Description

  The present invention relates to a packaging body such as a packaging bag in which foods such as sandwiches and rice balls are packaged, and a label attached to the packaging body.

  In general, labels and campaigns with product information such as expiry date, raw material names, prices, barcodes, etc. are printed on packages such as sandwich bags and rice balls sold at convenience stores and supermarkets. Labels for use are affixed.

  For example, a sandwich with a triangular side is wrapped in a transparent film packaging bag so that it can be easily seen from the outside. A bread cut with ingredients is placed in front of the packaging bag, and a triangle is placed on both sides. It is packaged so that the side of the shape is located. In this packaging bag, a label printed with product information is attached to the back surface of the packaging bag so as not to block the line of sight from the front and side surfaces.

  On the back surface of the packaging bag, as described in Patent Document 1, for example, an opening end that is picked and manipulated to open the packaging bag is formed. The opening end is formed in the upper part of the back surface, and by opening and closing the opening end, an opening corresponding to the width of the opening end is formed on the back surface of the packaging bag from the top to the bottom. To be formed.

Japanese Patent Laid-Open No. 2008-1000071

  The label attached to the back of the packaging bag to be opened is wider than the width of the opening end, and is attached so as to cover the area where the opening is formed by operating the opening end to be lowered. Has been.

  For this reason, when opening by opening the opening edge and pulling it downward, if the opening position reaches the area where the label is attached, the label will interfere with the opening operation and prevent smooth opening. Will be.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a label that does not obstruct the opening of the package as much as possible, and a package using this label. .

In order to achieve the above object, the present invention is configured as follows.
(1) The label of the present invention is a label attached to a package that is opened along the dividing line so as to cover at least a part of the dividing line,
When assuming a virtual reference line that overlaps the dividing line in a state where the label is attached to the package, a non-adhesive region is formed in the vicinity of the virtual reference line on the adhesive surface of the label. Yes.

  A parting line is a line which becomes a boundary of a part separated from a package by opening the package.

  The vicinity of the virtual reference line includes both the vicinity including the virtual reference line and the vicinity not including the virtual reference line.

  According to the present invention, since the non-adhesive region is formed in the vicinity of the virtual reference line that overlaps the dividing line on the adhesive surface of the label, the vicinity of the virtual reference line of the label is separated from the package. Compared to the case where there is no non-adhesive area and the entire surface of the label is in close contact with the package, the operation force when opening is effectively applied in the vicinity of the virtual reference line that overlaps the dividing line. It becomes easy to open along the reference line.

(2) In a preferred embodiment of the present invention, the package includes a pair of the dividing lines on one side thereof, and the pair of dividing lines are formed so as to be along the opening direction at intervals. The label has a width wider than the interval between the pair of dividing lines, and when the pair of virtual reference lines respectively overlapping the pair of dividing lines is assumed on the label, the pair of virtual reference lines is The non-adhesive region is formed in the vicinity of each virtual reference line corresponding to each of the pair of virtual reference lines, with an interval in the width direction of the label and extending along a direction orthogonal to the width direction. According to this embodiment, since the non-adhesive regions are respectively formed in the vicinity of the pair of virtual reference lines that respectively overlap the pair of dividing lines of the package on the adhesive surface of the label, each label The neighborhood of the virtual reference line is Compared to the case where each is separated from the packaging body, there is no non-adhesive region, and the entire surface of the label is in close contact with the packaging body, the operating force at the time of opening is a pair of overlapping lines. It acts effectively in the vicinity of the virtual reference line and can be easily opened along a pair of virtual reference lines.

  (3) In one embodiment of the present invention, the non-bonded region is formed across the corresponding virtual reference line in the width direction.

  According to this embodiment, the non-adhesive region of the label is formed across the corresponding virtual reference line across the width direction of the label, i.e., the non-adhesive region of the label includes the virtual reference line and extends across both sides of the width direction. Since the adhesion region is formed, the operation force when opening the seal acts more effectively in the vicinity of the virtual reference line that overlaps the dividing line, and the opening becomes easy.

  (4) In another embodiment of the present invention, in the non-adhesive region, the distance from the corresponding virtual reference line to the non-adhesive region is within a first predetermined distance, and the first predetermined distance is the pair. The distance is 17% of the interval between the virtual reference lines.

  According to this embodiment, since the non-adhesion region in the vicinity of each virtual reference line is formed in the vicinity position within the first predetermined distance from the corresponding virtual reference line, the operation force at the time of opening is changed to a broken line. It can act effectively in the vicinity of the overlapping virtual reference line, and can be easily opened along the virtual reference line overlapping the dividing line.

  (5) In one embodiment of the present invention, a distance from each one end in the width direction of the label to a non-adhesion region on the adjacent side is equal to or greater than a second predetermined distance, and the second predetermined distance is equal to the pair. The distance is 10% of the interval between the virtual reference lines.

  According to this embodiment, the area from each end in the width direction of the label to the non-adhesion area on the adjacent side is an area that is not a non-adhesion area, that is, an adhesion area. Since it can ensure over a 2nd predetermined distance from one end, it can prevent that the both ends of the width direction of a label float up from a package.

  (6) In still another embodiment of the present invention, a knob is formed on the one surface of the package so as to be continuous with the upper ends of the pair of dividing lines. Cuts are respectively formed at positions corresponding to the virtual reference lines.

  According to this embodiment, by opening the handle so as to pick the knob and pull it downward, the portion between the pair of dividing lines connected to the knob is separated from the package and opened, and at the upper end of the label, The pair of dividing lines reach the cuts at positions corresponding to the pair of virtual reference lines, and can be opened more smoothly along the cuts.

  (7) In a preferred embodiment of the present invention, a pressure-sensitive adhesive layer is formed on the entire surface of the adhesive surface, and the non-adhesive region is formed on the pressure-sensitive adhesive layer to invalidate the pressure-sensitive adhesive force of the pressure-sensitive adhesive layer. It is an adhesive layer.

  According to this embodiment, the non-adhesive region can be formed in a required region by the pasting process.

  (8) In another embodiment of the present invention, the adhesive surface has an adhesive layer formed on the entire surface excluding the non-adhesive region.

  According to this embodiment, the required area can be set as a non-adhesive area by so-called pressure-sensitive adhesive pattern coating in which the pressure-sensitive adhesive layer is formed on the entire surface of the label except for the required area.

  (9) In still another embodiment of the present invention, the packaging body is a packaging bag containing a sandwich having a triangular side surface.

  According to this embodiment, it is possible to smoothly open the packaging bag to which the label on which the expiration date of the sandwich, the raw material, and the like are printed is attached.

  (10) The label of the present invention is attached to the package of the present invention.

  According to the package of the present invention, the label can be attached and the package can be opened smoothly.

  According to the present invention, since the non-adhesive region is formed in the vicinity of the virtual reference line that overlaps the dividing line on the adhesive surface of the label, the vicinity of the virtual reference line of the label is separated from the package. Compared to the case where there is no non-adhesive area and the entire surface of the label is in close contact with the package, the operating force when opening effectively acts near the virtual reference line that overlaps the dividing line, It becomes easy to open along the virtual reference line.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of a packaging body according to an embodiment of the present invention as viewed from the back side. In this embodiment, the packaging body 1 is described as applied to a packaging bag 1 in which a sandwich is packaged.

  The packaging bag 1 is configured by stacking a plurality of transparent packaging films and heat-sealing a required portion such as a peripheral portion, and stores a sandwich having a triangular side surface.

  On the back surface 1a of the packaging bag 1, a pair of dividing lines DL, DL for opening the packaging bag 1 are formed in parallel with a gap in the width direction. In this embodiment, the pair of dividing lines DL and DL are formed by perforations. Each dividing line DL, DL is formed in a straight line symmetrical with respect to the center in the width direction of the back surface 1 a of the packaging bag 1.

  Above the pair of dividing lines DL, DL, a tab 3 that serves as a knob at the time of opening operation is formed in a semicircular arc shape or the like so as to be connected to each upper end of the pair of dividing lines DL, DL. .

  Inside the back surface 1a side of the packaging bag 1, an inner sheet piece (not shown) is overlapped, and a required portion is heat-sealed and sealed.

  A label 4 on which product information such as a shelf life, a raw material name, a price, and a barcode is printed is pasted on the back surface 1a of the packaging bag 1 on which the opening knob 3 and the pair of dividing lines DL and DL are formed. It is worn.

  The label 4 of this embodiment is rectangular, and as shown in FIG. 2, the center in the width direction (left and right direction in FIG. 2) matches the center in the width direction of the back surface 1 a of the packaging bag 1. It is stuck. The width of the label 4 is larger than the distance between the pair of dividing lines DL and DL on the back surface 1a of the package 1, and is attached so as to cover the pair of dividing lines DL and DL.

  Since the label is attached so that the center in the width direction coincides with the center in the width direction of the back surface 1a of the packaging bag 1 as described above, both sides in the width direction of the label are separated by the dividing lines DL. , DL extend with a width equal to the outside in the width direction.

  A consumer who has purchased the sandwich performs an opening operation so as to pick and hold the knob 3 at the upper part of the back surface 1 a of the packaging bag 1. Thereby, the packaging film and the inner sheet of the back surface 1a are divided along a pair of dividing lines DL, DL extending in the vertical direction, and a portion between the dividing lines DL, DL is separated from the back surface 1a of the packaging bag 1. And open it.

  Since the label 4 is stuck on the back surface 1a of the packaging bag 1 so as to cover the dividing lines DL, DL, when the consumer picks the knob 3 and pulls it downward to open it, the label 4 is attached. It will interfere with smooth opening.

  Therefore, the label 4 of this embodiment is configured as follows so as not to prevent opening as much as possible.

  In the conventional label attached to the packaging bag 1, the back surface is an adhesive surface, and an adhesive layer is formed on the entire surface as an adhesive layer. 1 is attached to the back surface 1a.

  On the other hand, in this embodiment, in order to prevent the opening of the packaging bag 1 from being hindered by the label 4, instead of using the entire back surface of the label 4 as an adhesive layer, a required region is The area has no adhesive strength. Specifically, in the required area on the back surface of the label 4 having the pressure-sensitive adhesive layer formed on the entire surface, a process for invalidating the pressure-sensitive adhesive force of the pressure-sensitive adhesive layer, that is, a so-called gluing process is formed. ing.

  FIG. 3 is a schematic sectional view of a part of the label 4 in the width direction according to this embodiment.

  In the label 4, a printed layer 6 on which product information or the like is printed is formed on the surface of the base material 5, and a pressure-sensitive adhesive layer 7 is formed on the entire back surface of the base material 5 serving as an adhesive surface. The base material 5 consists of paper, a synthetic paper, a resin film etc., for example.

  In this embodiment, on the pressure-sensitive adhesive layer 7 on the back surface of the label 4, an adhesive layer 8 to which an adhesive process has been applied is formed in a required region described later to form a non-adhesive region. For example, the pasting layer 8 is formed by printing a conventionally known pasting agent.

  In order to determine a required region to be non-adhesive region by applying a glue process, a plurality of label samples in which the areas to be glued are changed are produced, and the produced label samples are provided on the back surface of the packaging bag 1. Attaching to the packaging film on which the tab 3 and the dividing lines DL and DL are formed, which is included in 1a, the ease of opening when the tab 3 is pulled down and opened, and the end of the label The lift from the packaging film was evaluated by a sensory test.

  FIG. 4 is a rear view of the label 4 for explaining a formation pattern of a non-adhesive region on which a pasting process is performed in the sample of the produced label 4. In FIG. 4, the hatched area is a non-adhesive area NR in which the adhesive layer 8 that invalidates the adhesive force of the adhesive layer 7 formed on the entire back surface is formed, and is hatched. The white area that is not present is the adhesive area AR where the pressure-sensitive adhesive layer 7 is exposed.

  In FIG. 4, the broken line attached to the label 4 is a pair of virtual reference lines that are assumed to overlap the pair of dividing lines DL and DL when the label 4 is attached to the back surface 1 a of the packaging bag 1. IL, IL.

  That is, the label 4 is attached so that the pair of virtual reference lines IL and IL overlap the pair of dividing lines DL and DL on the back surface 1a of the packaging bag 1.

  As shown in FIG. 4A, the label 4 of this embodiment is a rectangle having a width W of 60 mm and a length L of 70 mm, and a width W1 between the pair of virtual reference lines IL and IL is 30 mm. The widths W2 between the virtual reference lines IL and IL and one end in the width direction are equal to 15 mm.

  In the sample of the produced label 4, the non-adhesive regions NR and NR are both symmetrical with respect to the virtual center line CL at the center in the width direction (left and right direction in FIG. 4), and each virtual reference line It was formed in the vicinity of IL and IL, respectively. Further, the non-adhesive regions NR and NR were formed with the same width over the entire length of the label 4 in the longitudinal direction (vertical direction in FIG. 4).

  Here, the area of the label 4 is an intermediate area extending across the width W1 between the pair of virtual reference lines IL and IL, and an area outside the intermediate direction in the width direction. ) For one side area over the width W2 and the other side area over the width W2 on the other side (right side) in the width direction.

  The formation patterns of the non-adhesive regions NR and NR in the plurality of samples of the label 4 can be basically classified into three formation patterns shown in FIGS. 4 (a), (b), and (c).

  That is, FIG. 4A shows a case where the non-bonding regions NR and NR are formed outside the corresponding virtual reference lines IL and IL, that is, outside the adjacent virtual reference lines IL and IL in the width direction. There are cases where the intermediate region is formed on both sides, that is, on one side (left side) region and the other side (right side) region. In this case, each end NR1 on the inner side in the width direction of each non-adhesion region NR may be on the corresponding virtual reference line IL.

  FIG. 4B shows a case where the non-adhesion regions NR and NR are formed so as to straddle the corresponding virtual reference lines IL and IL. In this case, one non-adhesion region NR is formed between the intermediate region and one side. The other non-adhesive region NR is formed across the intermediate region and the other side (right side) region.

  FIG. 4C shows a case where the non-adhesion regions NR and NR are formed inward in the width direction of the corresponding virtual reference lines IL and IL. The non-adhesion regions NR and NR are formed in the intermediate region. This is the case of forming each. In this case, each one end NR2 on the outer side in the width direction of each non-adhesion region NR may be on the corresponding virtual reference line IL.

  As described above, the non-adhesion regions NR and NR are formed symmetrically with respect to the center line CL. Therefore, by specifying the position of one non-adhesion region NR, the position of the other non-adhesion region NR is also the same. Will be identified.

  Here, the formation position of one non-adhesive region NR in the sample of the label 4 was defined as follows. That is, as shown in FIG. 4, the virtual reference line IL is set to the reference position “0 (mm)”, and the distance from the virtual reference line IL to the corresponding non-adhesion region NR is set to “D1 (mm)”. As shown in FIG. 4A, the case where the non-adhesion region NR is in the one side region outside the virtual reference line IL is defined as “+”, and as shown in FIG. The case where it is in the intermediate region on the inner side is defined as “−”. In FIG. 4B, since the non-adhesion region NR is on the virtual reference line IL which is the reference position, D1 is “0 (mm)”.

  In addition, the distance from one end in the width direction to the non-adhesion region NR in one region was set to “D2 (mm)”.

  As described above, the positions where the non-adhesive regions NR and NR whose positions are defined are changed are different. 1-No. 12 samples of 12 types of labels 4 were prepared, and the ease of opening and the lifting from the packaging film at the end of the label were evaluated by a sensory test.

  In this sensory test, the produced label sample is attached to the packaging film constituting the back surface 1a of the packaging bag 1 on which the knob 3 and the dividing lines DL and DL are formed, and the knob 3 is pulled down and opened. The ease of opening at the time of carrying out and the float of the edge part of the label from a packaging film were evaluated.

  The ease of opening, that is, the ease of tearing is determined by picking and pulling the knob 3 and slowly opening it until the upper end of the attached label 4 is reached. Was slowly pulled down, and the ease of tearing at that time was evaluated in three stages: “good (◯)”, “possible (Δ)”, and “impossible (×)”.

  Moreover, the floating from the packaging film at both end portions in the width direction of the label 4 was evaluated in three stages: “good (◯)”, “possible (Δ)”, and “impossible (×)”.

  In addition, together with the 12 types of label samples produced, a conventional example label in which the entire back surface of the label is an adhesive surface was also evaluated.

  FIG. 5 is a diagram illustrating a label sample including a conventional example and an evaluation result thereof.

  FIG. 5 shows the above-described D1 and D2 indicating the formation position of the non-adhesive region, and the label region corresponding to FIG. 4 in the longitudinal direction of the label is divided into an intermediate region having a width W1 (= 30 mm) and a width. One side region of W2 (= 15 mm) and the other side region of width W2 (= 15 mm) are shown. In this label area, the non-adhesion area NR is indicated by diagonal lines, the adhesion area AR is indicated by white background, and the width (mm) of each area is indicated by a numerical value below the adhesion area AR.

  For D1 and D2, the distance between the pair of virtual reference lines DL and DL, that is, the ratios (D1 / W1) and (D2 / W1) to the width W1 of the intermediate region are also shown.

  In FIG. 5, for example, in the conventional example, the entire area of the label is an adhesive area, and the intermediate area, the one side area, and the other side area of the label area are all white, and D1 and D2 cannot be defined. In the conventional example, the ease of opening was “impossible (×)”, the end of the label did not float, and “good (◯)”.

  For example, sample no. In the label 1, the formation pattern of the non-adhesive region NR corresponds to the above-described FIG. 4A, and in the label region, the non-adhesive region NR having a width of 5 mm is hatched in one side region and the other side region. It is shown in This sample No. In the label 1, the adhesive region AR having a width of 5 mm is shown in white on both sides of the non-adhesive region NR having a width of 5 mm in the one side region and the other side region. Therefore, this sample No. In the label 1, D1 shown in FIG. 4A is “+5 (mm)”, and D2 is “5 (mm)”.

  For example, sample no. In the label 5, the formation pattern of the non-adhesive region NR corresponds to FIG. 4B, and the label region includes the non-adhesive region NR straddling the one side region and the intermediate region, and the intermediate region And the non-adhesive region NR straddling the other side region are indicated by oblique lines. Each non-adhesion region NR has a width of 5 mm on the intermediate region side and a width of 5 mm on one side region or the other side region. Further, it is shown that the width from each end in the width direction of the label to the non-adhesion region NR is 10 mm. Therefore, this sample No. In the label of 5, D1 is “0 (mm)”, and D2 is “10 (mm)”.

  For example, sample no. In the label No. 11, the formation pattern of the non-adhesive region NR corresponds to FIG. 4C. In the label region, the non-adhesive region NR having a width of 5 mm is hatched in the middle region. . This sample No. In the label No. 11, in the middle region, the adhesive region AR having a width of 5 mm is shown in white on the outside of the non-adhesive region NR having a width of 5 mm in the width direction. Therefore, this sample No. In the label of 11, D1 shown in FIG. 4C is “−5 (mm)”, and D2 is “20 = 15 + 5 (mm)”.

  A sample in which the non-adhesive region NR is formed across the corresponding virtual reference line IL, that is, the non-adhesive region NR straddles the one side region and the intermediate region, and straddles the intermediate region and the other side region. Sample No. formed respectively. The labels 5 and 9 were “good (◯)” for ease of opening. In order to facilitate opening as described above, the non-adhesive region NR is preferably formed in the vicinity thereof across the corresponding virtual reference line IL.

  In the sample No. 2 in which the non-adhesive region NR is formed from the intermediate region to the outer region. Among the labels 1-4, 6-8, sample No. Except for the labels of 3 and 6, the ease of opening was “good (◯)”. The labels 3 and 6 were all “open (Δ)” for ease of opening.

  Sample No. whose openability was “good (◯)”. In each of the labels 2 and 8, D1 is “0”, and the non-adhesion region NR is formed from the virtual reference line IL that is the reference position. Similarly, the sample No. whose opening was easy was “good (◯)”. In the label No. 4, D1 is “+2”, the distance from the virtual reference line IL to the outer non-adhesive region NR is 2 mm, and the ease of opening is also “good (◯)”. Sample No. In the label No. 7, D1 is “+4”, the distance from the virtual reference line IL to the outer non-adhesion region NR is 4 mm, and the ease of opening is also “good (◯)”. Sample No. In No. 1, D1 is “+5”, and the distance from the virtual reference line IL to the outer non-adhesion region NR is 5 mm.

  As described above, the sample numbers of “0 (mm)”, “2 (mm)”, “4 (mm)”, and “5 (mm)” are the distances from the virtual reference line IL to the corresponding non-adhesion region NR. Each of the labels 2, 8; 4, 7, and 1 is preferable because the ease of opening is “good (◯)”.

  On the other hand, Sample No. whose ease of opening was “possible (Δ)”. In the label No. 3, D1 is “+7”, the distance from the virtual reference line IL to the outer non-adhesive region NR is 7 mm, and the ease of opening is also “possible (Δ)”. Sample No. In the label No. 6, D1 is “+9”, and the distance from the virtual reference line IL to the outer non-adhesive region NR is 9 mm.

  As described above, the sample No. in which the distance from the virtual reference line IL to the corresponding non-adhesion region NR is within “5 (mm)”. Each of the labels 2, 8, 4, 7, and 1 is easy to open, but the distance from the virtual reference line IL to the corresponding non-adhesive region NR is “good (◯)”. Sample No. exceeding “5 (mm)”. In the labels 3 and 6, the ease of opening was “OK (Δ)”.

  Therefore, in order to facilitate opening, the non-adhesion region NR is preferably in the vicinity of the distance from the corresponding virtual reference line IL within 5 mm which is the first predetermined distance. The first predetermined distance is “0.17”, that is, “17”%, when expressed as a distance between the pair of virtual reference lines IL and IL, that is, a ratio to the width W1 (= 30 mm) of the intermediate region.

  Sample No. Each of the labels 3 and 6 is easy to open ("△"), and is easier to open than "No (x)" that is easy to open in the conventional example. Yes.

  Therefore, in order to make it easier to open compared to the conventional example, the first predetermined distance is changed to “5 (mm)”, and sample No. 3 may be “7 (mm)” or “9 (mm)”. When expressed as a ratio to the distance between the pair of virtual reference lines IL and IL, “23 (%)” or “30 (%) ) ”.

  That is, the non-adhesion region NR is formed in the vicinity of the distance from the corresponding virtual reference line IL within 9 mm, preferably 7 mm, and more preferably 5 mm. This distance is 30% of the distance between the pair of virtual reference lines IL and IL, preferably 23%, and more preferably 17%.

  The non-adhesive region NR is a sample No. formed in the middle of the corresponding virtual reference line IL, that is, in the intermediate region. Among the labels 10 to 12, sample No. The label No. 10 was “good (◯)” for ease of opening. For the labels 11 and 12, the ease of opening was “impossible (×)”.

  Sample No. whose openability was “good (◯)”. In the label No. 10, D1 is “0”, and the non-adhesion region NR is formed from the virtual reference line IL that is the reference position. On the other hand, Sample No. whose opening ease was “impossible (×)”. In the label No. 11, D1 is “−5”, the distance from the virtual reference line IL to the inner non-adhesion region NR is 5 mm, and the ease of opening is also “impossible (×)”. Sample No. No. 12, D1 is “−7”, and the distance from the virtual reference line IL to the inner non-adhesion region NR is 7 mm.

  When the non-adhesive region NR is formed inward of the corresponding virtual reference line IL as described above, the sample No. Like the label of 10, it is preferable that D1 is “0”, that is, it is formed inward from the virtual reference line IL.

  Sample No. When the distance from the virtual reference line IL to the inner non-adhesive region NR is 5 mm as in the case of the label 11, the ease of opening is “impossible (×)”. The distance to the non-bonded region NR needs to be at least less than 5 mm, and needs to be less than 17% of the distance between the pair of virtual reference lines IL and IL.

  Sample No. in which the non-adhesive region NR is formed in the outer region of the intermediate region. Among the labels 1 to 9, sample No. Except for the 6 and 7 labels, there was no lift from the packaging film at the end of the label, and both were “good (◯)”. The labels 6 and 7 were found to be lifted from the packaging film at the end portions, and were “available (Δ) to impossible (×)”.

  Sample No. whose end float was “possible (Δ) to impossible (×)”. 6 and 7, D2 is “1” mm, and the distance from each end in the width direction of the label to the non-adhesion region NR is 1 mm. In other words, the adhesive region AR is only 1 mm wide from the end of the label to the non-adhesive region NR.

  In contrast, sample no. Each of the labels 3 and 4 has D2 of “3” mm, and the distance from the end in the width direction of the label to the non-adhesive region NR is 3 mm. In other words, an area with a width of 3 mm from the end of the label to the non-adhesion area is the adhesion area AR. Sample No. The labels 1, 8, and 9 each have D2 of “5” mm, and the distance from the end in the width direction of the label to the non-adhesive region NR is 5 mm. In other words, a region having a width of 5 mm from the end of the label to the non-adhesive region NR is an adhesive region. Sample No. Each of the labels 2 and 5 has D2 of “10” mm, and the distance from the end in the width direction of the label to the end NR2 on the adjacent side of the non-adhesive region NR is 10 mm. In other words, a region having a width of 10 mm from the end of the label to the non-adhesive region NR is an adhesive region.

  In this way, the distance from the end of the label to the non-adhesive region NR is 1 mm. In the labels 6 and 7, the width of the adhesive region AR at the end of the label is as narrow as 1 mm, so that the end is lifted off from the packaging film, whereas the label end to the non-adhesive region NR. Sample No. whose distance is 3 mm or more. In the labels 1 to 5, 8, and 9, no lifting from the packaging film at the end of the label was observed. Therefore, the distance from each one end in the width direction of the label to the adjacent non-adhesion region NR is preferably 3 mm or more which is the second predetermined distance, and this 3 mm is the distance between the pair of virtual reference lines IL and IL. 10%.

  Therefore, the second predetermined distance from each one end in the width direction of the label to the adjacent non-adhesion region NR is preferably 3 mm or more and 10% or more of the distance between the pair of virtual reference lines IL and IL.

  FIG. 6 is a rear view corresponding to FIG. 2 of another embodiment of the present invention.

  In this embodiment, cuts 11 and 11 are formed at positions corresponding to the upper ends of the pair of virtual reference lines IL and IL of the label 4.

  Accordingly, when the knob 3 at the upper back of the packaging bag 1 is picked and opened along the pair of dividing lines DL, DL so as to be pulled downward, the notches 11, 11 are connected to the dividing lines DL, DL. Will be located, and the portion where the label 4 is attached can be more smoothly divided and opened. In addition to the upper end of the label 4, the cut 11 may be formed at a position corresponding to the lower end of the virtual reference lines IL and IL of the label 4.

  Further, as shown in FIG. 7, the notches 11 and 11 are shifted in the width direction of the label 4 to form three or more at the upper end and the lower end of the label 4, and the label 4 is attached to the packaging bag 1. However, it may be possible to divide along one of the cuts 11 and 11 even if it is slightly deviated.

  In the above embodiment, the dividing line DL is constituted by perforations, but is not limited to perforations, and may be constituted by half cuts or through holes.

  In the above embodiment, as shown in FIG. 3, the pressure-sensitive adhesive layer 7 is formed on the entire back surface, and the adhesive layer 8 is formed in a required region on the back surface of the label 4 to form a non-adhesive region. As another embodiment of the present invention, the pressure-sensitive adhesive layer 7 is formed on the back surface of the label 4 except for the required region, that is, the required region is a region where the pressure-sensitive adhesive layer 7 is not formed. The required area may be a non-adhesive area by so-called pressure-sensitive adhesive pattern coating.

  As long as the package to which the label is attached is cut along the dividing line and opened, the configuration for opening is not limited to the above embodiment, but is arbitrary.

  Further, the package is applicable not only to packaging bags for sandwiches but also to packaging bags and packaging containers for packaging rice balls and other foods.
