谈到备受关注的微塑料，杜悦坦言，从塑料出现的那一天起，微塑料就有了。这就像纸和纸屑的关 系一样。只是随着技术进步，现在人们能够发现并检测到微塑料。 "微塑料主要产生在塑料产品长期使用和老化过程中。塑料餐盒作为一次性餐饮具，使用时间短、 更换频率高，很少会出现明显老化，因此消费者在使用时受微塑料影响相对有限。"杜悦补充道。 早餐店里，塑料杯装着滚烫的热豆浆；外卖订单中，冒着热气的粥被盛放在塑料盒里……近日，不 少短视频平台热传类似视频。相关视频称这些盛装热食的塑料餐盒会分泌邻苯二甲酸酯和氟化物等有毒 物质，微塑料也会渗透到食物中。部分网友调侃："手里的外卖突然就不香了"。 那么，这些盛着热腾腾食物的包装盒，是否真的存在安全风险？科技日报记者日前就此采访了相关 专家。 "我国通过《中华人民共和国食品安全法》及相关国家强制标准，对塑料餐饮具的使用进行严格管 控。具体来说，管控覆盖产品感官、总体洁净度以及芳香族伯胺迁移总量等。"中国包装科研测试中心 化学微生物检测室主任杜悦在接受记者采访时说。 目前市场上的塑料餐饮具，主要由聚丙烯制成，也有一些由聚乙烯制成。杜悦说，这两种塑料在力 学性能、延展性以及抗油防渗能力上，都 ...

Core Viewpoint - The safety risks associated with plastic food containers, particularly in the context of takeout meals, have gained public attention following a viral incident involving a man who became ill from frequent takeout consumption. The implementation of new food safety standards in China aims to address these concerns [1][2]. Group 1: Regulatory Standards - China will implement the "National Food Safety Standard for Plastic Materials and Products for Food Contact" (GB4806.7-2023) starting September 6, 2024, which mandates that plastic containers must not release harmful substances under expected usage conditions [1]. - The new standard requires that the migration of chemical substances must comply with safety limits and that products must clearly indicate the maximum usage temperature [1]. Group 2: Consumer Awareness and Safety - Experts caution that even containers labeled as "microwave safe," such as polypropylene (number 5), may still release microplastics under high-temperature conditions, despite meeting safety standards for harmful chemical migration [2]. - Consumers are advised to be vigilant about plastic material identification, timely food transfer, and cautious heating practices to mitigate health risks associated with food packaging [2]. Group 3: Market Trends and Challenges - New high-temperature resistant packaging alternatives are gradually entering the market, but their higher production costs slow down their adoption [2]. - The food service industry faces the challenge of balancing environmental sustainability and health safety with cost pressures, which requires collaboration between the industry and consumers [2].
