Packaging design: This is to design the layout of the food vacuum bag according to the requirements of the food company. A good design layout of food vacuum bags has a good effect on improving the sales volume of products. First of all, our company provides the design of food vacuum packaging bags for free. Plate making: It is to make the copper plate required on the food packaging printing machine according to the confirmation draft of the food packaging design. The plate is a cylinder, and it is a complete set, not a single one. The specific size and number of plates should be determined according to the packaging design of the previous step. The specific work content on the food packaging printing machine is based on the first confirmed by the food company. A layer of material (the confirmation of the material can refer to the basis of the vacuum bag) is printed, and the printed renderings are not much different from the design drawings. Composite: The so-called composite is to bond the two total materials together, and stick the ink surface in the middle of the two layers of materials, such as pa (nylon)/pe (reinforced), where nylon is the first layer of material, that is, the printed material, pe (Reinforcement) is the second layer of material, that is, composite material. In some cases, there will be a third and fourth layer of material. For example, ordinary aluminum foil bags (opp light film/al aluminum foil/pe enhancement) need a third layer. Note: It is usually necessary to check the previously printed materials in one step before compounding, and eliminate the materials with poor printing effect. Curing Slitting or bag making: Slitting is for automatic packaging film (pillow packaging film), and bag making is to use a bag making machine to make one packaging bag.
