PETINAR PETplanet Insider Vol. 23 No. 12/22 www.petpla.net 20 Review on the PETinar series Technical Highlights at Drinktec 2022, day 2 PETINAR Sponsors Ueli Kobel, International Sales Manager, Product Manager Beverage & Specialties Division at PackSys Global, also fulfilled audience expectations and presented the new efficient and highly precise folding and cutting machines for the production of plastic closures. As part of the Brückner Group, Packsys Global has more than 300 employees and customers in 90 countries worldwide. Headquartered in Switzerland, Packsys Global currently has more than 500 machines on the plastic closure market. Ueli explained that all closure machines can be adapted for conventional or different types of tethered closures and that capLAB - the first inline system for quality testing of closures - can be used to comprehensively inspect tethered closures. To serve the tethered closure market, Packsys Global has developed three technologies: the smarTether, experTether and the CapCompass. SmarTether is a technology with a combination of various cutting segments to create perforation lines for the TE band and the tether function. This can be simple horizontal cutting, or it can be combined with multiple vertical or diagonal slit lines. smarTether purposely leaves a thin and controllable skin in defined sections of the separation lines. It supports during the capping process and will easily break at the first opening. Ueli states that smarTether can be applied on all existing major PET bottle closure applications. The technology delivers a high-performance tethered closure suitable for highspeed capping processes. The experTether is for lightweight plastic closures which require perfect and continuous support on both blades of the knives during the slitting process. ExperTether and smarTether can both be used for the same cutting line pattern. With experTether the entire slit contour is 100% cut through – including the vertical and diagonal section. This is done by the synchronisation of the rotating spindles to the fixed slitting knives. Independent of the machine speed, the synchronised inner and outer tooling provide unique slit accuracy for customised slitting patterns for the tethered feature. Both the TE band and the tethered feature are processed using the same mechanical cutting technology. CapCompass is the method to bring a closure, when first opened, to a position which is locked and does not disturb the consumer while drinking. Gable top or other carton packaging applications are major markets for this processing method. Whether it’s a pre-moulded hinge, a thread start, an embossing, or some other feature, the slit lines can be positioned for functionality and/or marketing purposes. CapCompass is made for cutting closures at the right place and could be combined with smarTether or experTether additionally to TE Band slitting. At Drinktec PackSys Global also presented its new TEM Plus, Ueli continued. This versatile machine is integrated into any production line due to independent control and optional vision inspection system. The TEM gives flexibility in the process sequence thanks to its modular design for S/F or F/S of TE band. It also allows a large variety of cap dimensions, including sport caps. Contour slitting and synchronised cutting enable tethered applications. The nominal diameter range is from 18mm to 90mm. Closures from 10mm to 48mm high can be processed at a speed of 800 ppm for heights up to 48mm and 1,000 ppm for heights up to 27mm, Ueli summarised. www.packsysglobal.com After this comprehensive insight into PackSys Global’s slitting and folding technology, Iacopo Bianconcini, Manager Marketing and Product Development at Sacmi, took over the microphone. He posed the question of how the digitalisation of closure manufacturing could be translated into a real economic advantage. Iacopo gave a brief introduction to Sacmi: with 4,720 employees worldwide Sacmi has a net worth turnover of more than €1,5 billion, with 86% being exported. It has 80 companies worldwide of which 10 are manufacturing facilities. He pointed out that Sacmi develops multi-material packaging solutions for the most diverse platforms, to meet the needs of beverages and food producers all over the globe. In so doing, Iacopo stated that Sacmi is at the forefront of the global transition to a circular economy in the packaging field. This is achieved using the 3Rs approach; Reduction, Expectations were again high on the second day of the PETinar series: the presentations by PackSys Global, Sacmi and Stack Teck were eagerly awaited. After the first day with presentations from z-moulds, who presented smaller, adapted mould sizes for the production of closures on smaller machine types, or the new high-quality tethered caps from Bericap, as well as the presentation of the new PAC-E machine generation from Sumitomo (SHI) Demag, the standard was high!
