Ecoflex® is BASF’s completely biodegradable plastic. Ideal for rubbish bags or disposable packaging, Ecoflex® actively reduces waste by decomposing in soil or in compost within a few weeks without leaving any residues.
Ecoflex® can be processed in many different ways, for example, as tubular film, as an extrusion coating or as cast film. Like polyethylene, Ecoflex® is water-proof, tear resistant, flexible, fusible and can be printed on. It is particularly suitable for films and for lamination to starch foam packaging.
Why does Ecoflex decompose?
Ecoflex® is made up of the building blocks adipic acid, butanediol and terephthalic acid. The principle of the arrangement of these components corresponds to a structure of the type that is also present in compounds found in nature. This is why a large number of widespread microorganisms encountered in the soil and in composting sites can break down the Ecoflex structure into its original building blocks and can utilize them to form natural metabolic products. For instance, after a mere three months in a composting facility, all that is left of this plastic is water, carbon dioxide and biomatter totally without any other residues.
