PET packaging for the beer market has seen a breakthrough in Germany, with Hamburg-based brewer Holsten-Brauerei AG installing a dedicated, nonreturnable beer bottle line supplied by Krones AG.
In the bastion of glass-bottled beer, some breweries had run trials, test-marketed plastic bottles or used contract bottlers abroad. But Holsten-Brauerei is the first German brewer to go the whole way and establish a dedicated PET bottling line for beer and beer-based mixed drinks, according to Krones.
The beer line, which can produce 36,000 bottles per hour, was installed in Brunswick, Germany.
Holsten-Brauerei said it is installing another PET filling line at its soft drinks and mineral water subsidiary, Hansa-Brunnen AG of Rellingen, Germany.
PET bottles are produced on Krones' Contiform S24 blow molding machine and transported by air conveyors to the PET filler Mecafill VKP-PET. The bottles are given wraparound labels and packed in shrink-wrapped trays.
Holsten will fill only half-liter bottles. Beer will be packaged in multilayer PET bottles and the containers for beer-based drinks will be made of monolayer PET, according to Neutraubling, Germany-based Krones.
