　　· What is a plastic bottle

　　Plastic is one of the materials of milk bottles, and there are many types of plastic materials in plastic milk bottles, such as PC milk bottles, PP milk bottles, PES milk bottles, PPSU milk bottles, etc., which are collectively referred to as plastic milk bottles.

　　· The advantages and disadvantages of various plastic bottles

　　1.PP feeding bottle

　　PP is also called polypropylene.

　　Advantages: no bisphenol A component, safe and harmless, light in texture and not brittle, with strong impact resistance, high temperature resistance and good stability, it is a recognized safe material.

　　Disadvantages: poor corrosion resistance, poor hardness, easy to wear, once damaged, you need to buy a new bottle in time.

　　2.PPSU feeding bottle

　　PPSU is also called polyphenylsulfone, an amorphous thermoplastic.

　　Advantages: no carcinogenic bisphenol A component, safe, non-toxic, transparent, drop-resistant and not easy to break, new and new material with light texture with high hydrolytic stability, can withstand high temperature of 180 degrees Celsius, chemically stable It is relatively strong and can continuously withstand high temperature disinfection without deformation, and it is not easy to produce toxic substances. Milk can be warmed or sterilized in the microwave.

　　Disadvantages: It is easy to form milk scale, and it is not easy to clean and scratch.

　　3.PES bottle

　　PES is also called polyethersulfone. Can adapt to rapidly changing temperature difference, very good heat resistance and stability.

　　Advantages: no bisphenol A component, safe and harmless, light in texture, resistant to falling and not breaking, transparent color, good heat resistance, and can withstand high temperatures of up to 180 degrees Celsius.

　　Disadvantages: If the milk scale remains in the bottle, it is not easy to clean, so the bottle needs to be replaced after six to eight months.

　　4.PC feeding bottle

　　Advantages: namely polycarbonate, good transparency.

　　Disadvantages: Contains the toxic ingredient bisphenol A, which will be precipitated into the diet when heated. The higher the heat, the more toxic ingredients will be released, and the release speed will also increase with the increase of temperature, affecting the health of infants and young children. Good health, hinder the mature development of immunity, and even cause cancer. Therefore, it is not possible to use a PC material container for hot water. Since September 1, 2011, my country has banned manufacturers from using PC and other ingredients containing bisphenol A as milk bottle materials.
