1. Preface:

The issue of residual solvents in food packaging is a complex problem. In the process of producing composite flexible packaging materials for packaged food, it is usually necessary to go through processes such as printing, compounding, slitting, and bag making. In the printing process, different types of ink should be selected according to the substrate to be printed, and different mixed solvents should be used for the same elbow that uses different types of inkResidual solvents affect consumers' physical health. GB/T1005-1998 "Biaxially oriented polypropylene (BOPP)/low-density polyethylene (LDPE) composite films and bags" specifies the residual solvents and detection methods. The GC2010 series and GC2020 gas chromatographs produced by Tengzhou Zhongke Spectral Analysis Instrument Co., Ltd. meet the solvent residue testing standards.
