We need to pay attention to a lot of customized octahedral sealing bags. The following small series briefly talks about the matters needing attention and production steps of customized octahedral sealing bags. Locate the product packaging style and the information to be expressed. For example, the bag in your picture above: octahedral bag manufacturer, size 15x21 + 7cm, material: pet + VMPET + PE. These are the parameters of the bag. Before making a bag, you must make clear the specifications, materials, thickness and bag type. According to these data, let your designer or packaging factory design and make packaging bag drawings. You can design more copies, give reference and finally determine the bag.
1. Packaging design: This is to design the layout of the food bag according to the requirements of the food company. A good design layout of octahedral sealing bag can improve the sales volume of products.
2. Plate making: according to the confirmation draft of the design of the octahedral sealing bag, the copper plate needed on the octagonal bag printing machine is made. The version into a cylinder, and is a set, not a single one, the specific size of the plate number to be determined according to the previous step of packaging design.
3. Layout printing: the specific work content on the octagonal bag printing machine is printed according to the first layer material confirmed by the food company (the confirmation of material can refer to the basis of vacuum bag), and the effect picture printed is not much different from the design draft.
4. Composite: the so-called composite is to glue the two total materials together and stick the ink surface between the two layers of materials, such as PA (nylon) / PE (reinforcement). Among them, nylon is the first layer of material, that is, printing material, and PE (reinforcement) is the second layer material, namely composite material. In some cases, there will be a third layer and a fourth layer material. For example, the third layer is needed for ordinary aluminum 5 and foil bag (OPP film / Al foil / PE reinforcement). Note: it is usually necessary to check the previously printed materials before lamination, and eliminate the materials with poor printing effect.
5. Eight side sealed bags for curing.
6. Eight side sealing bag for cutting or bag making: slitting is for automatic packaging film (pillow type packaging film), bag making is to make one packaging bag with bag making machine.
