The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: Provided are: a laminate which has excellent laminate strength, has a heat seal portion with an excellent appearance, and is unlikely to cause contamination on a guide roll; and a biaxially oriented polypropylene film capable of forming such a laminate. The biaxially oriented polypropylene film comprises: a substrate layer A composed of a polypropylene-based resin composition; a surface layer B composed of a polypropylene-based resin composition; and a surface layer C composed of a polypropylene-based resin composition, and satisfies the following (1) to (4). (1) The heat shrinkage rate of the biaxially oriented polypropylene film at 150°C in the longitudinal direction is 0.0-10.0%. (2) The heat shrinkage rate of the biaxially oriented polypropylene film at 150°C in the width direction is 0.0-15.0%. (3) The anti- blocking agent falling rate in the surface layer B and the anti-blocking agent falling rate in the surface layer C are each 10% or less. (4) The laminate strength is at least 1.5 N/15 mm.
