Which material is better, pp or pa?

I believe everyone will be familiar with bottles, especially families with babies. Bottles are used almost every day until the baby doesn't have to eat milk powder. Therefore, you need to be careful when choosing a bottle. So, which material is better, pp or pa? Please come with me to see those things about bottles!

Bottle pp or pa plastic bottle: PA, also known as polyamide, is non-toxic, safe, BPA-free, transparent, tough, wear-resistant, oil-resistant, water-resistant and enzyme-resistant. PA has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubrication, and has low friction coefficient and certain flame retardancy. The melting point is above 220℃, and it can be disinfected below 200℃. PA is also widely used in medical devices, artificial blood vessels, artificial hearts and so on, which is safe and stable. It is one of the first choice materials for high-grade plastic baby bottles.

Note: Suitable for three-month-old babies.

PP bottle: PP, also known as polypropylene, is translucent, light and resistant to falling, easy to clean, safe and free of bisphenol A, and is widely used as a material for bottles and tableware. PP material is internationally recognized as a safe material for making food containers, which has strong toughness, fall resistance and impact resistance.

Note: Suitable for six-month-old babies.

PA is expensive, PC can't buy it, PP is opaque, and PPSU is the best. You can choose pa if you can. After all, the price is higher. The pp bottle is also a safety bottle and can also be used for babies. Besides choosing a good bottle, you should also choose a good nipple. There are rubber and silicone nipples, and silicone nipples are the best choice. Its hardness is similar to that of mother's nipple, and it has no odor, so it is very safe.

Which style of baby bottle is better? 1, traditional straight bottle.

This kind of bottle is economical and can be recycled. If mom likes a simple and easy-to-clean bottle, she can choose this one.

2. Recyclable bottle with curved body

The top is bent at a 45-degree angle, which can make the baby more comfortable when sucking milk. Compared with the straight bottle, the unique design can also prevent the liquid from flowing into the baby's ears and ensure the baby's health.

3. Disposable bottles

This kind of bottle consists of a hard plastic bottle and a soft plastic nipple. Squeeze the bottle before use to reduce the air in the bottle, and press the nipple when feeding the baby to prevent air from entering, but there is a disadvantage that the height of the liquid in the bottle cannot be accurately measured.

4, no bubble bottle

The bottle is spiral, and air can enter from the bottom of the bottle, which can effectively prevent the nipple from collapsing, and can also prevent the gas from entering from the nipple, so that the baby can feel abdominal distension after inhaling. In addition, the gas entering from the bottom has a great advantage that the gas will not be mixed with the liquid, so that the baby will not suck out bubbles when sucking milk.
