MOULD MAKING PETplanet Insider Vol. 24 No. 05/23 www.petpla.net 21 Another advantage is the minimal space requirement of the slitting technology, which, in contrast to slid warranty tapes, creates an almost imperceptible cut line. This feature greatly improves the dimensional stability and resistance of the closure during transport and during application on the filling line. Thus the closure can also be processed mostly without any adjustments on existing or new filling lines. PETplanet: What were the difficulties and technological challenges with the slitting? Büsser: Although slitting is, from our point of view, the best technology for tethering, we had to acknowledge, along with our partners, that every technology has its limitations. Fortunately, we found innovative solutions to work around these limitations. Probably the biggest task was to eliminate the strength degradation at the beginning and end of the cut. This could only be solved by a special cut design, which massively increased the notch strength at these points. The special cut design also makes it possible to optimise the strength of slitted hinged ether rings at the respective cut ends and thus save weight. This is because slit hinged ether ring closures are much more affected by this reduction in strength due to the torsional forces when the closure cap is folded down. PETplanet: In what sizes can EasyCap be produced? What is the material consumption? What features does the closure for your tethering have to have? Büsser: In principle, EasyCap tethering can be implemented on almost all closures with a folded retaining bead, provided certain design features are taken into account. The slit design has been optimised to cut as close as possible to the unfolded retaining bead without negatively affecting the subsequent folding of the retaining bead. PETplanet: In what market segment do you see particularly demand? Büsser: As already mentioned, it was particularly important to us that the consumer can drink directly from the bottle as usual, without having an annoying cap in the immediate vicinity of the face. Therefore, we see a very great potential for our EasyCap tethering in the “on the go consumption” of beverages. This is probably one of the most significant advantages of our tethering! PETplanet: Where are your forms already being used? Büsser: We already have some interested parties with whom we are in talks. Some customers have already tested the first prototypes and are convinced by our solution. In a nationwide survey, the majority of consumers were positive about our solution. PETplanet: What do you want for the future? Büsser: We would like EasyCap to be made available to consumers, through one or more global partners in Europe and around the world.
