Design of plastic packaging knife

The position of the plastic packaging knife should be accurate, and it should be consistent with the pattern on the alien bag, and the appropriate location and size should be reserved for the straw at the seal. If the size reserved at the seal is too large, the seal is not easy to seal and it is prone to leakage problems; if the reserved position size is too small, the straw will be difficult to install. When the size is reserved in the seal, the perimeter of the straw is generally based on the length of the straw. If you encounter irregular straws, you can use a soft line to surround the straw for a week. On the basis of half the length of the soft line The remaining amount can be. During the edge of the edge, we must pay attention to keeping the gap between the sealing mold and the straw uniformly to avoid leakage problems due to poor gas tightness. If the gas tightness of the alien bag is found in random testing, it should be stopped to check and re -polish the sealing mold in time. If you find that the entire edge of the alien bag is not sealed, you can compensate by adding height cloth on the unsaled side.
