In FIG. 1, the bag base paper is composed of, for example, an inner layer paper 1 and an outer layer paper 2 of kraft paper, and these are superimposed and continuously fed from a driving roll 3 and a driven roll 4 as a feeding mechanism. In the meantime, window holes 6 of an arbitrary shape (for example, an elliptical shape) are opened at predetermined intervals in the inner layer paper 1 and the outer layer paper 2 running at predetermined intervals by a perforation device 5, and the inner and outer layer papers 1 and 2 having the window holes 6 are separated. It is once separated by the rolls 7 and 8 as mechanisms.

At this time, the transparent film 9 has a width of about の of the base paper so that the transparent film 9 is supplied only to the front body of the bag, that is, the body on the side of the window. In addition, the paste is applied to the outer layer paper 2 in a pattern such as a line or a dot by the paste roll 10a, and the paste is applied to the inner layer paper 1 in a pattern like the outer layer paper by the paste roll 10b.

A bottom portion is formed at one opening end of the cylindrical body A by a bottommer (not shown) to form a bag with a window hole. If necessary, a tie string 13 (some of which is also used as a hand-carrying string) is appropriately attached to the opening for entering and exiting the product.

【発明の効果】上述した方法で製造された袋は、前胴部
に透明フィルムで塞がれた透視窓があるので、消費者は
袋の中の商品を外部から見ることができ、収納商品の品
質等を目で見て調べることができる。The bag manufactured by the above-described method has a see-through window closed with a transparent film on the front body, so that the consumer can see the product in the bag from the outside and store the product. The quality of the product can be checked visually.

【００１４】また、前胴部だけではあるが内外層紙間に
透明フィルムが介在しているので、それだけ全体として
強度の高い袋となっている。Further, the transparent film is interposed between the inner and outer layer papers only in the front trunk portion, so that the overall strength of the bag is high.

大量生産できる工業上の利点がある。Further, in the method of the present invention, a window hole is formed in the inner and outer layer papers. Since the window hole can be formed in a state where the inner and outer layer papers are overlapped with each other, only one punching step is required. The holes in the outer layer paper coincide with each other, and it is not necessary to position the holes differently from the case where the holes are individually formed in the inner and outer layer papers, and the window holes can be formed accurately and efficiently. In addition, the manufacturing process can be performed in a series of flow operations, and there is an industrial advantage that mass production can be performed efficiently.
