge-sealing bag, then eight edge-sealing bag is how to produce? Today eight edge-sealing food packaging manufacturers will take you to understand the eight edge-sealing food packaging production process. A, into the film for printing ( When printing each color has a plate roll, plate rolling is carved intaglio engraving) , when the printing ink is continuously flowing, because the ink condenses, during the printing ink printing and membrane with a scraper, scraper is on board scrape ink roll out, such a hollow plate rolling can be printed. If the blade is stained with dirt on strips of ink pollution phenomenon will occur. Because ink for dot ink pollution phenomena in rolling printing ink will splash into the packaging film and cause the dot of ink pollution. Second, composite membrane after a good printing, for I company produces the film generally adopt wet after legal, color good film is coated with glue into a drying and then 2 minutes and PE composite, the tension of composite is 5. 6公斤。 Our company is the two layers of composite packaging used. Three, cure: the composite membrane after curing glue, glue curing effect is mainly will be able to firmly glue stick, curing general solidification under 50 ℃ for 24 hours. Is really of good composite membrane in 50 ℃ environment for 24 hours. If time and temperature of undesirable membrane composite is not tight phenomenon will occur. Four, curing membrane and then to carry on the goods, after the good goods with the standard sample print input computer, then good curing membrane through the computer control of a white screen, appear nonconforming directly to paste a black mark on the film. Five, the goods after the film is the film after six slitting and cutting with a bag, the bag is by directly to a film for automatic bag making machine, bag making process for automatic edge banding, and pressure.
