The present invention provides a film including, in at least a part thereof, a layer comprising an ethylene-based resin, which is a copolymer of ethylene and an &#x3b1;-olefin of 4 to 10 carbon atoms, and satisfies the following requirements (1) to (5) at the same time or an ethylene-based resin composition containing the resin;

Film or laminate comprising ethylene-based resin or ethylene-based resin composition

The present invention provides an ethylene polymer that has excellent fluidity and moldability as well as gives a molded product having excellent mechanical strength. The ethylene polymer of the present invention contains 0.02 to 1.50 mol % of a constitutional unit derived from &#x3b1;-olefin having 6 to 10 carbon atoms, and has the density of 945 to 975 kg/m, which satisfies both of the following requirements [1] and [2] simultaneously:

Ethylene polymer and use thereof

An ethylene polymer containing 0.01 to 1.20 mol % of a constitutional unit derived from &#x3b1;-olefin having 6 to 10 carbon atoms, wherein with respect to cross fractionation chromatography (CFC), either (1) the weight average molecular weight (Mw) of the components eluted at 73 to 76&#xb0; C. does not exceed 4,000, or (2) the ethylene polymer satisfies the following relationship (Eq-1), provides a molded product having excellent moldability and therefore excellent mechanical strength and appearance:&#x2266;0.1&#x2003;&#x2003;(Eq-1)wherein Sis the sum of the total peak areas related to the components eluted at 70 to 85&#xb0; C., and Sis the sum of the total peak areas related to the components eluted at 0 to 145&#xb0; C.
