2020-05-19 864

Double blister packaging refers to a packaging form that uses two blister packages to encapsulate the paper card and the product. Its characteristic is that high frequency machine is needed to seal the double-bubble shell, the efficiency is low, the packaging cost is higher, but the edges are neat and beautiful, and the product appearance is high-grade. The issues that should be noted are: 1. The bubble shell can only use PVC and PETG film, otherwise it cannot be heat sealed or the heat sealing effect is not good; 2. The quality of the high frequency mold determines the quality of the double bubble shell edge.
