At present, people are worried about plastic food packaging. Some people think plastic is'Poisonous'. But industry experts say plastic food bags can be used safely, but do not use colored plastic bags. When using plastic bags to pack cooked food, snacks and other direct food, it is best not to use colored plastic bags. Because the pigment used for plastic bag dyeing is more permeable and volatile, it is easy to penetrate when heated. If it is an organic dye, it also contains aromatic substances, which have certain effects on health. In addition, many colored plastic bags are made of recycled plastic, because the content of impurities in recycled plastic is high, manufacturers have to add pigments to cover up. But some plastic bags made of recycled plastic are also white. Experts also pointed out that there is no special and effective method to distinguish plastic bags, but one thing is certain. Regular manufacturers do not use plastic bags for food packaging when selling plastic bags at street stalls. In addition, plastic bags cannot be used to hold food if they have a special smell. According to reports, plastic polyethylene, polypropylene, polyester and polystyrene used for food packaging are all qualified and safe food packaging. However, consumers cannot 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 should also be used carefully. Do not use plastic bags for a long time. In daily life, people are often seen putting fried cakes, fried dough sticks, etc. in plastic bags. If you eat them in a short time, it will not cause too much harm, however, the overheating of food in the bag for a long time will cause plastic to leak on some substances and affect health. Use a microwave oven to heat food, preferably using plastic bags and special containers for microwave ovens. Freeze and freeze food in the refrigerator instead of ordinary plastic bags. In addition, buying plastic packaging also recognizes the QS logo.
