Not all food bags can be loaded with food
Among them, polyvinyl chloride plastic is a toxic species; polyvinyl chloride resin is non-toxic, but plasticizer phthalate dibutylate or dioctyl phthalate was added in the process of making plastics, so the food produced was The packaging bag is toxic.
In addition, stabilizers have been added to some plastic bag products, and these added stabilizers are mainly lead stearate, so that the food packaging bags produced are toxic. This lead salt is easily precipitated, and it will be caused once it enters the human body. Collective lead poisoning, so use food bags when loading food, must not be used indiscriminately. In particular, food packaging bags produced under the following conditions must be clearly distinguished.
1. Precipitation of lead will occur when PVC products come into contact with solvents such as ethyl alcohol and ethyl ether. Therefore, it is not appropriate to use polyvinyl chloride plastic products to store alcohol-containing foods.
2. When PVC meets oily foods, lead will dissolve into foods, so it is not suitable for packaging oily foods.
3, when the use temperature of PVC plastic is higher than 50°C, HC will be slowly precipitated, which is harmful to human health.
4. Waste plastics recycling products, due to the complex source of raw materials inevitably with toxic ingredients, can not be used as raw materials for the production of food packaging bags.
