Today, Xiaobian wants to share with you: 'don't often use plastic bags to hold food. ' in life, people are used to using plastic bags to hold food, however, everyone ignored the fact that plastic is toxic to the human body, and picked up a plastic bag with the right size and loaded the food. The following small series will tell you in detail.
Polyvinyl chloride plastic is a toxic variety. Polyvinyl chloride resin is non-toxic, but plasticizer dibutyl phthalate or dioctyl phthalate is added in the process of making plastic, which is toxic.
In addition, stabilizers are added to some plastic products, and these added stabilizers are mainly lead stearate, which is also toxic. This lead salt is easy to precipitate, once entering the human body, it will cause storage lead poisoning, so special food bags should be used when loading food, and it must not be used indiscriminately.
In use, the following points should be paid attention to: lead will be precipitated when polyvinyl chloride products come into contact with solvents such as ethanol and ether, so it is not appropriate to store alcoholic foods with polyvinyl chloride plastic products.
When PVC meets oily food, lead will dissolve into the food, so it is not suitable for packaging oily food.
When the use temperature of PVC plastic is higher than 50℃, HC will slowly separate out, which is harmful to human health.
Waste plastic recycled products, due to the complex source of raw materials, inevitably with toxic ingredients, can not be used for food packaging.
People use polyethylene and polypropylene plastic products without additives to pack food everyday. It is reassuring to use them as food bags.
