Czech company, Petainer Group, has entered into a partnership with two Japanese companies KHS Japan and Mitsubishi Chemical to bring one-way PET beer kegs to the Japanese beer market.
The packaging technology group said the partnership was in light of a boom in craft beer in Japan; a boom which has also seen leading Japanese brands, such as Asahi and Kirin, garner increasing international recognition.
The collaboration includes the development of a new 10L keg, specifically designed for the Japanese market.
The keg will support the Japanese legislative trends, which call for reducing packaging weight limits.
The process will involve using Mitsubishi’s DLC (diamond like carbon) high gas barrier technology, which will replace PetainerKeg’s existing nylon and polyshield barrier technology.
DLC is also clear as opposed to the traditional amber.
Eliminating nylon and colour ensures that the keg is recyclable as part of the Japanese recycling stream.
Mitsubishi already uses DLC for some of its existing product ranges which it provides to the alcoholic drinks industry, including global brands such as Kirin.
“We have combined our proprietary technology with Petainer’s product to produce the DLC Keg which is perfectly tailored to the Japanese market,” said Yosuke Egawa, senior associate director at Mitsubishi, commenting on the partnership.
Single-use PET kegs are increasingly being used as a more economical and efficient alternative to traditional steel kegs and glass bottles by brewers around the world.
They are recyclable, cutting out costly return logistics and washing processes.
