The residue and release of 28 kinds of antioxidants and ultraviolet stabilizers in polyethylene products were investigated. The samples included a total of 36 kinds of kitchenware, e. g., bags, wrapping films, sauce bottles and a chopping board, and a total of 16 food-packages, e. g., bags, cases, nets and a tube. They were analyzed using the simultaneous determination method with HPLC. Most samples contained 1-3 antioxidants, mainly Irganox 1076, Irgafos 168, BHT and Irganox 1010. The residue level was about 50-1, 000μg/g. The migration test was carried out using high-residue samples. No additives were released into water, 20% ethanol or 4% acetic acid at 60°C after 30min, though some additives were released into n-heptane at 25°C after 60min.
