The screen printing principle of blister is the same as that of plastic box. The difference is that the screen printing of plastic box is one of the processes in the production process. The flat surface of the film is very suitable for printing. The significant difference of blister is here. The blister is the surface printing treatment after forming. Its 3D three-dimensional structure and the processing of silk screen bring difficulty.
No matter which type of screen printing requires positioning accuracy, blister and plastic box are no exception. The positioning of the PET plastic box is relatively simple. There are frame bars on the upper left side of the workbench, and the film can be placed directly and firmly. However, because of the three-dimensional shape of the blister, the blister after molding cannot be pressed by external forces. In this case, generally, a purely manual workbench is used for printing. The general printing process is to fix the blister with a mold, and then process printing.
The printed blister products are suitable for many occasions and multiple uses: Many masks on the market are made by blister production.
