"Smell" the smell. Qualified plastic products can only smell any smell from the nose. If you feel uncomfortable after opening the lid, it is recommended not to buy it.
"Touch" texture. The surface of a qualified plastic product should be smooth, have a certain strength and elasticity.
In addition, if there is any fall or breakage of the plastic container, it is recommended to stop using it, because if the surface of the plastic product has fine pits, it is easy to hide bacteria. Avoid repeated use of aging plastic appliances.
