Abstract

Biodegradable alternatives are required in order to minimize the environmental impacts caused by inadequate disposal of plastics, especially fast-discharge plastics such as those used in the packaging. This work studied the permeability, mechanical properties and biodegradability of PBAT/organoclay composite films. The materials were melt-mixed in an internal laboratory mixer, and films containing 1, 3 and 5% of organoclay were prepared in a chill roll extruder. The samples were subjected to UV radiation, and their properties were evaluated before and after accelerated aging. Results show that tensile properties, gas permeability and biodegradation depend on filler content and that oxygen and carbon dioxide permeabilities were affected by UV aging. Although the mechanical properties are negatively affected by filler incorporation, oxygen and carbon dioxide permeabilities decreased and biodegradability increased in the composites, making them an interesting option for use in packaging.
