For the production of trays, we have a comprehensive portfolio of bio-based and biodegradable resins. If you need transparent trays and shells, we recommend the use of our partially bio-based PET or pure PLA. However, if you want to produce a biodegradable and heat-resistant tray, we recommend the use of  Bio-Flex® F 6611. It consists of more than 60%  renewable raw materials, is biodegradable and heat-resistant up to 135 °C .
