How to choose high-quality plastic water bottles？

The first step in choosing a water bottle is to look at the material of the water bottle, mainly the bottle body. For details, please refer to the label on the bottle or the label on the bottom.

Here I only explain to you the common water bottle materials on the market, generally marked ⑤ or ⑦.

The bottle labeled ⑤ can be used with confidence. It is a non-toxic PP material, but it should be noted that this material is easy to rupture and cannot withstand too violent collisions.

The water bottle marked ⑦ needs to be distinguished separately. This kind of water bottle needs to identify whether it contains BPA, which is an environmental estrogen.

The United States, European Union and other countries stipulate that the products of children under 3 years old cannot contain BPA.

For specific regulations, please refer to the relevant regulations of each country.

The water bottle marked ⑦ must see whether it has the mark of BPA free (BPA free). Generally, merchants will mark it as a selling point, which can be found on the bottle body or bottom.

A small amount of double BPA has little effect on the body of normal adults, so don't be overly alarmed, but children, pregnant women and the elderly must not use products containing BPA.

For example, PC is a material containing BPA.

Please do not use ordinary mineral water bottles to hold drinks. Identified as ①.

This kind of water bottle itself is non-toxic, but because illegal businesses may add plasticizer DEHP, heavy metal antimony and other toxic substances during the manufacturing process, the toxic substances will be released at high temperatures. Therefore, the bottle marked ① should not be used repeatedly or contain acidic substances for a long time.
