济南塑料袋：塑料袋，不宜装烫食

来源：/ 日期：2024-09-21

　　我们的日常生活似乎离不开塑料制品：水杯、餐具、吸管、打包盒等……尤其是去菜场买菜、购物，为了方便称重，商家都会提供塑料袋，供顾客自取。

　　Our daily life seems to be inseparable from plastic products: water bottles, tableware, straws, packaging boxes, etc. Especially when we go to the market to buy groceries or supermarkets, in order to facilitate weighing, merchants will provide free plastic bags for customers to pick up.

　　不少人还会在打包之余扯几个回家，用它分装菜、肉，还会用塑料袋把食物裹起来，直接塞进冰箱~

　　Many people also take a few home after packing, use them to pack vegetables and meat, and wrap food in plastic bags before putting them directly into the refrigerator~

　　但这样的行为真的不可取——塑料是个大家族，有的怕热，有的怕油……用错了很伤身！01塑料袋，不宜装烫食

　　But such behavior is really unacceptable - plastic is a big family, some are afraid of heat, some are afraid of oil... using it incorrectly can be very harmful to the body! 01 Supermarket plastic bag, not suitable for storing hot food

　　正规里的塑料袋，大多是PE材质，在常温下装一些日常用品没有问题，若是一些生鲜食品，则未必都合适了……

　　The plastic bags in regular supermarkets are mostly made of PE material, which can hold some daily necessities at room temperature without any problem. However, if it is for some fresh food, they may not be suitable

　　1、只有食品级的PE塑料袋，才能用来装食物

　　1. Only food grade PE plastic bags can be used to store food

　　需要格外注意的是，只有专门的“食品级”PE材料保鲜袋才能用来装生鲜食物。

　　It should be noted that only specialized "food grade" PE material fresh-keeping bags can be used to store fresh food.

　　PE材质是一种很广泛的概念，为了适合不同的使用场景，会使用不同的添加成分和生产工艺。这会导致它们在残留物质、耐受温度、强度、硬度等方面有很大差距，因而不能看到PE标识就觉得可以用来储存食物。

　　PE material is a very broad concept, and different additives and production processes are used to suit different usage scenarios. This will result in significant differences in residual substances, temperature tolerance, strength, hardness, and other aspects, making it impossible to see the PE label and assume that it can be used to store food.

　　2、PE塑料袋也有缺陷

　　2. PE plastic bags also have defects

　　①耐热性不是很强，不到80℃，一旦超过可能会出现熔化、分解。

　　① The heat resistance is not very strong, below 80 ℃, and once exceeded, melting and decomposition may occur.

　　②不宜长时间接触油脂。PE的原料主要是低密度聚乙烯（LDPE）和线性低密度聚乙烯（LLDPE），在接触油脂时，两种物质可能会发生一定程度的溶胀并分解，溶于油脂中，使油脂带有哈喇味。

　　② Not suitable for prolonged exposure to grease. The main raw materials for PE are low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE). When in contact with oils and fats, these two substances may swell and decompose to a certain extent, dissolve in the oils and fats, and give them a rancid taste.

　　因此，不要用透明塑料袋装热食，也不要用来分装肉类直接冻冰箱，冻肉还是建议用食品级的、密封性好的袋子。

　　Therefore, it is best not to use transparent plastic bags for hot food in supermarkets, nor to use them for packaging meat directly in the refrigerator. It is recommended to use food grade and well sealed bags for frozen meat.

　　3、2种塑料袋劝你别装食物

　　3. Two types of plastic bags advise you not to store food

　　①不要用摸起来很软且没有QS标识的塑料袋装食物，因为这类塑料袋怕油、怕热。

　　① Do not use plastic bags that are soft to the touch and do not have QS labels to store food, as these bags are sensitive to oil and heat.

　　食物温度过高时，可能析出有害物质邻苯二甲酸酯，长期食用被污染的食物，会增加高血糖、高血脂等风险。

　　When the food temperature is too high, harmful substances such as phthalates may precipitate. Long term consumption of contaminated food can increase the risk of high blood sugar, high blood lipids, and so on.

　　②彩色塑料袋不健康。因为里面可能含有“有毒有害”的成分——苯并芘。尤其是常被用于装海鲜的黑色塑料袋，其实是可回收再生塑料。因此，不要用彩色塑料袋装直接吃的食物。

　　② Colorful plastic bags are unhealthy. Because it may contain a "toxic and harmful" ingredient - benzo [a] pyrene. Especially the black plastic bags commonly used for storing seafood are actually recyclable and recycled plastics. Therefore, do not use colored plastic bags to directly eat food.
