PP Twist off Bottle Caps are mostly used for gas beverage bottle cap gaskets and caps. They are heat-resistant and non-deformable, have high surface strength and good chemical stability. The disadvantages are poor toughness, easy embrittlement under low temperature conditions, and poor oxidation resistance and wear resistantance. This type of bottle cap is mostly used for fruit wine and carbonated beverage bottle cap packaging.

The strength of PP Twist off Bottle Caps increases with increasing ethylene content. The Vicat softening temperature of PP is 150 °C. Due to the high degree of crystallinity, this material has excellent surface stiffness and scratch resistance. There is no environmental stress cracking problem in PP. Typically, PP is modified by the addition of glass fibers, metal additives or thermoplastic rubber. Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8 to 2.5%, and has excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance.
