To study the quality and initial evaluate the safety of PPSU feeding-bottle.Methods In the standard system of food contact materials in regular inspection items, from the evaporation residue, Potassium Permanganate consumption, heavy metal, content of plasticizer and material identification, such as the dimension of tests were carried out on the PPSU feeding-bottle. Results For the testing of 28 batch PPSU feeding-bottle, its evaporation residue, potassium permanganate consumption, heavy metal, content of plasticizer and other projects are within the requirements of GB 14942-1994, but there are 17.86% of the feeding-bottle that nominal for PPSU whose main component is the cheaper PES, most products violate compasses with QS number on the outer packing.Conclusion The result showed that the quality of the PPSU feeding-bottle on the market is good, but there exist the phenomenon that using PES as PPSU, and product labeling is not standardized. In the case of lack of national standards, corporate standards failed to make up the shortfall, which create obstacles to the daily supervision.
