Cling film and plastic bags are plastic products that are often used to wrap food in people’s lives. Many people think that it doesn’t matter which kind of fresh food is used. I want to tell you here that there is still a difference between the two. Let’s take a look at what is the difference between plastic wrap and plastic bag.
Cling film is generally made of the following three materials: polyethylene (PE), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC). Among them, PE, PVDC plastic bags are relatively safe, PE is mainly used for the packaging of fruits and vegetables, PVDC is mainly used for the packaging of some cooked food and ham.
The raw materials of plastic bags are generally high-density polyethylene and low-density polyethylene. The former is the shopping bag of the supermarket, which is very hard to touch. The latter is mostly used for packaging foods and is soft to the touch. Dark plastic bags such as red, black and blue are mostly reprocessed from recycled plastic products. It is strictly forbidden to directly load food.
The special process of cling film has good breathability and freshness preservation performance. The use of ordinary plastic bags for a long time will make the food deteriorate, and the material is not as safe as the storage bag. Therefore, the storage bag is more suitable for direct food.
How to use the fresh-keeping bag:
1. Keep fresh fruits and vegetables: fresh fruits and vegetables such as strawberries, grapes, broccoli, cucumbers and baby foods. Put them in a fresh-keeping bag and put them in the refrigerator to extend the storage time. After the fresh fruits and vegetables such as watermelon and melon are cut open, they can not be eaten once. After one or two days, the cut surface is prone to decay. When they eat, they have to cut off the decayed part, which is wasteful and unsanitary. At this time, you can put them in a fresh-keeping bag, which will not bother the taste and extend the storage time.
2, when steaming eggs, beat the eggs, add water in the bowl, smash the foam above, then put a fresh-keeping bag on the bowl, or cover a layer of plastic wrap, steamed eggs without stomata, tender and refreshing, Xiaobian pro test is effective.
3. Store the meat and fruits separately with a fresh-keeping bag to avoid cross-infection of food bacteria, which is more hygienic and reasonable, and the refrigerator looks more neat.
In life, everyone still needs to understand the difference between plastic wrap and plastic bags, and choose appropriate fresh-keeping products for different foods, otherwise it will be counterproductive.
