Packaging design: This is to design the layout of the food vacuum bag according to the requirements of the food company. A good food vacuum bag design layout has a very good effect on increasing product sales. Our company provides free design services for food vacuum packaging bags.
Plate making: It is to make the copper plate needed 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 whole set, not a single one. The specific size and the number of plates should be determined according to the packaging design of the previous step (the plate fee is based on the size of the bag imposition)
Layout printing: The specific work content on the food packaging printing machine is printed according to a layer of material confirmed by the food company (the material is indeed the basis of the vacuum bag), and the printed renderings are not much different from the design drawings.
Composite: The so-called composite is to bond two total materials together, and stick the ink surface in the middle of the two layers of materials, such as pa (nylon)/pe (reinforcement), where nylon is a layer of material that is printed material, Reinforcement) is a two-layer material, that is, a composite material. In some cases, there will be a third and a fourth layer of material. For ordinary aluminum foil bags (opp light film/al aluminum foil/pe reinforcement), the third layer is required. Note: It is usually necessary to check the previously printed materials in one step before lamination, and eliminate the materials with poor printing effect.
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 packaging bags one by one.
