Double blister packaging refers to a package that encloses a paper card with a product in two blister packs. It is characterized by the need for a high-frequency machine to seal the double blister, low efficiency, high packaging cost, but the edges are neat and beautiful, and the appearance of the product is high-grade.
The problems that should be noted are: 1. The blister can only use PVC and PETG film, otherwise the heat sealing or heat sealing effect is not good; 2. The quality of the high frequency mold determines the quality of the double blister edge.
