In our daily life, plastic bags are often used. Especially when we buy vegetables everyday, we put them in the refrigerator directly. Is this harmful to our health? The following plastic bag manufacturers and technicians to answer for you.
There is information on the Internet that if vegetables are stored in plastic bags and stored in refrigerators, it is a kind of chronic suicide, especially in colorful plastic bags for vegetables. These plastic bags contain benzopyrene, which may be transferred to food after contacting with food and may cause cancer overnight. This idea has some truth, but it is a bit alarmist and a little more serious.
First of all, it is a fact that plastic bags contain harmful ingredients such as benzopyrene and plasticizer. But in our country, there are strict standards for the manufacture of plastic materials. Only plastic products that meet the requirements of relevant national specifications and use food packaging materials at room temperature or refrigeration temperature can ensure their safety.
Secondly, nowadays, most food bags are transparent white plastic bags, but color plastic bags are rare. Although the harmful ingredient benzopyrene is contained in the color plastic bag, the temperature in the refrigerator is low and basically constant. Under this condition, the chemical benzopyrene is comparatively stable, and will not become a food colorant, and will be transferred to the food at will.
Thirdly, for most households, vegetables or steamed bread are stored in plastic bags for a day or two in the refrigerator, which will not exceed a week at most, and plastic bags are not easy to volatilize toxic substances in such a short period of time.
But the plastic bag factory reminds a wide range of friends that if vegetables are placed in plastic bags and stored in refrigerators, they may grow pathogens because of the high humidity around the vegetables, which may easily lead to the transformation of novel vegetables. Therefore, it is not advisable to store vegetables in plastic bags for a long time.
