Versatile and customizable designs
Cold seal technology offers extensive design possibilities, making it suitable for a broad range of products, including:
- Blisters
- Syringes
- Medical devices
Whether you require packaging for high-value medications, specialty drugs, or medical devices, our cold seal solutions can be tailored to meet your specific needs regardless of the complexity.
Enhanced patient experience
We focus on creating packaging that not only protects the product but also enhances usability. Features such as easy-open mechanisms, clear instructions, and tamper-evident solutions improve the patient experience, leading to increased adherence and better health outcomes.
Clean material separation for easy recycling
One of the key advantages of our cold seal packaging is the ability to achieve clean material separation. After use, the plastic blister and the carton layers can be easily separated, allowing both materials to be recycled efficiently.
Simplifying the packaging process of cold seal blister packs
With pressure being the only sealing parameter, the cold seal process simplifies production by:
- Reducing setup times
- Quick and easy setup minimizes downtime.
- Minimizing changeover times
- Efficient due to no cooling down or heating up time.
- Enhancing scalability
- Suitable for both small and large production runs.

Frequently asked questions
What is the difference between cold seal and heat seal blister packaging?
Heat seal uses heat to bond the pack. Cold seal uses pressure only: the blister is clamped between two layers of carton with a water-based adhesive, so no heat is needed to seal and there are no heating or cooling times in the process.
Is cold seal suitable for pharmaceutical products?
Yes. Around 90% of our pharma customers choose cold seal, for blisters, syringes and medical devices. We pack it in our GMP-licensed facility, with serialisation if required.
Is cold seal blister packaging recyclable?
The plastic blister and the carton layers are not sealed together, so after use they separate cleanly and both materials can be recycled.
Can you also supply child-resistant packaging?
Yes. For projects that need child resistance in the EU and the US, our Locked4Kids formats are certified to ISO 8317 and to F=1 under US 16 CFR 1700.20. Test details are on locked4kids.com.
Can we run cold seal packaging in-house?
Yes. We supply cold seal and heat seal packaging machines, from manual shuttle machines to fully automated inline lines, with the tooling, validation documentation and on-site installation. You can compare all models on blistermachines.com.
