Mayr-Melnhof upgrades GreenPeel fibre tray for fresh protein packaging

Mayr-Melnhof's MM Packaging Deeside has upgraded its GreenPeel fibre-based food tray with a continuous double-rim structure to improve seal integrity for skin-sealed fresh protein products such as meat, fish and chilled meals. The first application, a 20mm tray, was developed with a major French poultry producer and required changes to machinery and tooling; wider adoption across the GreenPeel range is planned.

Why this mattersReinforced fibre-tray designs that match plastic-tray seal performance widen the addressable protein-packaging market for cartonboard converters at plastics' expense.

• MM Packaging Deeside has added a double-rim structure to its GreenPeel cartonboard food tray, replacing the prior single-rim design.
• GreenPeel uses up to 90% less plastic than conventional plastic trays.
• The first application is a new 20mm tray for fresh protein, developed with a major poultry producer in France.
• MM Packaging modified its machinery and tooling to produce the new format.
• Wider rollout of the double-rim design across the GreenPeel range is planned.
• MM Packaging Ibérica's Spanish plant received an EcoVadis Platinum rating in July 2026, scoring 94 out of 100 for environmental policy.
• MM Packaging Ibérica has cut Scope 3 emissions by 53% since 2019.
• The double-rim GreenPeel tray is currently available for protein applications such as meat and fish, with wider rollout across the range still planned.
