1. The temperature should be suitable
The main component of plastic straws is generally polypropylene. This material is relatively stable at 70 to 80 degrees Celsius, but harmful substances may be generated at ultra-high temperatures. Therefore, when using the straw, the temperature should not exceed 90°C, not below -10℃, try to use within this temperature range.
2, don’t use it multiple times
Since the inside of the straw is difficult to clean, try to use it once and avoid repeated use, so as to avoid multiple use, which will cause various bacteria to grow in the tube, which is harmful to the human body.
3, try to bring your own straws
The straws given by roadside shops are generally “three-no” straws. Try not to use them. Try to bring your own regular straws, so you can use them with confidence.
4. Avoid choosing some brightly colored straws
Some low-quality straws are bright in color and will easily dissolve and fade. These pigments usually contain lead, cadmium and other heavy metals and aniline organic dyes, which can cause damage to the liver and kidneys. Therefore, try not to use this type of straw.
