| Cardia Compostable B-F is a biodegradable and compostable resin based on a blend of thermoplastic starch (TPS), aliphatic polyesters and natural plasticizers. This grade of resin is compatibilised to offer a high level of mechanical strength, outstanding elongation properties and toughness. The resin is based on corn starch which is a renewable material. Cardia Compostable B-F resin is certified biodegradable during composting in professionally managed composting facilities. Complies with International Standard ISO16929, ISO 14855 Certified compostable for blown film applications up to 120 microns. Cardia Compostable B-F complies with: European Standard EN13432, USA Standard ASTM 6400, Australian Standard AS 4736 and Japanese “GreenPla” Standard Chinese Environmental Labelling. Cardia Compostable B-F is a completely biodegradable polymer suitable for the manufacturing of film-type products. It can be directly used in the film blowing process. It does not contain any non-degradable polymers such as PE, PP, PS and PVC. Independent university testing shows that after biodegradation Cardia Compostable B-F does not leave any harmful residues. This film grade has been evaluated for compostability in accordance with international standard ISO 16929 (2002-11- 01) “Plastics — Determination of the Degree of Disintegration of Plastic Materials under Defined Composting Conditions in a Pilot Scale Test”. According to the European certification scheme for biodegradable materials, Performance Standard EN 13432, the pass threshold for this test is 90% of the material passing through a 2 mm sieve after the 12 week test period. The testing shows that the plastic film samples used in this test are completely compostable as demonstrated by their 100% disintegration after 3 months and > 90% mineralization in less than 6 months. In the laboratory scale composting test according to ISO 14855: 1999 Cardia Compostable B-F film grade resin reached 90% biodegradation relative to cellulose reference material and meets the biodegradability requirement specified in the EN 13432 standard.
