Key-keg facts


Lightweight Containers

Lightweight Containers BV is the originator of the innovative KeyKeg system. Our unique lightweight KeyKegs combine ground-breaking R&D, advanced production technology and a clear idea of what our customers want. The result is a range of one-way kegs that stand out in the market for their quality, convenience, safety and sustainability.

The environmentally friendly one-way keg

We take our environment into account, even during the design phase. A KeyKeg more than meets European Union environmental criteria. The KeyKeg Slimline will eventually be made from over 50% recycled PET, and our goal is to recycle every KeyKeg to produce new KeyKegs.

The Best Possible Protection

Quality First

The KeyKeg system’s innovative design is based on years of research and practical experience. It is reflected directly in the quality of the beer, wine, cider or soft drinks in our lightweight PET kegs. With the KeyKeg system, quality and safety go hand in hand over the entire supply chain, from filling and transport to dispensing and serving to consumers. These feature are why KeyKegs will replace more and more steel kegs in the future, and there’s no going back. Over 800 customers worldwide have made the switch to KeyKegs, and the KeyKeg system is in use in over 180 countries.

The convenient format and handy grip ensure that everyone can start working with KeyKegs right away. The kegs are also lightweight and easy to stack, so the KeyKeg system saves valuable space during storage and transport. Everyone in the chain enjoys these advantages – producers, distributors, restaurants and bars and consumers.

Revolutionary Technology

Ultimate Design

Innovations from our own R&D lab are the foundation of the KeyKeg system. The patented Bag-in-Ball principle is based on a specially developed laminated inner bag inside a high-tech PET container. This two-compartment system safeguards the quality and shelf life of the beverages in KeyKegs. Our kegs give beverages optimal protection from exposure to oxygen, and they are also never exposed to the propellant gas, which greatly extends their shelf life.


KeyKegs meet the strictest safety requirements. The kegs are tested in-line during manufacturing. The Double Wall technology in the Slimline series ensures maximum safety during shipping, transport and dispensing. KeyKegs also have a specially designed safety valve op the coupler. These features, plus the clear directions on the packaging and on-line instruction videos, mean that everyone can work safely with the KeyKeg system.
