PROBLEM TO BE SOLVED: To provide a plastic bag the opening part of which can be easily sealed, and its manufacturing method. SOLUTION: A self-adhesion part (for example, pressure sensitive double faced adhesive tape) 14 with a peelable film 13 temporarily adhered thereto is provided on a portion forming an opening part 11 so that the self-adhesion part forms no obstacles in storing a commodity, etc., and can be easily sealed only by peeling the peelable film after the storage, exposing the self-adhesion part, and butting edges of the opening part to each other. In manufacturing a plastic bad out of a strip-like film, the plastic can bag be easily obtained at a low cost by providing the self-adhesion part with the peelable film temporarily adhered thereto in advance on a portion forming the opening part of a bag area. |
