Blister Card Mounting & Professional Heat Sealing
Precision Assembly for Retail-Ready Packaging.
While our name reflects our deep roots in the plastics industry, Blisters Ltd has evolved. We have retired our in-house thermoforming machines to focus entirely on what we do best: high-precision blister card mounting, heat sealing, and contract assembly.
By specialising exclusively in the assembly stage, we provide a superior, tamper-evident bond and a professional finish for your pre-formed blisters, perfectly tailored for bespoke brands requiring small-batch agility right up to high-volume production runs.

Our Seamless Assembly Process
Getting your product retail-ready is a simple collaboration. We take your supplied components and turn them into a finished, professional package.
Precision Mounting & Sealing
Using our specialised heat-sealing equipment, we align your product and plastic housing perfectly to the card. We manage the exact temperature and pressure to ensure a secure, tamper-evident bond every time.
Agility & Scale
We champion a tailored approach. Whether running bespoke assembly lines for small, initial batches or seamlessly scaling up to runs of tens of thousands of units, our focus is always on flawless quality and absolute reliability.
Component Collaboration
You provide the pre-formed plastic blisters and custom-printed cards. While we focus entirely on the assembly and seal, we can also connect you with our trusted print partners for your backing cards.
Final Quality Check
Every single unit is visually inspected for seal integrity, alignment, and clarity, operating strictly under our BRCGS AA accredited standards. Once approved, we pack your finished cards into outer cases, ready to hit the retail shelves or distribution centres.
Decades of Packaging Excellence
With roots stretching back to 1985, our portfolio is vast. The legacy gallery below demonstrates our deep understanding of what makes a successful, retail-ready blister pack across multiple industries. (Click to enlarge)
