一次性外卖打包盒是什么材料？对身体健康的影响有哪些？

　　What material is a disposable takeaway packaging box? What are the impacts on physical health?

　　一次性外卖打包盒的主要材料包括塑料、纸和铝箔。

　　The main materials for disposable takeaway packaging boxes include plastic, paper, and aluminum foil.

　　一次性外卖打包盒的材料选择多样，主要取决于其功能和用途。塑料材质的一次性外卖打包盒通常使用聚丙烯（PP）塑料，这是因为PP塑料具有良好的耐热性和较高的使用率，能够满足外卖食品的包装需求。纸质一次性外卖打包盒则通常采用食品级塑料薄膜覆盖，以确保食物的安全和卫生。铝箔材料则多用于火锅、烤鱼和烧烤等需要保持食物温度和口感的场合。

　　The material selection for disposable takeaway packaging boxes is diverse, mainly depending on their function and purpose. Disposable takeaway packaging boxes made of plastic materials usually use polypropylene (PP) plastic, because PP plastic has good heat resistance and high usage rate, which can meet the packaging needs of takeaway food. Paper disposable takeaway packaging boxes are usually covered with food grade plastic film to ensure food safety and hygiene. Aluminum foil materials are mostly used in occasions such as hot pot, grilled fish, and barbecue where food temperature and taste need to be maintained.

　　在选择一次性外卖打包盒材料时，安全性是一个重要的考虑因素。例如，聚丙烯（PP）塑料是唯一可以放进微波炉的塑料盒，因其耐热性达到130℃，且可以在清洁后重复使用。相比之下，聚苯乙烯（PS）塑料虽然耐热耐寒，但不能用于微波炉加热，且不能盛装强酸、强碱性物质。此外，一次性外卖打包盒的材质还包括聚酯（PET）、高密度聚乙烯（HDPE）、低密度聚乙烯（LDPE）、聚氯乙烯（PVC）等，每种材质都有其特定的使用条件和限制。

　　When choosing materials for disposable takeaway packaging boxes, safety is an important consideration. For example, polypropylene (PP) plastic is the only plastic box that can be placed in a microwave oven, as it has a heat resistance of up to 130 ℃ and can be reused after cleaning. In contrast, although polystyrene (PS) plastic is heat-resistant and cold resistant, it cannot be used for microwave heating and cannot contain strong acids or alkaline substances. In addition, the materials of disposable takeaway packaging boxes also include polyester (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC), etc., each of which has its specific usage conditions and restrictions.

　　一次性外卖打包盒对身体健康的影响有哪些

　　What are the impacts of disposable takeaway packaging boxes on physical health

　　一次性外卖打包盒对身体健康的影响主要包括可能致癌的风险以及其他化学物质的潜在危害。

　　The impact of disposable takeaway packaging boxes on physical health mainly includes the potential risk of cancer and the potential harm of other chemicals.

　　致癌风险：部分一次性外卖打包盒由塑料制成，如果质量较差，可能会在高温下释放出有毒物质，如双酚A、邻苯二甲酸酯等。这些物质被食物吸收后，可能会影响食物的营养价值，导致营养流失，并可能提高患癌症的几率12。

　　Cancer risk: Some disposable takeaway packaging boxes are made of plastic, and if the quality is poor, they may release toxic substances such as bisphenol A and phthalates at high temperatures. After these substances are absorbed by food, they may affect the nutritional value of the food, leading to nutrient loss and potentially increasing the risk of cancer.

　　其他化学物质的潜在危害：

　　Potential hazards of other chemical substances:

　　塑化剂：虽然外卖塑料容器使用的塑料类型（如PVC）可能含有塑化剂，但正规厂家生产的合格产品，并且在正确使用下，不会有过量的塑化剂释放到食物中。

　　Plasticizer: Although the type of plastic used in takeaway plastic containers (such as PVC) may contain plasticizers, qualified products produced by legitimate manufacturers, and when used correctly, will not release excessive plasticizers into food.

　　双酚A：一些一次性餐盒可能含有双酚A，这是一种类雌激素物质。经高温后，双酚A可能会从餐盒中渗出，进入体内。虽然食品接触材料中的双酚A可能会转移到食品上，但外卖塑料容器主要使用的材料并不需要使用双酚A3。

　　Bisphenol A: Some disposable meal boxes may contain bisphenol A, a type of estrogenic substance. After high temperature, bisphenol A may seep out of the lunch box and enter the body. Although bisphenol A in food contact materials may transfer to food, the main material used in takeaway plastic containers does not require the use of bisphenol A3.

　　二恶英：虽然有说法认为某些塑料在特定条件下可能释放二恶英，但目前并没有合理的科学证据显示这些塑料在冷藏温度下会产生二恶英。

　　Dioxins: Although there are claims that certain plastics may release dioxins under specific conditions, there is currently no reasonable scientific evidence to suggest that these plastics produce dioxins at refrigeration temperatures.
