BASF: Joint press release Confoil and BASF cooperate to develop certified double-oven compostable paper trays for packaging ready meals
DualPakECO® trays are made of lightweight cardboard and coated with BASF’s ecovio® PS 1606 biopolymer
Commercially Compostable Solution Extends End-of-Life Options for Paper-Based Food Packaging and Supports Recycling of Organics
Processing, sealing, printability and strength performance on par with conventional PET food trays
Food trays can be used in microwave and conventional ovens, in refrigerators and freezers
Bayswater, Australia/Ludwigshafen, Germany, June 29, 2022: Australian food packaging manufacturer Confoil and BASF have cooperated to develop a certified compostable and double oven-safe food tray made from paper. The paper bin is coated on the inside with BASF’s ecovio® PS 1606, a partially biobased and certified compostable biopolymer specially developed for coating paper or cardboard food packaging. The trays called DualPakECO® are certified according to Australian standard AS4736-2006 and approved for food contact according to international requirements. They can be used for ready meals such as lasagna, curries and stir-fries available cold or frozen in supermarkets as well as for catering and restaurant takeaways.
Trays extend the end-of-life options of paper-based packaging by being organically recyclable: they can be commercially composted with organic waste collected in organic bins. Thus, the new packaging solution supports the organic recycling of food scraps and food-soiled packaging, increasing the diversion of food waste from landfill and incineration.
Alternative to PET more durability
This new certified compostable solution is an alternative to classic PET packaging for ready meals: The trays can be heated in conventional ovens and microwaves, can be refrigerated or frozen. They exhibit excellent barrier properties against fats, liquids and odors helping to preserve freshness and flavors. “We wanted to create a paper-based food tray that meets all the requirements of the food industries, but with the added benefit of being certified compostable,” said Alison Buxton, CEO of Confoil. “With BASF’s ecovio® PS 1606 certified compostable biopolymer, we have found the perfect component to take the next step towards sustainable solutions in our portfolio and to help our customers achieve their sustainability goals at the same time. Our joint development represents a switch to paper-based and certified compostable to support Australia’s National Plastics Plan 2025 which aims to reduce the impact of packaging on the environment Composting trials have shown that DualPakECO® trays break down into water , carbon dioxide and nutrient-rich compost in four to six weeks under commercial composting conditions.
ecovio® PS 1606 extends end-of-life options for paper applications
The carton for DualPakECO® can be easily formed and allows printability. The board is light but rigid enough for production line installations. It also provides a secure seal on a variety of film and machine substrates. The paper tray is coated with ecovio® PS 1606 using a single-layer extrusion process. Thanks to its excellent migration barrier properties, the BASF biopolymer also allows the use of recycled paper in food applications. The high content of renewable raw materials leads to a reduction in the carbon footprint of the materials, which in turn reduces greenhouse gas emissions. “Composting is the most resource-efficient process for recycling food waste,” said Rowan Williams of Market Development Biopolymers at BASF. “This packaging solution supports a circular economy as it helps to divert food waste and soiled food packaging from landfills and incineration, avoiding the associated greenhouse gas emissions. PET food trays currently available are not reusable, they are difficult and uneconomical to recycle mechanically – so in reality they mostly go to landfill or incineration.In Confoil, we have found the perfect partner to develop a solution that proves the feasibility of food packaging that combines sustainability and high technical performance.”
ecovio® PS 1606 can be used in applications with cold or hot contents as well as for bowls and plates with dry, solid, fluid or fatty contents. BASF offers ecovio® grades for extrusion coating and lamination technology. Depending on the ecovio® grade used in combination with the type of paper or cardboard, domestic and industrial compostable solutions are possible.
Market introduction at the Australian Organics Recycling Association conference
DualPakECO® trays were introduced to the market at the 2022 Australian Organics Recycling Association (AORA) Annual Conference in Glenelg, Australia. On this occasion, the president of the AORA, Peter Wadewitz, declared: “Australian standards are the strictest in the world for compostable plastics. Commercial composting is an integral part of a circular economy where organic waste can be turned into a valuable resource. rather than being thrown in a landfill or incinerated. Compost from organic recycling can be used in agriculture to improve degraded soils and return organic matter to soils ensuring future productivity. The new packaging solution is suitable for recycling organic materials such as Australia’s FOGO (Food Organics and Garden Organics). This is a curbside collection service that allows leftover food to be added to the garden bin so that it can be recycled into high-quality compost. Under the National Waste Policy Plan, Australian states and territories have pledged to increase FOGO collection services, agreeing to introduce them to all households and businesses by the end of 2023.
