Evaluating Weathering of Food Packaging Polyethylene-Nano-clay Composites: Release of Nanoparticles and their Impacts
When nanomaterials added to consumer products create products with improved properties. However, it is necessary to evaluate the potential of adverse impacts on the environment and the human health. This study has shown there is strong evidence that the stability of two types of food packaging low density polyethylene (LDPE)-clay composite films are altered when exposed to environmental conditions, UV-irradiation or ozone in the presence of moisture. Both LDPE samples underwent oxidative degradation during UV irradiation or ozone exposure resulting in a substantial change in physical, structural, and thermal properties releasing clay nanoparticles.
This dataset is associated with the following publication:
