Abstract

PROBLEM TO BE SOLVED: To supply moisture from a moisture-containing material to be stored in a bag by storing a roll-wound wall paper in a synthetic resin bag together with the moisture-containing material capable of discharging the moisture. SOLUTION: A raw glue is applied to a back side of a wall paper 1, and a polyethylene back side film of 20-30 μm in thickness is attached to a surface with the glue. The wall paper of 970 mm in width and 6 m in length is wound to form a roll of 80 mm in diameter. Then, a highly moisture-absorbing resin is stored in a small bag formed of non-woven textile to form a moisture- containing material 2 to be a moisture supply source. Before the moisture- containing material 2 is used, it is immersed in water for approximately 10 minutes in advance to absorb water in an approximately saturated condition. Finally, the wall paper 1 wound in a roll, the moisture-containing material 2 and a deoxidant material 4 for mold prevention are stored in a packaging body.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for packaging wallpaper and a package for wallpaper.

[0002]

2. Description of the Related Art In recent years, as wallpaper used for wall surface renovation, etc., in recent years, in many cases, a paste material has been applied to the back surface in advance so that the attaching operation becomes easy. In such a wallpaper, a back surface film is provided on the back surface of the paste material for protecting the paste material, and the back material is peeled off to expose the paste material when used. FIG. 2 is a cross-sectional view of such a wallpaper, in which (5) is a wallpaper, (6) is a glue material disposed on the back of the wallpaper (5), and (7) is a back film.

[0003] Due to its nature, wallpaper is stored in a bag-shaped container in a rolled state so as to be long and is distributed and sold.

[0004] Wallpapers may take nearly a year from the time they are shipped to the time they are sold and reach the user. Sticking to a wall may be difficult. In particular, both ends of the roll are easy to dry because the glue material comes into contact with air.

[0005] Therefore, if the product is sold after long-term storage, the quality of the product may be insufficient when the purchaser actually uses the product. At home centers developed in recent years, the inside of the store is air-conditioned so that customers can shop comfortably and it is a little dry throughout the year, so this effect is considered to be great, and prevention of wallpaper drying is a major theme as a manufacturer. Has become.

[0006] Under such circumstances, conventionally, the inside of the package is hardly dried by storing it in a bag-like package made of a synthetic resin that is not easily permeable to moisture and sealing it. However, even such a synthetic resin through which moisture is difficult to permeate cannot completely prevent the permeation of moisture, and the moisture in the package is gradually released to the outside, and the package dries. Therefore, it has not been possible to sufficiently prevent the glue material from being dried during long-term storage.

In order to prevent the permeation of water, it is also conceivable to store in a bag-like package made of a metal sheet. However, since the metal sheet is not transparent, the pattern of the stored wallpaper can be removed from the outside of the package. It cannot be confirmed, which is not preferable in terms of product management and sales.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a packaging method and a packaging body for keeping a sufficient quality of a wallpaper product for a long period of time without drying the glue material even when stored for a long period of time. The purpose is to provide.

[0009]

According to a first aspect of the present invention, there is provided a method of packaging a wallpaper, comprising the steps of: combining a rolled wallpaper (1) with a water-containing material (2) capable of releasing moisture; It is stored in the body (3).

[0010] According to this, even if the moisture inside the bag passes through the outside of the bag, the moisture is supplied from the water-containing material stored in the bag, so that the bag is hard to dry.

As the water-containing material (2), wood materials, paper materials, woven fabrics, non-woven fabrics, rock wool, sponges and the like, and the highly water-absorbing resin described in claim 2 can be used.

According to a second aspect of the present invention, in the method for packaging a wallpaper according to the first aspect, a highly water-absorbent resin which has been previously absorbed by water is used as the water-containing material (2).

The superabsorbent resin has a property of absorbing moisture and retaining the absorbed moisture so that it does not immediately escape (do not flow backward). However, the inventor paid attention to the fact that water escaped from the superabsorbent resin little by little in the state of absorbing water, and considered using this as a water-containing material. In other words, the idea of a highly water-absorbent resin originally used for absorbing moisture is completely reversed, and water is absorbed in advance, so that it is used as a water supply source.

According to this, since the water can be gradually released from the superabsorbent resin which is close to the saturated state for a considerably long period of time, the bag can be kept moist for a long period of time.

According to a third aspect of the present invention, there is provided a wrapping material for a wallpaper, wherein the wrapping material is a synthetic resin bag (3) capable of storing a rolled wallpaper (1) and hardly allowing moisture to pass therethrough. And a water-containing material (2) capable of releasing moisture. By using this, the method for packaging wallpaper according to claim 1 can be implemented.

According to a fourth aspect of the present invention, there is provided a wallpaper packaging body according to the third aspect, wherein the water-containing material (2) is a highly water-absorbing resin in a water-absorbing state. By using this, the method for packaging wallpaper according to claim 2 can be implemented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to preferred embodiments. [Embodiment 1] FIG. 1 is a view showing a package of the present embodiment in which wallpaper wound up in a roll is stored. In the figure, (1) is a wallpaper wound in a roll shape, which is provided with raw glue on the back surface, and is further provided with a 20-30 μm polyethylene back film on the glue surface, which is 970 mm wide and 6 m long. And a roll having a diameter of 80 mm.

(2) is a water-containing material serving as a water supply source,
In this embodiment, the superabsorbent resin (crosslinked polyacrylate,
Arakawa Chemical Industry Co., Ltd .: Product name “ARASORP S-31”
0 ") in a non-woven pouch. Before use, the product is immersed in water for about 10 minutes and absorbed until almost saturated. By the way,
The superabsorbent resin, which was 1 g in a dry state, became 5 g after absorbing water.
It was 8 g. (4) is a deoxidizing material for preventing mold.

Then, the wallpaper (1), the water-containing material (2) and the deoxidizing material
(4) is stored in a 1150 × 190 mm KPET bag (2) having a thickness of 60 μm and sealed, and 5 sets of wrapped wallpaper (A1 to A)
5) Created. The space volume in the bag (2) excluding the wallpaper (1) and the like was about 400 cc. In the present embodiment, the water-containing material is simply placed in the bag, but may be inserted into the axis of the roll core.

In order to adjust the degree of release of water from the superabsorbent resin, it is conceivable to change the type and amount of the superabsorbent resin. It can also be adjusted using. For example, changing the coarseness of the nonwoven fabric used as the material of the sachet, making one surface of the sachet a poorly breathable resin film, making the entire sachet a resin film, and providing small windows such as a nonwoven fabric for ventilation. You may. In particular, when mounting inside the roll core shaft, use a small bag made of resin film on one side, and stick the resin film surface inside the roll core shaft with double-sided tape. As described above, the transfer to the roll core shaft can be prevented.

[Comparative Example] Wallpaper was stored in a bag and sealed under the same conditions as in the example except that no water-containing material was used.
Sets (B1 to B5) were created.

[Comparative Test] The Examples and Comparative Examples were opened 70 days after the start of the test, and the state of the wallpaper inside was compared and observed. Table 1 shows the water content at each of the start (winding inside the roll) and the end (outside roll) of the five sets of examples. Similarly, Table 2 shows the water content of each of the five sets of comparative examples at the start (roll inside) and at the end (roll outside).

[0023]

[Table 1]

[0024]

[Table 2] In a test of only 70 days, it is clear that the wallpaper wrapped with the present invention has a higher moisture content than the wallpaper wrapped by conventional wrapping means without water-containing material. You can see that.

Further, even after the test is completed, the superabsorbent resin used in the examples sufficiently retains moisture, and it is considered that a sufficient moisturizing effect is exhibited even after long-term storage.

In the embodiment, the superabsorbent resin is used as the water-containing material. However, wood material, paper material, woven fabric, nonwoven fabric, rock wool, sponge, etc. may be used. The superabsorbent resin that can be used in the present invention is not limited to those of the examples, and is typified by, for example, polyacrylates, polyvinyl alcohols, maleic anhydride and other non-polymers, polyethers, and condensation systems. Highly water-absorbing resins such as synthetic polymers, starches, celluloses, other polysaccharides, and proteins such as collagen can also be used.
