Biaxially-oriented polypropylene film

A biaxially-oriented polypropylene film, comprising

• a base layer (A) comprising a first polypropylene resin as a main component,
• a surface layer (B) comprising a second polypropylene resin and provided at one side of the base layer (A), and
• a surface layer (C) comprising a third polypropylene resin and provided at one side of the base layer (A) opposite to the surface layer (B),
• wherein the surface layer (B) satisfies the following (1) to (5):
• (1) the surface layer (B) has a wetting tension of 38 mN or more;
• (2) the surface layer (B) has a surface resistance value of 14.0 Log Ω or more;
• (3) the surface layer (B) has an arithmetic average roughness (Ra) of 3.0 nm or more and 5.5 nm or less;
• (4) the surface layer (B) has a Martens hardness of 248 N/mm2 or less;
• and
• (5) the surface layer (B) has a center plane average surface roughness (SRa) of 0.010 or more and 0.026 μm or less,
• wherein the surface layer (C) satisfies the following (6) and (7):
• (6) the surface layer (C) has a center plane average surface roughness (SRa) of 0.020 μm or more and
• (7) the surface layer (C) has a Martens hardness of 270 N/mm2 or more,
• wherein the second polypropylene resin comprises (i) a mixture of two or more different polypropylene resins having different melt flow rates and (ii) one or more anti-blocking agents, and
• wherein the third polypropylene resin comprises (i) a polypropylene homopolymer as a main component and (ii) one or more anti-blocking agents.
