fに他の物が引掛り易く、取り扱い性に問題がある。Conventionally, as shown in FIG. 1, a method for forming such a planned tear area is to open and close two tapes b, b at a predetermined distance on the bag body a, and align them with the direction of the tear direction of the bag body a. This method involves forming a cut d in the packaging body a as shown in FIG. Tape C over d
There is a known method in which the cut d indicated by -'f is set as the planned tearing area C, but these methods have problems such as the troublesome process of attaching tape to the bag. be. Also,
As shown in FIG. 3, a V-shaped notch f is formed at a predetermined edge of the packaging body a, and this notch is connected to the part to be torn C.
There is also a method called "cutting", and this method is especially easy to tear if the book binding a is formed using a plastic film with a unidirectional crystalline arrangement. It is easy to get caught and has problems in handling.

れを用いて包装装本体を形成することもできる。In this case, near-infrared rays may be irradiated in a continuous band form from one edge to the other edge in the width direction of the packaging material, as indicated by reference numeral 3a in FIGS. 5 to 7. The irradiation area 6 may be irradiated in a chain line pattern at appropriate intervals, or it may be irradiated partially at a predetermined edge of the packaging material in the same way as conventional cuts. good. Here, the irradiation width of near-infrared rays on the packaging material is:
It is preferable that the distance is 1 to 5 +++ m, and the irradiation bullet holes are 100 m per 1 d of packaging material, taking a Kibinon lamp as an example.
It is preferable to set it to 2000 Watts 1 to 300 to 600 Watts. Furthermore, the near-infrared irradiation time is 0.01
It is preferable to set the time to 5 seconds, particularly 0.1 to 1 second. In addition, it is preferable to perform the discharge treatment on the outermost layer of the packaging material (the side that will form the outer surface or surface of the packaging bag when the packaging bag is manufactured using this material), and particularly on the outermost layer of the packaging material. When applying direct infrared irradiation to the packaging body formed using It is also possible to use a composite film laminated with an irradiated film as an intermediate layer as a packaging material to form a packaging body.

きる。For example, if a bag is manufactured using a packaging material on which a near-infrared irradiation area has been formed in advance, a near-infrared irradiation area or a near-infrared Either wrap the packaging material that does not have a near-infrared irradiation area and heat-bond the necessary peripheral edges, or fold the packaging material that has formed the near-infrared irradiation part from the center and overlap it, and heat-bond the necessary peripheral edges. A method of thermally bonding the lower edge of the shield U and then the overlapping V, or thermally bonding a bottom forming material bent into a V-shaped cross section or an inverted V-shaped cross section to the lower edge of the stacking table, etc. is adopted. Ru. F43M like this next to figures 5-7.
This figure shows a bag with a near-infrared irradiation part (the part to be torn) placed at (Ω) in the center of the L part of this bag, Figures 5 and 7. It is possible to form a display part 7 that surrounds the near-infrared irradiated part (part to be torn) 3 of the sea urchin shown in J: and displays that this part should be torn.

り 。In this case, in the packaging bag manufactured by the method of the present invention, the planned tear portion is formed by near-infrared irradiation, and the packaging material is damaged by direct contact with the packaging material, such as by making VJ marks or making cuts. Unlike the method of "forming the planned tear area", since the packaging material is not directly damaged, a decrease in the strength of the planned tear area is prevented as much as possible. It is very easy to handle. Also, remove the contents stored inside.
