Description

[Technical field]

[0001] The present invention relates to a packaging material and a package in which an article is packaged with the packaging material. [Background technology]

[0002] As a sheet-like packaging material, for example, one that includes a main body sheet that encases an item and a cutting tape that is attached to the main body sheet is known (see Patent Document 1). An item is wrapped in the packaging material to form a package. In such a package, the item can be removed from the package by cutting the main body sheet along the cutting tape.

[0003] However, the thickness of the packaging material is different between the portion with the cutting tape and the portion without the cutting tape. Therefore, when the packaging material is formed into a sheet, it is difficult to stack multiple sheets and to maintain the stacked state. Furthermore, when the packaging material is formed into a long shape in the longitudinal direction of the cutting tape, it is difficult to wind it in the longitudinal direction (form it into a roll) and to maintain the wound (formed into a roll) state.

[0014] Hereinafter, an embodiment of a packaging material and a package according to the present invention will be described with reference to Figs. 1 to 5. In the following drawings, the same or corresponding parts are given the same reference characters and their description will not be repeated. In the following description, the first direction is the direction along the x-axis of the coordinate system of each drawing, and the second direction intersecting the first direction is the direction along the y-axis of the coordinate system of each drawing.

[0015] First Embodiment The packaging material 100a according to the first embodiment is formed in a sheet shape as shown in FIG. 1. Specifically, the packaging material 100a is formed in a quadrangular shape (more preferably, a rectangular shape). The packaging material 100a includes a main body sheet 1 for wrapping an article, at least one first tape 2 attached to the main body sheet 1, and at least two second tapes 3, 3 attached to the main body sheet. In this embodiment, the packaging material 100a includes one first tape 2 and two second tapes 3, 3. The two second tapes are arranged such that the first direction is the longitudinal direction when the longitudinal direction of the first tape 2 is defined as a first direction. In this embodiment, the two second tapes 3, 3 are arranged such that the first direction is the longitudinal direction when the longitudinal direction of the first tape 2 is defined as a first direction. In this embodiment, the first tape 2 and the two second tapes 3, 3 are attached to one surface of the main body sheet 1 (specifically, the surface that is the inner side when packaging an article).

[0016] In this embodiment, the main body sheet 1 is formed in a sheet shape. Specifically, the main body sheet 1 is formed in a quadrangular shape (more specifically, a rectangular shape with the first direction being the long side). In this embodiment, the main body sheet 1 has two cut portions 1a, 1a formed by cutting the end portion. In this embodiment, the two cut portions 1a, 1a are formed so as to reach the edge of the main body sheet 1. In addition, the two cut portions 1a, 1a are formed at least at one end portion (in this embodiment, at both ends) of the main body sheet 1 in the first direction. In addition, the two cut portions 1a, 1a are formed with an interval in the second direction. As a result, a gripping portion 1b that can be gripped with fingers or the like is formed between the two cut portions 1a, 1a. In this embodiment, the main body sheet 1 has a gripping portion 1b at least at one end portion (specifically, at both ends) in the first direction. In this embodiment, the gripping portion 1b is formed in the center of the main body sheet 1 in the second direction.

[0017] The main body sheet 1 can be cut in a first direction. In this embodiment, the main body sheet 1 can be cut in the first direction starting from one end of the two cut portions 1a, 1a. Specifically, the main body sheet 1 can be cut in the first direction starting from one end of the two cut portions 1a, 1a by pinching the gripping portion 1b and pulling in the first direction.

[0018] In this embodiment, the main body sheet 1 is configured to be joined by overlapping both ends in the second direction. That is, the main body sheet 1 in this embodiment has two joining areas 1c, 1c that are joined in an overlapping state. Specifically, the main body sheet 1 has one of the two joining areas 1c, 1c at one end in the second direction. Also, the main body sheet 1 in this embodiment has the other of the two joining areas 1c, 1c at the other end in the second direction. In this embodiment, the two joining areas 1c, 1c are formed in a strip shape extending in the first direction. Also, in this embodiment, the two joining areas 1c, 1c are formed continuously over the entire length between both ends of the main body sheet 1 in the first direction. In this embodiment, at least one of the two joining areas 1c, 1c (in this embodiment, both) includes the edge of the main body sheet 1 in the second direction (specifically, the edge in the first direction and the edge in the second direction). Then, the two joining areas 1c, 1c are joined by overlapping each other to form a first joining portion 5 of the package 100c described later.

[0019] The size of the main sheet 1 is not particularly limited, and may be, for example, 100 cm 2 ~1000cm 2 The thickness of the main body sheet 1 is not particularly limited, and may be, for example, 10 μm to 100 μm, or 15 μm to 50 μm. The sheet material constituting the main body sheet 1 is not particularly limited, and may be, for example, a stretched film (directional film) or a non-stretched film. The material of the sheet material constituting the main body sheet 1 is not particularly limited, and may be, for example, polypropylene, polyethylene terephthalate, polyethylene, nylon, etc. The sheet material constituting the main body sheet 1 is not particularly limited, and may be, for example, a biaxially oriented polypropylene film, a uniaxially oriented polypropylene film, a non-stretched polypropylene film, a polyethylene terephthalate film, a polyethylene film, a nylon film, etc., and is preferably a biaxially oriented polypropylene film. These sheet materials may be used alone, or may be used by stacking a plurality of them (specifically, laminated).

[0020] The first tape 2 is arranged so that its length is in the first direction. In this embodiment, the first tape 2 is arranged over the entire length between both ends of the main body sheet 1 in the first direction. Also, in this embodiment, the first tape 2 is formed to a length equal to the length between both ends of the main body sheet 1 in the first direction. Also, in this embodiment, the first tape 2 is arranged so as to overlap with the center of the main body sheet 1 in the second direction. Also, in this embodiment, one end of the first tape 2 is arranged between two cut portions 1a, 1a formed at one end of the main body sheet 1 in the first direction. Also, in this embodiment, the other end of the first tape 2 is arranged between two cut portions 1a, 1a formed at the other end of the main body sheet 1 in the first direction.

[0021] Then, by bonding the first tape 2 to the main body sheet 1, the main body sheet 1 can be cut in a first direction along the first tape 2. In this embodiment, one end of the first tape 2 is positioned between the two cut portions 1a, 1a, so that one end of the first tape 2 overlaps with the gripping portion 1b. Therefore, by gripping the gripping portion 1b and pulling it in the first direction, the main body sheet 1 can be cut in the first direction along the first tape 2.

[0022] The width of the first tape 2 may be the same as the width of each second tape 3, or may be narrower than the width of each second tape 3. Specifically, the width of the first tape 2 is not particularly limited, and may be, for example, 0.05 to 1 times, 0.05 to 0.5 times, or 0.05 to 0.4 times the width of each second tape 3. In addition, the width of the first tape 2 is not particularly limited, and may be, for example, 2 mm to 5 mm.

[0023] The sheet material constituting the first tape 2 is not particularly limited, and for example, a stretched film (directional film) or a non-stretched film can be used. The material of the sheet material constituting the first tape 2 is not particularly limited, and for example, polypropylene, polyethylene terephthalate, polyethylene, nylon, etc. can be used. The sheet material constituting the first tape 2 is not particularly limited, and for example, biaxially oriented polypropylene film, uniaxially oriented polypropylene film, non-oriented polypropylene film, polyethylene terephthalate film, polyethylene film, nylon film, etc. can be used, and preferably, biaxially oriented polypropylene film. These sheet materials may be used alone, or a plurality of them may be stacked (specifically, laminated). These sheet materials may be coated with an adhesive or a coating agent.

[0024] The method for bonding the first tape 2 to the main body sheet 1 is not particularly limited, and may be, for example, by using the self-adhesive function of the first tape 2, by heat sealing by melting the first tape 2, or by heat sealing with a part coating agent applied. The first tape 2 may be bonded entirely to the main body sheet 1, or only partially (for example, only both ends in the width direction) to the main body sheet 1.

[0025] In this embodiment, the two second tapes 3,3 are arranged so that the first direction is the longitudinal direction. In this embodiment, the two second tapes 3,3 are arranged over the entire length between both ends of the main body sheet 1 in the first direction. In addition, in this embodiment, the two second tapes 3,3 are formed to have a length equal to the length between both ends of the main body sheet 1 in the first direction. In addition, the two second tapes 3,3 are arranged at intervals in the second direction. In addition, at least one first tape 2 is arranged between the two second tapes 3,3 in the second direction. That is, in this embodiment, one of the two second tapes 3,3 (hereinafter also referred to as "one second tape 3") is arranged on one side of the first tape 2 in the second direction. In addition, the other of the two second tapes 3,3 (hereinafter also referred to as "the other second tape 3") is arranged on the other side of the first tape 2 in the second direction. In addition, in this embodiment, the two second tapes 3,3 are arranged at intervals from the first tape 2 in the second direction.

[0026] In this embodiment, one second tape 3 is positioned closer to one end of the main body sheet 1 in the second direction than the intermediate portion between one end of the main body sheet 1 and the first tape 2 in the second direction. Also, in this embodiment, the other second tape 3 is positioned closer to the other end of the main body sheet 1 in the second direction than the intermediate portion between the other end of the main body sheet 1 and the first tape 2 in the second direction. Also, in this embodiment, the two second tapes 3,3 are positioned closer to the center of the main body sheet 1 in the second direction than both end portions (two bonding regions) 1c,1c of the main body sheet 1 in the second direction. Also, in this embodiment, the two second tapes 3,3 are positioned at an interval in the second direction from the two bonding regions 1c,1c.

[0027] In this embodiment, the two second tapes 3, 3 are disposed at a distance in the second direction from the two cut portions 1a, 1a of the main body sheet 1. Moreover, in this embodiment, one of the two cut portions 1a, 1a is located between one second tape 3 and the first tape 2 in the second direction. Moreover, in this embodiment, the other of the two cut portions 1a, 1a is located between the other second tape 3 and the first tape 2 in the second direction.

[0028] The width of each second tape 3 may be the same as the width of the first tape 2, or may be wider than the width of the first tape 2. Specifically, the width of each second tape 3 is not particularly limited, and may be, for example, 1 to 20 times, 1 to 10 times, or 1 to 5 times the width of the first tape 2. The specific width of each second tape 3 is not particularly limited, and may be, for example, 5 mm to 40 mm, or 10 mm to 40 mm. The thickness of each second tape 3 is not particularly limited, and may be, for example, the same as the thickness of the first tape 2, or may be thicker than the thickness of the first tape 2. The thickness being the same means that the ratio of the thickness of the second tape 3 to the thickness of the first tape 2 is 0.9 to 1.1.

[0029] The sheet material constituting each second tape 3 is not particularly limited, and for example, a stretched film (directional film) or a non-stretched film can be used. In addition, examples of the material of the sheet material constituting each second tape 3 include polypropylene, polyethylene terephthalate, polyethylene, and nylon. Specifically, the sheet material constituting each second tape 3 is not particularly limited, and for example, biaxially oriented polypropylene film, uniaxially oriented polypropylene film, non-oriented polypropylene film, polyethylene terephthalate film, polyethylene film, and nylon film can be used, and preferably, biaxially oriented polypropylene film. These sheet materials may be used alone, or a plurality of them may be stacked (specifically, laminated). In addition, these sheet materials may be coated with an adhesive or a coating agent.

[0030] The method of bonding each second tape 3 to the main body sheet 1 is not particularly limited, and may be, for example, a method using the self-adhesive function of each second tape 3, a heat seal by melting each second tape 3, or a heat seal with a part coating agent applied. Also, each second tape 3 may be bonded to the main body sheet 1 in its entirety, or only a part of it (for example, only both ends or only the center in the width direction) may be bonded to the main body sheet 1.

[0031] Second Embodiment The packaging material 100b according to the second embodiment differs from the first embodiment in that it is formed in an elongated shape with the first direction as the longitudinal direction, as shown in Fig. 2. Therefore, the differences from the first embodiment will be described below.

[0032] In the packaging material 100b of this embodiment, the main body sheet 1 of the first embodiment is formed in an elongated shape so that its length is in the first direction. In addition, in the packaging material 100b of this embodiment, the first tape 2 of the first embodiment is formed in an elongated shape so that its length is in the first direction. In addition, in the packaging material 100b of this embodiment, the first tape 2 of the first embodiment is formed in an elongated shape so that its length is in the first direction. In addition, in this embodiment, the packaging material 100b can be wound in the first direction to be formed into a roll.

[0033] The packaging material 100b of this embodiment can be cut in the second direction (specifically, the width direction) to form the sheet-shaped packaging material 100a of the first embodiment. Specifically, the packaging material 100b can be cut in the second direction (specifically, the width direction) and a pair of cut portions 1a, 1a can be formed to form the packaging material 100a of the first embodiment. In addition, the packaging material 100b of this embodiment can be formed into a package 100c, as described below.

[0034] <Package> By packaging an article with the packaging material 100a of the first embodiment or the packaging material 100b of the second embodiment, a package 100c can be formed as shown in Figures 3 to 5. In the package 100c, two sheet-like facing portions 4, 4 arranged to face each other are formed with the packaging material 100a (or packaging material 100b). Then, a storage space R for storing an article X is formed between the two sheet-like facing portions 4, 4.

[0035] Moreover, the package 100c (specifically, one of the two sheet-like facing parts 4, 4) has a first bonding part 5 formed by bonding two bonding areas 1c, 1c in the main body sheet 1 together. In this embodiment, the first bonding part 5 is formed in one of the two sheet-like facing parts 4, 4 (hereinafter also referred to as "one sheet-like facing part 4"), and is not formed in the other of the two sheet-like facing parts 4, 4 (hereinafter also referred to as "the other sheet-like facing part 4"). The first bonding part 5 is formed in a strip shape extending in the first direction. Moreover, the first bonding part 5 is formed over the entire length between both ends of the package 100c in the first direction. In this embodiment, the first bonding part 5 is formed by bonding one surface of the main body sheet 1 in the two bonding areas 1c, 1c facing each other. The method of forming the first bonding part 5 is not particularly limited, and examples thereof include a method of overlapping two bonding areas 1c, 1c and heat sealing them.

[0036] The package 100c also includes two second joints 6, 6 formed by joining the two sheet-like opposing parts 4, 4 together so as to close the storage space R at positions spaced apart in the first direction. In this embodiment, the two second joints 6, 6 are formed in a strip shape extending in the second direction. The two second joints 6, 6 are also formed over the entire length between both ends of the package 100c in the second direction. In this embodiment, the two second joints 6, 6 are also formed at intervals from both ends of the package 100c in the first direction. The method of forming the two second joints 6, 6 is not particularly limited, and examples thereof include a method of heat-sealing the two sheet-like opposing parts 4, 4 together.

[0037] In this embodiment, the packaging body 100c has a non-joined portion 7 where the two sheet-like opposing portions 4,4 are not joined to each other at least at one end (specifically, at each of both ends) in the first direction. The two non-joined portions 7,7 are formed in a band shape extending in the second direction. In this embodiment, the two non-joined portions 7,7 are formed over the entire length between both ends of the packaging body 100c in the second direction.

[0038] The packaging body 100c (specifically, the other sheet-like opposing portion 4) of this embodiment has two cut portions 1a, 1a (specifically, gripping portion 1b) at least at one end (specifically, each of both ends) in the first direction. In this embodiment, the packaging body 100c has two cut portions 1a, 1a (specifically, gripping portion 1b) at least at one (specifically, both) of the two non-jointed portions 7, 7. In this embodiment, in a plan view of the packaging body 100c seen along the direction in which the two sheet-like opposing portions 4, 4 face each other, one gripping portion 1b is arranged so as to overlap one end of the first joint portion 5. In this embodiment, in a plan view, the other gripping portion 1b is arranged so as to overlap the other end of the first joint portion 5.

[0039] In addition, in the packaging body 100c, all the second tapes 3 are located on one of the sheet-like facing parts 4. That is, one of the sheet-like facing parts 4 includes all of the second tapes 3, and does not include the first tape 2. In this embodiment, one of the sheet-like facing parts 4 includes two second tapes 3,3 spaced apart in the second direction. And, a first joint part 5 is disposed between the two second tapes 3,3 in the second direction. The two second tapes 3,3 are disposed apart from the first joint part 5. The two second tapes 3,3 are disposed over the entire length of the storage space R in the first direction (over the entire length of the packaging body 100c in the first direction in this embodiment). Also, the two second tapes 3,3 are disposed apart from both ends of the packaging body 100c in the second direction (specifically, both ends of the two sheet-like facing parts 4,4 in the second direction) in a plan view.

[0040] In addition, in this embodiment, in the packaging body 100c, the first tape 2 is arranged on the side of the other sheet-like facing portion 4. That is, in the packaging body 100c, the other sheet-like facing portion 4 includes the first tape 2, but does not include the two second tapes 3,3. In addition, in this embodiment, the first tape 2 is arranged in the packaging body 100c in the second direction (specifically, in the center between both ends of the other sheet-like facing portion 4). In addition, in a plan view, the first tape 2 is arranged between the two second tapes 3,3 in the second direction. In addition, in a plan view, the first tape 2 is arranged with a gap between the two second tapes 3,3. In addition, in this embodiment, the first tape 2 is arranged over the entire length of the storage space R in the first direction (specifically, over the entire area of ​​the packaging body 100c in the first direction).

[0041] When removing the article X from the packaging body 100c, for example, the tab 1b formed at one end of the packaging body 100c in the first direction is pulled toward the other end of the packaging body 100c in the first direction. This causes the main body sheet 1 to be cut along the first tape 2, so that the article X can be removed from the storage space R.

[0042] The method for forming the packaging body 100c is not particularly limited. For example, a method including a step of cutting the packaging material 100b according to the second embodiment in the width direction to form the packaging material 100a according to the first embodiment, a step of overlapping two joining regions 1c, 1c of the packaging material 100a with each other so as to form the storage space R with one surface of the packaging material 100a (one surface of the main body sheet 1) facing inward to form the first joining portion 5, and a step of forming two second joining portions 6, 6 so as to close the storage space R can be mentioned. Alternatively, another method of forming the packaging body 100c includes a method (so-called pillow packaging) comprising the steps of forming a first joint 5 by overlapping two joint areas 1c, 1c of the packaging material 100b of the second embodiment while forming a storage space R with one side of the packaging material 100b (one side of the main sheet 1) facing inward, forming two second joints 6, 6 so as to close the storage space R, and cutting the packaging material 100b in the width direction with the first joint 5 and the two second joints 6, 6 formed to obtain the packaging body 100c.

[0043] As described above, the packaging materials 100a, 100b according to this embodiment can be stably stacked or rolled, and can stably maintain the stacked or rolled state.

[0044] That is, by disposing the first tape 2 between the two second tapes 3, 3 in the second direction and disposing the first tape 2 at a distance from the two second tapes 3, 3, the difference in thickness between the portion of the packaging material 100a, 100b including each second tape 3 and the portion including the first tape 2 is relatively small. This allows the packaging materials 100a, 100b to be stably overlapped or rolled, and the overlapped or rolled state to be stably maintained.

[0045] Moreover, one of the second tapes 3 is disposed closer to one end of the main body sheet 1 in the second direction than an intermediate portion between one end of the main body sheet 1 in the second direction and the first tape 2. Moreover, the other of the second tapes 3 is disposed closer to the other end of the main body sheet 1 in the second direction than an intermediate portion between the other end of the main body sheet 1 in the second direction and the first tape 2. Moreover, the first tape 2 is disposed so as to overlap with the center portion of the main body sheet 1 in the second direction. This allows the packaging materials 100a, 100b to be stacked or rolled more stably, and the stacked or rolled state can be maintained more stably.

[0046] Furthermore, by positioning the two second tapes 3,3 closer to the center of the main body sheet 1 in the second direction than both end portions of the main body sheet 1 in the second direction, it is possible to prevent the joining from being hindered by each second tape 3 when joining both end portions of the main body sheet 1 in the second direction.

[0047] Moreover, one end of the first tape 2 is located between the two cut portions 1a, 1a. Moreover, in the second direction, one cut portion 1a is located between one second tape 3 and the first tape 2. Moreover, the other cut portion 1a is located between the other second tape 3 and the first tape 2. This makes it possible to prevent the second tapes 3 from interfering with the cutting of the main body sheet 1 when the main body sheet 1 is cut.

[0048] In addition, in the packaging body 100c, one sheet-like facing portion 4 has two second tapes 3,3, so that the rigidity of one sheet-like facing portion 4 is higher than that of the other sheet-like facing portion 4. This allows the shape of the packaging body 100c to be maintained well. In addition, the other sheet-like facing portion 4 does not have two second tapes 3,3, so that when the packaging body 100c is viewed from the other sheet-like facing portion 4 side (front side), the two second tapes 3,3 can be prevented from affecting the design of the packaging body 100c. Furthermore, a step is formed between the main body sheet 1 and the two second tapes 3,3 on the storage space R side, so that such a step can prevent the movement of the article in the storage space R. In addition, since one sheet-like facing portion 4 has two second tapes 3,3, it is easy to fold back the main body sheet 1 near the two second tapes 3,3, so that one sheet-like facing portion 4 can be easily formed.

[0049] In addition, in the packaging body 100c, the first joint 5 is positioned between the two second tapes 3, 3 in the second direction, so that the rigidity of one sheet-like opposing portion 4 is higher than that of the other sheet-like opposing portion 4, and therefore the shape of the packaging body 100c can be well maintained.

[0050] The packaging material and package according to the present invention are not limited to the above-mentioned embodiment, and various modifications are possible within the scope of the present invention. In addition, the configurations and methods of the above-mentioned embodiments may be arbitrarily adopted and combined (the configurations and methods of one embodiment may be applied to the configurations and methods of other embodiments), and the configurations and methods of the various modified examples described below may be arbitrarily selected and adopted in the configurations and methods of the above-mentioned embodiments. Furthermore, the effects of the packaging material and package according to the present invention are not limited to the effects described in the above-mentioned embodiment.

Also, at least one of the two cut portions 1a, 1a may be configured not to reach the edge.

[0055] In addition, in the above embodiment, two cut portions 1a, 1a (i.e., gripping portion 1b) are formed at each of both end portions of the main body sheet 1 in the first direction, but this is not limited to this, and for example, two cut portions 1a, 1a (i.e., gripping portion 1b) may be formed only at one end portion of the main body sheet 1 in the first direction.

[0056] In addition, in the above embodiment, both ends of the first tape 2 are positioned between the two cut portions 1a, 1a, but this is not limited to this, and for example, at least one of the both ends of the first tape 2 does not have to be positioned between the two cut portions 1a, 1a.

[0057] In addition, in each of the above embodiments, the first tape 2 is positioned so as to overlap with the central portion of the main body sheet 1 or the packaging body 100c in the second direction, but this is not limited to this and, for example, the first tape 2 may be positioned on one end side or the other end side of the central portion of the main body sheet 1 or the packaging body 100c in the second direction.

[0058] In addition, in the above embodiment, the gripping portion 1b is positioned in the center of the packaging material 100a or the packaging body 100c in the second direction, but this is not limited to this and, for example, it may be positioned on one end side or the other end side of the center of the packaging material 100a or the packaging body 100c in the second direction.

[0059] Also, in the above embodiment, each bonding area 1c is configured to include an edge of the main body sheet 1, but is not limited to this and may be formed, for example, at a distance from an edge of the main body sheet 1 (for example, at least one of an edge in the first direction and an edge in the second direction).

[0060] In the first embodiment, the first tape 2 and each second tape 3 are arranged over the entire length between both ends of the main body sheet 1 in the first direction, but this is not limited to this, and for example, at least one of the first tape 2 and each second tape 3 may be arranged at a position away from both ends of the main body sheet 1 in the first direction. In other words, at least one of the first tape 2 and each second tape 3 may be configured to be shorter than the length between both ends of the main body sheet 1 in the first direction.

[0061] In addition, in each of the above embodiments, the two second tapes 3, 3 are arranged at a distance from the two bonding regions 1c, 1c, but this is not limited thereto, and for example, one second tape 3 may be arranged adjacent to one bonding region 1c, and the other second tape 3 may be arranged adjacent to the other bonding region 1c. In such a case, in the package 100c, the two second tapes 3, 3 are arranged adjacent to the first bonding portion 5.

[0062] In addition, in the second embodiment, the first tape 2 and each second tape 3 are arranged continuously in the longitudinal direction of the main body sheet 1, but this is not limited to this, and for example, at least one of the first tape 2 and each second tape 3 may be arranged intermittently in the longitudinal direction of the main body sheet 1.

[0063] In addition, in the above embodiment, the two second tapes 3,3 are arranged outside the midpoint between both ends of the main body sheet 1 and the first tape 2 in the second direction, but this is not limited to this, and for example, the two second tapes 3,3 may be arranged closer to the first tape 2 than the midpoint between both ends of the main body sheet 1 and the first tape 2 in the second direction.

[0064] In addition, in the first embodiment, each second tape 3 is arranged continuously over the entire length between both ends of the main body sheet 1 in the first direction, but this is not limited to this, and for example, multiple second tapes 3 may be arranged at intervals in the first direction.

[0065] In the above embodiment, the non-jointed portion 7 and the gripping portion 1b are formed at both ends of the packaging body 100c in the first direction, but this is not limited thereto, and for example, the non-jointed portion 7 and the gripping portion 1b may be formed at only one of the ends of the packaging body 100c in the first direction. Also, the packaging body 100c may be configured so that the non-jointed portion 7 is not formed at both ends in the first direction.

[0066] In addition, in the packaging body 100c of the above embodiment, one gripping portion 1b is arranged to overlap one end of the first joint 5 in a plan view, but this is not limited thereto, and for example, one gripping portion 1b may be configured not to overlap one end of the first joint 5. In addition, in the above embodiment, the other gripping portion 1b is arranged to overlap the other end of the first joint 5 in a plan view, but this is not limited thereto, and for example, the other gripping portion 1b may be configured not to overlap the other end of the first joint 5.

[0067] Furthermore, in the packaging body 100c of the above embodiment, the first joint 5 is formed by one side of the packaging materials 100a, 100b facing each other in the two joining regions 1c, 1c, but is not limited to this and may be formed, for example, by one side and the other side of the packaging materials 100a, 100b facing each other and joining them in the two joining regions 1c, 1c.

[0068] In addition, the packaging material 100a of the first embodiment may be formed by cutting the packaging material 100b of the second embodiment in the width direction, or may be formed by bonding a first tape 2 and two second tapes 3, 3 to a sheet-like main body sheet 1.

[0069] In the above embodiment, the packaging body 100c having the two sheet-like opposing portions 4, 4 is formed by the packaging materials 100a, 100b, but the present invention is not limited to this. For example, as shown in FIG. 6, the packaging body 100d may be formed by deforming the packaging material 100a along the article to wrap the article. The packaging material 100a forming the packaging body 100d may be configured not to have two joining regions 1c, 1c. The packaging material 100a forming the packaging body 100d may be configured to have a cut portion 10a (specifically, a U-shaped cut portion 10a) formed by cutting an area (for example, a central portion) inside the outer peripheral end portion of the main body sheet 1. In such a case, the packaging material 100a may have a covering sheet 8 that covers the cut portion 10a. The covering sheet 8 has a covering region 8a that is bonded to the main body sheet 1 while covering the cut portion 10a, and a covering sheet gripping portion 8b that can be gripped with fingers or the like. The covering region 8a is attached to the inside portion of the cut portion 10a in the main body sheet 1. At least the area around the cut portion 10a of the covering region 8a is peelably attached to the main body sheet 1. As a result, by pinching and pulling the covering sheet pinching portion 8b, the inside portion of the cut portion 10a in the main body sheet 1 is pulled together with the covering sheet 8, so that the main body sheet 1 can be cut starting from the end of the cut portion 10a.

[0070] In addition, in the packaging body 100c of the above embodiment, as shown in Figure 7, a portion of the packaging material 100a, 100b may be folded between the two sheet-like opposing portions 4, 4 to form at least one gusset portion 9 (specifically, two gusset portions 9, 9).
