Analysis of Migration Behavior of Phthalates and Microplastics in Food Packaging Materials
PET plastic boxes,PE plastic bags,PP lunch boxes and PVC cling film were selected as the research objects to analyze the content,composition and migration behavior of phthalates and microplastics in food packaging materials.The results showed that phthalate was detected in all samples,the total content ranged from 0.57 μg·g-1 to 35.6 μg·g-1,and the content of phthalate was the highest in PVC cling film.The microplastic analysis found that the number of microplastic particles in PVC cling film was more than that in PP lunch boxes,and the particle size was larger.This study provides a scientific basis for evaluating the safety of food packaging materials,and can provide a basis for improving the manufacturing process of packaging materials and formulating relevant standards.
