Keystone Resealing Bung

Built in Burton. Trusted Across the Brewing Industry.

UB Plastics was founded in 1983 to supply plastic injection moulded components to the brewing sector – replacing traditional wooden parts with modern, hygienic alternatives. From day one, the company has served breweries across the UK from its base in Burton upon Trent, a town synonymous with beer production. Over four decades later, we continue to manufacture millions of brewing-related components every year, combining our heritage with modern automation and quality systems.

We’ve grown alongside the brewing industry, working with global brands and local independents alike. Our team understands the technical, logistical and seasonal demands that breweries face, and we’ve built our processes to meet them reliably.

Supporting Brewers Across the UK and Beyond

The brewing sector is one of the UK’s most established and diverse manufacturing markets. From multinational producers to regional cask brewers, the need for safe, hygienic, and traceable packaging and dispensing components remains constant.

We work with breweries of all sizes, from long-standing household names to new craft entrants, supplying core packaging components and helping them streamline operations, reduce waste, and meet compliance needs. Our products are used daily in kegging, cask conditioning, storage and distribution.
