The reasons for the defective blister packaging box are nothing more than the following points, such as uneven thickness, pull lines, crystal dots, water lines or bubbles. Analysis of the causes of bad blister packaging boxes and management methods for how to solve them.
1. There are three main reasons for the uneven thickness of the blister packaging box.
①The problem of the shelf, that is, when you load the material on the machine, the adjustment of the position is very important. Once the company has some irregular or misplaced placement, it will cause the thickness of the blister box to be uneven. . Need to improve the position we should pay attention to when we put it on the shelf.
②The thickness of the sheet is not adjusted properly during the manufacturing process, which may cause uneven thickness. This requires a high-quality sheet supplier.
③The temperature changes are related. Different materials require different temperatures. Assuming that the ambient temperature is not adjusted to the appropriate temperature, it is easy to make the thickness of the blister packaging box uneven.
2. There are pull lines on the blister box. The reason for the pulling line is mainly related to the rationality and quality and safety of the industrial structure of the blister mold, and to a certain extent, it is also related to the operation of the blister machine and the selection of materials when putting it on the shelf. The solution is to find a high-quality blister mold manufacturer to establish a cooperation, and just notice a little bit when the materials are put on the shelf and the machine is adjusted.
3. There are crystal dots on the blister packaging box. On the one hand, materials with poor quality were selected, and on the other hand, impurities were mixed into the sheet. The solution requires a certain amount of sampling inspection, contacting the sheet supplier to replace the sheet.
Fourth, there are water ripples or bubbles on the blister box. The cause of water ripples has a lot to do with the molding speed of the blister box. The air bubbles are more likely to be caused by the poor quality of the sheet material and the infiltration of a large amount of air pollution during the production process. To solve this method, one is to pay attention to the internal control of the time of blister forming, and the second stage is to pay attention to the quality of the sheet.
