ずれも好ましい状況ではない。(1) Prior Art At present, a thin vinyl film tube is formed by a well-known method called blown film molding, and the thin vinyl film tube is made into a flat sheet as shown in Figure 1. After drilling holes perpendicular to the direction of the tube, weld them parallel to the chain-line perforations near one hole of the chain-line perforation, and use the resulting tube sheet as a double-rolled plastic bag. However, by making plastic bags thinner and reducing the amount of plastic used, °
Due to efforts to reduce costs, the reality is that plastic bags are stuck together and cannot be opened, and it takes time to put items into the bags, reducing efficiency in factories that have a bagging process. Due to the deterioration, costs such as personnel expenses will increase, and retail stores and
This has led to a stagnation in customer traffic at supermarkets, which is not a favorable situation.

lfl, the cutout part (21+3) has a zigzag shape,
The upper cutout part (2) has a structure that does not completely overlap the lower cutout part (3), and the vicinity of the cutout parts f2 and f31 is welded. That is, the tube sheet (7) shown in FIG. 3 is placed in such a state that the perforated concave portion of the upper cutout portion (2) overlaps with the perforated convex portion of the lower cutout portion (3), and the vicinity thereof is welded. This is what I did.

Then, perforations (8) are made in a zigzag pattern in a direction perpendicular to the direction of the tube sheet (7), as shown in FIG. This perforated hole (8) I/'i is made simultaneously on the upper and lower sides of the tube 7-t, and then the tube 7-t (7) is opened in the direction of the arrow as shown in Fig. 3. The perforations (8) are cut out (2) as shown in Figure 2.
(4). [This welded portion is shown and is a method of manufacturing a tube sheet that is finally wound up on a winding roll (23) shown in FIG. 4.

チューブ７−ｔ（１７）の厚ざについても同様である。Perforated holes (8) as shown in FIG. 3 are made in the flattened tube sheet (14) by means of a perforation device (20). Thereafter, the tube sheet (15) with the perforations (8) inserted therein is pulled by the winding opening and moved to the shifting device (21). The welded tube sheet (17) is welded by a shifting device (21) so as to have a groove (4) so that the convex part of the cut-out capital (5) does not overlap with the convex part of the cut-out capital (5). )
D. The distance between the tube sheet (17) and the width of the tube sheet (17) can be determined by a mechanical mechanism that can be easily designed by a person skilled in the art, taking into consideration the purpose and use of the bag. All you need to do is decide on the size and length, and
The same applies to the thickness of the tube 7-t (17).
