Our kegs, called KeyKegs, are state of the art, one-way keg which the vendor simply disposes of in the recycling after use. The KeyKeg is designed according to the bag-in-ball principle. The pressurized PET ball houses a specially developed flexible inner bag, which contains the beer. The content is dispensed by pressurizing the space between the bag and the ball. No CO2 or air will therefore make contact with the beer. The ball itself has been designed to withstand the anticipated internal pressures, as well as abusive handling throughout the supply chain.
The inner bag has a special evacuation strip which, together with the constant overpressure on the bag, ensures that the content is dispensed right down to the last drop of beer. The specially designed inner bag is odorless and tasteless and has superior barrier qualities. This allows dispensing beer using air instead of CO2 and, once the KeyKeg is broached and dispensed from, the beer will stay fresh in the keg for many weeks. When emptied, KeyKeg can be deflated by a special tool and once the air has escaped, the empty keg takes up little or no space, so small outlets can use their storage space for full kegs only and put the emptied KeyKeg out with their recycling.
