In addition to the problem of product leakage, the second highest complaint rate is the printing problem of the infusion bag body. The content of the printing or molding on the packaging material should be clear and not easy Fades and erases. The printing material of the infusion bag is a black thermal transfer film, and the information is printed on the bag body through the predetermined font and heating with a heating plate. To solve the problem of printing clarity, the temperature of the printing heating plate and the material itself of the thermal transfer mold should be controlled. Only by realizing a good combination of process parameters and materials can the printing clarity be guaranteed.In addition to the above two problems, the last complaint is relatively small but should be resolved, that is, the leftovers of the infusion bag. The appearance of the leftovers often occurs after the bag making is completed, and the leftovers cannot be completely torn at the edge tearing station. The possible reason is that the cutter cannot completely remove the waste edge, or the parts that tear the waste edge should be improved. Detailed improvement methods can only be obtained after on-site actual investigation.
