Title:
BIAXIALLY ORIENTED MULTI-LAYER POLYETHYLENE FILM
Document Type and Number:
Japanese Patent JP2016147430
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a biaxially oriented multi-layer polyethylene film excellent in bag falling strength, bending resistance and transparency.SOLUTION: There is provided a biaxially oriented multi-layer polyethylene film which is obtained by laminating a surface layer obtained from an ethylenic polymer having a density of 910 to 938 Kg/mand a density higher than the density of a copolymer (b) constituting a substrate layer on at least one surface of a substrate layer obtained from an ethylenic polymer composition (B) comprising an ethylene-α-olefin random copolymer (b) having a density of 895 to 920 Kg/m, where the substrate layer and the surface layer are biaxially oriented and the plane orientation degree (ΔNp) of the thicker layer is controlled to be 0.0070 to 0.020.SELECTED DRAWING: None
