Some undesirable line protrusions during the production of thick plate blister molding need to be solved by modifying the mold and adding additional pressure molds. When the cable is too large, it is regarded as defective and cannot be used for blister packaging. However, in the area of parts turnover tray, as long as the cable is arranged neatly and does not affect the use function, it should be regarded as qualified products.

The thick plate blister product, especially the transparent bubble shell, contains scratch marks. If the marks are too long and too large, the bubble shell becomes defective and cannot be used for packaging. In the production process of thick blister plate, due to the fine dust in the air, fell on the heated plastic material, a transparent defect, especially in the production process of transparent thick blister plate, this defect is too large, too much, as defective.

In the process of thick plate blister production, the heated plastic material contains air, so that the finished sheet produced with bubbles, especially in the process of transparent blister sheet production, such bubbles are too large, too much, as defective.

In the process of thick plate blister material production, due to the different materials and processing technology, the finished sheet produced surface water ripples, especially in the process of transparent thick blister material production, such water ripples are too large, too much, as defective. In general, the thicker the sheet, the more obvious the water ripple. Qualified PET materials rarely have water ripples, but most PVC have the phenomenon of water ripples.

These are common defects in thick plate blister products, which need to be prevented or solved in corresponding ways in the process of operation to make thick plate blister products meet certain quality standards.
