Abstract: A polypropylene preform for biaxial stretch blow molding using a liquid as a pressurizing medium. The polypropylene material, when measured with a differential scanning calorimeter (DSC), has a relationship between the melting start temperature (Ts), melting peak temperature (Tm), and melting enthalpy (ΔHm) exhibited as (Tm-Ts)ΔHm.
