Key Features
Custom Trapped Blister Packs | Clean-Edge Blister Packaging Between Two Cards
Trapped blister packs sandwich the thermoformed blister between two printed paperboard cards — the front card has a die-cut window with the blister cavity protruding through it, while the back card seals the package from behind, trapping the blister and product between both cards. No plastic edges are exposed at the card perimeter, giving trapped blisters a cleaner, more premium appearance than standard face seal blisters.
Construction
The front card has a die-cut opening sized to the blister's outer dimensions. The thermoformed blister inserts through this opening from the front, with the blister flange resting against the back face of the front card. The back card is glued or heat-sealed over it, sandwiching the blister flange securely. Product is accessed by separating the two cards.
Advantages
- Clean edges — no exposed plastic at card perimeter for premium appearance
- Full back panel — complete back card surface available for printing
- Strong construction — trapped flange is more secure than face seal bonding
- Easy assembly — blister drops into front card, back card applied over it
The Premium Appearance Advantage of Custom Trapped Blisters
The defining visual characteristic of trapped blister packs is their clean edge — no plastic extends beyond the card perimeter, giving the package the neat professional appearance of a printed card rather than the industrial look of face seal blisters with visible plastic flanges. This cleaner presentation makes trapped blisters the preferred format for gift items, toy collector packaging, and specialty products where retail appearance quality communicates product quality.
Full Back Panel: Double the Print Surface
Because the back card is a complete unattached printed panel, trapped blister packs offer the maximum print surface of any blister format — complete front card printing plus complete back card printing with no area consumed by blister sealing. This double-panel surface is particularly valuable for products with extensive regulatory labeling, product comparison charts, or brand storytelling requiring more space than a single card provides.

Trapped Blister Packs in Daly City — FAQs
What is a custom trapped blister pack?
A trapped blister pack sandwiches the thermoformed blister between two printed paperboard cards — the blister inserts through a die-cut opening in the front card, and the back card is applied over the front card's back face, trapping the blister flange between them. No plastic is visible at the package edges.
How does a trapped blister differ from a face seal blister?
In face seal blisters, the plastic flange is sealed to the front face of a single card with edges visible at the perimeter. In trapped blisters, the plastic inserts through a die-cut opening and the flange is trapped between two cards — no plastic is visible at the edges. Trapped blisters appear cleaner and more premium; face seal is more economical for high volume.
What products are best suited for custom trapped blisters?
Trapped blisters are preferred for gift items, toy collector packaging, specialty craft products, and any application where retail appearance quality matters. The clean edges and full back panel print surface make trapped blisters effective for premium retail positioning.
How are custom trapped blisters opened by consumers?
Trapped blisters are opened by separating the front and back cards — typically by peeling or tearing the card bond at the package edge. Some configurations use perforated tear strips that guide the opening process.
