Mechanical properties, high tensile strength, high strength, excellent elastic and stress crack resistance, good chemical stability, strong acid resistance, strong alkali and most organic substances, excellent air tightness, water vapor barrier, melting point up to 170 degrees, Particularly suitable for high temperature sterilization is an excellent material for the manufacture of medicinal plastic bottles.

The medicinal polypropylene bottle is generally produced by the injection blowing process, so that the bottle mouth and the thread precision are high, the shape of the bottle body is stable, and the bottle cap and the bottle mouth are more suitable for the purpose, which is beneficial to the improvement of the sealing performance of the medicinal plastic bottle. Therefore, the medicinal plastic bottles produced by the injection blowing process are generally welcomed.
