Hosein Pouriman: Oxygen gas and water vapour barrier properties of blown extruded PLA/PHBV blends

Oxygen gas and water vapour barrier properties of blown extruded PLA/PHBV blends Poly(lactic acid) (PLA) and Poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV) are biodegradable polymers produced from non-petrochemical and sustainable resources with the largest global production amongst biopolymers. These two polymers' mechanical and barrier properties complement one another and can form a flexible barrier-improved monolayer blend suitable for flexible food packaging. The good biodegradable/compostable oxygen barrier films are expensive and must be part of a multi-layer structure to protect their mechanical weakness and sensitivity to moisture. On the other hand, the individual suitable barrier polymers have limited mechanical properties, e.g. sensitivity to moisture. There is a significant market demand for a monolayer flexible food packaging material with good barrier and conventional mechanical properties.This poster was uploaded for the SGS Research Showcase 2022.
