Patent ID: 7544422

Claim:
A laminate comprising, as at least one layer, a polyethylene resin layer that can be extrusion lamination molded, which polyethylene resin layer is laminated on a substrate, and satisfies the following requirements (A) to (D): (A) a density is 0.890-0.980 g/cm 3 ; (B) the number of long chain branches having 6 or more carbon atoms is 0.01-3 per 1,000 carbon atoms; (C) a melt tension (mN) measured at 190° C. (MS 190 ) and MFR (melt flow rate: g/10 min, 190° C.) under a load of 2.16 kg satisfy the following formula (1): MS 190 >22×MFR −0.88 (1) and a melt tension (mN) measured at 160° C. (MS 160 ) and MFR (melt flow rate: g/10 min, 190° C.) under a load of 2.16 kg satisfy the following formula (2): MS 160 >110−110×log(MFR) (2) (D) an endothermic curve obtained in temperature-rise measurement by a differential scanning calorimeter shows one peak.
