Simple production process of color bags:
a. The production process of the color bag: printing into the film (there is one plate rolling for each color when printing, the engraving of the plate is concave plate engraving), the ink flows continuously during printing, because the ink will condense In the ink printing and film printing, a scraper is set, and the scraper scrapes off the ink where the plate is rolled, so that the recessed plate roll can be printed. Strip-like ink contamination can occur if the blade is dusty. The phenomenon of dot-like ink contamination is caused by dot-like ink contamination caused by ink splashing onto the packaging film during rolling printing.
b. After the film is printed, the compounding is started. Generally, the dry-wet compounding method is adopted, that is, the color-printed film is coated with glue, and then baked into a baking for 2 minutes and then compounded with PE, and the composite tension is 5.6 kg. The bags used by our company are two-layer composite.
c. Curing: The film after curing the glue is cured. The curing effect is mainly to firmly adhere the glue, and the curing is generally cured at 50 ° C for 24 hours. In fact, the composite film is stored in a 50 ° C environment for 24 hours. If the time and temperature are not satisfactory, the film composite will not be tight.
d. After curing, the film is then inspected. The inspection product is to input the printed matter of the standard sample into the computer, and then pass the cured film through a white screen controlled by the computer, and the defective product will directly paste a black film on the film. symbols of.
After the e-test, the film is slit.
f. After the slitting, the film is bagged, and the bag is automatically bagged by a machine directly, and the edge is automatically sealed during the bag making process, and compacted.
