A lot of people who do not know much about the packaging industry, always think that the blister case and the blister box in the blister package, the blister intro these are the same kind of products, in fact, not so much, so what are the differences between these two products?

1. Double bubble shell packaging refers to the packaging form that USES two bubble shells to package the paper card together with the product. It is characterized by the need of high cycle machine to seal the edge of double bubble shell, low efficiency, high packaging cost, but neat and beautiful edges, and high product appearance.

2. Blister packaging means to heat the blister shell to the surface of the paper card with plastic oil, which is commonly used in the battery packaging of supermarkets. It is characterized by the need of blister sealing device to encapsulate the product between the paper card and bubble shell.

The issues to be noted are:

1. The bubble shell can only be made of PVC and PETG film; otherwise, it can't be heated or has a poor thermal effect;

2. The quality of high frequency die determines the quality of the edge of double bubble shell.

Blister packaging is commonly used in packaging, plastic products produced by the process of blister, and the general term of packaging products with corresponding equipment. The plastic packaging box sheet is heated at high temperature and then vacuumed and cooled to form a plastic box. The product can be shaped by heating. Blister packaging more extensive use! And the process is not that complicated!
