Pvc film is used in interior decoration and furniture manufacturing industry.
The production process of PVC blister film is more detailed, let's talk about its production process next.
1. First of all, let me introduce the mold making process: we need to make plastic molds in advance according to the corresponding specifications. The commonly used material is plaster, which is used to make plastic packaging molds. In addition, there are wood carving and metal carving products.

According to the distribution of the plaster surface, use 1~2mm drills and drill some small holes in the low recesses. If it is like a packaging box, you can also It is necessary to drill some small holes around the periphery, so that the air can be drawn out as soon as possible during blister production. The next step is to harden the plaster mold, which can be soaked in concentrated alum saturated solution and then dried.
2.

3. After heating, put it in the vacuum chamber, and then we will turn on the suction switch. This is mainly to suck the air in the vacuum chamber. craft mold.
4. The last step is to carry out blister packaging. We need to trim and arrange the produced blister film, and then pack it before it can flow into the market.
