<p>The present invention is directed to a polyolefin type resin laminate comprising a base layer made of a polyolefin type resin consisting mainly of a butene-1 type polymer in which the content of other alpha -olefin units is 15 mol% or below, the intrinsic viscosity [ eta ] is 1.2 to 4.0 dl/g, the ratio Mw/Mn of the weight-average molecular weight [Mw] to the number-average molecular weight [Mn] is from 2 to 10, and the haze is 50% or below, and layers provided on each of the opposite surfaces of said base layer and made of a polyolefin type resin having a melt index [MI] of 0.1 to 30g/10 min, the haze of each of the latter layers being up to that of said base layer, wherein the haze of said laminate is 3% or below, the strain recovery rate is 90% or more and the ratio of the tear strength in the M.D. (machine direction) to the tear strength in the T.D. (transverse direction) is from 0.25 to 4.</p> |
