Beschreibung
Zusammenfassung:	The present invention relates to a polyethylene resin composition to prevent brittle failure brokenness and stress cracking which are essential defects of polyethylene. The polyethylene resin composition comprises: a substrate having polyethylene as a main ingredient; and an additive. The additive comprises a liquid nonpolar material at room temperature. The additive is included by 0.1 to 10 mass by weight with respect to 100 mass by weight of polyethylene. 폴리에틸렌이 갖는 본질적인 결점인 취성 파괴 깨짐 및 응력 균열을 방지한다. 폴리에틸렌을 주성분으로 하는 기재와, 첨가제를 포함하고, 첨가제는, 실온에서 액체의 비극성 물질을 포함하고, 첨가제의 비율은 폴리에틸렌 100질량부에 대하여 0.1 내지 10질량부인, 폴리에틸렌 수지 조성물을 사용한다.
