Abstract: PURPOSE:To obtain favorable fabrication properties and frosted appearance by a method wherein a container consists of a resin composition containing a polypropylene resin as a main material and a resin as a submaterial having a softening temperature higher than that of the main material in a specific compounding ratio, and the surface of the container is so structured as to have irregularities of the submaterial. CONSTITUTION:A container consists of a resin composition containing a polypropylene resin as a main material and at least one kind of resin as a submaterial having a softening temperature at least 20 deg.C higher than that of the main material in a main material/submaterial compounding ratio (weight ratio) of 98/2-60/40. The surface of the container is so structured as to have irregularities of the submaterial. A preform for the container is obtained by injecting the resin composition at a temperature higher than the melting temperatures of both the polymers at a speed of 350 mm/sec or lower, at which the dispersed resin as the submaterial cannot remarkably deform to a flat form. The preform is blown to be biaxially oriented at a temperature not higher than the softening temperature of the submaterial. As a result, the frosted appearance is obtained.

Abstract: PURPOSE:To obtain a hollow container, the whole cylindrical part of which has fine and matte appearance, by a method wherein the container concerned is made out of composition, which is prepared by mixing main material made of thermoplastic polyester resin and sub- material having the softening temperature higher than the softening temperature of the main material with each other by the predetermined mixing ratio. CONSTITUTION:Material, in which 70mol.% or more of repeating unit is made of ethylene terephthalate and the intrinsic viscosity of which is 0.65-1.5, is preferably employed as main material. At least one of materials, the softening temperatures of which are higher than the softening temperature of the main material by 20 deg.C or more, is employed as sub-material. The mixing ratio by weight of the main material/sub-material is set to be 98/2-60/40. By injection molding, preform is produced out of the composition consisting of the main material and the sub-material. At the time, the molding is performed at the linear speed of 350mm/sec under the temperature, at which both the main material and the sub-material are melted, so as not to remarkably flatten the dispersed sub-material. The obtained preform is biaxially stretching blow molded under the temperature, which is below the softening temperature of the sub-material. If the blow molding is performed at the temperature higher than the softening temperature of the sub-material, no unevenness due to the sub-material develops, resulting in obtaining no matte appearance.
