Enable higher use of PCR in LDPE and LLDPE blown film without process instability, film breaks, or quality loss.

Nexam Chemical’s Reactive Recycling™ technology repairs the recycled polymer and restores melt strength during processing, making even challenging PCR streams usable.

Example results show that adding ~2.5% masterbatch enables stable blown film production where it was previously not possible.

Using recycled LDPE and LLDPE in blown film often leads to:

• Low melt strength causing unstable bubbles
• Frequent film breaks and production stops
• Poor thickness control and inconsistent film properties
• Gels and contamination issues

This limits PCR usage, often below 30–50%, and increases waste and downtime.

Reactive Recycling™ technology restores polymer structure directly in the film production process with no additional equipment needed.

By adding a functional masterbatch during processing:

• Polymer chains are rebuilt
• Melt strength is increased
• Process stability is significantly improved

The additive fully reacts and integrates into the material, enabling consistent production even with challenging recycled streams.

• Increase PCR content without losing process stability
• Enables use of lower-grade and variable PCR streams
• Improved bubble stability, fewer film breaks, and higher uptime
• No need for upgauging due to poor PCR material
• Higher line speeds possible due to improved melt strength
• Helps manage HDPE/PP contamination via partial compatibilization
• Can reduce gels depending on material

Without additives, high PCR content materials may not be processable.

With Reactive Recycling™, Nexamite™ R305, and the newly developed NexCircle® R401:

• Melt strength is restored
• Film production becomes stable
• Breakages and interruptions are reduced
