Colorless food plastic packaging can be used with confidence

At present, people are always worried about plastic food packaging bags. Some people even think that plastics are "toxic." However, industry experts believe that plastic food packaging bags can be used with confidence, but do not use colored plastic bags for food.

Experts specifically reminded that when using plastic bags for foods such as cooked foods and snacks, it is best not to use colored plastic bags. Because pigments used for plastic bag dyeing have strong permeability and volatility, they can easily seep when exposed to oil and when exposed to heat. If it is an organic dye, it will contain aromatics, which will have a health effect. In addition, many colored plastic bags are made of recycled plastics. Because there are many impurities in recycled plastics, manufacturers have to add pigments to cover them. However, some plastic bags made from recycled plastics are also white. Experts also pointed out that there is currently no effective way to distinguish plastic food bags, but one thing is certain that plastic bags produced by informal manufacturers and sold in street stalls should never be used for food packaging. In addition, if the plastic bag has a special smell, it cannot be used to hold food.

According to reports, the plastics currently used for packaging foods such as polyethylene, polypropylene, polyester, polystyrene, etc., are hygienic in quality and are safe for food packaging. However, consumers can not distinguish between food and non-food plastic bags, so a large number of unqualified plastic bags are used for food packaging, which seriously endangers people's health.

Although plastic food packaging bags are safe, they must be used with care. Do not use high temperature foods in plastic bags for a long time. In daily life, people often see hot-fried fried cakes, fried dough sticks, etc. in plastic bags. If they are eaten in a short period of time, there is not much harm, but if the food is kept in the bag for a long time, it will make Some substances in plastic bags seep out and affect health. Microwave heating food, it is best to use microwave oven special plastic bags and special containers. Refrigerator and frozen foods in the refrigerator use plastic wrap instead of ordinary plastic bags. In addition, buy the plastic wrap and also look for the QS logo.
