LDPE-Nanoclay films for food packaging with improved barrier properties

This study focuses on the development of low-density polyethylene matrix nanocomposite films for food packaging industry and aims at improving oxygen barrier properties while maintaining other relevant characteristics, such as processability, easy post-processing, optical mechanical properties. nanocomposites, with 1 2.5 wt.% nanoclay (NC) also compatibilized 5 grafted maleic anhydride (PE-g-MA), were prepared used to produce blown films. The nanocomposites characterized in terms their morphology, thermal, rheological, mechanical, properties, through scanning electron microscopy (SEM), X-ray diffraction (XRD), differential calorimetry (DSC), rheological measurements, tensile tests, water vapor transmission, permeability tests spectrophotometry. results demonstrated good NC dispersion polymer decreased All did not significantly change when compared neat polyethylene. Overall, film improved added PE-g-MA and, have potential packaging.
