Abstract

(57) [Abstract] [Purpose] The present invention is to provide a packaging bag for packaging an insulating tape or the like which is used in a connecting portion of a cable and which does not like to absorb moisture. The present invention has a double bag structure, the inner bag 2 is made of a material having a high moisture permeability, the outer bag 3 is made of a material having a low moisture permeability, and the inner bag 2 and the outer bag 3 are combined. It is a packaging bag 1 having a hygroscopic agent 4 interposed between it, and the double structure of the bag itself and the increase in cushioning property due to the filling of the hygroscopic agent between the inner and outer bags reduce the risk of damage, resulting in high reliability. At the same time you get
Sufficient moisture absorption function is maintained for a long time by filling a sufficient amount of the moisture absorption agent.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging bag for packaging an insulating tape or the like which is used in a connecting portion of a cable and which does not like moisture absorption.

[0002]

[Prior art]

 Conventionally, when packaging insulating tapes that do not like moisture absorption as described above, this insulating tape is usually packed in a bag such as polyethylene together with a moisture absorbent (silica gel, calcium oxide, etc.) filled in a porous bag. The bag is closed and the mouth (opening) of the bag is sealed by fusion.

[0003]

[Problems to be solved by the device]

 However, in such a conventional bag having a single-layer structure, there is a problem in reliability, the bag material is likely to be scratched, and water may enter. If the water is continuously infiltrated, there is a limit in the relatively small amount of the hygroscopic agent that is contained in the porous bag, and there is a problem that it cannot be sufficiently dealt with. On the other hand, when the moisture absorbent is used in a multi-porous bag such as a paper material, some fine powder of the moisture absorbent itself spreads out of the bag and adheres to the insulating tape side. The problem arises. On the other hand, if a bag with a finer pore (pore) is used as the bag for the hygroscopic agent, then the moisture permeability will be reduced and good hygroscopicity will not be obtained.

The present invention has been made in view of such a conventional situation, and it is an object of the present invention to provide a packaging bag having a double bag structure, which has high bag reliability and sufficient hygroscopicity. is there.

[0005]

[Means for Solving the Problems]

 The present invention has a double bag structure in which the inner bag is made of a material having high moisture permeability, the outer bag is made of a material having low moisture permeability, and a moisture absorbent is provided between the inner bag and the outer bag. It is in a packaging bag characterized by containing.

[0006]

[Action]

 In the present invention, since the bag has a double structure, the cushioning property is increased, and even if an external force is applied to the insulating tape in the bag, the impact surface becomes two surfaces, the inner surface and the outer surface, and the bag is easily torn. High reliability is obtained. In addition, since the hygroscopic agent is widely and sufficiently filled between the inner bag and the outer bag, the hygroscopic agent itself contributes to the improvement of cushioning property, but on the other hand, if the outer bag is scratched or the like, it may continue to be damaged. Even if infiltration of water occurs, a stable moisture absorption function is maintained for a long time.

[0007]

【Example】

 1 and 2 show an embodiment of a packaging bag according to the present invention. In this packaging bag 1, 2 is an inner bag, 3 is an outer bag, 4 is a hygroscopic agent filled between the inner bag 2 and the outer bag 3, and T is the packaging bag 1 thus formed. It is the stored insulating tape.

The inner bag 2 is made of a material having high moisture permeability, such as polycarbonate (PC), and the outer bag 3 is made of a material having low moisture permeability, such as stretched polypropylene (OPP). , High density polyethylene (HDPE), low density polyethylene (LDP E), etc.

The specific structure of the two bags 2 and 3 is not particularly limited, but as shown in the figure, a structure in which the outer edge portions of the inner bag 2 and the outer bag 3 are fusion-bonded to each other may be used. In some cases, a hygroscopic agent 4 such as silica gel or calcium oxide is widely filled in the gap between the back and the front of the two bags 2 and 3.

Since the packaging bag 1 is formed in this manner, even if an external force acts on the insulating tape T housed inside as described above for some reason, first, the double structure of the bag itself and the Since the hygroscopic agent 4 made of powder is filled between the inner and outer bags, a very good cushioning function can be obtained and the bag can be effectively prevented from being damaged. Therefore, infiltration of water due to scratches can be prevented for a long period of time, and a highly reliable storage state can be realized. In addition, since the moisture absorbent 4 is wide and fully filled between the inner and outer bags, even if the outer bag is damaged and moisture continuously enters, the entire area of the bag is almost completely covered. Thus, a stable moisture absorption function can be obtained over a long period of time.

[0011]

[Effect of device]

 Thus, according to the packaging bag of the present invention, the inner bag is made of a material having a high moisture permeability, the outer bag is made of a material having a low moisture permeability, and the inner bag and the outer bag have a double bag structure. Since a hygroscopic agent is inserted between the bag and the bag, the double structure of the bag itself and the cushioning property due to the filling of the hygroscopic agent between the inner and outer bags reduce the risk of damage, resulting in high reliability. At the same time, it is possible to expect an excellent effect that has never been seen, such as maintaining a stable moisture absorbing function for a long time by filling a sufficient amount of the moisture absorbing agent.
