Migration behavior of photoinitiators in polyethylene-coated paper for takeaway fast food

The migration of photoinitiators (PIs): benzophenone (BP), ethyl 4-dimethylaminobenzoate (EDAB), and 4-chlorobenzophenone (CBP), from polyethylene (PE)-coated paper to 4% (v/v) acetic acid 10% salt-simulated food solution was quantitatively analyzed using gas chromatography–mass spectrometry. behavior the three PIs studied under specific working conditions: conventional heating, microwave power, random vibration level. rate in acidic simulants ranked BP > EDAB CBP conditions. mobility increased with increasing temperature, acceleration by 10, 15%, respectively. experimental data PE-coated different temperatures powers were used establish Crank monolayer model according Fick’s second law. diffusion coefficient D an increase According condition level, a mathematical conforming Fick established, fitting process. These results showed that could affect safety paper.
