As shown in FIG. 8 and FIG. 9 which is a cross-sectional view taken along the line NN of FIG. 8, this bag A is formed by folding and welding a flexible synthetic resin film as a whole. It is formed in a rectangular shape. More specifically, the film is folded in two at the bottom 11 of the bag portion 1 of the bag body A, and the two films are joined by welding at the left and right edge portions 12 and 13. Of the edges of the opening 14 of the bag portion 1 through which the product is put in and taken out, an extension piece 2 is integrally and continuously provided on the back edge, and this extension piece 2 is provided. The intermediate portion 21 of the extension piece 2 is welded to the base 22 of the extension piece 2 in front of the opening 14 by welding (the welded portion is indicated by a symbol W). At the same time, a paper core 3 made of elongated strip-shaped paper is sandwiched between the two folded portions so as not to move. Further, in the extension piece portion 2, a portion further extending from the welding position W is the opening / closing piece 4. An adhesive portion 5 coated with an adhesive is formed in a strip shape over the entire width of the front side portion of the bag portion 1 near the opening 14, and peels off the adhesive portion 5 when the bag body A is not used. A piece 6 is attached, and the opening / closing piece 4 is overlapped on the peeling piece 6 and covers the opening 14 of the bag 1. Further, the adhesive portion 5 may be formed between the opening / closing piece 4 and the peeling piece 6 (that is, either the opening / closing piece 4 or the peeling piece 6). Reference numeral 7 denotes a hole opened between the extended piece 2 of the bag 1 and the paper core 3, and this hole 7 is used, for example, when hanging the bag A on a display shelf.

For this reason, when the synthetic resin film forming the bag portion 1 and the opening / closing piece 4 is transparent, a striped pattern or a spot is formed at the bonding portion between the bag portion 2 and the opening / closing piece 4 via the adhesive portion 5. Patterns often appear and become unsightly. On the other hand, as described above, it was troublesome to perform a series of procedures of putting a product in the bag portion 1 of the bag body A and closing the opening 14 of the bag portion 1 with the opening / closing piece 4. There was a demand for a little more simplification.

Further, when taking out the product put in the bag A, the bag A itself is not easily broken due to the use of a durable synthetic resin film, and requires considerable force, especially for children and the elderly. However, there is a problem that recent plastic film bags are difficult to break.

The present invention has been made in order to cope with the above circumstances, and by devising a place where an adhesive portion is provided, a stripe pattern or a spot pattern appears at a portion where the opening / closing piece and the adhesive portion are bonded. It is an object of the present invention to provide a bag body that does not make the bonded portion unsightly. In addition, this invention eliminates the need to fold the opening / closing piece and open the opening of the bag at the initial stage when putting the product in the bag. It is an object of the present invention to provide a bag in which a series of work procedures until the mouth is closed with an opening / closing piece is simplified. Another object of the present invention is to provide a bag that can be easily taken out with a small force, even if the bag is made of a strong synthetic resin film.
