A plastic film bag with an air cushion has a bag body (14) composed of a front side (17a) and a back side (17b) made by folding a tubular material (11) which has a plurality of plastic film long cells (12) which are arranged and connected in parallel at substantially a center with respect to a direction of longer dimensions of the cells (12) and by fusing the folded portion at both sides (16), a flap (20) which is extended from an open end (18) of the back side of the bag body and which comprises a plurality of cells (21) which communicate with the cells (12) formed in the bag body, and air injection means (31, 32, 33) which is provided for the bag body to inject air into the cells (12, 21). When the cells are filled with air after an item (A) is contained in the bag body, the flap is pressed between the item contained in the bag body and the front side swollen with air, and the flap does not come out easily.
