The K-SWE-HD/RS is specifically suitable for processing polyolefin recyclates in blown film applications. It allows for maximum process stability resulting in significantly reduced downtime. Its high automation degree allows for minimum operator intervention and maximum safety.

Producing quality blown film is not an easy task. A film bubble reacts sensitively to changing process conditions, and only minor changes in temperature, viscosity, and especially pressure can have a negative impact. Existing filters provide the necessary process stability and deliver clean, homogenous melt for a high-quality blown film – when only virgin material is used.

But this won't be the case much longer. The social call for more sustainability in the plastics industry has led to new laws and regulations. Producers face tax penalties and other consequences if they don't increase their use of recycled material significantly. But adding recycled materials to the mix is an additional disruptor to an already delicate process. Depending on their size, contaminants can cause optical flaws and bubble ruptures, leading to line shutdowns.

"The change from using only virgin materials to including recycled material is huge and needs new, innovative technology to support that transition. But we like a challenge," says Christian Schroeder, Global Segment Manager for the recycling market at Nordson. " We developed a melt filter, based on our unique backflush technology, that enables the use of recycled material while keeping the process stable and the end product quality at the usual high level.
