Abstract

PURPOSE:To manufacture a hollow molded product of good surface gloss without lengthening molding cycle by using a parison of polyolefin resin as a blow molding die and also using a molding die constituted of a fluorine resin molded product for part or the whole of the molding die including the end of the upper inner surface. CONSTITUTION:A molding die constituted of a fluorine resin molded material covering part or the whole of the same including its end of the upper inner surface as a blow molding die to extrude a parison composed of polyolefin resin is used. As for polyolefin, polyethylene consisting of 30-90wt.% of high density polyethylene having 0.945g/cm<3> or more of density, and 0.01-3.0g/10min of melt index, and 70-10wt.% of a straight-chain low density or middle density polyethylene having 0.910-0.940g/cm<3> of density, 0.1-10.0g/10min of melt index and 6.0 or less of the ratio (Mw/Mn) between the weight-average mol. wt. Mw and the number-average mol. wt. Mn should be used to manufacture a polyethylene hollow molded material of particularly good surface gloss.
