Research on key measurement items and standard compliance of food packaging materials
食品包装材料计量检测关键项目及其标准符合性研究

摘要

食品包装材料对保障食品安全与品质至关重要，其可能存在的物质迁移与污染风险要求对关键计量检测项目进行严格监控。本研究系统分析了塑料、纸制品等食品接触材料安全检测中涉及的关键计量参数，如蒸发残渣、总迁移量及特定迁移量的测定。通过探讨这些检测中所用计量器具的选型与校准要求，评估了其与国内外标准（如中国GB 4806系列、欧盟核心法规（EU）No 10/2011及其修正案（EU）2025/351）的符合性。研究发现，检测方法不一致与器具不精确是影响标准符合性的主要因素。本文提出了计量过程的优化策略，为提高食品包装安全检测的准确性与可靠性提供参考。

Abstract

Food packaging materials play a critical role in ensuring food safety and quality. However, their potential risks of material migration and contamination necessitate strict monitoring of key measurement items. This study systematically analyzes the key measurement parameters involved in the safety testing of food contact materials, such as plastic and paper packaging, including residue on evaporation, overall migration, and measurement of specific migration amounts. By examining the selection and calibration requirements of measuring instruments used in these tests, the research evaluates their compliance with domestic and international standards, notably the Chinese GB 4806 series and the European Union's core framework Regulation (EU) No 10/2011 on plastic food contact materials along with its amendments such as (EU) 2025/351. The findings reveal that inconsistencies in measurement methods and instrument inaccuracy are major factors affecting standard compliance. This paper proposes optimization strategies for measurement processes and provides references for enhancing the accuracy and reliability of food packaging safety testing.
