Netstal presents a lightweight ICM thin-wall cup made of 100 % PP
Netstal will produce thin-wall packaging optimized for the circular economy using injection compression molding. Another highlight is the new Axos 9 control generation.
It’s light as a feather, the yogurt cup Netstal presents at Fakuma. The other vital data: Filling volume 200 g, part weight 5.4 g, wall thickness 0.3 mm. Since the cup and label are made of 100 % polypropylene (PP), the packaging is straightforward to recycle. Unlike a conventional in-mold label, the label comes off in the mechanical recycling. The PP stream is unaffected because printing ink particles are reliably separated from the pure PP. Injection Compression Molding (ICM) reduces the cup’s weight by 34 %. Another improvement in terms of sustainability: the combination of the ICM process and product optimization also results in a 27 % reduction in packaging volume.
Sustainable cup, energy-efficiently produced
The sustainable thin-wall packaging for dairy products is produced in 4 cavities at a cycle time of 2.7 seconds in an Elion 1750 with a hybrid injection unit. The Netstal machine operates with reliable performance and leading energy efficiency. With the optionally available adaptive system pressure reduction, Netstal has further optimized its hybrid machines’ efficiency. In automatic mode, the control system determines the optimum point at any time and adjusts the pressure in the hydraulic system accordingly. Depending on the application, the energy consumption for providing the required system pressure drops to a minimum.
Optimized for recycling, the packaging application was developed with high-end system partners Glaroform, Beck Automation, SABIC, IPB Printing, motan, Regloplas, and Uniform Color. The development partner from the food industry is Emmi AG, the largest bottler of dairy products. The packaging specifications were optimized with and under the guidance of Emmi’s requirements. In the process, the previous appearance of the cup was to be retained.
Operate the machine intuitively with the new Axos control system.
With Axos 9, Netstal is bringing the latest generation of its control technology to the Elion and Elios series machines. Thanks to the innovative operating concept, users get the maximum performance from their Netstal machine. Thanks to the integration of Smart Operation, employees in the production environment operate the machines quickly, safely, and effectively. The feature was previously available as a paid option and is included in the scope of delivery from Axos 9.
