Surface protective film and method for manufacturing organic light-emitting electronic device by using same

A surface protective film comprising:

• a base layer sequentially comprising a first anti-static layer, a base film, and a second anti-static layer;
• and
• an adhesive layer provided on a surface of the second anti-static layer, which is opposite to a surface on which the base film is provided,
• wherein the surface protective film satisfies Equation 1:
• (Adhesive Strength A)−(Adhesive Strength B)>0.5 gf/in <Equation 1>
• wherein, in the surface protective film, when a surface of the adhesive layer opposite to a surface on which the base layer is provided is defined as a first surface, and a surface of the base layer opposite to a surface on which the adhesive layer is provided is defined as a second surface,
• Adhesive Strength A is a peel strength when the first surface of the surface protective film is attached to glass using a 2 kg roller and the surface protective film is peeled off from the glass at 25° C., a peel speed of 2 m/min, and a peel angle of 180°, and
• Adhesive Strength B is a peel strength when the second surface of the surface protective film is attached to a drum pad using a 2 kg roller and the surface protective film is peeled off from the drum pad at 25° C., a peel speed of 2 m/min, and a peel angle of 180°.
