食品包装用PET材料检测标准化问题及其发展对策

Abstract： Polyethylene Terephthalate （PET） materials，owing to their excellent performance and cost advantages，are widelyused in food packaging.With the strengthening offood safety supervision，the standardization of PET material detection has become increasingly important.This paper reviews the main aspects of detection for PET materials used in food packaging，analyzes major issues such as fragmentation of the standard system，lack of unified microbial detection specifications，and the mismatch between technological development and standard updates. Corresponding strategies are proposed from the perspectives of improving the standard system，standardizing detection technologies，and promoting coordination between technologyand standards.Establishing a scientific and unified standardization system for PET material detection can enhance detection eficiencyand accuracy，provide technical support for food packaging safety，and promote the green and high-quality development of the food packaging industry.
