摘 要
食品包装材料作为保障食品安全性和提升食品品质的重要环节，其选择与应用对现代食品工业具有深远影响。本研究以当前食品包装材料的广泛应用为背景，深入探讨不同类型包装材料对食品安全性及品质的影响机制。研究旨在明确包装材料在阻隔性能、化学迁移、微生物防护等方面的特性，并评估其对食品保质期、营养成分保留及感官质量的作用。通过实验室模拟实验与实际案例分析相结合的方法，选取典型塑料、金属、玻璃及新型可降解材料进行系统测试，重点考察其在不同储存条件下的表现。结果表明，不同包装材料对食品的安全性与品质存在显著差异，其中新型可降解材料在兼顾环保性能的同时展现出良好的阻隔性和较低的化学迁移风险，而传统材料如塑料则需关注潜在有害物质的迁移问题。此外，研究发现包装材料的选择应综合考虑食品类型、储存条件及消费者需求等因素。本研究的创新点在于首次将环境友好型包装材料纳入安全性与品质评价体系，并提出基于全生命周期的包装材料优化策略，为食品工业提供了科学依据和实践指导。研究成果不仅有助于推动绿色包装技术的发展，还为提升食品供应链的整体安全性和可持续性作出了重要贡献。

Abstract
Food packaging materials play a critical role in ensuring food safety and enhancing food quality, and their selection and application have profound implications for the modern food industry. Against the backdrop of the widespread use of current food packaging materials, this study delves into the mechanisms by which different types of packaging materials influence food safety and quality. The aim is to clarify the characteristics of packaging materials in terms of barrier properties, chemical migration, and microbial protection, as well as to evaluate their effects on shelf life, nutrient retention, and sensory quality of food. By combining laboratory simulation experiments with real-world case analyses, typical materials such as plastics, me tals, glass, and novel biodegradable materials were systematically tested, with a focus on their performance under various storage conditions. The results indicate that different packaging materials significantly affect food safety and quality. Notably, novel biodegradable materials demonstrate excellent barrier properties and low chemical migration risks while maintaining environmental friendliness, whereas traditional materials like plastics require attention to the potential migration of harmful substances. Furthermore, the study reveals that the selection of packaging materials should take into account factors such as food type, storage conditions, and consumer demands. An innovative aspect of this research is the inclusion of environmentally friendly packaging materials within the fr amework of safety and quality assessment, along with the proposal of optimization strategies based on a full lifecycle analysis. This provides scientific evidence and practical guidance for the food industry. The findings not only contribute to the advancement of green packaging technology but also significantly enhance the overall safety and sustainability of the food supply chain.
