BIAXIALLY ORIENTED POLYETHYLENE FILM, LAMINATED FILM AND PACKAGING BODY

Abstract

The present invention provides a biaxially oriented polyethylene film obtained by stretching a film made of polyethylene-based resin as the main raw material that can be stably stretched in the biaxial direction, as well as a laminated film and a packaging body. A biaxially oriented polyethylene film (10) including a substrate layer (20) and a surface layer A is provided, wherein the relationship between the calculated MFR (MFRc) of the substrate layer (20) and the calculated MFR (MFRs1) of the surface layer A satisfies 0.3 < MFRc / MFRs1 < 1.9.Also provided is a biaxially oriented polyethylene film (10A) comprising at least a substrate layer, a surface layer A, and a surface layer B, wherein the relationship between the calculated MFR (MFRc) of the substrate layer (20) and the calculated MFR (MFRs1) of the surface layer A satisfies 0.3 < MFRc / MFRs1 < 1.9, and the relationship between the calculated MFR (MFRc) of the substrate layer (20) and the calculated MFR (MFRs2) of the surface layer B satisfies 0.3 < MFRc / MFRs2 < 1.9.
