PROBLEM TO BE SOLVED: To assure easy unsealing by joining an unsealing tape on a cut provided orthogonally to a direction of a flow of a plastic film. SOLUTION: In the plastic film 1 for packing, a cut 3 provided orthogonally to a direction of a flow of a plastic film 2 comprises a cut 3a provided through the film 2 and a joint 3b coupled with the cut 3a uncut, which are alternately provided to constitute a chain line. An unsealing tape 4 is provided on the cut 3 to be joined along a direction with the cut 3 provided, wherein after it is joined on the plastic film 2, at least one end of the tape 4 protrudes from a widthwise side end of the film 2 to form a tab 4a. As a material of the unsealing tape 4, a thermoplastic resin as the same as the film 2 is used. Thus after unsealing after packing, the tab can be easily found for pulling it for unsealing.
