Abstract
A film that is excellent in easy cuttability and linear cuttability and suppressed in breakability in processing, and a roll and a pressure-sensitive adhesive tape that includes the film. The film has the tensile strength in one direction is 1.1 to 2.5 kN/m and the tensile strength in a direction orthogonal to the one direction is 3.0 to 10 kN/m, or the tensile strain at tensile strength in one direction is 50 to 150% and the tensile strain at tensile strength in a direction orthogonal to the one direction is 8 to 20%.
