Beschreibung
Zusammenfassung:	The present invention concerns, in particular, a composition for producing highly biodegradable containers and, more particularly, highly biodegradable bottles. More particularly, the composition according to the invention can be used to produce bottles capable of containing the carbon dioxide gas present in carbonated beverages. Therefore, the present invention concerns, in particular, a composition that is remarkable in that it comprises from 70% to 95% by weight of polylactic acid (PLA), 3% to 8% by weight of naturally occurring plasticisers, 2% to 7% by weight of lamellar nanofillers, 1% to 5% by weight of a second biopolymer, 0.4% to 1% by weight of antioxidants, 0.2% to 0.6% by weight of nucleating agent, 1% to 4% by weight of demoulding agent and 1% to 1.5% by weight of an organic-inorganic hybrid compound in the form of a coating.
