Résumé
Nowadays, there is a growing interest in polymers coming from renewable sources and with biodegradable characteristics as a sustainable promising alternative to traditional petroleum-based plastics, particularly in single-use applications such as food packaging and agricultural mulch films. Among other biopolymers, cellulose is the most extended polymer in nature since it is in all plants around the world. However, the extraction of cellulose from plants requires a hydrolysis process that is questioned from an environmental point of view. On the other side, bacterial cellulose can be easily produced, for instance, from kombucha beverage as a byproduct. The obtained bacterial cellulose can be then processed into films by means of the use of a plasticizer. In this regard, this article describes how modified/functionalized vegetable oils allow to improve the film forming properties of bacterial cellulose to be used as sustainable flexible films
