Trialling a new fibre-based ready meal packaging

With headquarters in Finland, Huhtamaki researchers, led by Harald Kuiper in the Netherlands, have been working to create a tray that will cook the food safely and can handle the temperatures and humidity of a microwave or conventional oven.

The concept is being tested with two Italian style ready meals at a major UK retail chain in May-June. The trial is part of a project aiming at developing a bio-based ready meal package for the UK market. The new tray offers a viable alternative to black plastic packaging, which is problematic for the waste processers' lasers that identify materials for recycling.

Ready meal consumption continues to grow throughout Europe and new sustainable solutions are welcome. The new material, Durapulp, is a bio-composite, a mixture of cellulose and GMO-free polylactic acid (PLA) feels like cardboard and is made of fiber derived from Forest Stewardship Council certified sources. It is laminated with a new generation biofilm made from BioPBS, using a novel lamination method to create the technical properties (low O2 barrier, heat and wet resistance) needed for a high-end ready meal tray.

"We hope this novel solution will be well received and that this project will be a tipping point for the adoption of bio-based packages in this segment. We know that alternatives based on renewable materials are needed," said Steve Davey at Huhtamaki.

"Both producers and consumers are demanding alternatives to plastic packaging. The material Durapulp is a renewable alternative and suitable for sensitive substances such as food," said Catrin Gustavsson, Senior Vice President of Innovation and New Business at Södra.

Huhtamaki has developed this new packaging concept in partnership with Södra and Saladworks in an EU-funded project called FRESH. The FRESH-project will continue until 2020.
