Monitoring of polymer type and plastic additives in coating film of beer cans from 16 countries

Abstract Plastic debris has gained attention as anthropogenic waste in the environment, but less concerned given to metal waste despite its high abundance in aquatic environment. Metal packaging, such as can, utilizes polymeric coating films as barrier between metals and products which leads to be p...
