PROBLEM TO BE SOLVED: To provide a plastic bag which can be produced by utilizing existing facilities and has a nozzle-like opening, through which a fluid material can be taken out, and which can be resealed, while a zipper can be prevented from being clogged with the fluid material. SOLUTION: In the plastic bag, a nozzle-like pouch 21, which is made of a plastic film and has a zipper 30, is provided in a welded part C of a large bag 11 formed by welding plastic films. A welding inhibitive treatment is applied to the inner surfaces of the pouch 21 so that when the pouch 21 is welded to the welded part C, the inner surfaces of the pouch can be prevented from being welded. The pouch 21 can be pulled out of the large bag 11 by inserting fingers into the pouch 21 to turn out the inside thereof. The forward end of the pouch 21 pulled out of the bag 11 is cut off, thereby taking out the contents of the bag 11 from the cut portion of the pouch. After necessary amounts of the contents are taken out, the cut portion is closed by means of a clip and the cut portion is pushed into the pouch, and the zipper 30 is closed. |
