<p>PROBLEM TO BE SOLVED: To provide a laminate film excellent in flexibility and showing moderate adhesiveness as well as small in adhesion enhancing, capable of controlling a bleeding component and excellent in stain resistance.SOLUTION: There is provided a laminate film having at least two layers of a substrate layer (X)/an adhesive layer (Y) and the adhesive layer (Y) consists of 100 to 20 wt.% of a propylene-ethylene block copolymer (A) satisfying following (a1) to (a3) and 0 to 80 wt.% of a styrenic elastomer. (A) polypropylene-ethylene block copolymer (a1) a propylene-ethylene block copolymer obtained by adjusting a propylene single polymer or a propylene-ethylene random copolymer (A1) having the ethylene content of 7 wt.% or less at 30 to 95 wt.% by using a metallocene catalyst and the propylene-ethylene random copolymer containing more ethylene than the component (A1) (A2) by using the metallocene catalyst at 70 to 5 wt.%. (a2) A tanδcurve has a single peak at 0°C or lower in a temperature-loss tangent (tanδ) curve obtained by a solid viscoelasticity measurement (DMA). (a3) A component amount W of a weight average molecular weight of 5,000 ort less obtained by a gel permeation chromatography (GPC) measurement (Mw≤5,000) is 0.8 wt.% or less of the total.</p> |
