How to use plastic bags to contain food

at present, people always have one or another concerns about plastic food packaging bags, and some even think that plastic is toxic. However, industry experts believe that plastic food packaging bags can be used safely, but do not use colored plastic bags for food

it is reported that the sanitary properties of plastic polyethylene, polypropylene, polyester, polystyrene, etc. currently used for food packaging are qualified to produce high-quality wax products, and it is safe to use for food packaging. However, consumers cannot distinguish between food and non food plastic bags, so a considerable number of unqualified plastic bags are used for food packaging, which seriously endangers people's health

relevant experts specially remind that when using plastic bags to package cooked food, snacks and other direct food, it is best not to use colored plastic bags. Because the pigment used for dyeing plastic bags has strong permeability and volatility, it is easy to exude when it meets oil and heat. If it is an organic dye, it will also contain aromatic hydrocarbons, which will have a certain impact on health. In addition, many colored plastic bags are made of recycled plastics. Due to the large amount of impurities in recycled plastics, manufacturers have to add pigments to cover up if the problem cannot be solved. But some plastic bags made of recycled plastic are also white. Experts also pointed out that there is no particularly effective way to distinguish plastic food bags, but one thing is certain that plastic bags produced by informal manufacturers and sold at street stalls should not be used for food packaging. In addition, plastic bags cannot be used to hold food if they have a special smell. [food China]

although plastic food packaging bags are safe, in fact, the load can not be increased, and attention should also be paid to methods in use. Don't pack high-temperature food in plastic bags for a long time. In daily life, it is often seen that some people use plastic bags to pack steaming fried cakes, fried dough sticks, etc. if they are eaten in a short time, there is no great harm, but covering overheated food in the bag for a long time will make some substances in the plastic seep out and affect health. When heating food in a microwave oven, it is best to use special plastic bags and containers for the microwave oven. Fresh keeping film should be used for refrigerated and frozen food in the refrigerator instead of ordinary plastic bags. In addition, you should also recognize the QS mark when buying fresh-keeping film. A brand of fresh-keeping film that passed the QS certification (quality safety) not long ago, when holding the publicity and education activities of buying fresh-keeping film and recognizing the QS mark, reminded that it was necessary to recognize the fresh-keeping film with the QS mark before it could be purchased with confidence. The special process and raw materials of fresh-keeping film have good air permeability and fresh-keeping performance, while ordinary plastic bags will deteriorate and rot the food if they are used for a long time, which will not achieve the purpose of fresh-keeping
