Volatile Organic Compounds in Melon Seeds Plastic Bags

Abstract

Eight volatile organic compounds (VOCs) in melon seeds printing and packaging materials have been analyzed by a headspace gas chromatography and mass spectrometry method. The results of external standard method show that PET and aluminum foil as raw materials of melon seeds plastic bags contain less VOCs, but PE contains much more VOCs. There are more VOCs in printing inks. Red ink has the most amount of VOCs (2777.27 mg/kg). The binder contains 143.574 mg/kg of VOCs. PE and printing inks may be the main sources of VOCs in the melon seeds plastic bags. Residues of benzenes in the front plastic bag materials exceed national standards. The amount of VOCs and benzenes in the back plastic bag materials all exceed national standards.
