The work aims to identify polyethylene recycling plastics in polyethylene products by GB 9687—1988 Hygienic Standard for Polyethylene Products Used as Food Containers and Tablewares. Eight kinds of different proportions of the recycled materials were mixed into the mixture of high density polythene (HDPE) and low density (LDPE) used as main raw materials. After blow molding and forming, sensory index test, evaporate test, potassium permanganate consumption test, heavy metal (by Pb) test and decolorization test were carried out respectively. When recycling plastics additive amount increased from 0% (mass fraction) to 100%, the color of product changed from white to brown, and evaporation residue gradually reduced. In conclusion, when recycling plastics additive amount exceeds 30%, recycling plastics can be identified by color in sensory index test. It is advised to increase quantitative sensory index and fluorescent whitening agent index in GB 9687—1988 Hygienic Standard for Polyethylene Products Used as Food Containers and Tablewares.
