Amcor, Metsä Group, G. Mondini develop fibre-based tray system with over 80% fibre recovery rate

GLOBAL – Amcor has collaborated with Metsä Group and G. Mondini to develop AmFiber, a fully integrated fibre-based tray system combining a lightweight barrier liner and top web for protein and chilled ready-meal applications, achieving a fibre recovery rate greater than 80 percent under CEPI recyclability test method Ver. 3 (2025).

The AmFiber tray is designed using Muoto, a recyclable moulded fibre packaging solution developed by Metsä Spring based on renewable wood sourced from northern forests. 

The tray is complemented by Amcor’s range of advanced barrier liners and top-web films for different product applications. 

Designed for use with Modified Atmosphere Packaging and skin technologies, the solution can help reduce plastic use while prolonging shelf life.

Performance Without Compromise

The tray system includes convenience features such as microwaveable, ovenable, and easy-peel options. 

For protein and chilled ready-meal applications, these features matter: consumers want to heat food in the same container it came in, without transferring to another dish. 

The fibre-based format meets that expectation while offering a lower environmental footprint than traditional plastic or aluminium trays.

The solution will be featured at interpack from 7–13 May in Düsseldorf, where it will run live on G. Mondini’s Trave Streamline machine in Hall 5 / Booth F24. 

The packaging system enables trays to pass through the sealing process with reduced friction, improving production efficiency. 

G. Mondini’s digital printing capabilities also allow direct customization of fibre trays, enabling strong brand differentiation while preserving a natural appearance.

Why This Collaboration Matters

Each partner brings a distinct capability to the system: Metsä Group supplies the renewable Muoto fibre material from sustainably managed northern forests, Amcor provides barrier and sealing films that protect food while maintaining recyclability, and G. Mondini contributes the sealing and printing equipment that runs the system at commercial speed. 

The result is not a material substitution but an integrated system designed for existing production lines.

The Recyclability Standard

The CEPI recyclability test method Ver. 3 (2025) evaluates how well fibre-based packaging performs in standard paper recycling mills. 

A fibre recovery rate above 80 percent means that the majority of the tray’s material can be recovered as usable fibre, with the remainder (liner, barrier, or adhesive) removed during screening. 

This threshold meets industry standards for recyclability claims.

When Fibre Replaces Plastic

A fibre tray that seals like plastic, runs on existing equipment, and recovers 80 percent of its material in paper mills is not a compromise, it is an upgrade. 

Amcor, Metsä, and G. Mondini have delivered a system that competes on performance, not just sustainability.
