There are many types of plastic packaging, but they can be roughly divided into the following four categories: three-side seals, flat middle seals, mid-bottom seals and other sheets.
Production process that can be placed on the same set of plate rollers:
1. Three-side sealing: Sealing near the package. Discord and back are the dimensions of the product. This kind of scheme is not restricted and has a strong sense of collectiveness. Since the front and back sides are equal in scale, the first scheme can be used to prevent the other side. Corresponding plan. The front and back of the plate making time should be placed on the same plate roller.
2. Mid-bottom seal: Discord is the product packaging, and the back is sealed. The width of the back is commensurate with the width of discord. Any plan is an integrated scheme, and 1 cm edge sealing is added on both sides.
3. The flat middle seal is on the bottom of the middle and low seal, plus the flat sides on both sides. The production process that cannot be placed on the same plate roller:
Due to the limitation of material printing, it is necessary to separate the front and back sides of some plastic packages, making plates separately, and cannot be presented on the same set of plates at the same time.
