Confoil and BASF DualPakECO compostable paperboard packaging

Thursday, 18 August, 2022 | Supplied by: Confoil Pty Ltd


Australian food packaging manufacturer Confoil and BASF have developed a certified compostable, dual ovenable paper tray for packaging of ready-to-eat meals.

The DualPakECO trays are made of lightweight paperboard and coated with BASF’s biopolymer ecovio PS 1606, a partly bio-based and certified compostable biopolymer developed for coating food packaging made of paper or board.  Performance regarding processing, sealing, printability and strength is claimed to be on same level as conventional PET food trays.

The trays are certified according to the Australian standard AS4736-2006 and food contact approved according to international requirements. They can be used for ready-to-eat meals like lasagne, curries and stir-fries available as cold or frozen in supermarkets as well as for catering and take-away from restaurants.

The trays are designed to extend the end-of-life options for paper-based packaging by being organically recyclable: they can be commercially composted with the organic waste collected in organic waste bins. Thus the new packaging solution supports organics recycling of food residues and food-soiled packaging, which increases the diversion of food waste from landfill and incineration.

This certified compostable solution provides an alternative to conventional PET packaging for ready-to-eat meals: the trays can be heated in conventional ovens and microwaves, can be chilled or frozen. They show good barrier properties against fats, liquids and odours, helping to preserve freshness and flavours.

Composting trials have shown that the trays break down into water, carbon dioxide and nutrient-rich compost within four to six weeks under commercial composting conditions.

The paperboard can easily be formed and allows for printability. It is lightweight yet rigid enough for in-line production facilities. It also offers secure sealing across a variety of film substrates and machinery. The paper tray is coated with ecovio PS 1606 in a mono-layer extrusion process. Due to its good migration barrier properties the BASF biopolymer also enables the use of recycled paper in food applications.

The packaging solution is suitable for organics recycling such as the Australian FOGO (Food Organics and Garden Organics).
