Cosmetic Slide Blister Packaging

Slide Blister Packaging


Sliding card blister refers to a packaging form in which a paper card and a transparent blister folded over three sides are inserted together. Its characteristic is that it does not require any packaging equipment during packaging, and only requires workers to put the product, blister and paper card in place That's it.


The issues that should be noted are:

1. The size of the paper card and the folded blister is appropriate. If they are inserted too tightly, the paper card and the blister will be deformed; if they are too loose, they will be easily separated.

2. When the product is too heavy, consider fixing the paper card and the blister at a certain position with staples.
