Folding Packaging Of Vacuum Formed Foam Shells

What should be paid attention to when packaging with folded foam shells?
Folding blister packaging refers to the process where one side of a double blister is connected together during vacuum forming, and then folded to form the bottom and surface of the double blister. Its characteristic is that high-frequency edge sealing technology can be avoided, and a buckle can be made at a certain position of the bubble shell to connect the double bubble shells. If necessary, a nail needle can also be used. In terms of material selection, PET hard sheets can be used to achieve the goal of environmentally friendly materials.
Attention should be paid to the following issues:
1. Due to the lack of high-frequency machine edge sealing, the edges need to be cut with high quality on the cutting machine;
2. The tightness of the buckle should be moderate.
