Abstract
A stretch blow-molding process for the preparation of polypropylene containers, which comprises: (I) forming a polypropylene material into a preform; (ii) stretching the preform into the desired article; in which the polypropylene material comprises a crystalline propylene copolymer containing 4 to 12% by weight of at least one C4-C8 α-olefin having a melting point in the range of 105 to 120℃ and including insolubles in xylene at 25℃ higher or equal to 93% by weight.
