Syensqo, a global leader in advanced performance materials and chemical solutions, has successfully completed a groundbreaking recycling initiative that proves multilayer food packaging containing Ixan® polyvinylidene chloride (PVDC) can be effectively recycled within standard polyethylene (PE) waste streams. This milestone marks a major advancement in sustainable packaging, demonstrating that used food packaging can be given a second life in other applications without requiring additional stabilizers.

The trials, conducted by CSI, a recognized provider of testing and certification services under the IMQ group, confirm that PVDC-based multilayer structures—previously deemed incompatible with mechanical recycling—can be seamlessly integrated into existing recycling processes.

“Recyclability is now the primary requirement for food packaging. While multilayer films offer exceptional barrier properties and play a crucial role in reducing food waste, they have historically been considered impractical for mechanical recycling,” said Federico Baruffi, Global Marketing Manager Packaging at Syensqo. “Our tests have demonstrated that film structures incorporating Ixan® PVDC are fully compatible with PE recycling. This breakthrough opens new opportunities for sustainable material management by enabling used food packaging to be repurposed without additional stabilizers.”

PVDC is widely recognized for its superior oxygen and water vapor barrier properties in food packaging, making it indispensable for preserving freshness and extending shelf life. The trials specifically examined high-barrier meat packaging structures made from PE/EVA/Ixan®/EVA/PE multilayer films. The recycling process was assessed against a reference sample of real flexible packaging waste to evaluate its impact. Conducted in compliance with EN 13430, the European standard for packaging recyclability, the trials confirmed that Ixan® PVDC multilayer structures successfully passed all critical recycling stages, including grinding, washing, drying, extrusion, pelletizing, and injection molding—even at temperatures as high as 220°C.

A key outcome of this initiative is the validation of an open-loop recycling approach, where PVDC multilayer packaging can be efficiently processed alongside PE waste. The resulting recycled material can then be repurposed for durable applications such as injection-molded items, including flower pots, pallets, and benches. This innovation aligns with the European Union's objectives to increase plastic packaging recyclability and reduce environmental impact.

By proving that PVDC-based multilayer packaging can be mechanically recycled in a commercially viable way, Syensqo has taken a significant step toward more sustainable plastic waste management. This achievement not only benefits the circular economy but also supports regulatory efforts to enhance recycling rates across Europe.

Syensqo remains committed to driving advancements in sustainable packaging solutions, ensuring that high-performance food packaging can be both effective in preserving products and environmentally responsible in its end-of-life management.
