New format, less weight
Already before the take-over, the plant was filling carbonated mineral water in 0.33 and 1.15-litre PET bottles on two lines. One of the first goals of the new proprietor family was now to replace the ailing small format by a 0.5-litre container and to fill both sizes on a single line. At the same time, the client wished to retain the design of the popular 1.15-litre customised bottle, and the paper labels as well – a rather unusual choice for PET containers. Ogeu also wanted to save weight at the preforms. So the group got in touch with Krones: the new line was supposed to be able to fill and package both formats cost-efficiently under the specified preconditions.
Initially, Ogeu was thinking of an ErgoBloc L, in which the labeller is located between the blow-moulder and the filler:
Krones is the only vendor on the market that has mastered this technology
Because of the cold-glue labelling, however, Ogeu and Krones then opted for a Contiform Bloc with a directly coupled modularised labeller downstream of the filler. “We nonetheless achieved our goal of running the wet end with just a single operator,” explains Jean-Hervé Chassaigne.
Together with the people at Krones’ container design team, moreover, Ogeu took a long hard look at the 1.15-litre container, and at the base and the neck finish reduced the weight from 34 to 30 grams. The change-over to a short-neck closure produced additional savings.
