The fixing member 5 is not particularly limited as long as it has a winding force. For example, as shown in FIG. 3, a tightening band 50 as a winding member having a band portion 51 and a buckle 52 may be used, or the band portion 51 may be welded and fixed. The material and width or thickness of the band portion 51 and the material or type of the buckle 52 are not particularly limited and may be appropriately selected according to the size and weight of the laminated body 2. Examples of the band portion 51 include a resin material such as a PP band and a cloth material.

The to-be-packaged object 1 is manufactured as follows using the above-mentioned laminated body 2, contact suppressing member 3, protective plate 4, and fixing member 5.
The following operations may be performed by the apparatus as a whole, manually by an operator, or may be partially performed by the apparatus or an operator. Also, a plurality of operations may be performed at the same time.

First, the contact suppressing member 3 is placed on the protective plate 4. The contact suppressing member 3 is preferably placed such that the center thereof overlaps the center of the protective plate 4 and the entire outer edge thereof is located inside the outer edge of the protective plate 4.
In addition, a plurality of laminated bodies 2 and contact suppressing members 3 are placed on the contact suppressing member 3 in this order. At this time, the laminated body 2 is placed so that the entire outer edge of the laminated body 2 is located inside the outer edge of the protective plate 4. In addition, it is preferable that the laminated body 2 and the contact suppressing member 3 are placed so that the centers thereof overlap with the center of the protective plate 4. Further, the number and weight of the stacked body 2 are not particularly limited, but the inertial force when the object to be packed 1 is conveyed in the plane direction of the plate-shaped substrate 21 and stopped, and when the object to be packed 1 is placed vertically. Due to gravity (when placed so that the plane direction of the plate-shaped substrate 21 is parallel to the vertical direction), the laminated body 2 is not displaced with respect to the protective plate 4, or the second protective film is displaced even if displaced. It is preferable to set such that the entire outer edge of 23 is not located outside the outer edge of the protection plate 4.

Further, the protection plate 4 is placed on the uppermost contact suppressing member 3. At this time, the protection plate 4 is arranged so that the direction along the ridgeline 41A of the center 41 of the upper protection plate 4 (hereinafter referred to as the ridgeline direction) is parallel to the ridgeline direction of the lower protection plate 4. Place on top. In addition, it is preferable that the protective plate 4 is placed so as to overlap with the protective plate 4 located below the laminated body 2 in a plan view.

Next, the first and second rubber bands 5A and 5B are wound around the laminated body 2, the contact suppressing member 3, and the protective plate 4. At this time, as shown in FIG. 2, the first rubber band 5A is hung so that the angle θ1 between the longitudinal direction and the ridgeline direction of the first rubber band 5A indicated by the two-dot chain line is 0° or more and 30° or less. turn. In the present embodiment, as shown by the solid line in FIG. 2, the first rubber band 5A is attached to the protective plate 4 so that the longitudinal direction is parallel to the short side direction of the protective plate 4, that is, θ1 is 0°. It hangs around the center of the long side of. Further, the second rubber band 5B is wound around so that the angle θ2 formed by the longitudinal direction of the first rubber band 5A and the longitudinal direction of the second rubber band 5B is 50° or more and 90° or less. In this embodiment, the second rubber band 5B is wound around the center of the short side of the protective plate 4 so that the longitudinal direction is parallel to the long side direction of the protective plate 4, that is, θ2 is 90°. ..
The total tension of the first and second rubber bands 5A and 5B wound around as described above is preferably 10 N or more and 80 N or less.
When it is less than 10 N, the fixing force is insufficient and the laminate 2 is displaced. If it exceeds 80 N, the protection plate 4 may be bent or the protection plate 4 and the first and second rubber bands 5A and 5B may come into strong contact with each other, and the protection plate 4 may be damaged. The total tension of the first and second rubber bands 5A and 5B is more preferably 15 N or more, and further preferably 20 N or more. The total tension of the first and second rubber bands 5A and 5B is preferably 60 N or less, more preferably 50 N or less.

Therefore, as shown in FIG. 4, even if the second rubber band 5B is wound around so that the angle formed by the longitudinal direction thereof and the ridge line 41A is 90°, the protective plate 4 is protected by the geometric rigidity effect. It is possible to suppress the portion of the plate located outside the plate-shaped substrate 21 from being largely bent along the ridge line 41A.
With the above work, the manufacture of the packaged object 1 is completed.

As shown in FIG. 3, when using the tightening band 50, first, the band portions 51 of the two tightening bands 50 are isolated from each other on a work table for a predetermined time, and placed in parallel with each other, and then protected. Place the plate 4. At this time, similarly to the first rubber band 5A, the belt is placed so that the angle between the ridge direction and the longitudinal direction of the band portion 51 is 0° or more and 30° or less.
Then, similarly to the case where the first and second rubber bands 5A and 5B are used, the laminated body 2, the contact suppressing member 3, and the protective plate 4 are placed, and the band portion 51 is attached to the laminated body 2, the contact suppressing member 3, and the protective member. It is hung around the plate 4, and its both ends are fixed with the buckles 52. Then, the band portion 51 is tightened by pulling the end portion 51A of the band portion 51 on the side where the buckle 52 is not provided from the position shown by the chain double-dashed line in FIG. 3 to the position shown by the solid line. The total tension of the band portion 51 is preferably 10 N or more and 80 N or less.

At this time, the first side portion 4A of the protection plate 4 which is not in contact with the band portion 51 does not deform as shown in FIG. Further, since the first side portion 4A is not deformed, the contact suppressing member 3 and the portion of the second protective film 23 on the side of the first side portion 4A are hardly deformed.
On the other hand, as shown in FIG. 7, the protective plate 4 in contact with the band portion 51 is slightly bent along the line parallel to the ridgeline 41A of the center core 41 by the winding force of the band portion 51. Due to the bending of the second side portion 4B, the portions of the contact suppressing member 3 and the second protective film 23 on the side of the second side portion 4B slightly bend along the outer edge of the plate-shaped substrate 21.

The entire outer edge of the laminate is located outside the outer edge of the laminate 2.
Therefore, when the packaged object 1 is accommodated in the bag body 11, the bag body 11 is arranged so as to bridge the outer edges of the pair of protective plates 4, and the bag body 11 and the first and first A gap can be formed between the outer edges of the second protective films 22 and 23. Therefore, the rubbing between the bag body 11 and the first and second protective films 22 and 23 can be suppressed, and the particles due to the rubbing can be prevented from adhering to the plate-shaped substrate 21.

Since the protective plate 4 is fixed to the laminated body 2 by the fixing member 5, it is possible to suppress the displacement of the laminated body 2 with respect to the protective plate 4 when the packaged object 1 is transported.
In particular, since the first and second rubber bands 5A and 5B are used as the fixing member 5, both can be performed by a simple method of simply winding the first and second rubber bands 5A and 5B around the laminated body 2 and the protective plate 4. Can be fixed.

Since the ends of the second protective film 23, the contact suppressing member 3, and the protective plate 4 are bent along the outer edge of the plate-shaped substrate 21 by the winding force of the first and second rubber bands 5A and 5B, the bending causes the bending. It is possible to suppress the positional displacement of the laminated body 2 in the left-right direction in FIGS.
Further, when the tightening band 50 is used, the angle formed between the ridgeline direction of the core 41 of the protective plate 4 and the longitudinal direction of the band portion 51 is 0°, so that the second side portion 4B of the protective plate 4 is It is bent along a line orthogonal to the ridge line 41A. Therefore, as compared with the case where the first side portion 4A of the protection plate 4 is bent along the ridge line 41A, breakage of the protection plate 4 can be suppressed.

Since the corners of the protective plate 4 are formed to have obtuse angles in a plan view, it is possible to prevent the corners of the protective plate 4 from damaging or cutting the bag 11.

Since the contact suppressing member 3 is provided between the laminate 2 and the protective plate 4 or between the laminate 2, the laminate 2 protects the protective plate 4 and other laminates during transportation of the packaged object 1 or vertical placement. It is possible to suppress slipping with respect to the body 2. Therefore, particles generated by rubbing between the bag body 11 and the first and second protective films 22 and 23 may adhere to the plate-shaped substrate 21 or the plate-shaped substrate 21 may collide with the floor or be damaged. Can be suppressed.

Since at least a part of the end region of the first protective film 22 is not in contact with the end region of the second protective film 23, the tab 22C and the outer edge of the plate-shaped substrate 21 in the second protective film 23 are more Also, the first and second protective films 22 and 23 can be easily peeled off by gripping the portion located on the outer side. Even with the laminated body 2 having such an effect, the rubbing between the bag body 11 and the first and second protective films 22 and 23 can be suppressed, and particles can be prevented from adhering to the plate-shaped substrate 21. it can.

[Modified example of packaged object]
For example, the laminated body may have a configuration in which the first protective film 22 or the second protective film 23 is arranged only on one surface of the plate-shaped substrate 21, or the first protective film 22 may be formed on both surfaces of the plate-shaped substrate 21. It may be a configuration in which only the film 22 or the second protective film 23 is arranged.
In the present modified example or the above-described embodiment, the number of stacked bodies forming the packaged object may be one.

The contact suppressing member 3 may be arranged only between the upper laminated body 2 and the protective plate 4 or between the lower laminated body 2 and the protective plate 4, or may not be arranged at all. Good.
Further, the contact suppression member 3 may be arranged between the plate-shaped bases 21 and 21 or between the first protective film 22 or the second protective film 23 and the plate-shaped base 21.

The corners of the protective plate 4 may be curved in plan view, or the entire shape of the protective plate 4 may not be octagonal as long as it is an obtuse angle. Even in this case, it is possible to prevent the corners of the protective plate 4 from damaging or cutting the bag body 11.
The corner portion of the protective plate 4 may be a right angle or an acute angle in plan view, and in this case, it is preferable that the housing member that comes into contact with the protective plate 4 has a structure that is not damaged or cut by the contact.
At least one of the pair of protective plates 4 may be made of a material that does not deform or may not have a corrugated board structure.
The protective plate 4 may be positioned so that the angle between the ridgeline direction and the longitudinal direction of the band portion 51 is 90°. In this case, when the protective plate 4 bends along the ridgeline direction. In addition, it is preferable to have a structure that does not break.
When the plate-shaped substrate 21 is bent, the protective plate 4 may have a bent shape along the shape of the laminate 2, as shown in FIG. 8. By doing so, the displacement of the plate-shaped substrate 21 can be suppressed more effectively. In addition, such a protection plate 4 can be produced by molding a foamed resin sheet, for example.
The end of the protective plate 4 may be bendable. As shown in FIG. 9, since the end portion of the protective plate 4 is bent, the contact between the plate-shaped base body 21 and the bag body 11 can be further suppressed. Further, in such a case, when the plate-shaped base 21 is placed, the end of the protective plate 4 may be bent after the plate-shaped base 21 is placed without bending the end of the protective plate 4. preferable. If the side surface of the laminate 2 is held when the plate-shaped substrate 21 is placed, it may cause the protective film 22 to be turned over or rubbed. Therefore, the main surface of the laminate 2 should be held by being sucked or pinched. Is preferred. In such a case, when the plate-shaped substrate 21 is placed, the stacked body 2 can be stacked in the lateral direction. Then, after the plate-shaped substrate 21 is placed, if the end portion of the protective plate 4 is bent for the purpose of protecting the side surface portion of the laminated body 2, adhesion of particles to the plate-shaped substrate 21 can be further suppressed.

The first rubber band 5A or the second rubber band 5B may not be wound around, or another rubber band may be wound next to the first rubber band 5A or the second rubber band 5B.
Although the tightening band 50 is composed of a tightening belt having the band portion 51 and the buckle 52, the tightening band is composed of a band-shaped or string-shaped winding member, and both end portions of the winding member are connected, adhered, or fused to each other. You may fix it, for example.
An adhesive tape may be applied as the fixing member.

[Modification of the package]
Although the packaged object 1 accommodated in the bag body 11 is accommodated in the box body 12, it does not have to be accommodated in the box body 12, and in this case, the weight and cost of the package body can be reduced.
The bag body 11 may be made of paper or cloth, and even in this case, the protection plate 4 can suppress the rubbing between the bag body 11 and the first and second protective films 22 and 23, which results from the rubbing. It is possible to prevent adhered particles from adhering to the plate-shaped substrate 21. Further, the bag body 11 may be configured by winding a sheet-shaped member made of resin, paper, or cloth around the packaged object 1.
The packaged object 1 may be directly housed in the box body 12 instead of being housed in the bag body 11. In this case, the box body 12 corresponds to the housing member of the present invention.

[Other modifications]

The application of the plate-shaped substrate of the present invention is not particularly limited. Specific examples include transparent parts for vehicles (headlight covers, side mirrors, front transparent substrates, side transparent substrates, rear transparent substrates, instrument panel surfaces, etc.), meters, building windows, show windows, building interior members, Building exterior materials, displays (notebook personal computers, monitors, LCDs, PDPs, ELDs, CRTs, PDAs, etc.), LCD color filters, touch panel substrates, pickup lenses, optical lenses, eyeglass lenses, camera components, video components, CCDs Cover substrate, optical fiber end face, projector component, copying machine component, transparent substrate for solar cell (cover glass, etc.), mobile phone window, backlight unit component (light guide plate, cold cathode tube, etc.), backlight unit component Improving LCD brightness Film (prism, semi-transmissive film, etc.), liquid crystal brightness enhancement film, organic EL light emitting device parts, inorganic EL light emitting device parts, phosphor light emitting device parts, optical filters, end faces of optical parts, illumination lamps, lighting fixture covers, amplification Examples thereof include laser light sources, antireflection films, polarizing films, agricultural films and the like.
The shape of the plate-shaped substrate is not particularly limited, and examples thereof include a circular plate, an elliptical plate, a triangular or pentagonal polygonal plate, and the like.

Examples of the plate-shaped substrate include general glass plates such as soda lime glass, borosilicate glass, aluminosilicate glass, and alkali-free glass, inorganic glasses made of inorganic materials of various compositions, or transparent resin plates. ..
Examples of the most suitable glass plate material include glass materials such as soda lime glass, quartz glass, quartz glass, and sapphire glass. Highly transparent glass having a lower iron content and less bluing is more preferable.
As the material of the transparent resin plate, a highly transparent resin material is preferable, for example, polycarbonate, polyester resin such as polyethylene terephthalate, polyolefin resin such as polypropylene, polyvinyl chloride, acrylic resin, polyether sulfone, poly Examples thereof include arylate, triacetyl cellulose, polymethyl methacrylate and the like.

As the plate-shaped substrate, a glass plate is most preferable in terms of high transparency, light resistance, heat resistance, low refractive index property, high flatness accuracy, surface scratch resistance, and high mechanical strength.
The mechanical strength may be increased in order to increase the safety of the glass plate. In order to increase the mechanical strength of the glass plate, the glass plate is previously subjected to a strengthening treatment.
As the strengthening treatment, physical strengthening by exposing the glass plate to high temperature and then air cooling, or immersing the glass plate in a molten salt containing an alkali metal, and an alkali having a small atomic diameter existing on the outermost surface of the glass plate Chemical strengthening may be mentioned in which a metal (ion) is replaced with an alkali metal (ion) having a large atomic system present in the molten salt.

Particularly when a thin glass plate is used, it is preferable to use a chemically strengthened glass plate (hereinafter also referred to as “chemically strengthened glass”).
The chemically strengthened glass as the plate-shaped substrate preferably satisfies the following conditions. That is, the surface compressive stress (hereinafter referred to as CS) of the glass substrate is preferably 400 MPa or more and 1200 MPa or less, and more preferably 700 MPa or more and 900 MPa or less. If CS is not less than the lower limit value, the strength is practically sufficient.
Further, if CS is equal to or less than the upper limit value, there is no concern that it will endure its own compressive stress and spontaneously break. When the plate-shaped substrate of the present invention is used as a front plate (cover glass) of a display device or the like, CS of the glass substrate is preferably 700 MPa or more and 850 MPa or less.

Further, the depth of stress value (hereinafter referred to as DOL) of the glass substrate is preferably 15 μm to 50 μm, more preferably 20 μm to 40 μm. If the DOL is at least the lower limit value, there is no concern that it will be easily scratched and destroyed.
Further, if the DOL is less than or equal to the upper limit value, there is no concern that the substrate will endure the compressive stress of the substrate itself and will be destroyed spontaneously. When the plate-shaped substrate of the present invention is used as a front plate (cover glass) of a display device or the like, the DOL of the glass substrate is preferably 25 μm or more and 35 μm or less.

From the viewpoint of mechanical strength, sapphire glass is also preferable.

The shape of the plate-shaped substrate is usually a smooth and rectangular shape. The shape of the plate-shaped substrate may be appropriately changed depending on the shape of the display panel of the display device, the design of the display device, the mounting position of the display device, and the like.
That is, the shape of the plate-shaped substrate is not limited to the smooth shape or the rectangular shape. For example, it may be template glass having irregularities on its surface, and may be polygonal, circular, or elliptical. Further, not only flat glass but also curved glass may be used.

The size of the plate-shaped substrate is appropriately determined depending on the size of the display panel and the use of the display device. For example, when used as a cover glass for a mobile device, it has a size of 30 mm×50 mm to 300 mm×400 mm, a thickness of 0.1 mm or more and 2.5 mm or less, and a display device, car navigation, console panel, instrument panel, etc. In the case of the device, it is preferably 50 mm×100 mm to 2000 mm×1500 mm, and the thickness is preferably 0.5 mm or more and 4 mm or less.

The thickness of the plate-shaped substrate is not particularly limited, and glass having a thickness of 10 mm or less can be used. In the case of a glass plate, it is usually about 0.1 mm to 6 mm in view of mechanical strength and transparency. In particular, when it is used in an on-vehicle display device, the plate-shaped substrate is required to have safety, and therefore it is preferably 0.2 mm or more and 2 mm or less from the viewpoint of mechanical strength.
When chemically strengthened glass is used, the thickness of the glass substrate is preferably 5 mm or less, and more preferably 3 mm or less, in order to effectively carry out the chemical strengthening treatment. In the case of a transparent resin plate, it is preferably 2 mm or more and 10 mm or less.
Since the light absorption can be suppressed to be low as the thickness is thin, it is preferable to use the glass plate from the viewpoint of improving visibility and improving transparency. The plate-shaped substrate is not necessarily limited to a single-layer structure composed of a single layer, and may have a multi-layer structure composed of a plurality of layers such as laminated glass.

<Protective film>
In order to protect the display panel assembled to the display device during the manufacturing process or the product transportation, the first protective film is attached to the plate-shaped substrate to protect the plate-shaped substrate.
When the display device is used, the first protective film is peeled off from the plate-shaped substrate and used.
Either surface of the protective film has an adhesive layer. Examples of the adhesive force include adhesive force, van der Waals force, and electrostatic force. From the viewpoint of easy peeling from the plate-shaped substrate and cost, the adhesive force is preferable, and the protective film preferably has an adhesive layer.
By adjusting the adhesive force of the pressure-sensitive adhesive forming the first pressure-sensitive adhesive layer, the pressure-sensitive adhesive is at least the outermost surface (first main surface or antireflection layer or antifouling layer or other functional layer) of the plate-shaped substrate. It is possible to suppress a part of the antireflection layer and the antifouling layer from peeling off.

Further, in order to enhance the peeling-off property of the protective film, the first protective film may be provided on the second protective film or the plate-shaped substrate by providing a portion where the adhesive layer is not formed on at least a part of the outer peripheral edge of the protective film. Can be easily peeled off. In addition, the tab portion manufactured for the purpose of facilitating the peeling property described above may protrude to the outer peripheral portion within a range not impairing the handling property.

When laminating the protective film with a plate-shaped substrate having an antireflection layer or an antifouling layer, it may be done manually, but the protective film supplied as a roll-shaped roll is laminated using a rubber roll or the like. From the viewpoint of production efficiency, it is preferable to cut the protective film in advance according to the dimensions of the plate-shaped substrate to form a sheet-shaped film and then bond the film with a labeling machine or a sticker machine.

<Film>
The film is not particularly limited as long as it is a resin film. Further, the film may have a single-layer structure, or may have a multi-layer structure in which a plurality of layers such as an antistatic layer, a hard coat layer and an easy-adhesion layer are laminated. Further, in order to prevent forgetting to remove the protective film from the plate-shaped substrate, a part or the whole surface of the film may be colored or a seal may be attached.

As the film, for example, a polyester film such as polyethylene terephthalate, a polyethylene film, a polyolefin film such as polypropylene, a polyvinyl chloride film, or the like can be used. Among these, a polyester film is preferable from the viewpoints of adhesion to the adhesive layer, durability and optical characteristics.

The thickness of the film is also not particularly limited. The thickness of the film is, for example, preferably 5 μm or more and 100 μm or less, and more preferably 15 μm or more and 75 μm or less because the film is easily bent and easily peeled when peeling. If it is less than 5 μm, the plate-shaped substrate may not be sufficiently protected, and if it exceeds 100 μm, the cost may increase.

<Adhesive layer>
The pressure-sensitive adhesive of the pressure-sensitive adhesive layer preferably has such a degree that the pressure-sensitive adhesive does not easily remain on at least a part of the outermost surface of the plate-shaped substrate when the protective film is peeled off from the plate-shaped substrate. The pressure-sensitive adhesive of the pressure-sensitive adhesive layer preferably has an adhesiveness that suppresses peeling of at least a part of the antireflection layer or the antifouling layer when the protective film is peeled from the plate-shaped substrate.
As such a pressure-sensitive adhesive, an acrylic-based or polyurethane-based pressure-sensitive adhesive or the like is preferably used from the viewpoint of adhesiveness and releasability.

When the adhesive strength of the adhesive layer is 0.01 N/10 mm or more, the adhesive can be uniformly attached to the outermost surface of the plate-shaped substrate, and the adhesive layer can be evenly attached to the antireflection layer and the antifouling layer. Further, there is no fear that the function as a film will be impaired, such as the film peeling off from the plate-like substrate during transportation.
When the adhesive force of the adhesive layer is 0.3 N/10 mm or less, the adhesive force of the adhesive layer is appropriate, and at the time of peeling the protective film, at least a part of the antireflection layer or the antifouling layer is peeled off more than necessary. In addition, there is no fear that the adhesive will remain on at least a part of the outermost surface of the plate-shaped substrate, resulting in deterioration of visibility and defects such as stains.

Examples of the present invention will be described. Examples 1 to 5 are examples and Example 6 is a comparative example. The present invention is not limited to the examples below.

[Fabrication]
[Example 1]
As a plate-shaped substrate, a glass for chemical strengthening having a thickness of 1.3 mm and a size in plan view of 120 mm×280 mm (unstrengthened Dragon Trail (registered trademark), manufactured by Asahi Glass Co., Ltd. (denoted as “DT” in Table 1) ) Prepared.
As the first protective film, a type A film (manufactured by Nitto Denko Corp., model number RP-207) including a film base made of PET having a size of 118 mm×278 mm in plan view and an adhesive layer was prepared.
As the second protective film, a type A having a size of the film substrate in plan view of 125 mm×285 mm was prepared. The static friction coefficient between the protective films is 0.08.

Miramat (registered trademark), which is a highly expanded polyethylene sheet, was prepared as a contact suppressing member. The static friction coefficient between the contact suppressing member and the protective film was 0.6.
As the protective plate, an octagonal plate-shaped type A (antistatic plastic corrugated cardboard) formed of plastic and similar to the above embodiment was prepared. The size of the protective plate in plan view is 170 mm×330 mm. The protective plate has a corrugated cardboard structure in which liners are provided on both sides of the core, and the total thickness is 3 mm. The flexural modulus is 35 N/cm.
As the fixing member, two rubber bands (rubber band count #180 manufactured by Kyowa Co., Ltd.) similar to those in the above-described embodiment were prepared.
A vinyl gusset bag (a gusset type PE bag manufactured by Plus Packaging System Co., Ltd.) was prepared as a housing member.

Then, first, the first and second protective films were attached to the first and second main surfaces of the plate-shaped substrate to prepare a laminate. At this time, the outer edge of the first film substrate of the first protective film is located 1 mm inside the outer edge of the plate-shaped substrate, and the second protective film is 2 mm deeper than the plate-shaped substrate over the entire outer peripheral direction thereof. A laminate was prepared so as to protrude to the outside by 0.5 mm so that the end regions of both protective films do not adhere to each other (there is no protection of the end face of the plate-shaped substrate). Further, a tab was attached to the first film so as to protrude to the outside by 1 mm from the plate-shaped substrate.
Next, after placing the contact suppressing member on the protective plate, 25 laminated bodies and 25 contact suppressing members were placed in this order. Further, a protective plate was placed on the top contact suppressing member. At this time, in plan view, the centers of the protective plate, the contact suppressing member, and the laminated body were made to overlap each other. In addition, the protective plate was arranged so as to protrude outside the plate-shaped substrate by 25 mm over the entire outer peripheral direction.

Then, using the first rubber band (Kyowa Co., Ltd., rubber band count #180), the protection plate is hung in the short side direction around the center of the long side, and the second rubber band (Kyowa Co., Ltd. rubber band). Band count #270) was wound around the center of the short side of the protective plate in the long side direction. At that time, the tension of the first rubber band was 12N and the tension of the second rubber band was 11N.
Then, the packaged body produced as described above was housed in a gusset bag to produce a package. At this time, in a side view, the gusset bag was configured to bridge the outer edges of the upper and lower protective plates in a substantially straight line shape.

[Example 2]
As the protective plate, type B type (Mitsui Chemicals Tohcello Co., Ltd. polypropylene triple foam sheet product name: Paronia (registered trademark)) is used, and the number of rubber bands (Kyowa Co., Ltd. rubber band count #180) is set to two. The two rubber bands were wound around the protective plate, the contact suppressing member and the laminated body so that the longitudinal direction thereof was parallel to the short side direction of the protective plate and separated by 50 mm. At that time, the tension of the rubber band was 12 N per one.
The material of the type B protective plate is a polypropylene (PP) triple foam sheet, the shape in plan view is a dodecagon, and the size is 170 mm×330 mm. The flexural modulus is 300 N/cm. The protective plate has a total thickness of 5 mm.
The packaged body produced in this manner was housed in a gusset bag under the same conditions as in Example 1 to produce a package.

[Example 3]
As the first protective film of the plate-shaped substrate, a type B film made of PE (model number RB-100S manufactured by Nitto Denko Corporation) was used, and the same material as type A was used as the protective plate, but with a thickness of 2 mm. The one of C was used. The flexural modulus is 12 N/cm. A fastening band having a polypropylene band portion was used as the fixing member. The coefficient of static friction between the protective film and the contact suppressing member was 0.3.
The size of the type B protective film in plan view is 154 mm×284 mm.
The shape of the type C protective plate in plan view is a rectangle having an R portion of 10 mm, and the size is 170 mm×330 mm.
Then, first, two tightening bands were arranged at a distance of 50 mm, and the same number of protective plates, contact suppressing members, and laminated bodies as those in Example 1 were placed thereon in the same manner as in Example 1. At this time, the center between the two tightening bands and the center of the laminated body were overlapped with each other, and the angle formed by the ridgeline direction of the center of the protective plate and the longitudinal direction of the band portion was 0°.
After that, both ends of the band part were fixed by buckles on the upper protection plate, and the ends of the band part on the side where the buckle was not provided were pulled to tighten the protection plate, the contact suppressing member, and the laminated body. At this time, the tension of each tightening band was set to 20 N so that the protective plate, the contact suppressing member, and the protective film were bent along the outer edge of the plate-shaped substrate.
The packaged body produced in this manner was housed in a gusset bag under the same conditions as in Example 1 to produce a package.

[Example 4]
As the plate-like substrate, DT having a size of 280 mm×140 mm in plan view and being uniformly concavely curved with a radius of curvature of 1000 mm in the short side direction was used. A type A protective film was used, and the size was 284 mm×144 mm in plan view. Other than that produced the to-be-packaged object on the same conditions as Example 1. Then, the packaged body was housed in a gusset bag under the same conditions as in Example 1 to produce a packaged body.

[Example 5]
An object to be packaged was produced under the same conditions as in Example 1 except that the fixing member was one rubber band (rubber band number #270 manufactured by Kyowa Co., Ltd.) and was wound around the center of the short side of the protective plate. The tension of the rubber band at that time was 7N. Then, the packaged body was housed in a gusset bag under the same conditions as in Example 1 to produce a packaged body.

[Example 6]
An object to be packed having only 26 contact suppressing members and 25 laminated bodies stacked in the same manner as in Example 1 was prepared without using the protective plate and the fixing member. Then, the packaged body was housed in the same gusset bag as in Example 1 to produce a packaged body.

[Evaluation]
[Particle evaluation]
The package of Example 1 was placed on a trolley, and the asphalt ground was moved for 20 minutes. Then, the objects to be packaged are taken out from the gusset bag, the green lamps are irradiated onto the end faces of the 25 plate-shaped bases, and the particles caused by the rubbing between the gusset bag and the protective film are attached to the end faces of the plate-shaped base. Whether or not it was visually confirmed. The same evaluation was performed for the packages of Examples 2 to 6.

As shown in Table 1, in the packaging bodies of Examples 1 to 5 in which the laminated body was arranged between the pair of protective plates, particles were not attached to the end faces of all the plate-shaped bases (evaluation A), but the pair of protective bodies was protected. In the packaging body of Example 6 which does not use a plate, there was a plate-shaped substrate with particles attached to the end surface (evaluation C).
The reason why the evaluation was A in Examples 1 to 5 is that since a pair of protective plates forms a gap between the gusset bag and the protective film, rubbing between the gusset bag and the protective film is suppressed, and particles are generated. Probably because he didn't. On the other hand, the reason why the evaluation was C in Example 6 is that since there is no pair of protective plates, the gusset bag and the protective film rub against each other to generate particles, and the generated particles pass between the pair of protective films. It is thought that this is because they reached the plate-shaped substrate.
From this, by sandwiching the laminate between the pair of protective plates, and by positioning the entire outer edge of the pair of protective plates outside the outer edge of the laminate, rubbing between the gusset bag and the protective film can be suppressed, and the rubbing can be performed. It was confirmed that particles can be prevented from adhering to the plate-shaped substrate due to the above.

[Vibration resistance evaluation]
The package of Example 1 was placed on a trolley to move the asphalt ground for 20 minutes, and then the package was taken out of the gusset bag, and the alignment of the plate-shaped substrates was confirmed. As shown in FIG. 10, the evaluation of the alignment condition is performed by comparing the outer edge of the plate-shaped base body 21 whose outer edge is located closest to the center of the protective plate 4 and the outer edge of the plate-shaped base body 21 located closest to the outer edge of the protective plate 4. The displacement amount A was evaluated, and the displacement amount A of 10 mm or more was evaluated as having no seismic resistance (evaluation C), and the displacement amount A of less than 10 mm was determined as seismic resistance (evaluation A).
The same evaluation was performed for Examples 2 to 6.

As shown in Table 1, in the packages of Examples 1 to 4 in which the total tension of the fixing members is 23N or more, the evaluation was A, but Example 5 and the fixing members in which the total tension of the fixing members was 7N or less were used. In Example 6, which was not evaluated, the evaluation was C.
From this, it was found that when the total tension of the fixing members was 20 N or more, the displacement of the substrate due to the vibration during transportation was further reduced.
Further, even in the same evaluation of A, the amount of deviation was particularly small between Example 1 and Example 3. It is speculated that Example 3 has a sufficiently high tension. In Example 1, it is presumed that it is difficult to move in all four directions because they are crossing and running around each other. It was found that Example 1 can suppress the particles and the displacement of the substrate most efficiently in consideration of the ease of winding.
