Zusammenfassung:	The present invention relates to a biodegradable, photo-degradable biofilm comprising rice hull and rice bran, and a method of its preparation. More particularly, the present presentation relates to a biodegradable, photo-degradable biofilm comprising rice hull and rice bran, starch, titanium dioxide and biodegradable polyester, which enables to retain a suitable strength to protect crops during their growth, thus being capable of reducing the cost normally required for collecting the leftover films used for covering field during cultivation and the handling cost thereof. La présente invention porte sur un biofilm biodégradable et photodégradable comprenant de la balle de riz et du son de riz et sur un procédé pour sa préparation. Plus particulièrement, la présente invention porte sur un biofilm biodégradable et photodégradable comprenant de la balle de riz et du son de riz, de l'amidon, du dioxyde de titane et un polyester biodégradable, qui permet de conserver une résistance appropriée pour protéger des cultures pendant leur croissance, ce qui permet ainsi de réduire le coût normalement requis pour la collecte de films utilisés pour recouvrir un champ pendant la culture qui restent et leur coût de manipulation.
