How can cling film be harmful?

Cling film, often made from polyvinyl chloride (PVC) or polyethylene, can be harmful due to the potential leaching of harmful chemicals like phthalates and dioxins when heated or in contact with fatty foods. Additionally, improper disposal contributes to environmental pollution, as plastic waste can persist in ecosystems for hundreds of years. Furthermore, the production of cling film involves fossil fuels, contributing to greenhouse gas emissions and climate change.
