According to the requirements of the food company, the first layer of material is confirmed. The food packaging we see in our daily life is in a variety of forms. The ink side is glued in the middle of the two layers of material, and the food packaging is made according to the design of the food packaging bag. . Among them, nylon is the first layer of material, that is, the printing material, and in some cases there will be a third layer, which usually needs to be fed to the previously printed material in one step before compounding, and the printed renderings are not much different from the design works. The food packaging forms that we see in our daily life are varied, and the reason is that the requirements of food packaging technology will vary according to the type and characteristics of the food. So how is food packaging produced? 1. Packaging design: According to the requirements of the food company, this is the layout of the food vacuum bag. A well-designed food packaging bag layout is a great way to increase sales. 2. Plate making: Based on the confirmation of the basic knowledge of food packaging bags, it is the copper plate required for food packaging printing machines. Versions are cylinders, the whole collection is not monolithic. The specific size is determined according to the packaging design in the previous step. 3. Layout printing: The specific work content of the food packaging printing machine is printed according to the first layer of materials confirmed by the food company (the confirmation of materials can be based on vacuum bags), and the printing renderings and design drawings are not available. The difference is too great. 4. Composite material: The so-called composite material is to bond two materials together, and the ink surface is stuck in the middle of the two layers of materials, such as pa (nylon)/pe (reinforced), among which nylon is the first printing material The material layer, pe (reinforced) is the second layer material as composite material, and in some cases there will be third, fourth layer material. If you do normal aluminum 5, aluminum foil bags (opp light film/aluminum foil/pe enhanced) you need a third layer. NOTE: It is often necessary to inspect previously printed material prior to lamination to eliminate poorly printed material. 5. Food packaging bags are solidified. 6. Food packaging bags are used for slitting or bag making: slitting is used for automatic packaging film, and the bag is made by a bag making machine.
