Abstract

A polyolefin resin material which is excellent in adhesion strength, tear strength, impact resistance, low-temperature heat sealability, transparency, and moldability and is suitable for use in the field of polyolefin containers/packaging materials for foods, medical materials, and electronic materials. The polyolefin resin material comprises: (A) 100 to 10 wt.% ethylene (co)polymer in which (a) the density is 0.86 to 0.97 g/cm3, (b) the MFR is 0.01 to 200 g/10 min, (c) the molecular-weight distribution is 1.5 to 4.5, (d) the components soluble in o-dichlorobenzene at 23°C have a weight-average molecular weight of 8,000 to 30,000, and (e) the (co)polymer satisfies the relationship T75-T25≤-670xd+644 (1), wherein T75-T25 is the difference between the temperature T25 at which 25% of the whole (co)polymer dissolves away and the temperature T75 at which 75% of the whole (co)polymer dissolves away and d is the density, T25 and T75 being determined from the integral elution curve obtained from an elution temperature-elution amount curve obtained by the continuously temperature-rising elution fractionation method (TREF); and (B) 0 to 90 wt.% other polyolefin resin. It contains substantially no additives.
