Abstract This study investigates the impact of rheological behaviour on development highly filled biocomposites for rigid applications using two grades poly(butylene adipate‐co‐terephthalate) (PBAT). PBAT, a fully biodegradable polymer, has garnered significant attention as an alternative to non‐biodegradable plastics in flexible packaging applications. However, increasing filler content PBAT can enhance its stiffness, thereby expanding potential Filler incorporation is critically influenced...

This is the first-ever scientific report on melt blending of two tough home-compostable bioplastics, namely, bio-based poly(butylene succinate-co-adipate) (BioPBSA) and adipate-co-terephthalate) (PBAT). The micrographs from scanning electron microscopy showed that morphology changed a droplet-matrix to co-continuous one as PBAT concentration was increased in blends. Rheological studies revealed an increase viscosity storage modulus some blends, specifically, with 30 wt % PBAT, compared neat...
