Plastic baby bottle

A bottle is essential for feeding a baby. Because the baby's resistance is relatively low, when feeding the baby, you must choose a safe and harmless bottle. Plastic baby bottles are a type of baby bottle that parents prefer to use. There are many kinds of plastic materials. Generally speaking, plastic bottles made of different materials have different characteristics and their own advantages and disadvantages. The following is a detailed introduction to the relevant knowledge of baby plastic bottles.

1. PC baby bottle

PC is polycarbonate, which is a material that is used in large quantities, especially in the manufacture of baby bottles, space cups, etc. It is controversial because it contains bisphenol A. The higher the temperature, the more bisphenol A remaining in PC will be released and the faster it will be released. Therefore, PC water bottles should not be used to hold hot water.

In view of the potential hazards of bisphenol A in PC baby bottles, my country has banned the production of PC baby bottles and other infant food containers containing bisphenol A since June 1, 2011, and banned the sale of baby bottles containing bisphenol A since September 1, 2011.

2. PP baby bottle

PP, also known as polypropylene, is lightweight, drop-resistant, easy to clean, safe and does not contain bisphenol A. It is widely used in materials for baby bottles and tableware. Advantages of PP baby bottles: do not contain bisphenol A, are not easy to break, are resistant to high temperatures and have good stability.

Disadvantages of PP baby bottles: poor hardness, not wear-resistant, once the baby bottle is broken, it needs to be replaced in time.

3. PES bottle

PES is polyethersulfone resin, a transparent amber amorphous resin with excellent heat resistance, good dimensional stability, and good chemical resistance. PES has excellent reliability against rapid temperature changes and excellent processability, which makes PES widely used.

Advantages of PES baby bottles: high heat resistance, can withstand heat up to 180°C, does not produce bisphenol A when heated, and the bottle is light.

Disadvantages of PES baby bottles: The remaining milk stains are not easy to clean and they should be replaced about every six to eight months.

4. PPSU baby bottle

PPSU is polyphenylene sulfone, an amorphous thermoplastic with high transparency and high hydrolytic stability. The product can be subjected to repeated steam sterilization.

Advantages of PSU baby bottles: The bottles are lighter, less likely to break and drop, less likely to produce chemical toxins when heated or sterilized by steam, do not contain endocrine disrupting carcinogenic chemicals (environmental hormone bisphenol A), are heat resistant to 180°C, and can be heated in a microwave.

Disadvantages of PPSU baby bottles: easy to leave milk stains, difficult to clean, and easy to scratch.
