Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in a bag and a method for manufacturing the same, and more specifically, the first invention provides a transparent bag (^) with a label (2) printed on at least one side. The second invention relates to a bag characterized in that the label (2) is inserted from both sides to the other end, and both sides of the label (2) are thermocompressed or adhered to the bag (^). Print the required two bells (2) on at least one side of the tape (1) at regular intervals, fold a long transparent sheet for bags (3) in the longitudinal direction, and place between the folded sheets (3). Insert the tape (1) and label (2)
The peripheral portion of the label (2) and the cut portion (4) between the printed portions of the label (2) are bonded together by heat, and then the cut portion (4) of the sheet (3) is cut to form a bag. This occurs in relation to a bag body characterized by the formation of , and its manufacturing method.

In the conventional bag manufacturing method, first, a predetermined printing is performed on a part of a transparent bag sheet, and then the entire printed part or the peripheral part and the cut part between the printed parts are bonded by thermocompression.
Finally, the cut portions were cut to form individual bags.

When printing directly onto a transparent sheet as described above, even if the printed area is only a small area, not only the entire sheet must be prepared, but the entire printing process is required for each sheet. However, in the case of mass production of a small variety of products, printing costs were extremely high in the case of production of a large number of products in small quantities.

In addition, when printing on a transparent sheet for bags, when the label part is heat-pressed and made into a double layer, the core material is not sandwiched open, so the strength is weak, and conversely, the core material is In order to insert the label into the bag, it is necessary to construct the label portion into a bag and insert the labels one by one into the bag portion, which has the drawback of very poor workability.

The present invention was made in view of the drawbacks of the conventional example, and
The purpose is to provide a bag and its manufacturing method that can print a wide variety of labels at once, significantly reduce printing costs, have a strong label section, and are extremely easy to work with. There is something to do.

Hereinafter, the present invention will be described in detail according to illustrated embodiments.

The bag sheet (3) is a plain and transparent sheet made of polyethylene, vinyl chloride, etc., and
Depending on the type and purpose, various types of sheets, such as two types of sheets stacked on top of each other and biaxially stretched sheets, can be used as appropriate. Label (2) is a piece of synthetic paper (as shown in Figure 2).
5) Many types of printing are done at regular intervals,
Different types of printing will be performed for each column. Printing may be done on both sides of the synthetic paper (5) or on one side. If it is one side, it may be used by cutting it into tape (1) shape and folding it in two as described below. It is.

The thickness of the synthetic paper (5) can be selected arbitrarily. When the printing of the labels (2) is completed, the printed paper is cut out for each row, resulting in a long tape (1) on which the same type of labels (2) are printed.

Next, the long transparent sheet for bags (3) is continuously folded, and at the same time, the tape (1) is inserted between the folds. The folded pieces (3a) and (3b) of the transparent sheet for bags (3) have long and short lengths, and glue is applied to the lower edge of the longer folded piece (3b) to form an adhesive band (6). It will happen. In this state, heat-bond the transparent bag sheet (3)!
1lffi, and heat-press the entire label (2) or the peripheral portion of the label (2) and the cutting area between the labels (2). After that, cut out the bag body (^) one by one from the cut point. Similarly, other types of bags (^) are manufactured using the remaining tape (1).

Thermocompression bonding is effective when the adhered parts are of the same type of sheet, but the adhesive force is weak when the adhered parts are of different types, in which case tape (1) is used.
Liquid glue is evenly applied to both surfaces of the tape (1) and the sheet (3) are bonded together using the liquid glue.

Note that (7) is nine hanging holes provided in the label (2) portion. After storing food items and other items in the bag body (^), bend the protruding end of the longer folding piece (3b) and glue it to the lower edge of the shorter folding piece (3a). .

As mentioned above, in the first invention, a label printed on at least one side is sandwiched between one side end of the transparent bag body and the other side end, so that a long length with labels printed at regular intervals can be used. It has the advantage of being able to use tape, which greatly simplifies the bag manufacturing process.Since both sides of the label are heat-pressed or glued to the bag, the label becomes the core material and the label part It has the advantage of being reinforced, and PIS2
In the invention, required labels are printed on at least one side of a length of tape at regular intervals, a long transparent sheet for bags is folded in the longitudinal direction, and the tape is sandwiched between the folded sheets. Because it is packed in one bag, it is possible to eliminate the time-consuming work of manually inserting labels one by one, which greatly simplifies the bag manufacturing process, and there is no need to print directly on the sheet. Therefore, it is not necessary to print the entire sheet, let alone the printing of the entire sheet, and the printing part can be limited to the label housing, which can significantly reduce packaging costs in the case of small volume production. It has the advantage of being possible. Furthermore, since the label portion or the peripheral edge portion of the label is thermocompressed or bonded, there is an advantage that the label serves as a core material and the label portion is reinforced.
