Precautions for using plastic packaging bags for food
zigzag experimental machine operates in ordinary life, and then hydraulic universal experimental machine usually only uses plastic bags to package food in elevation. However, people often ignore the fact that some plastics are toxic to human body, and simply pick up a plastic bag and use it to contain food
PVC plastic is a poisonous variety; PVC resin is non-toxic, but when the plasticizer dibutyl phthalate or dioctyl phthalate is added in the process of making plastics, they are toxic. In addition, some plastic products are added with stabilizers, and these stabilizers are mainly lead stearate, which is also toxic. This lead salt is very easy to precipitate, and once it enters the human body, it will cause accumulation 2 Please note that the cold and hot shock testing machine must be safely and accurately connected to the ground lead poisoning, so when loading food, you should use special food bags and never use them indiscriminately. In use, you should pay attention to the following points:
1 Lead will be separated out when PVC products are in contact with solvents such as ethyl alcohol and ether, and the shaking table, so it is very inappropriate to store alcoholic food with PVC plastic products
2. When PVC meets oily food, lead will dissolve into food, so it is not suitable for packaging oily food
3. When the temperature of PVC plastic is higher than 50 ℃, HC will slowly release, which is harmful to human health
4. Recycled waste plastic products, due to the complex source of raw materials, inevitably contain toxic ingredients, and can not be used as food packaging
people use polyethylene and polypropylene plastic products without additives to pack food everyday. It is reassuring to use them as food bags
