German discount supermarket chain Aldi Süd is now offering its customers shopping bags converted by Victor Güthoff & Partner Group (Kerpen, Germany) from the biodegradable plastic Ecovio supplied by BASF (Ludwigshafen, Germany).
Ecovio consists of BASF’s Ecoflex, a petrochemical-based polyester, with polylactic acid (PLA), which is based on cornstarch.
Although petrochemical-based, Ecoflex’s molecular structure is such that it can be digested by microbes; it is completely biodegradable according to European standard EN 13432. Ecoflex makes the bag flexible, tear-resistant, waterproof and suitable for printing, while the PLA component contributes the renewable raw material. Film processors can tailor their products so that, for example, film with a higher percentage of Ecoflex will be more flexible, whereas a higher percentage of Ecovio delivers a stiffer film. —[email protected]
