Description

  The present invention relates to a packing material for an industrial product that protects the industrial product from being damaged during a physical distribution process.

  In recent years, so-called sick house syndrome, which causes headaches and dizziness in newly built houses, has become a problem, and chemical substances such as formaldehyde have been cited as causative substances. Since these chemical substances are volatile organic compounds generated from building materials, paints, etc., the Ministry of Health, Labor and Welfare has given the indoor concentration of volatile organic compounds (hereinafter referred to as VOC) for each compound such as formaldehyde, toluene, and styrene. A guideline value and a guideline value for the indoor concentration of total volatile organic compounds (hereinafter referred to as TVOC) obtained by statistically calculating these VOCs have been submitted as guidelines.

  Therefore, in the housing-related field, building materials and paints that do not generate volatile organic compounds are used, or interiors that absorb volatile organic compounds even if they are generated are used to increase the indoor concentration of VOC and TVOC. We are reducing.

  On the other hand, as an example of an industrial product, in an image forming apparatus such as an electrophotographic printer or a copying machine used in an office or the like, ozone is generated by air discharge in a charging process of a surface of a photosensitive drum and a transfer process to a recording material. Or an organic compound such as styrene is generated by heating the toner in the fixing process to the recording material. For this reason, in order to prevent these organic compounds from being discharged out of the image forming apparatus as they are, an air filter is provided in the in-machine air passage to positively adsorb organic compounds, improvements to the charging process and transfer process, and There is a model in which the amount of organic compounds generated is reduced by improving the toner (for example, see Patent Document 1).

  However, in addition to the organic compounds generated by the image forming process as described above, the image forming apparatus is volatile even when the image forming apparatus is in a stationary state from components constituting the image forming apparatus, such as an exterior, an electric substrate, and various rollers. Of organic compounds may occur. In particular, since an image forming apparatus in a packaged state immediately after purchase is stored and transported in various environments for a long time in a substantially sealed state, the image forming apparatus may be filled with various volatile organic compounds. There may be a strange odor when unpacking.

  Since the unpleasant odor at the time of unpacking is a state before the image forming apparatus is energized, the effect of the air filter cannot be expected. In addition, it is possible to energize the image forming apparatus immediately after unpacking and start the fan to adsorb the organic compounds by the air filter. However, the volatile organic compounds filled in the image forming apparatus leak through the air filter. In order to remove them completely, a filter having a high removal ability per unit time must be used. For this reason, there is a concern that the product will become large and expensive. Of course, in the case of a model without an air filter, there is no choice but to wait for a natural decrease due to diffusion.

In the above description, the image forming apparatus has been described as an example of an industrial product. However, the same problem exists in, for example, home appliances and personal computers (hereinafter referred to as “PC”).
JP-A-6-19263

  An object of the present invention is to greatly reduce the emission of volatile organic compounds when unpacking an industrial product in a packaged state, for example, packing of an industrial product that can greatly suppress the generation of a strange odor during unpacking. Is to provide materials.

  The above object is achieved by the packing material for industrial products according to the present invention. In summary, the present invention relates to an industrial product packing material for packing an industrial product in a physical distribution process, wherein the packing member constituting the packing material has an adsorptivity for adsorbing a volatile organic compound. Packaging material.

  ADVANTAGE OF THE INVENTION According to this invention, the divergence of the volatile organic compound at the time of unpacking the industrial product of a packing state can be suppressed significantly, for example, generation | occurrence | production of the off-flavor at the time of this unpacking can be suppressed significantly.

  Hereinafter, the packing material for industrial products according to the present invention will be described in more detail with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention only to those unless otherwise specified. .

Example 1
In this embodiment, the present invention is applied to a packaging material for an image forming apparatus as an industrial product.

(1) Image Forming Apparatus As an example of an image forming apparatus, a schematic configuration of a laser beam printer (hereinafter referred to as “image forming apparatus”) using an electrophotographic system is shown in FIG.

  The image forming apparatus 1 includes a paper feed cassette 2, a paper feed roller 3, separation / conveyance rollers 4 a and 4 b, and a registration roller 6 as a recording material storage unit that stores a sheet (recording material) S. An upper part of the sheet feeding cassette 2 is located in the approximate center of the apparatus, and is an image forming process unit (hereinafter referred to as “hereinafter referred to as“ photosensitive drum ”) 7a formed in a cartridge including a cylindrical electrophotographic photosensitive member (hereinafter referred to as“ photosensitive drum ”). Process cartridge "). A transfer roller 8 is arranged below the photoconductive drum 7a and facing the photoconductive drum 7a, and a laser scanner 10 is arranged above the photoconductive drum 7a. Further, the image forming apparatus 1 includes a fixing device 9, paper discharge rollers 11 a and 11 b, and a paper discharge tray 12. The sheet S is conveyed through the conveyance path 5.

  Next, the operation of the image forming apparatus 1 configured as described above will be described.

  The sheets S stored in the paper feed cassette 2 are separated and fed one by one by the paper feed roller 3 and separation / conveyance rollers 4 a and 4 b, and conveyed to the registration roller 6. The registration roller 6 corrects the skew of the sheet S and resumes feeding at a predetermined timing.

  The photosensitive drum 7a of the process cartridge 7 serving as an image forming unit is uniformly charged by a charging unit (not shown) and then exposed to a laser beam from a laser scanner 10 serving as an exposure unit. A latent image is formed on the drum 7a. Next, a toner image is formed on the photosensitive drum 7a by attaching toner to the latent image by developing means (not shown). The formed toner image is transferred to the sheet S by the transfer roller 8 serving as transfer means.

  The sheet S on which the toner image is transferred by the process cartridge 7 is conveyed to a fixing device 9 as fixing means by the conveying force of the photosensitive drum 7 a and the transfer roller 8. The sheet S is applied with heat and pressure by the fixing roller and the pressure roller of the fixing device 9. As a result, the toner image is fixed on the sheet S. The sheets S that have passed through the fixing device 9 are sequentially discharged (output) and stacked on the discharge tray 12 via the discharge rollers 11a and 11b. Further, a cleaning means (not shown) for cleaning the photosensitive drum 7a after the toner image is transferred to the sheet S may be provided.

  In this embodiment, the photosensitive drum 7a, the charging unit, the developing unit, and the cleaning unit are integrated into the image forming apparatus main body A as the process cartridge 7, but are not limited thereto. For example, at least one of the photosensitive drum 7a, the charging unit, the developing unit, and the cleaning unit may be formed into a cartridge and may be an image forming process unit that can be attached to and detached from the image forming apparatus main body A.

(2) Packaging Material of Image Forming Apparatus FIG. 2 shows a schematic configuration of the packaging material of the image forming apparatus 1. As shown in FIG. 2, the image forming apparatus 1 has four corners on the upper surface and the lower surface of the image forming apparatus 1 so as to prevent the apparatus from being damaged even when an impact such as a drop during distribution is applied. Is packaged in a cosmetic box 21 in a state where it is protected. In other words, in this embodiment, the image forming apparatus 1 is disposed outside the image forming apparatus 1 and used as a packaging material for protecting the image forming apparatus 1 so that the image forming apparatus 1 is not damaged during the distribution process. A cosmetic box 21 that is an outer packaging material that covers the outermost part, and a buffer material 22 that is disposed between the cosmetic box 21 and the image forming apparatus 1 and absorbs an impact applied to the image forming apparatus 1 in the physical distribution process.

  The cushioning material 22 can be formed of a cushioning member such as polystyrene foam, cardboard, or pulp mold as a packaging member. In the present embodiment, the impact material 22 is made of expanded polystyrene.

(3) External packaging material (decorative box)
In the present embodiment, the cosmetic box 21 is basically composed of cardboard that is a packing member that is inexpensive and has a cushioning property that does not damage parts and the like. And in a present Example, the cardboard which comprises this decorative box 21 has the adsorptivity of a volatile organic compound.

  In this embodiment, as shown in FIG. 3, by providing an adsorption layer 32 containing a material (adsorbent) having adsorbability of a volatile organic compound on the surface of the cardboard 31, the adsorbability of the volatile organic compound is improved. Apply to the cosmetic box 21. In other words, in the present embodiment, the decorative box 21 is configured by an adsorbing layer-equipped packing member 30 </ b> A formed by forming an adsorbing layer 32 containing an adsorbent on the cardboard 31. The adsorbent layer 32 is provided at least on the inner surface of the cosmetic box 21, that is, on the surface facing the image forming apparatus 1 that is a packaged body.

  Thus, by providing the adsorption layer 32 on the inner surface of the decorative box 21 that covers the entire exterior of the image forming apparatus 1, volatile organic compounds generated during distribution can be adsorbed over a wide range, and volatile during unpacking. It is possible to effectively suppress the divergence of the organic compound and to effectively remove, for example, the off-flavor felt by the operator when unpacking. A much greater effect can be obtained than when a bag containing the adsorbent is left alone in the apparatus or in the decorative box 21.

  In addition, adsorbent adsorbs a certain amount of volatile organic compounds. Not only does the adsorbing performance deteriorate, but the adsorbed volatile organic compounds are easily removed due to an increase in ambient temperature or concentration of volatile organic compounds. Become. Also from this, unlike the case where the adsorbent is left in the image forming apparatus 1 or the decorative box 21 with a bag or the like, the adsorbent is adsorbed on the decorative box 21 that covers the entire exterior of the image forming apparatus 1 as in this embodiment. If the configuration is such that the image forming apparatus 1 is unpacked and the adsorbent is not forgotten when the image forming apparatus 1 is installed, problems such as separation of the adsorbate can be prevented.

  FIG. 4 shows another method for imparting adsorbability of volatile organic compounds to the cosmetic box 21. In the example shown in FIG. 4, the corrugated cardboard 31 constituting the decorative box 21 has a structure in which an adsorbent 33 containing an adsorbent having adsorbability for volatile organic compounds is embedded therein. An air hole 34 is provided on the surface of the corrugated cardboard 31 facing the image forming apparatus 1 which is a packaged body. Thereby, it is comprised so that the air which the cardboard 31 faces and the adsorbent 33 which the cardboard 31 encloses can contact. That is, in another method of the present embodiment shown in FIG. 4, the decorative box 21 is composed of an adsorbent-containing packing member 30 </ b> B including an adsorbent 33 containing an adsorbent.

  By adopting such a configuration, the volatile organic compound contained in the atmosphere facing the cardboard 31 is adsorbed by the adsorbent 33 contained in the cardboard 31, and the decorative box is provided by the packing member 30A with the adsorbing layer shown in FIG. The same effect as in the case of configuring 21 can be obtained.

  In addition, the method of providing the adsorptivity of the volatile organic compound to the cosmetic box 21 is not limited to the two methods described above. For example, a method of adsorbing the volatile organic compound from the side facing the packaged body in a state where the packaged body is packed, such as a method of dispersing the adsorbent in the cardboard material and forming it, is adopted. Can do. Moreover, although the present Example demonstrated the cardboard box as an example, the material of the box 21 is not limited to this. For example, any material can be appropriately used as long as it has an adsorptivity of a volatile organic compound by providing an adsorbing layer containing an adsorbent or an adsorbent as described above.

(4) Adsorbent of volatile organic compound The adsorbent of the volatile organic compound is any material that can adsorb the volatile organic compound, which is likely to be generated from the industrial product that is the package, to a desired extent. May be. A commercially available deodorant material (adsorbent) can be used as appropriate.

  As such a volatile organic compound adsorbent, porous materials such as activated carbon, silica gel, alumina, sepiolite, and zeolite can be preferably used. Further, the adsorbent may be any granular or fibrous substance having adsorbability.

  In addition, as a volatile organic compound adsorbent, one material selected from the porous materials including activated carbon, silica gel, alumina, sepiolite, and zeolite is suitable for the volatile organic compound generated from the package. However, when there are multiple types of volatile organic compounds generated from the package, multiple types (two or more types) may be used in combination according to the suitability of each substance. I do not care. In this example, activated carbon, which is a porous material, was used as an adsorbent for volatile organic compounds.

  In addition, as a method of forming the adsorbing layer 32 containing the adsorbent (in this embodiment, activated carbon) on the packing member 30A with the adsorbing layer formed by the decorative box 21, the surface is held using a fibrous adsorbent. There are a method, a method in which a granular adsorbent is dispersed in a paint, and a film is coated on the surface. However, as long as the adsorption performance of the volatile organic compound as the adsorbent is not significantly reduced, the method for applying the adsorbent to the packaging member is not particularly limited.

Further, the amount of the adsorbent used can be appropriately selected according to the configuration / size of the industrial product as the package, the desired removal level of the volatile organic compound, and the like.
(5) Comparative experiment An image forming apparatus packed with a packing material capable of adsorbing a volatile organic compound as in this embodiment and a packing material that does not specifically adsorb a volatile organic compound as in the conventional example. The packaged image forming apparatus was subjected to a standing test in which it was left for 10 days in an environment of a temperature of 23 ° C./humidity of 50% RH and a temperature of 50 ° C./humidity of 95% RH in a packaged state as a physical distribution test. Then, when the image forming apparatus after the leaving test was unpacked and installed, a sensory test was performed to evaluate whether or not a strange odor was produced. Here, the decorative box 21 is prepared so that the adsorption layer 32 is disposed on substantially the entire surface facing the image forming apparatus in the assembled state.

  These results are shown in Table 1. In the table, “◯” indicates a level at which no strange odor is felt, “Δ” indicates a level at which a slight odor is felt but no concern, and “×” indicates a level at which unpleasant odor is felt.

  From this comparative evaluation, as in this example, by giving the packaging material adsorptive properties of volatile organic compounds, even when left in a high temperature environment for a long period of time, for example, in a substantially sealed state as during distribution. It was confirmed that volatile organic compounds that may be generated from the image forming apparatus can be adsorbed and deodorized.

  As described above, according to this embodiment, the decorative case 21 is configured by the packing member 30A with the adsorption layer provided with the adsorption layer 32 on the inner surface, or the packing member 30B with the adsorbent containing the adsorbent 33. By covering and packing the entire image forming apparatus 1 with the decorative box 21, volatile organic compounds generated during the physical distribution process can be adsorbed. For this reason, the volatile organic compound in a packing box (decoration box) can be reduced, the divergence of the volatile organic compound at the time of unpacking can be suppressed effectively, for example, the bad smell felt at the time of unpacking can be prevented. In addition, by providing the cosmetic box 21 covering the image forming apparatus 1 with adsorbability for adsorbing volatile organic compounds, the volatile organic compounds generated during the distribution process can be reduced without increasing the size of the image forming apparatus 1 itself. It can be adsorbed over a wide range, and for example, the generation of malodor due to volatile organic compounds during unpacking can be greatly suppressed.

Example 2
Next, a second embodiment of the present invention will be described. In the present embodiment, as in the first embodiment, the present invention is applied to a packaging material for an image forming apparatus as an industrial product. The configuration of the image forming apparatus 1 is the same as that in the first embodiment, and the packaging form of the image forming apparatus 1 is substantially the same as that in the first embodiment. Accordingly, elements having substantially the same or corresponding functions and configurations as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, in addition to or instead of the cosmetic box 21 described in the first embodiment, the adsorbability of the volatile organic compound on the buffer material 22 that protects the four corners of the upper surface and the lower surface of the image forming apparatus 1. Is granted. Thereby, the volatile organic compound generated in the packing box (decorative box) is adsorbed.

  More specifically, in this embodiment, as shown in FIG. 5, the cushioning material 22 is basically configured by stacking cardboards that are packing members and bonding them together. The buffer material 22 has a fitting portion 22 a that matches the shape of the corner of the corresponding image forming apparatus 1. FIG. 5 shows only one buffer material 22 that fits into one corner of the image forming apparatus 1, but the other buffer materials 22 have substantially the same configuration.

  In this embodiment, the cardboard 31 constituting the cushioning material 22 is the same as the packing member 30A with the adsorbent layer shown in FIG. 3 described in the first embodiment or the packing member 30B with the adsorbent shown in FIG. In addition, the adsorption layer 32 is formed on the surface, or the adsorbent 33 is included. When the adsorption layer 32 is provided on the surface of the cardboard 31, the adsorption layer 32 may be provided on either one side or one side of the cardboard 31, but is provided on the surface facing at least when the cushioning material 22 is formed. It is preferable. Of course, like the first embodiment, the cardboard 31 may be provided with adsorptivity of volatile organic compounds by other methods.

  In the present embodiment, the cardboard cushioning material 22 has been described as an example. However, for example, as described above, an adsorbing layer containing an adsorbent or an adsorbing material is provided to provide an adsorbing property for volatile organic compounds. If it does, you may comprise the shock absorbing material 22 with the packaging member of other materials, such as a polystyrene foam and a pulp mold, for example.

  When a comparative test similar to that in Example 1 was performed for the case where only the buffer material 22 had the adsorptivity of the volatile organic compound, as in Example 1, an unpleasant odor was produced as compared with the case where the conventional packing material was used. The feeling level was greatly reduced. By using it in combination with the decorative box 21 that has the adsorptivity of volatile organic compounds, the level at which an unpleasant odor is felt during unpacking can be more effectively reduced. In addition, the buffer material 22 was created so that the adsorption layer 32 might be exposed outside by the same packaging member 30A with an adsorption layer as that used in the comparative test of Example 1.

  As described above, according to the present embodiment, in addition to or instead of the configuration for imparting the adsorptivity of the volatile organic compound to the cosmetic box 21, it is disposed between the image forming apparatus 1 and the cosmetic box 21. By giving the buffer material 22 adsorptivity of volatile organic compounds, the volatile organic compounds generated in the packing box (decoration box) are reduced, and the emission of volatile organic compounds during unpacking is effectively suppressed. For example, it is possible to prevent an unpleasant odor when unpacking. In particular, the adsorption property of the volatile organic compound can be further enhanced by imparting the adsorption property of the volatile organic compound to the buffer material 22 in addition to the decorative box 21. Further, by providing the buffer material installed between the image forming apparatus 1 and the decorative box 21 to absorb the impact during physical distribution, the adsorbing property to adsorb the volatile organic compound can be provided without increasing the size of the industrial product itself. The volatile organic compound generated during the distribution process can be adsorbed over a wide range, and for example, the generation of malodor due to the volatile organic compound during unpacking can be greatly suppressed.

  The configuration of the cushioning material is not limited to that of the present embodiment as long as it is disposed between the image forming apparatus and the decorative box and has a function as a shock absorbing member during distribution. For example, the cushioning material is not limited to being fitted to the corner of the packaged body, and may be fitted to the entire upper surface and / or lower surface of the packaged body, for example. Further, as in Example 1, the material of the buffer material, the method of imparting adsorptivity, and the material of the adsorbent are not limited at all.

Example 3
Next, a third embodiment of the present invention will be described. In the present embodiment, as in the first and second embodiments, the present invention is applied to a packing material for an image forming apparatus as an industrial product. The configuration of the image forming apparatus 1 is the same as in the first and second embodiments. Accordingly, elements having substantially the same or corresponding functions and configurations as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, in addition to or in place of the decorative box 21 described in the first embodiment and / or the cushioning material 22 described in the second embodiment, components in the apparatus are arranged so that the image forming apparatus 1 is not damaged during the physical distribution process. The adsorbability of the volatile organic compound is imparted to the holding member to be fixed. Thereby, the volatile organic compound generated in the packing box (decorative box) is adsorbed.

  More specifically, it is possible that the engaging portion of the image forming apparatus main body A and the process cartridge 7 may be damaged or the photosensitive drum 7a may be deteriorated by being dropped or vibrated during distribution and being left in a bad environment for a long time. Therefore, in this embodiment, the image forming apparatus 1 is packed in the image forming apparatus main body A with the process cartridge 7 not attached.

  However, when the process cartridge 7 is not mounted in the image forming apparatus main body A, the transfer roller 8 and the sheet S conveyance guide (not shown) normally held by the process cartridge 7 cannot be fixed. There is a possibility that it may come off or be damaged due to dropping or vibration. Therefore, in the image forming apparatus main body A to be packed, as shown in FIG. 6, a holding member 23 that holds and fixes the transfer roller 8 and a conveyance guide (not shown) of the sheet S is mounted as a packing material. .

  In this embodiment, the holding member 23 is basically composed of a corrugated cardboard 31 that is a packing member that is inexpensive and also has cushioning properties so as not to damage parts. In this embodiment, the corrugated cardboard 31 constituting the holding member 23 has a volatile organic compound adsorptivity.

  The corrugated cardboard 31 constituting the holding member 23 is formed with an adsorbing layer 32 on the surface in the same manner as the adsorbent-packed member 30A shown in FIG. 3 or the adsorbent-containing packing member 30B shown in FIG. Or contains the adsorbent 33. The adsorbing layer 32 is preferably provided on both sides of the cardboard 31, but it should be provided only on the side facing the outside when assembled as at least the holding member 23. Of course, like the first embodiment, the cardboard 31 may be provided with adsorptivity of volatile organic compounds by other methods.

  Thus, by providing the holding member 23 with the adsorptivity of the volatile organic compound, the outer layer generated in the image forming apparatus 1 when left in a high temperature environment for a long period of time, for example, in a substantially sealed state as in distribution. It can actively adsorb and deodorize volatile organic compounds from electric substrates, various rollers, etc.

  Here, a holding member 23 that is mounted on the insertion portion of the process cartridge 7 in the image forming apparatus main body A to be packed and holds and fixes the transfer roller 8 and the conveyance guide (not shown) of the sheet S is shown in FIG. As described above, by using the holding member 23 having substantially the same shape as the process cartridge 7, the holding member 23 having the adsorptivity of the volatile organic compound is provided almost throughout the insertion portion of the process cartridge 7 in the image forming apparatus main body A. Therefore, the adsorptivity can be further improved.

  Further, the holding member for fixing the components inside the apparatus is not limited to the one attached to the insertion portion of the process cartridge 7. For example, in the paper feed cassette 2 that stores the sheets S, as shown in FIG. 8, a regulation plate that regulates the size of the sheets S is provided in the vertical direction 2a and the horizontal direction 2b, and for feeding the sheets S. An intermediate plate 2 c that raises the sheet S to the vicinity of the paper feed roller 3 is provided. The sheet S is not stored in the paper feed cassette 2 at the time of packing. Normally, the regulation plates 2a, 2b and the middle plate 2c are arbitrarily or automatically moved in accordance with the state of the sheet S, so that they can be detached or damaged due to dropping or vibration during distribution. There is sex. Therefore, as shown in FIG. 9, a holding member 24 that holds and fixes the restriction plates 2a and 2b and the intermediate plate 2c is mounted in the sheet feeding cassette 2 in the image forming apparatus main body A to be packed. Similarly to the holding member 23 attached to the insertion portion of the process cartridge 7 described above, the holding member 24 attached in the paper feed cassette 2 can be provided with adsorptivity of volatile organic compounds. Thus, in a substantially sealed state at the time of distribution, for example, when it is left in a high temperature environment for a long time, it actively adsorbs volatile organic compounds mainly generated in the sheet cassette 2 from the exterior or grease, It can be deodorized.

  In the present embodiment, the corrugated cardboard holding members 23 and 24 have been described as an example. However, for example, as described above, an adsorption layer containing an adsorbent or an adsorbent is provided to adsorb volatile organic compounds. For example, the holding members 23 and 24 may be made of a packing member made of other materials such as foamed polystyrene or pulp mold.

  When the same comparative test as in Example 1 was performed on the case where only the holding member 23 and / or 24 had the adsorptivity of the volatile organic compound, as in Example 1, when the conventional packing material was used The level of nasty smell was significantly reduced. By using it in combination with the decorative box 21 having the adsorptivity of volatile organic compounds and further the cushioning material 22 having the adsorptivity of volatile organic compounds, the level at which an unpleasant odor is felt at the time of unpacking is more effective. It was possible to reduce. In addition, the holding members 23 and 24 were created so that the adsorption layer 32 was exposed to the outside by the same packaging member 30A with the adsorption layer as that used in the comparative test of Example 1.

  As described above, according to the present embodiment, in addition to or instead of the configuration for providing the decorative box 21 and / or the buffer material 22 with the adsorptivity of the volatile organic compound, the holding member for fixing the components inside the apparatus. By providing adsorptive properties of volatile organic compounds to 23 and 24, the volatile organic compounds generated in the packing box (decorative box) are reduced, and the emission of volatile organic compounds during unpacking is effectively suppressed. For example, it is possible to prevent an unpleasant odor when unpacking. In particular, the adsorptivity of the volatile organic compound can be further enhanced by imparting the adsorptivity of the volatile organic compound to the holding members 23 and 24 in addition to the decorative box 21 and / or the buffer material 22.

  As mentioned above, although this invention was demonstrated according to the specific Example, this invention is not limited to the aspect of the said Example. For example, in each of the above embodiments, the case where the present invention is applied to the packaging material of the image forming apparatus as an industrial product has been described as an example. However, the present invention is not limited to this, and the entire product is covered (wrapped) with the packaging material. ), And can be applied to other industrial products (for example, home appliances and PCs) in the form of logistics for transporting products. As described above, the present invention is very effective for adsorbing volatile organic compounds generated in the physical distribution process not only for the image forming apparatus but also for other industrial products.
