The effect of polyhydroxybutyrate (PHB)-based coatings combined with a plasticizer (Tributyrin, TB), and cellulose nanocrystals (CNC) in a bilayer configuration with paperboard was investigated. PHB/paperboard composite formulations were processed by compression molding, using 15wt% of PHB with respect of paperboard. The presence of TB and CNC in the coating system favored both the interaction between layers and the enhancement of tensile properties for PHB/paperboard composites. In addition, the presence CNC in the PHB-based layer improved the water vapor permeability of bilayer composites. Disintegration in composting condition of PHB/paperboard composites was carried out according to the standard ISO 20200. The test permitted to demonstrate that all the studied samples disintegrated completely in less than 49 days of incubation.

Abstract:	The effect of polyhydroxybutyrate (PHB)-based coatings combined with a plasticizer (Tributyrin, TB), and cellulose nanocrystals (CNC) in a bilayer configuration with paperboard was investigated. PHB/paperboard composite formulations were processed by compression molding, using 15wt% of PHB with respect of paperboard. The presence of TB and CNC in the coating system favored both the interaction between layers and the enhancement of tensile properties for PHB/paperboard composites. In addition, the presence CNC in the PHB-based layer improved the water vapor permeability of bilayer composites. Disintegration in composting condition of PHB/paperboard composites was carried out according to the standard ISO 20200. The test permitted to demonstrate that all the studied samples disintegrated completely in less than 49 days of incubation.
