First of all, look at the material. It is better to choose safe and non-toxic PP material, which is resistant to high temperature, acid, and alkali, and is safer to use.

    The second is to look at the toughness of the plastic storage box. Choose a plastic storage box with good toughness, it can be used for a longer period of time. We can press the storage box hard with our hands. If the storage box can be easily pressed down and return to its original shape immediately after letting go, it means that the plastic storage box has good toughness and is not easy to break. On the contrary, if the pressing is relatively hard, it means that the plastic is relatively brittle, not resistant to falling, and easy to break.

    Then look at the thickness of the plastic storage box. Generally, the thicker the thickness, the better the quality. This is easier to judge. A thick storage box has a certain weight in the hand, and we can judge it with the naked eye.

    Furthermore, it depends on the appearance and color of the plastic storage box. A good plastic storage box has a complete appearance and smooth edges, without burrs or scratches. The color of the plastic storage box is also uniform and shiny. If it is transparent, it must have high transparency and no impurities.
