According to national regulations, the use of plastic materials of different materials is very different. The most contacted in our daily life is the plastic products from 01 to 07.
No. 01 polyester, used in the manufacture of mineral water bottles and carbonated beverage bottles, the use of taboos as described above.
No. 02 high-density polyethylene, used in the manufacture of cleaning supplies bottles and bath products bottles, it is best not to recycle. Because such containers are not easy to clean, residual cleaning products can become a hotbed of bacteria.
No. 03 polyvinyl chloride, used to make cable sheaths and some decorative materials, but some irregular plastic bag manufacturers will use them to make plastic bags to reduce costs, and the harm will not be described.
No. 04 low-density polyethylene, used for making plastic wrap, is not strong in heat resistance. When the temperature exceeds 110 degrees Celsius, hot melt phenomenon occurs and harmful substances are generated. It is recommended not to put food covered with plastic wrap in a microwave oven.
No. 05 polypropylene, used to make microwave lunch boxes, high temperature resistance. However, some microwave oven lunch boxes are made of polypropylene and the lid is made of polyester. Since polyester is not resistant to high temperatures, it is recommended that the public remove the lid before placing it in the microwave oven.
Polystyrene No. 06, used to make bowls of instant noodles and snack boxes, can not be placed in a microwave oven to avoid excessive temperature and release chemicals; do not contain strong alkali, strong acid (such as orange juice), so as not to be decomposed Polystyrene is harmful to human health.
Other plastic codes No. 07 are mainly made into cups and bottles. One of them is called PC glue, which is often used to make bottles. However, in the past, when the material was heated, it released the toxic substance bisphenol A, which affected the health of the baby. Although this problem has been solved in recent years, it is recommended that the bottle should be replaced every three months or so, and the maximum time of use should not exceed six months.
