advantage
1. Most plastics have strong corrosion resistance and do not react with acids and alkalis.
2. Plastic manufacturing costs are low.
3. Durable, waterproof and lightweight.

5. Is a good insulator.
6. Plastics can be used to prepare fuel oil and fuel gas, which can reduce crude oil consumption.
Disadvantage
1. When recycling waste plastics, classification is very difficult and economically uneconomical.
2. Plastics are easy to burn and produce toxic gases when burned. For example, when polystyrene is burned, toluene is produced. This kind of substance causes blindness, inhalation and vomiting, etc. PVC burning also produces hydrogen chloride toxic gas. In addition to burning, it is a high temperature environment, which causes plastic to decompose toxic components, such as benzene ring. Wait.
3. Plastics are made from petroleum refined products, and petroleum resources are limited.
4. Plastics cannot be naturally decomposed.
5. The heat resistance of plastics is poor and easy to age.
Due to the inability of plastics to degrade naturally, it has now led to the tragedy of many animals. For example, monkeys, baboons, dolphins and other animals in the zoo will accidentally swallow the No. 1 plastic bottle that the tourists left behind, and finally die because of indigestion. Looking at the beautiful and pure sea, they are close, and they are full. A variety of plastic garbage that cannot be contained in the ocean, and a variety of plastics that cannot be digested have been found in the intestines of many dead seabird samples.
The most dangerous part of plastic products is phthalate, which is the main cause of the decline in sperm count in men. At present, the EU has banned the use of various phthalates in cosmetics, teething rings and children's toys. However, pregnant women are still exposed to phthalates because they are often used to soften household items such as plastic furniture, shoes, PVC flooring and shower curtain plastics.
Phthalates enter the body through foods and water packed in plastic containers, such as canned food coatings, recyclable milk and mineral water bottles. Studies have shown that foods with higher fat content in canned foods are more susceptible to contamination, such as pork, anchovies, and sardines. Fetuses and babies, as well as adolescent children, are most sensitive to it and health is the most vulnerable.
In order to reduce the harm of phthalate to the human body, it is usually noted that it is best not to use a foam container to soak instant noodles. Do not use a plastic container containing polyvinyl chloride to heat the inlet food in a microwave oven. The right thing to do is to put the food in a heat-resistant glassware or ceramic dish for heating.
