SpletThe mechanical and barrier properties of blown films manufactured with blends of starch and PBAT were improved when low (≤1.5 wt%) concentrations of sericin were added. These effects, together with the formation of a more homogeneous and compact microstructure of films, allows one to hypothesize that sericin may have a compatibilizing action. SpletBetter miscibility between PBS and PBAT was observed after adding PEG. Nevertheless, zeolite particles reduced elongation at break of composite films. The composite films …
SpletThe PBS, PBAT, and PBS/PBAT showed an increase in modulus as well as a decrease in tensile strength and elongation at break with increased exposure time. Furthermore, the impact strength of PBAT remains unaffected up to 30 days of exposure. However, it was clearly observed that the fracture mode of PBS/PBAT changed from ductile to brittle after … Splet01. sep. 2016 · The Science and Technology of Flexible Packaging: Multilayer Films from Resin and Process to End Use provides a comprehensive guide to the use of plastic films in flexible packaging, covering scientific principles, properties, processes, and end use considerations.
