我国开发并推广无氟防油植物纤维食品包装的现状和紧迫性

植物纤维作为一种天然高分子材料，常被加工成各种纸和纸板制品用于一次性食品包装，有望替代传统塑料材料。但植物纤维防油性能不佳，目前常使用含氟有机化合物（PFAS）进行处理以提升防油性。然而，因为食品安全风险和环境保护原因，国外已有部分国家和地区制定了法规禁止在食品包装中使用PFAS，转而推广无氟（PFAS-free）防油食品包装。目前，我国无氟防油植物纤维食品包装主要有两条技术线路，能提供无氟防油解决方案的企业有十几家，但无氟产品在我国推广还存在几个方面的难点：检测标准未统一、产品性能不足、成本偏高、推广力度不够。作为大众消费品的食品包装，使用短链PFAS也存在安全风险；PFAS释放到环境中的途径多样，因而阻止PFAS释放很难；允许部分PFAS成分在食品包装材料中使用，增加了监管的难度。因此，我国应当尽快推广无氟植物纤维食品包装，利用好这次从有氟到无氟的切换过程，换道超车，孵化出拥有中国自主知识产权的食品防油技术，打造世界知名品牌。

The Current Status and Urgency of Developing and Promoting PFAS-Free, Oil-Proof Plant Fiber Food Packaging in China

Plant fiber, as a natural high-polymer material, is frequently processed into various paper and paperboard products for disposable food packaging to replace traditional plastic materials. Due to its inadequacy in oil resistance, it is often treated with fluorinated organic compounds (PFAS) to improve oil resistance. Nevertheless, because of food safety risks and environmental protection reasons, some countries and regions outside China have enacted regulations to prohibit the use of PFAS in food packaging, and instead promote PFAS-free oil-proof food packaging. Currently, the development of PFAS-free oil-proof plant fiber food packaging in China is primarily focused on two technical pathways, and there are approximately a dozen companies capable of providing such solutions. However, the widespread adoption of PFAS-free products in China faces several challenges as lack of standardized testing method, performance deficiencies, relatively high costs and insufficient promotional efforts. The use of short-chain PFAS in food packaging as mass consumption also poses potential safety risks. The diverse pathways for PFAS releasing into the environment make it challenging to mitigate their impact. Furthermore, while permitting the use of certain PFAS components in food packaging materials increases regulatory complexity. Therefore, China should promote PFAS-free plant fiber food packaging as soon as possible. This abnegation of PFAS materials in food packaging industry presents an opportunity to foster cutting-edge food oil resistance technologies with independent Chinese intellectual property rights and establish globally recognized brands in the process.
