Beschreibung
Zusammenfassung:	Applicable material to obtain biodegradable films for bags by extrusion and blowing, and method of preparation thereof that focuses on the formulation and processing of bioplastics from reactive starches, reactive polyalcohols and reactive cellulose derivatives that, by co-extrusion-blowing with biodegradable polyesters, can lead to films for biodegradable bags. For this, they are mixed, in different stages: a) starch functionalized with isocyanate groups in terminal hydroxyls and polyalcoholic chains equally functionalized; b) mixture of polyester and terminally functionalized cellulose derivative; and, finally, c) extruding and blowing the previously obtained mixtures.
