物およびその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a container-molding resin composition that substantially eliminates die-weld lines that occur when producing colored commercial containers using high-density polyethylene as a main material and a blow-molding method. It relates to its manufacturing method.

Because it has certain advantages such as excellent moldability, it has been used in large quantities to mold small household containers (bottles) for use in pharmaceuticals, cosmetics, and food products, as well as large containers (bottles) for commercial use. However,
Recently, demand for medium-sized bottles with an internal volume of 2 to 1 (liter) for commercial liquid detergents has increased, and attempts have been made to blow-mold these medium-sized bottles. Polyethylene is extruded along a mandrel and a core to form a parison, and the parison is sandwiched between molds and air is blown into the mold. During this parison formation process, the molten resin extruded from the extruder is separated and recirculated into the parison. When merging for forming, one or more lines of merging, commonly called die weld lines, often appear in the vertical direction of the hollow bottle, detracting from its aesthetic appearance.
このダイウェルドライ／発生は、顔料中にチタ／ホワイ

Next, (2) this masterbatch is mixed with high density polyethylene to achieve the desired pigment concentration.
（Ｃ）成分は、（１）、（２）のいずれの段階で混合し
てもよいが、（１）の段階で混合し、マスターバッチ中
に混在せしめた方がダイウェルドラインの解消には効果
的である。この場合、（Ｃ）成分として低分子量のもの
を用いれば分散剤の役割を果し、高分子量のものを用い
れば、高密度ポリエチレンに代用することもできる。Component (C) may be mixed at either step (1) or (2), but it is better to mix it at step (1) and mix it in the masterbatch to eliminate die weld lines. Effective. In this case, if a component (C) with a low molecular weight is used, it will play the role of a dispersant, and if a component with a high molecular weight is used, it can be substituted for high-density polyethylene.
