Hot runner systems in action Oerlikon HRS Flow presented the evolution towards fully recyclable packaging at K
Intricate applications of Oerlikon HRS Flow hot runner systems produced in cooperation with project partners were presented at the K Show in Düsseldorf, Germany. The live moulding demonstrations included a thin-walled 150 ml IML Yogurt cup.
At the booth of Oerlikon HRS Flow’s project partner Netstal at K, the Elios 4500 Injection Moulding Machine produced a thin-walled 150 ml IML yogurt cup (6.4 g) from a certified renewable PP polymer by Sabic, highlighting the importance of human and environmental health. The material is based on tall oil, a waste product from paper production. The powerful and energy efficient Netstal injection moulding machine compensates for the slightly thicker label in the injection moulding process with a correspondingly thinner wall thickness of the cup. Wall thickness of the 5.4 g cup without label measures only 0.32 mm. This high-performance application runs with a fast 3,9 s cycle time.
The new Xp nozzle Series from Oerlikon HRS Flow, specifically engineered for thin wall packaging, ensures a reliable process and an increased productivity at the lowest cost per unit. The result is a low thickness component (0.4 mm) injected with ambitious cycle times and decorated with a new generation label: the Nextcycle IML from MCC Verstraete. The Nextcycle IML labels allow that a fully decorated PP IML package can be recycled without any impact of the label on the RPP material. These labels will also feature digital watermarks from the Holy Grail 2.0 initiative. The project was developed in cooperation with Netstal, IML Solutions, MCC Verstraete, Sabic, Oerlikon HRS Flow.
