The principle application of blister packaging

Blister packaging is a packaging method in which a product is sealed between a blister formed from a transparent plastic sheet and a base plate (made of cardboard, plastic film or sheet, aluminium foil or their composites).

Since this packaging method is based on the substrate, it is also called substrate packaging. The package made of blister packaging has a transparent appearance on the one hand, and the appearance of the product can be clearly seen; at the same time, the substrate can be printed with exquisite patterns and instructions for use of the product, which is convenient for display and use. On the other hand, the packaged product is fixed between the formed blister and the substrate, which is not easy to be damaged during transportation and sales. It can not only protect the product, prolong the storage period, but also promote the product and expand the sales.

Blister packs were originally primarily used for pharmaceutical packaging. Now in addition to the packaging of pharmaceutical tablets, capsules, suppositories and other pharmaceutical products, blister packaging is also widely used in the sales packaging of food, cosmetics, stationery, toys, gifts, tools and mechanical and electrical parts.
