Interpack 2014: Efficient production of portion packs

MULTIVAC. Since the packaging machine manufacturer has designed a slower packaging procedure, this can easily be controlled even at a high output. This has a positive effect on the upstream and downstream processes such as filling, cutting, quality control, pack handling and secondary packaging in boxes.

MULTIVAC's head start in expertise as regards die technology and automation gives manufacturers of portion packs many benefits: Firstly, they can achieve a maximum output from their thermoforming packaging line, since the plus factor in the process control is not gained at the expense of the number of packs produced.

Secondly, the use of MULTIVAC's innovative cutting technology leads to a reduction in packaging material consumption. "In order to cut the large number of packs cleanly out of the film, we position two cutting tools one after the other. These cut the portion packs out of the film in two stages, similar to the pattern of a chess board," explains Mr Heinrich. Since not all the packs are cut out at once, the partitions between the packs can be designed to be narrower than with conventional die processes. Thanks to the reduction in the widths of the partitions, manufacturers of portion packs can save a not insignificant amount of packaging material. This also makes the investment in this cutting procedure economically viable.

Thirdly, the easily controlled cutting procedure has a positive effect on the handling of the portion packs after cutting. Since "only" half the packs must be removed per cutting tool, the removal from each cutting tool and the transfer of the packs to downstream processes, such as secondary packaging in boxes or quality inspection, can be performed in a very controlled manner. In this way MULTIVAC technology ensures that maximum process reliability and pack quality are achieved.

Interpack 2014, a leading fair in processes and packaging, will be held on 8-14 May 2014 at Dusseldorf, Germany.
