New packaging materials based on green composite sheets consisting of poly(3-hydroxybutyrate-co-3-hydro-
xyvalerate) (PHBV) and coconut fibers (CFs) were obtained by twin-screw extrusion (TSE) followed by com-
pression molding. The effect of varying the CF weight content, i.e. 1, 3, 5, and 10 wt.-%, and the screw speed
during melt processing, i.e. 75, 150, and 225 rpm, on both the aspect ratio and dispersion of the fibers was
analyzed and related to the properties of the compression-molded sheets. Finally, the CFs were impregnated with
oregano essential oil (OEO) by an innovative spray coating methodology and then incorporated into PHBV at the
optimal processing conditions. The functionalized green composite sheets presented bacteriostatic effect against
Staphylococcus aureus from fiber contents as low as 3 wt.-%. Therefore, the here-prepared CFs can be successfully
applied as natural vehicles to entrap extracts and develop green composites of high interest in active food
packaging to provide protection and shelf life extension [-]
