A look at your home to keep the film a lot of people put in the refrigerator before the food into the refrigerator, will be covered with a layer of plastic wrap, so that it can be better for food preservation. In fact, some of the market to sell the film did not fit with the food in the refrigerator, don’t look at this issue obscure, however the potential harm is not small. Currently on the market for the sale of plastic film from the raw materials are divided into three main categories: the first category is polyethylene (PE or LDPE); the second category is polyvinylidene chloride (PVDC); the third category is polyvinyl chloride (PVC). What are the differences between them? How can we identify the different materials of the film? Polyethylene wrap general viscosity and poor transparency, hand rub after the easy to open, and the PVC film is good transparency and viscosity, hand rub after a bad start, easy to stick in hand; polyethylene film after the fire ignited, the flame is yellow, leaving the fire is not extinguished, a drop of oil, and no pungent smell. Polyethylene (PE or LDPE) is mainly used for the packaging of ordinary fruits and vegetables; polyvinylidene chloride two (PVDC) is mainly used for the packaging of some cooked food, ham and other products; and PVC can also be used for food packaging. Here need to be reminded that, in fact, the PVC material itself as a food packaging material is safe, but because many families are now accustomed to using microwave heating food, in this case it is best not to use. Because the PVC film in the production process need to add a large amount of plasticizer, plasticizer in the heating environment is easy to release and penetrate into the food, after eating will interfere with the secretion of the body, induced disease. Consumers must be based on the actual use of the choice of cling film or fresh bag, the purchase should be carefully look at the packaging logo. Of course, if you do not understand, then, relatively speaking, to the regular supermarket to buy fresh film will be more reliable.相关的主题文章:
