The Difference Between Blister Packaging And Vacuum Formed Packaging

Many people who are not familiar with the packaging industry always think that blister packaging, blister boxes, and blister liners in blister packaging are similar products. However, this is not the case. So, what are the differences between these two products?

1. Double bubble shell packaging refers to a packaging form in which two bubble shells are used to package paper cards and products together. Its characteristic is that it requires a high-frequency machine to seal the edges of the double bubble shell, which is inefficient and has high packaging costs. However, the edges are neat and beautiful, and the product appearance is high-end.

2. Card suction packaging refers to the heat sealing of blister packs onto the surface of paper cards with vacuum formed oil, which is commonly used in supermarket battery packaging. Its characteristic is that it requires vacuum sealing equipment to encapsulate the product between the paper card and the blister.

The issues to be noted are:
The blister can only be made of PVC and PETG film, otherwise it cannot be heat sealed or the heat sealing effect is poor;
The quality of the edge of the double bubble shell is determined by the quality of the high-frequency mold.
Blister packaging is a commonly used type of packaging that uses the vacuum forming process to produce plastic products and uses corresponding equipment to package the products. The blister packaging box sheet is heated at high temperature, vacuum sucked, and cooled to form a plastic box shape. It can be molded by heating according to the shape of the product. The use of vacuum packaging is more extensive! And for me, the process is not that complicated!
