保鲜膜和北京塑料袋都是人们生活中经常用来包裹食物的塑料制品。很多人觉得保鲜食物用哪种都无所谓,小编在这里要告诉大家,其实这两者之间还是有区别的,接下来大家一起来了解保鲜膜和北京塑料袋区别是什么。

Plastic wrap and plastic bags are plastic products that are often used to wrap food in people's lives. Many people think it doesn't matter which kind of fresh-keeping food is used. Xiaobian wants to tell you that there is a difference between the two. Next, let's learn about the difference between fresh-keeping film and plastic bag.

保鲜膜一般是使用以下三种材质制成:聚乙烯(PE)、聚氯乙烯(PVC)、聚偏二氯乙烯(PVDC)。其中,PE、PVDC塑料袋相对安全,PE主要用于水果蔬菜的包装,PVDC主要用于一些熟食、火腿的包装。

The fresh-keeping film is generally made of the following three materials: Polyethylene (PE), polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC). Among them, PE and PVDC plastic bags are relatively safe. PE is mainly used for the packaging of fruits and vegetables, and PVDC is mainly used for the packaging of some cooked food and ham.

塑料袋原材料一般是高密度聚乙烯和低密度聚乙烯,前者就是超市的购物袋,摸起来很硬,后者多用于包装食品,摸起来较软。像是红、黑、蓝等深色塑料袋大都是使用回收的废旧塑料制品重新加工而成,严禁直接装食品。

The raw materials of plastic bags are generally high-density polyethylene (HDPE) and low-density polyethylene (LDPE). The former is the shopping bag in the supermarket, which feels very hard, while the latter is mostly used for packaging food, which feels soft. Dark plastic bags such as red, black and blue are mostly reprocessed from recycled waste plastic products. It is strictly forbidden to directly load food.

保鲜膜的特殊工艺,具有良好的透气性和保鲜性能。而普通塑料袋使用时间一久就会使得食物变质,并且材质也不如保鲜袋安全。所以,保鲜袋更适合直接装食物。

The special technology of fresh-keeping film has good air permeability and fresh-keeping performance. The ordinary plastic bags will deteriorate the food if they are used for a long time, and the material is not as safe as the fresh-keeping bags. Therefore, fresh-keeping bags are more suitable for direct food.

保鲜袋怎么用:

How to use fresh-keeping bags:

1、保持果蔬新鲜:草莓、葡萄、花椰菜、黄瓜、娃娃菜这些新鲜水果和蔬菜,放入保鲜袋再放入冰箱能延长储藏 时间。西瓜、冬瓜这些分量大的新鲜水果和蔬菜切开后,一次吃不完,放一两天切面处容易腐烂,再吃时不得不切去腐烂部分,即浪费又不卫生。这个时候你就可以把它们放入保鲜袋中,既不会窜味儿,又能延长储藏时间。

1. Keep fruits and vegetables fresh: strawberries, grapes, broccoli, cucumbers, baby vegetables and other fresh fruits and vegetables can be stored in a fresh-keeping bag and then in the refrigerator to extend the storage time. Watermelon and wax gourd, which are fresh fruits and vegetables with large quantities, can't be eaten at one time. If they are kept for oneortwo days, the cut surface is easy to rot. when they are eaten again, they have to cut off the rotten part, which is wasteful and unsanitary. At this time, you can put them in the fresh-keeping bag, which will not make them smell, but also prolong the storage time.

2、蒸鸡蛋时,打散鸡蛋、碗里加过水、撇掉上面的沫子,然后在碗上套一个保鲜袋,或者是覆盖一层保鲜膜,蒸出来的鸡蛋羹没有气孔,嫩滑爽口,小编亲测有效。

2. When steaming eggs, break up the eggs, add water in the bowl, skim off the foam, and then put a fresh-keeping bag on the bowl, or cover it with a layer of fresh-keeping film. The steamed egg soup has no pores, is tender, smooth and refreshing, and is effective in small-scale test.

3、用保鲜袋把肉食和蔬果分开存放,避免食物细菌交叉感染,更加卫生合理,冰箱看起来也更整洁了。

3. Store meat, vegetables and fruits separately with fresh-keeping bags to avoid cross infection of food bacteria, which is more hygienic and reasonable, and the refrigerator looks cleaner.

在生活中,大家还是要懂得保鲜膜和塑料袋区别,对不同的食物要选择适当的保鲜用品,不然会适得其反。

In life, we still need to know the difference between fresh-keeping film and plastic bags, and choose appropriate fresh-keeping supplies for different foods, otherwise it will backfire.
