Eliminating the “Smile” with Bottle Lock Technology
A common challenge in shrink sleeving is the “smile” or “frown” effect—where the bottom edge of the sleeve curves unevenly during the heating process, distorting the artwork. We solve this issue at the engineering level using our specialised Bottle Lock Steam Tunnels, ensuring your graphics are always crisp and perfectly aligned.
Targeted Steam & The Base Lock
Rather than applying uniform heat immediately, our system precisely directs steam to the lower ridge of your container first. This initial, targeted heat instantly anchors the sleeve to the base of the container, preventing any upward movement or curling.

Distortion-Free Shrinking
Once the base is locked securely in place, the sleeve shrinks evenly and symmetrically across the contours of the bottle as it moves through the rest of the tunnel. The result is a flawless, premium finish that protects your brand’s visual identity.

The Human Edge: Engineering & Planning
We know that in manufacturing, challenges always arise. That is why our true strength lies in our ability to problem-solve. Our in-house engineering team is continuously adapting and tweaking our equipment to overcome tricky packaging requirements, while our meticulous planning team builds schedules that can actually absorb the unexpected. We don’t rely purely on the machines; we rely on a fantastic team to ensure your production keeps moving, even when other high-volume plants face downtime.
High-Volume Capacity & Specialised Capabilities
Supply chain reliability is just as important as visual quality. Our UK production lines are designed to handle complex requirements seamlessly, providing you with a fully outsourced, stress-free sleeving process.
Scalable High-Speed Production
Depending on the specific material (glass, plastic, or aluminium) and the shape of your container, our automated lines can seamlessly scale to process up to 5,000 products per hour. With the flexibility to run up to 15 hours of production a day, we have the agility and sheer volume capacity to meet your most demanding deadlines.

Automated Multi-Packs
Blisters’ automated shrink sleeve applicators offer highly specialised capabilities. We provide the advanced ability to apply multi-pack bands (such as twin and three-packs) fully automatically. This significantly reduces manual handling, making us highly competitive on price, flexibility, and turnaround capacity.

Dual Process Automation
Our facility is designed with agility in mind. We operate with adaptable, movable machines, meaning our processes are like a jigsaw where the pieces can adapt to fit together seamlessly. All under one roof, we can shrink sleeve your product and immediately transfer it to a machine capable of turning them into a multipack. This saves you multiple handling costs. Everything is fully logged via our hand-crafted traceability system, operating securely under BRCGS AA conditions.

Certified Quality & Compliance
We operate to strict BRC standards with fully computerised batch recording for complete traceability. Beyond standard compliance, we are authorised to handle goods Under Bond and hold Soil Association accreditation, making us the ideal nationwide partner for organic brands and duty-suspended products.
