1. Put in the film for printing (there is a plate roller for each color during printing, and the engraving of the plate roller is gravure engraving). During the printing process, the ink continues to flow, because the ink will condense, so there are embedded in the ink printing and film printing. Use a scraper to scrape off the ink on the protruding part of the plate cylinder in order to print on the concave plate cylinder. If the scraper is stained with dust, it will produce streaky ink stains. Dotted ink contamination is caused by ink splashing on the packaging film during roller printing. .

2. After the film is printed, lamination begins. The films produced by our company generally use the dry and wet lamination method, that is, the adhesive is applied to the color printing film, and then placed in the oven to bake for two minutes, and then compounded with PE. The packaging bags used by our company are double composite.

3. Bond the adhesive to solidify the composite film. The curing effect is mainly to bond the adhesive firmly. Curing is usually carried out at 50 degrees Celsius for 24 hours. In fact, the composite film was stored at 50 degrees Celsius for 24 hours, and the time and temperature are inconsistent. , the membrane is not firmly bonded.

4. Check the cured film. Inspection means inputting the printed matter of the standard template into the computer, and the computer controls the white screen of the cured film. When a defective product appears, a black mark is directly pasted on the film.

5. Cut off the film after inspection.

6. Make the cut film into a bag. The bag making machine will directly make the film automatically. During the bag making process, it will automatically close the edges and punch holes. Through the above detailed introduction, I believe you have an understanding of what an eight-sided sealing bag is and its production process. A certain understanding.
