When using plastic bags, people have more or less concerns of one kind or another, thinking that plastics are poisonous. Especially for colored plastic aluminum foil bags, many people dare not use it to hold food. In fact, people's cognition is mainly misled by the external environment. The outside world generally believes that plastics are poisonous, which makes people enter the misunderstanding.
There are several kinds of plastics used for food packaging aluminum foil bags, such as polyethylene, polystyrene, etc., and their hygienic performance is qualified.
In fact, most of the plastics used in food aluminum foil bags are safe. However, because the plastic packaging market is too large and easy to put into production, it is difficult to manage. On the other hand, some food businesses and even consumers themselves do not have the awareness to actively distinguish between food and non-food plastic bags.
As for other foods that are not directly edible, the hygienic standards for plastic packaging can be looser, and the words "for food" do not have to be marked, but special vigilance should be paid to recycled plastic bags made of recycled plastics. It is inevitable that the waste plastics recycled by enterprises will be mixed with polyvinyl chloride and other raw materials that cannot be used for food packaging. If this kind of recycled plastic bag is used to pack food, it will cause harm to the human body, and consumers should be vigilant.
