摘要： A polyolefin resin composition comprises a component A consisting of polypropylene or a propylene-ethylene block copolymer whose MFR is greater than 16 (g/10 minutes); a component B consisting of an ethylene based rubber; and a component D compatible with the component B. A ratio of summation of the propylene-ethylene copolymer part in the component A, the component B, and the component D to summation of the components A, B, and D is 25 wt. % or more and 45 wt. % or less. Further, a ratio of the blend quantity of the component D to summation of the blend quantities of the components B and D is less than 0.8. In this manner, the bending elastic modulus and the tensile breaking extension are included in a desired region, while the tensile breaking extension is improved.
摘要翻译：聚烯烃树脂组合物包含由聚丙烯组成的组分A或MFR大于16（g / 10分钟）的丙烯 - 乙烯嵌段共聚物; 由乙烯基橡胶组成的组分B; 和与组分B相容的组分D.将组分A，组分B和组分D中的丙烯 - 乙烯共聚物部分的总和与组分A，B和D的总和的比例为25wt。％以上45重量％％或更少。此外，组分D的混合量与组分B和D的混合量的总和的比例小于0.8。以这种方式，弯曲弹性模量和拉伸断裂伸长率包括在期望的区域中，而拉伸断裂伸长率提高。

摘要： A parison is hung down between a pair of molding metallic molds in the opened state, expanding members are contacted with the specified portions of the parison, and after setting the temperature difference between the specified portions and other portions in accordance with a pre-set thickness ratio between both portions after forming thereof, the expanding members are moved while cooling the specified portions of expanding members so as to extend and thin the portions other than the specified portions of the parison, and the metallic molds are closed together so as to blow compressed air into the parison to effect blow-molding.
摘要翻译：在打开状态的一对成型金属模之间，将型坯悬挂在膨胀构件与型坯的特定部分接触，并且在根据预定厚度设定指定部分和其它部分之间的温度差之后在形成后两部分之间的比例，使膨胀构件移动，同时冷却膨胀构件的指定部分，以使除型坯的特定部分之外的部分延伸和变薄，并且金属模具被关闭在一起以便压缩空气进入型坯进行吹塑。
