UB Plastics Ltd

UB Plastics’ tamper-evident caps are relied upon by breweries and keg suppliers across the UK and internationally to maintain product integrity and enable full traceability throughout the supply chain. Compatible with all standard keg spear types, the caps feature a clear visual seal that instantly indicates whether a container has been opened or tampered with prior to use.

Manufactured from robust, food-grade polypropylene, each cap incorporates a tear-off strip for visible tamper evidence and supports up to five-colour custom branding via high-speed in-mould labelling (IML). Offered in three sizes and a broad selection of colours, the caps are produced using either virgin or 100% recycled plastic. They can be fitted manually or with automated equipment and are fully recyclable at end of use.

UB Plastics’ two-piece shives provide a dependable sealing solution for stainless steel and select plastic casks used throughout the brewing industry. Each shive features a tough LLDPE body paired with a flexible EVA sealing band, delivering a secure fit while enabling controlled venting during dispense or conditioning.

Produced at our Burton-upon-Trent facility using high-volume moulding technology, the shives are offered in two standard sizes and a variety of colours, with optional printing available for batch tracking or custom branding. Made exclusively from virgin materials and carefully packaged for protection, they offer brewers a reliable, high-quality solution with proven performance.

UB Plastics’ injection-moulded pegs are purpose-built for resealing casks and kegs once the shive has been broached. Made from robust high-density polyethylene (HDPE), they ensure a tight, dependable seal that helps maintain product freshness, prevent leaks, and minimise oxygen ingress.

Manufactured in high volumes at our Burton-upon-Trent facility, each peg is precision-engineered for uniform fit and performance across every production run. Supplied in bulk, they provide brewers of all scales with a cost-effective and reliable sealing solution.

UB Plastics’ keystones are a proven sealing component for traditional cask-conditioning systems. Crafted from durable, food-grade thermoplastic elastomer, they deliver a secure, hygienic seal while allowing straightforward one-piece removal, either manually or with automated extraction equipment.

Engineered to withstand the temperature and pressure demands of commercial cask-washing cycles, our keystones are offered in both standard and “tutted” designs to accommodate different handling preferences. Available in a wide range of colours, they also support clear product identification and consistent branding across your cask fleet.

UB Plastics’ keystone bungs are precisely engineered to complement our keystones, offering brewers a practical, efficient solution for resealing casks after tapping and a reliable alternative to traditional cork bungs.

Designed for one-piece removal together with the keystone, the bungs streamline handling and simplify post-use cask processing. Manufactured at our Burton-upon-Trent facility using high-volume moulding technology, they ensure consistent fit, dependable performance, and suitability for breweries of every scale.
