Description

[Detailed Description of the Invention] The present invention relates to a packaging material for enclosing a desiccant for foods and the like.

BACKGROUND ART Conventionally, in order to prevent solid foods, etc. stored in bags, boxes, cans, etc. (hereinafter referred to as packaging containers) from becoming moist, desiccant agents wrapped in paper are generally stored in the packaging containers.

However, since the desiccant contains substances that are harmful to the human body, if the packaging material containing the desiccant is damaged during handling, the desiccant may come into contact with the human body and cause an unexpected accident. was there.

For example, quicklime is widely used as a desiccant because it is cheap, but when children accidentally break the packaging, the quicklime scatters and damages the mucous membranes of the body.
In particular, there was a risk that the liquid could enter the eye area, resulting in damage to the eye area and, in some cases, blindness.

Therefore, in recent years, there have been many calls for stronger packaging for this type of desiccant in the industry and among consumers, but the reality is that no effective product has yet appeared.

In view of the above-mentioned circumstances, this invention is designed to prevent children from playing with it.
The purpose of the present invention is to provide a packaging material for a desiccant that has features such as not being easily damaged, and in order to achieve this purpose, the structure of the present invention will be explained based on the illustrated embodiment as follows. It is as follows.

As shown in the figure, the present invention includes a packaging material 10 containing a desiccant 11 such as quicklime or silica gel.

That is, the packaging material 10 includes a breathable outer layer material 12 made of paper or a mixed paper of pulp and rayon, and an inner layer material in which vent holes 13 are formed at required intervals throughout the entire area of a heat-fusible plastic film such as polyethylene. 14, and these inner and outer layer materials 12.
14, and a reticulated intermediate layer material 15 of heat-melt compatible plastic interposed integrally by heat-sealing.

The net-like intermediate layer material 15 is made by stretching a heat-fusible plastic film under heat to arrange its molecules to improve its physical properties, and by splitting the film at required intervals over the entire area of the film. It is formed into a net shape by expanding the splits as appropriate.

The packaging material 10 of the present invention having such a configuration has an outer layer material 12.
The desiccant 11 is wrapped around the desiccant 11 so that the inner layer material 14 becomes the outer surface and the inner layer material 14 faces each other vertically, and the peripheral portion 16 thereof is heated under pressure to be fused and bonded together.

As described above, the packaging material 10 of the present invention includes an outer layer material 12 which is paper or a mixed paper of pulp and rayon, and a perforated inner layer material 14 made of a plastic film with a plastic mesh intermediate layer material 15 interposed on the inner surface thereof. Since it is formed by heat-sealing the outer layer material 10, the strength is significantly improved compared to using only paper or pulp and rayon mixed paper as the outer layer material 10, and the desiccant 11 is included. Below, the periphery of the packaging material 10 is fused and bonded together via an inner layer material 14 and an intermediate layer material 15, which prevents children or the like from playing with the desiccant 11 enclosed in the packaging material 10. Even if something happens, the packaging material 10 is easily damaged, or its surrounding joints are peeled off, and the desiccant 11 inside spills out and scatters, resulting in damage to the mucous membranes of the body, etc., as in the past. There is no danger of

Since the middle layer material 15 has a net shape and the inner layer material 14 has ventilation holes 13, even though these two layers are integrally bonded to the outer layer material 12, it is sufficient as a desiccant packaging material. It has excellent features such as being breathable, allowing the desiccant 11 to exert its effectiveness, and the weight of the packaging material 10 as a whole does not increase significantly compared to conventional packaging materials of this type.
