FILM | ADDITIVES
In the outer layer, the masterbatch helps create a smooth and uniform surface to obtain a continuous layer of aluminum with strong adhesion. This results in fewer defects in the metal coating, which is key to achieving excellent barrier properties that meet market requirements. The positive results were confirmed by extensive trials at Bruckner Maschinenbau,” Sukano reported. The company said that packaging with a very thin aluminium coating layer is able to be composted and can be certified according to EN13432.
Enabling recycling Innovators throughout the film supply chain have been working for years to improve post-consumer film recycling and to address challenges in collec- tion, sortation, and mechanical recycling into compounds for new films and packages. One of the many challenges is creating a high enough quality post-consumer recycled (PCR) compound that can produce a good film, without gels that cause web breaks or other functional or appear- ance issues. Additives, such as stabilisers and compatibilisers, are critical to producing high-qual- ity PCR. Nexam Chemical’s Reactive Recycling viscosity- modifying additives repair degraded polymer molecules to allow the use of a higher amount of recycled content or use of lower quality feedstock without processing and production. For film applications, the additive family includes products for polymers such as polyolefins and PET. The company is seeing strong market interest from the packaging industry, particularly from blown film producers. The company recently reported that a
new blown film customer had expanded its use of Reactive Recycling additives in 2025, and that Nexam’s development pipeline in blown film has grown to over 20 companies ranging from those in early-stage testing to industrialisation. Customers have seen positive results, according
to Nexam. For example, at blown film producer Kullaplast, use of Nexamite R305 dramatically reduced bubble collapses and improved film quality when using PCR, allowing the producer to incorporate higher percentages of PCR to meet its sustainability goals. “These developments stand in stark contrast to
recent media reports portraying a struggling European recycling industry. The strong market pull we are experiencing reinforces our belief that performance-enhancing additives – used alongside conventional mechanical recycling – represent one of the most realistic, scalable and financially viable paths to circularity,” said Ronnie Törnqvist, CEO of Nexam Chemical. Nexam has a next-generation additive in development that has shown double the efficiency in laboratory testing, offering the potential to further improve customer economics and acceler- ate adoption within blown film manufacturing, the company said. “The combination of improved product perfor-
mance, better economics for our customers, and the increasing regulatory demand for recycled materials creates a very favourable environment for our technology,” said Henrik Bernquist, Business Manager at Nexam Chemical.
