PP material is a plastic material with good weather resistance and high temperature resistance, which can withstand high temperatures and is not easily deformed. In addition, plastic bottles made of PP material are not easily moldy and have a certain degree of corrosion resistance. Therefore, if the seasoning you purchase has a certain spicy or sour taste, you can consider choosing PP plastic bottles.
