| Abstract:This study selected 20 types of plant fiber/melamine-formaldehyde (MF) and plant fiber/polypropylene (PP) tableware to systematically analyze their material composition and the migration behavior of hazardous substances using fourier transform infrared spectrometer， X-ray fluorescence spectrometer， thermogravimetric analyzer， and migration experiments. The results showed that the primary matrices of the samples were MF and PP， with inorganic fillers such as CaCO3 and TiO2 widely added. Notably， certain products exhibited significant safety risks， MF-based samples were prone to excessive migration of melamine and formaldehyde， whereas PP-based samples primarily showed excessive overall migration limits. Correlation analysis revealed a significant relationship between inorganic filler content and migration behavior in plant fiber-plastic composite tableware. Specifically， Ca and Ti element contents were extremely significantly positively correlated with overall migration (p<0.01， r=0.951). High filler content was found to enhance interfacial defects within the material and additive migration， thereby significantly increasing safety risks. |
