Triple Fold Packaging Of Vacuum Formed Foam Shells

What should be paid attention to when packaging with three fold foam shells?
Triple fold blister packaging is the process of folding the blister into three sides (front, bottom, and back), creating an additional bottom edge so that the product can stand on a flat surface. 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 bubble shell. If necessary, a nail needle can also be used. In terms of material selection, PET hard sheets can be used to achieve the purpose of environmentally friendly materials, which is suitable for packaging large-diameter products.
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.
