Introduction
Plastic blister packaging—also called thermoformed packaging or vacuum forming packaging—is one of the most versatile, widely used packaging solutions across global industries. From chocolate trays and bakery containers to electronics clamshells and retail display packs, blister packaging combines visibility, protection, affordability, and customization in one streamlined format.
What Is Plastic Blister Packaging?
Blister packaging is a thermoforming process that heats plastic sheets until flexible, then vacuum-forms them onto a custom mold to create precise cavities, trays, inserts, or shells. After cooling and trimming, the packaging holds its shape, creating a form-fitting, protective holder for products.
Common types include:
Blister trays / inner inserts
Clamshell blister packs
Lid-attached blister boxes
Custom cavity trays
Its greatest strength: perfect product fit + full visual display.
