The second highest complaint rate is the problem of printing on the body of the infusion bag. The content printed on the packaging materials should be clear and not easy to fade and erase. The printing material of the infusion bag is a black thermal transfer film, and the information is printed on the bag body through predetermined fonts and heating on a heating plate. To solve the problem of printing clarity, it is necessary to control the temperature of the printing heating plate and the material of the thermal transfer mold itself. Only by achieving a good combination of process parameters and materials can printing clarity be guaranteed. <br>In addition to the above two problems, the last complaint is that there is too much excess scrap. The appearance of leftovers often occurs after the bag making is completed, and the leftovers cannot be completely torn off at the edge tearing station. The possible reason is that the cutter cannot completely remove the waste edge, or the part where the waste edge is torn needs to be improved. Detailed improvement methods need to be obtained through on-site inspections.
