Zusammenfassung: | To provide a resin composition that suppresses fish eye, which is an appearance defect, and imparts an excellent mat tone.SOLUTION: A polyolefin resin composition has following components: a specific polypropylene resin (a), a specific high-density polyethylene resin (b), a specific high-density polyethylene resin (c), and a specific low-density polyethylene resin (d), with each content of these components being (a)/(b)/(c)/(d)=35-65/15-25/15-25/5-15 (weight ratio, (b)≥(c)>(d), and (a)+(b)+(c)+(d)=100).SELECTED DRAWING: Figure 1
【課題】外観欠点であるフィッシュアイの抑制と、優れたマット調付与を同時に成し得る樹脂組成物を提供する。【解決手段】特定のポリプロピレン樹脂(a)と、特定の高密度ポリエチレン樹脂(b)、特定の高密度ポリエチレン樹脂(c)と、特定の低密度ポリエチレン樹脂(d)の各成分を配合してなり、各々の配合割合が(a)/(b)/(c)/(d)=35〜65/15〜25/15〜25/5〜15(重量比;ただし、(b)≧(c)>(d)、かつ、(a)+(b)+(c)+(d)=100)であることを特徴とするポリオレフィン樹脂組成物。【選択図】図1 |
