(Summary description)Plastics are important organic synthetic polymer materials and are widely used. However, the "white pollution" caused by waste plastics is becoming more and more serious. If we understand the detailed classification of plastics, it will not only help us use plastic products scientifically, but also It is conducive to the classification and recycling of plastics, and effectively controls and reduces "white pollution".

Use: It can only heat up to 70 ℃ and is easy to deform. It is only suitable for warm or frozen drinks. It is easy to deform when it is filled with high temperature liquid or heated, and releases harmful substances to the human body. Scientists also found that the No. 1 plastic product is used After 10 months, the carcinogen DEHP may be released, which is toxic to the testis.

Note: It is difficult to clean thoroughly, it is recommended not to recycle
[PVC Polyvinyl Chloride] "No. 3" PVC is often used in: common raincoats, building materials, plastic films, plastic boxes, etc. It is rarely used for food packaging at present.
Use: This material has excellent plasticity and low price, so it is widely used. It can only heat up to 81 ℃, and it is easy to produce harmful substances at high temperatures. It even releases toxic substances during the manufacturing process. If it enters the human body with food, it may cause breast cancer , Birth defects and other diseases of newborns.

【 LDPE low density polyethylene】 "No. 4" LDPE is often used in: cling film, plastic film, etc.
Use: heat resistance is not strong. Generally, qualified PE cling film will melt when the temperature exceeds 110 ℃, leaving some plastic preparations that cannot be decomposed by the human body. The oil in the food is also easy to be in the cling film The harmful substances are dissolved out. Therefore, when the food is put into the microwave oven, the wrapped cling film must be removed first. Harmful substances are produced at high temperatures.

[PS Polystyrene] "No. 6" PS is often used in: bowls of instant noodle boxes, fast food boxes.
Use: It is heat-resistant and cold-resistant, but it cannot be placed in a microwave oven to avoid the release of chemicals due to high temperature. And it cannot be used to carry strong acids (such as orange juice), strong alkaline substances, because it will decompose to Polystyrene, which is not good for the human body, is easy to cause cancer.
