One-way keg for breweries

Your beer deserves the best possible protection. From the moment the keg is filled, during transport and storage, and of course during dispensing. Serve your customers the quality you intended, while you’re finding new sales opportunities. The KeyKeg system will help you.


The innovative Bag-in-Keg ™ principle guarantees your beer the best possible protection. This revolutionary two-compartment system safeguards its quality and extends its shelf life by making sure it’s optimally protected from oxidation, and is never exposed to the propellant gas.  Lightweight Containers produces also a keg system with Double Wall - and Spear Technology: www.unikeg.com


Quality and safety go hand in hand with KeyKegs. The lightweight one-way kegs meet the very strictest safety requirements. The KeyKegs have the patented Double-Wall™ technology, which guarantees absolute safety. These KeyKegs are tested to 7 bar (102 psi) during manufacturing. The KeyKeg coupler is also the only system in the world fitted with a special safety valve. Clear directions on the packaging and practical instruction videos mean that everyone can work safely with KeyKegs. 


KeyKegs’ clever design and practical grip make them extremely easy to work with, and filling them is trouble-free. There are many automatic and semi-automatic filling systems available from KeyKeg-licensed manufacturers. Smaller breweries can also fill craft beers manually using the KeyKeg filling head.

The entire exterior of a KeyKeg can be custom printed with your own branding. Each one-way keg can have its own recognisable look. You’ll be directly helping to raise your own brand awareness.

Increased sales

The KeyKeg system offers much more than better quality for a lower price. The return on investment is high. Since the kegs do not have to be returned, KeyKeg is rightly called a 'sell and forget keg'. The combination of using air for dispensing, the convenient size, ease of use and safety now brings markets within your reach that were only a dream with steel kegs. What’s more, worldwide use of KeyKegs is increasing, among other reasons because the demand from hospitality outlets is growing fast.

The advantages in a nutshell:

  • Best possible quality and shelf life
  • Compatible with most filling systems
  • Efficient transport and storage
  • No more expensive return trips
  • No more ‘lost’ kegs or cleaning expenses

The environmentally friendly one-way keg

We take our environment into account, even during the design phase. A KeyKeg easily meets the environmental criteria of the European Union. Every KeyKeg is made of 30% recycled material already. The gripring and basecup are made of 100% recycled PP. Every day we strive to recycle every KeyKeg to produce new KeyKegs.
