The use of natural organic fillers in addition to postconsumerrecycled polymers is getting a growing interestduring the last years; this is due to many advantagesthey can provide in terms of cost, aesthetic properties,environmental impact. In this work, several types ofwood flour (differing each other with regard to productionsource and particle size) were added to a recycledpolyethylene coming from films for greenhouses and theeffects of filler type, content, and size were investigated.Investigation was then focused on the improvement ofmechanical properties, through the addition of polar copolymers(ethylene-co-acrylic acid, ethylene-vinyl acetate)and a maleic anhydride-grafted-grafted polyethylene(Licocene® PE MA 4351 TP), in order to try toovercome the poor adhesion between polar filler particlesand nonpolar polymer chains. Investigation wasalso based on SEM micrographs. An overall positiveinfluence of these additives was observed.
