Krones Kosme 3Bloc packaging system

The Krones 3Bloc comprises a blow-moulder/unscrambler, filler and labeller, and is available in variants for PET and HDPE containers.

The PET version comprises three concatenated machines: blow-moulder, filler and labeller. The particular version of the Flexa labeller can vary, either featuring pressure-sensitive labelling with a Flexa Sensicol station or wraparound labelling with a roll-feed capability. This version is suitable both for cylindrical and square PET bottles and also for containers with special shapes. The maximum speed is 16,000 bottles/h.

In the case of HDPE containers, the blow-moulder is replaced by an unscrambler for erecting them as they are fed in. This variant is able to handle up to 25,000 bottles/h.

The system offers significantly reduced energy consumption compared to individual machines, as well as higher efficiency and enhanced operator-friendliness. The block configuration benefits the footprint of the machinery layout, as well as capital investment and operating costs. Intermediate conveyors are no longer needed, and the times required for changeovers and maintenance work are shortened.
