NOVELTY - A method of reducing particle generation from a surface of a plastic or a plastic-coated paper-based material, comprises a surface coating treatment step to modify the surface of the plastic or the plastic-coated paper-based material and reduce particle generation. USE - The method is used for reducing particle generation from a surface of a plastic or a plastic-coated paper-based material used in products (all claimed) such as polypropylene baby feeding bottle, polypropylene-based electrical kettles, and cooking ware, and preventing release of molecules, and micro- and nano-particles from plastic-based products. ADVANTAGE - The method treats the surface of materials to reduce the exfoliation and leaching with cost-effective coating materials. The coating material is benign, inert and harmless to the consumer and the environment and has no effect on the food being prepared or stored, nor have any effect on their integrity or the effectiveness of their purpose. The method coats benign materials onto the surface of materials, such as plastics, and other synthetic materials, to effectively prevent the release of polymer microparticles (PMPs) from materials without compromising the advantageous properties of the material (e.g. lightweight and transparency). The coating significantly reduces PMPs release from the material surface by up to 99.9%, with no significant reduction in the properties of the material, and no evidence of breakdown or leaching of the coating materials.
