  • COMPOSTABLE OXYGEN BARRIER COMPRISING A BIODEGRADABLE POLYMER MATRIX AND BIOCARBON
    Publication number: 20230192983
    Abstract: A biodegradable composite comprising a polymeric matrix including but not limited to poly lactide (PLA), poly (butylene succinate) 20 (PBS), poly(butylene succinate adipate) (PBSA), including bio-based PBSA (BioPBSA), poly(butylene adipate-co-terephthalate) (PBAT), polycaprolactone (PCL), polyhydroxyalkanoate (PHA(s)), poly(3-hydroxy)butyrate (PHB), poly(3-hydroxy-butyrate-hydroxyvalerate) (PHBV), copolyester of the monomers 1.4-butanediol, adipic acid and terephthalic acid (Ecoflex™) and polypropylene carbonate (PPC), and biocarbon, a.k.a. biochar or pyrolyzed biomass as a sustainable filler. The biodegradable composite achieves high oxygen barrier with balanced water barrier. Also, a method of manufacturing the biodegradable composite and articles of manufacturing comprising the biodegradable composite. The articles of manufacturing have application in limiting gas permeation into a package and extending shelf life of a material.
