Introduction to Blister Trays


Amidst the myriad packaging solutions in today's market, there's one that strikes an impeccable balance between protection and presentation: the blister tray. Recognizable by its clear plastic shell and snug fit around products, blister trays are more than just a functional item; they're a packaging strategy that optimizes visibility, accessibility, and security.


Basics of Blister Packaging

Commonly known as 'blister trays' or 'blister packs', this form of packaging is characterized by its unique design. The main component is a pre-formed plastic cavity designed to hold the product securely. This cavity is meticulously designed to match the shape and size of the product, providing a glove-like fit. Partnered with this is a backing, which could be a card, an aluminum sheet, or even another piece of plastic. Together, they create a sort of "clamshell" effect, with the product comfortably nestled inside, visible yet protected. The design is such that the product remains clearly visible, ideal for retail displays where customers appreciate a clear view of their potential purchase. Yet, the robust design ensures the product within is shielded from external contaminants, damage, and tampering.
