The production of metal packaging boxes refers to the printing of decorative graphics on the surface of metal packaging to make the product more attractive or descriptive. The printing process of metal packaging boxes is very complicated and strict. The following Guangdong Printing Iron Can Factory-Mai’s Can Industry introduces the production process of metal packaging boxes:
1. Plate making. Now the packaging boxes on the market are exquisite and chic, beautiful and beautiful, so the color choices for printing on metal packaging boxes are also varied. Usually a beautiful metal packaging gift box not only has the four basic colors of CMYK, but also There are spot colors such as gold and silver.
2. Material selection, the material of the metal packaging box is generally made of tinplate or aluminum, and the proportion of tinplate used is greater than that of aluminum. Tinplate is mainly used as a material for various gift packaging, food packaging, medical packaging, tea packaging, etc., while aluminum is mostly used in the production of sealed cans for beverages or other liquid packaging. Because tinplate has strong adsorption performance for printing ink, it can print all kinds of patterns, patterns or characters on iron material, which is easy to process and shape.
3. Surface treatment. Generally, the process of surface treatment after printing on metal. Common methods include coating varnish, dumb glue, UV, varnish or dumb oil, etc. The metal surface after passing the gloss glue will be very bright, while the effect after passing the dull glue is relatively fuzzy, which is just the opposite of the effect of the photo glue. Therefore, if you want to perform partial UV treatment, you should choose a dull glue. This processing will have a visual effect. Better, but under normal circumstances, the matte glue should be selected when the printing color is darker, on the contrary, the lighter color will be over the gloss glue effect. It is more important to note that the metal that has passed the dull glue can be partially UV treated, while the metal that has passed the photo glue cannot be used for this operation.
4. Beer processing. Beer is a more important part of the printing process. Only when the die is accurate can the beer be accurate. If the beer process is inaccurate, it will seriously lead to subsequent processes.
5. After the punching process, if you don’t punch, just wipe the glue on the surface, and then you can pack it for shipment.
