Meaning
Legislative acts establish binding targets for recycled content and design for recycling in plastic packaging across European markets. The packaging waste regulation PPWR mandates specific post-consumer recycled polymer percentages for different packaging types by set milestones. This regulation forces polymer suppliers to scale up their recycling infrastructures to ensure sufficient supply of compliant resins.
It affects both flexible film extruders and rigid packaging molders by transforming raw material sourcing strategies. The act shifts the responsibility of collection and sorting onto manufacturers.
Sourcing Strategy
Procuring certified post-consumer resin becomes a necessity rather than an optional marketing strategy. Compliance with the packaging waste regulation PPWR increases the competition for high-quality recycled polyolefins. Molders must secure long-term contracts with certified recyclers to avoid production disruptions caused by polymer shortages.
Design Modification
To comply with recyclability mandates, packaging designers must eliminate multi-material laminates that are difficult to recycle. Adhering to the packaging waste regulation PPWR encourages the transition to mono-material polyethylene or polypropylene structures. This shift simplifies the collection and reprocessing of plastic waste.
Molding Process
Integrating recycled resins into thin-walled packaging can introduce contaminants that cause gel formation or pinholes. Under the packaging waste regulation PPWR, molders are forced to run resins with higher variability in melt flow index. To maintain part quality, processing variables like melt temperature and injection speed must be optimized dynamically.
