In our daily life, convenience bags are closely related to our life. Whether we go shopping in the supermarket or save items, we usually use convenience bags because their functions have already covered all aspects of life. However, it should be noted that people should not use the convenience bag blindly, and some problems should be paid attention to when using it. Now, let's introduce the precautions for using convenience bags.
When heating food in microwave oven, the packaging container with "special for microwave oven" shall be selected. Fresh keeping film should be used for refrigerated and frozen food in the refrigerator instead of ordinary convenience bags. The special process and raw materials of the fresh-keeping film have good air permeability and fresh-keeping performance. However, the ordinary Kunming convenience bag will deteriorate and rot the food if it is used for a long time, which can not achieve the purpose of fresh-keeping.
When using convenience bags for cooked food, snacks and other direct food, do not use colored convenience bags. Because many of these convenience bags are reprocessed from recycled waste plastic products. At least they are added with color, so they can't directly contain food.
Try not to use convenience bags for cooked food. Cooked food packed in convenience bags often causes food deterioration. After eating, it is prone to vomiting, diarrhea and other food poisoning symptoms. It is not convenient to pack alcoholic food in bags. Alcoholic food and oily food will dissolve the lead in PVC convenience bag into food, and this kind of convenience bag can not contain food with temperature above 50 ℃.
In addition, Jinan convenience bag manufacturers remind everyone that ordinary convenience bags cannot contain food and be heated in microwave ovens. Heating convenience bags is easy to produce carcinogens, which is very harmful to human health. Consumers should use special microwave ovens to heat plastic films.
