Title
(EN) RIGID BIODEGRADABLE FOOD CONTAINER
(FR) RÉCIPIENT ALIMENTAIRE BIODÉGRADABLE RIGIDE
Abstract
(EN) The present invention relates generally to the field of biodegradable food containers. In particular, the present invention relates to rigid food containers comprising at least one layer comprising polyhydroxyalkanoate (PHA) and another layer comprising cellulosic fibres. For example, the food container may be a food bottle. One embodiment of the present invention relates to a rigid biodegradable food container comprising an inner container comprising at least one PHA biodegradable polymer and an outer container comprising cellulose.
(FR) La présente invention concerne généralement le domaine des récipients alimentaires biodégradables. Plus particulièrement, la présente invention concerne des récipients alimentaires rigides comprenant au moins une couche comprenant du polyhydroxyalcanoate (PHA) et une autre couche comprenant des fibres cellulosiques. Par exemple, le récipient alimentaire peut être une bouteille alimentaire. Un mode de réalisation de la présente invention concerne un récipient alimentaire biodégradable rigide comprenant un récipient interne comprenant au moins un polymère biodégradable de PHA et un récipient externe comprenant de la cellulose.
