Sealed Blister — Tamper-Evident Heat Seal
Heat-sealed blister packaging — transparent hood permanently sealed to a card backing. Maximum product security and tamper protection.
What is a Sealed Blister?
A sealed blister consists of a thermoformed transparent hood heat-sealed to a printed card. Once sealed, the package cannot be reopened without visibly destroying it — making it the gold standard for tamper-evident retail packaging.
Ideal for consumer electronics, hardware, batteries, cosmetics and pharmaceutical OTC products. The card carries your branding, instructions and barcode while the clear hood showcases the product.
We supply matching coated cards and the thermoformed hoods, fully tooled to your product geometry — from 5,000 pcs.
