The levels of migration of 1-hexene and 1-octene residues in PE (polyethylene) products were analyzed by Headspace gaschromatography (HSGC). A total of 21 samples were including lap, polyglove, zipper bag and ect. The samples were eluted with distilled water, 4% acetic acid, 20% ethanol and n-heptan. The limit of detection (LOD) was 0.06 mg/L ~ 0.30 mg/L and limit of quantitation (LOQ) was 0.21 mg/L ~ 1.01 mg/L, respectively. But because of the high volatile, n-heptan elution was not detected 1-hexene and 1-octene standard. 1-hexene and 1-octene were not detected in the sample which eluted with simulant at $60^{circ}C$, 30min. Microwave for 1 minute also treated sample and direct heated at $100^{circ}C$ without simulant were not detected.
