Evaluated Alternative PFC-free food packaging tray Rottneros Packaging has developed a food packaging tray made from high quality pulp. The tray is manufactured entirely with Swedish wooden raw material, and it is both recyclable, renewable and biodegradable. In addition to the environmental benefits, the potential for adapting design, patterns and functionality of the packaging is much greater than if plastic or board was used. The packaging is made from 100% virgin fiber pulp and is therefore free from chemicals such as mineral oil or PFAS.
