Abstract

PROBLEM TO BE SOLVED: To provide a pouch package with a tack label having a high advertisement effect and suitable for automatic sticking by mechanization.SOLUTION: A main surface wall 10 of a pouch body 1 has a main part 10a where a separated distance between a pair of the main surface walls 10 enlarges and a shoulder part 10b where the separated distance reduces between the main part 10a and an upper end seal part 13, the enlargement and reduction in the separated distance being caused by filling of a content. A hardly peelable adhesion part 22 and an easily peelable adhesive part 21 are provided on a rear surface of a tack label 2, a lower side region of the tack label 2 is made to adhere to the main part 10a of the main surface wall 10 by positioning the hardly peelable adhesion part 22 in the main part 10a of the main surface wall 10 and an upper region of the tack label 2 is separated from the shoulder part 10b without following the shape of the shoulder part 10b of the main surface wall 10 and is protruded upward by facing off of at least a part of the easily peelable adhesion part 21 against the shoulder part 10b of the main surface wall 10.

Description

  The present invention relates to a pouch package with a tack label in which a tack label is attached to a pouch package filled with contents such as beverages.

  Conventionally, the applicant has already proposed a campaign label as a tack label attached to a pouch package (Patent Document 1 below). Specifically, a campaign label is attached to the front wall of the pouch body in which side gussets are provided between both side portions of the pair of main surface walls.

  On the other hand, it is also conceivable to make the pouch package more noticeable by devising the way of attaching the tack label. For example, the main surface wall of the pouch main body has a main portion having a large separation distance between the pair of main surface walls due to filling of the contents and a shoulder portion in which the separation distance decreases from the main portion toward the upper end seal portion. However, it is conceivable that the upper region of the tack label protrudes upward from the main portion of the main surface wall without sticking to the pouch body. In other words, an adhesive layer is provided only on the lower region of the back surface of the tack label and adhered to the main portion of the main surface wall, and the upper region of the tack label is separated from the shoulder portion of the main surface wall. In this case, since the upper region of the tack label appears to protrude upward from the main surface wall, there is an advantage that the advertising effect is enhanced.

  However, attaching the tack labels to the pouch packaging by hand manually has a problem that the work load is large. Accordingly, it is required to attach the tack label automatically by mechanization, but since the pouch package after filling the contents is easily deformed, it is difficult to attach the tack label by the machine. Therefore, the tack label will be attached to the flat pouch body that is not filled with the contents, but if the predetermined area of the tack label is not adhered to the pouch body, it will be sent to the subsequent process in sequence. On the way, the tack label may peel off from the pouch body or break.

JP 2002-234084 A

  Therefore, the present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a pouch package with a tack label that has a high advertising effect and is suitable for automatic attachment by mechanization.

  The present invention has been made to solve the above problems, and the pouch packaging body with a tack label according to the present invention is composed of a flexible sheet, and side gussets are formed between both side portions of a pair of main surface walls. A pouch package with a tuck label in which a pouch body, which is provided and has a spout attached to the upper end seal portion, is filled with contents, and a tack label is attached to the main surface wall of the pouch body, The main surface wall has a shape having a main portion having a large separation distance between the pair of main surface walls and a shoulder portion in which the separation distance decreases between the main portion and the upper end seal portion by filling the contents. The back surface of the tack label is provided with a hardly peelable adhesive portion and an easily peelable adhesive portion, and the lower peelable adhesive portion is located at the main portion of the main surface wall so that the lower region of the tack label is the main portion of the main surface wall. In The at least part of the easily peelable adhesive portion faces the shoulder portion of the main surface wall, so that the upper region of the tack label protrudes upward away from the shoulder portion without being along the shoulder portion of the main surface wall. It is characterized by that.

  In the pouch packaging body with a tack label having the above structure, the hardly peelable adhesive portion on the back surface of the tack label is located in the main portion of the main surface wall, and at least a part of the easily peelable adhesive portion on the back surface of the tack label is A tack label is affixed to the pouch packaging so as to face the shoulder of the main wall. Accordingly, the tack label has its lower region firmly attached to the main portion of the main surface wall, and its upper region protrudes upward away from the shoulder portion of the main surface wall so that it is easily noticeable. Furthermore, when a tack label is attached to a flat pouch body before the contents are filled, the tack label is attached to the pouch body by a hardly peelable adhesive portion and an easily peelable adhesive portion. Therefore, after the tack label is automatically pasted by the machine, the tack label is peeled off or damaged from the flat pouch body not filled with the contents in the middle of sequentially sending to the subsequent process. Is prevented.

  Moreover, the pouch packaging body with a tack label according to the present invention is a pouch body that is composed of a sheet having flexibility, side gussets are provided between both side portions of a pair of main surface walls, and a spout is attached to the upper end seal portion. A pouch package with a tuck label in which the contents are filled and a tack label is adhered to the main surface wall of the pouch main body, the main surface wall of the pouch main body being spaced between a pair of main surface walls by filling the contents The main part having a large separation distance and the shoulder part from which the separation distance decreases toward the upper end seal part from the main part, and the tack label has a sticking sheet laminated on the back surface of the label body It is a structure, a hard-peeling adhesive part is provided in the back of a sticking sheet, a hard-peeling adhesive part and an easy-peeling adhesive part are provided between the label body and the sticking sheet, and sticking sheet Is attached to the main part and the shoulder part of the main wall by the hard peelable adhesive part on the back side, and the hard peelable adhesive part between the layers is located on the main part of the main face wall, so that the lower side of the label body The region is attached to the main part of the main surface wall via the sticking sheet, and at least a part of the easily peelable adhesive layer between the layers faces the shoulder of the main surface wall so that the upper region of the label main body is the main surface wall. It is characterized in that it protrudes upward away from the shoulder without being along the shoulder.

  In the pouch package with a tack label having the above structure, the peelable adhesive portion between the label main body and the sticking sheet is located at the main portion of the main surface wall, and at least a part of the easy peelable adhesive portion between the layers. The tuck label is attached to the pouch packaging body so as to face the shoulder of the main wall. Therefore, the label main body of the tack label has its lower region firmly attached to the main portion of the main surface wall via the sticking sheet, and its upper region protrudes upward away from the shoulder portion of the main surface wall. It is easy to stand out. Furthermore, if a tack label is stuck on the flat pouch main body before the contents are filled, the label main body is in a state of being laminated on the sticking sheet by the hardly peelable adhesive portion and the easy peelable adhesive portion. Therefore, after the tack label is automatically pasted by the machine, the tack label is peeled off or damaged from the flat pouch body not filled with the contents in the middle of sequentially sending to the subsequent process. Is prevented.

  In the above configuration, when the peelable adhesive portion is a strong adhesive portion having a strong adhesive force, and the easily peelable adhesive portion is a weak adhesive portion having a weak adhesive force, the flat pouch body expands by filling the contents. Then, the weakly bonded portion is automatically peeled off, and the upper area of the tack label or the upper area of the label body automatically protrudes upward.

  In addition, the hard-peeling adhesive part is composed of an adhesive having excellent water resistance, and the easy-peeling adhesive part is composed of an adhesive having poor water resistance. When performing heat sterilization such as retort sterilization using steam or water vapor, or when performing a cooling process using cold water after heat sterilization, the easily peelable adhesive part made of an adhesive having poor water resistance is automatically peeled off. Thus, the upper area of the tack label or the upper area of the label body automatically protrudes upward.

  The width of the side gusset (also referred to as the gusset depth; the length from the side edge of the pouch body to the bent portion of the side gusset folded inwardly) is L, and the width of the side seal part (pouch body). The width of the seal part at the side of the upper part is m and the width of the upper seal part is h. The boundary between the shoulder part and the main part is located at the portion of L−m + h from the upper edge of the pouch body ( For example, see FIG. Actually, the boundary between the shoulder and the main part is a gentle arc, but the position represented by the above formula is the boundary (ridgeline) between the shoulder and the main part, and the shoulder is located above the boundary. The lower side is defined as the main part. Moreover, about the shape of a main surface wall, the external force is not provided but the state expand | swelled naturally by content filling is assumed.

  As described above, the pouch package with a tack label according to the present invention is conspicuous because the upper region of the tack label or the upper region of the label main body of the tack label protrudes upward, and has a high advertising effect. can get. Also, until the pouch body expands due to contents filling etc., the tack label is securely attached to the flat pouch body by the peelable adhesive part and the easily peelable adhesive part, or the label of the tack label Since the main body is securely attached to the sticking sheet, it is suitable for automatic sticking by mechanization, and the easy peelable adhesive part peels off automatically after filling the contents, so separate peeling work is also required It becomes unnecessary and can be manufactured at low cost.

  Hereinafter, a pouch package with a tack label according to an embodiment of the present invention and a tack label attached thereto will be described with reference to FIGS.

  The pouch package with a tuck label shown in FIG. 1 is a pouch body 1 filled with contents such as a liquid or jelly-like food or drink or a fluid such as a detergent. It is. The pouch body 1 is formed in a bag shape from a flexible sheet. Specifically, a side gusset 11 that includes a front wall and a rear wall that are a pair of main surface walls 10 and that is folded inward between the left and right side portions of both main surface walls 10 is provided. Side seal portions 12 extending in the vertical direction (vertical direction) are formed by heat-sealing both side edge portions of the side gusset 11 and side edge portions of both main surface walls 10. The upper end portions of both main surface walls 10 are heat-sealed to form an upper end seal portion 13 extending in the horizontal direction (horizontal direction), and the mouth member is sandwiched between the upper end portions of both main surface walls 10. A cylindrical spout 3 is attached by heat sealing. In FIG. 1 and FIG. 6, the heat-sealed portion is cross-hatched. The spout 3 is located at the approximately horizontal center (approximately the center in the width direction) of the pouch main body 1, and is positioned between the bent portions of both side gussets 11, that is, at a position where it does not interfere with the side gussets 11. The bent portion 11a of the side gusset 11 is indicated only by the broken line in FIG. 1 and is indicated by the broken line over the entire length in FIG. Further, a cap 4 for closing the upper end opening is screwed to the spout 3. Generally, the cap 4 is screwed after the pouch body 1 is filled with contents from the upper end opening of the spout 3.

  The pouch body 1 is in a flat state until the contents are filled, but when the contents are filled, the pouch body 1 automatically expands in the front-rear direction due to the flexibility of the sheet, and is in a natural state in which no external force acts. In the predetermined shape. Specifically, as shown in FIG. 2, both main surface walls 10 include a main portion 10a having a large distance between the main surface walls 10 (a distance in the front-rear direction) and a substantially constant amount, and the main portion 10a. The shape has a shoulder portion 10b in which the separation distance decreases from the portion 10a toward the upper end seal portion 13. In FIG. 1, a boundary 10c (ridge line) between the shoulder portion 10b and the main portion 10a is indicated by a two-dot chain line. Actually, as shown in FIG. 2, the boundary 10c between the shoulder 10b and the main part 10a has a gentle arc shape, but the upper side of the boundary 10c shown by the two-dot chain line in FIG. The shoulder portion 10b and the lower side are the main portion 10a. The boundary 10c between the shoulder portion 10b and the main portion 10a is determined by the depth of folding inward of the side gusset 11. 1 and 6, the dimensions of each part are shown. When the width of the side gusset 11 is L, the width of the side seal part 12 is m, and the width of the upper seal part 13 is h, the shoulder part 10b and The boundary 10c with the main part 10a is located in the part which becomes L-m + h from the upper edge of the pouch main body 1. FIG. The width L of the side gusset 11 is the length from the side edge of the pouch body 1 to the bent portion 11 a of the side gusset 11. In FIGS. 1 and 6, a two-dot chain line 14 is an imaginary line showing an inclination angle of 45 degrees with respect to the upper end seal portion 13.

  Here, as a sheet | seat which comprises the pouch main body 1, an outer layer which consists of a biaxially stretched polyester film, a biaxially stretched polyamide film, etc., a low density polyethylene, a high density polyethylene, a linear low density polyethylene, a polypropylene, a metallocene type | system | group, for example A multi-layer laminate film consisting of an inner layer made of a heat-fusible resin such as polyethylene is used, and if necessary, gas barrier properties such as a film on which an inorganic substance such as ethylene vinyl alcohol copolymer, aluminum foil, or silicon oxide is deposited. What laminated | stacked the film etc. is also used. The spout 3 is integrally formed by molding from a synthetic resin that can be heat-sealed on the inner surface of the sheet constituting the pouch body 1, for example, a heat-sealable resin such as polyethylene or polypropylene.

  A tack label 2 is attached to the main surface wall 10 (front wall) of the pouch body 1. The tack label 2 is, for example, rectangular, and includes a label main body 20 on which characters and designs are printed on one side of a label base material as shown in FIG. 3 and an adhesive layer formed on the back surface of the label main body 20. It is configured. The label substrate is not particularly limited as long as it is usually used for tack labels. For example, polyester resins such as polyethylene terephthalate, olefin resins such as polyethylene and polypropylene, styrene resins such as polystyrene, polyvinyl chloride, A synthetic resin film made of a vinyl resin such as an ethylene-vinyl alcohol copolymer can be used as appropriate. The adhesive layer is formed on the entire back surface of the label body 20. The adhesive layer is divided into two regions. One of them is a weakly bonded part 21 as an easily peelable adhesive part located on the upper side of the label body 20, and the other is a strong adhesive part 22 as a hardly peelable adhesive part located on the lower side of the label body 20. It is. That is, the adhesive layer is composed of a weakly bonded portion 21 and a strongly bonded portion 22, which are partitioned vertically by dividing lines 23 that extend in a straight line in the lateral direction. The ratio of the weakly bonded portion 21 and the strongly bonded portion 22 is arbitrary, but it is preferable that the weakly bonded portion 21 is set to half or less of the entire area of the label main body 20.

  In FIG. 3 (a), the adhesive layer is simply illustrated as a substantially uniform thickness throughout, but in detail, a weakly bonded portion 21 is configured as shown in FIG. 3 (b). . That is, the adhesive layer 24 is formed with a substantially uniform thickness on the entire back surface of the label main body 20, and an adhesive layer is further provided on the upper portion of the adhesive layer 24 corresponding to the region of the weakly bonded portion 21. A covering layer 25 that partially covers 24 is formed. In the present application, the adhesive is a concept including an adhesive. Each of the coating layers 25 is partially arranged in a dot shape (island shape) such as a circle, a mesh shape, or other predetermined shape, and a portion of the adhesive layer 24 covered with the coating layer 25. The adhesive strength (adhesive strength) is lost, and the adhesive strength of the portion of the adhesive layer 24 that is exposed without being covered with the coating layer 25 is maintained. 3B and 4A illustrate a dot-like covering layer 25 such as a circle, and FIG. 4B illustrates a mesh-like covering layer 25. Alternatively, as shown in FIG. 5A, the weak adhesive portion 21 may be formed by forming the coating layer 25 in the center and leaving the adhesive layer 24 around the coating layer 25. In this case, the adhesive force of the weakly bonded portion 21 is determined by the adhesive layer 24 having a total of three sides. Further, as shown in FIG. 5B, the covering layer 25 of FIG. 5A can be divided into left and right by the adhesive layer 24 along the vertical direction to increase the adhesive force of the weakly bonded portion 21. In the case of FIG. 5B, if the adhesive layer 24 is additionally left as shown by a two-dot chain line, the adhesive force of the weak adhesive portion 21 can be further increased, and the adhesive layer 24 to be left is left. The adhesive strength can be adjusted by the shape and area of the. The shape of the adhesive layer 24 to be left may be formed not only vertically and horizontally but also obliquely, and is arbitrary. In FIG. 4 and FIG. 5, the area of the coating layer 25 is marked with many dots as hatching. Moreover, in FIG. 4, the division line 23 is shown with the dashed-two dotted line. As described above, when the covering layer 25 is partially disposed, the overall adhesive force of the upper portion of the adhesive layer 24 is reduced, and the weakly bonded portion 21 is configured. On the other hand, since such a coating layer 25 is not formed on the lower part of the adhesive layer 24, the original adhesive force of the adhesive layer 24 is exhibited, and the strong adhesive portion having a stronger adhesive force than the weak adhesive portion 21. 22 is configured. Such a coating layer 25 can be formed, for example, by applying ultraviolet curable ink by printing means. In addition, the ratio (density) of the area where the covering layer 25 is formed in the weakly bonded portion 21 takes into consideration various conditions such as the type of adhesive (adhesive), the thickness of the layer, the size and thickness of the label body 20, and the like. However, if the area ratio of the coating layer 25 in the weak adhesive portion 21 is 30%, the coating layer 25 is not formed in the weak adhesive portion 21 and the adhesive layer 24 is formed. The ratio of the exposed area is 70%. Increasing the area ratio where the coating layer 25 is formed in the weakly bonded part 21 decreases the adhesive force of the weakly bonded part 21, while conversely decreasing the area ratio increases the adhesive force of the weakly bonded part 21. It is possible to easily adjust the adhesive force of the weakly bonded portion 21 by adjusting. Further, the adhesive force of the weakly bonded portion 21 can be adjusted by changing the thickness of the covering layer 25 instead of or together with the area ratio. Various known water-resistant adhesives (adhesives) can be used as the adhesive layer 24.

  Although such a tack label 2 is attached to the main surface wall 10 of the pouch body 1, the attachment position in the horizontal direction is not particularly limited (in this embodiment, it is attached to a substantially central position). As for the sticking position in the vertical direction, as shown in FIG. 1, the dividing line 23 of the weakly bonded portion 21 and the strongly bonded portion 22 is a position at a distance H from the upper edge of the pouch body 1. The position of the distance H from the upper edge is a position slightly lower (several millimeters, specifically 3 to 5 millimeters) than the position of the boundary 10c between the shoulder portion 10b and the main portion 10a described above. Therefore, it can be expressed as H = L−m + h + 3 to 5 millimeters. Although it is possible to further shift the position (height) of the lane marking 23 downward, when shifting to the upper side, the position of the boundary 10c between the shoulder 10b and the main portion 10a is set as the upper limit. That is, it is preferable that the strong adhesion portion 22 is not positioned on the shoulder portion 10 b of the main surface wall 10.

  Thus, the tack label 2 is stuck so as to straddle the boundary 10c between the shoulder portion 10b and the main portion 10a, and the strong adhesion portion 22 is located at the main portion 10a of the main surface wall 10. Therefore, the lower region of the label main body 20 (tack label 2) is attached to the upper portion of the main portion 10a of the main surface wall 10. On the other hand, the upper region of the label main body 20 with the weakly bonded portion 21 is separated from the shoulder portion 10b. That is, most of the weakly bonded portion 21 is in a state of facing the shoulder portion 10b, and the upper region of the label main body 20 is not along the shoulder portion 10b but protrudes upward away from the shoulder portion 10b. Yes. The upper end of the tack label 2 is below the upper edge of the upper end seal portion 13 of the pouch body 1.

  Further, the tack label 2 is not attached after the contents are filled in the pouch body 1, but is attached to the pouch body 1 in a flat state before the contents are filled as shown in FIG. Is done. The tuck labels 2 may be attached to the single-wafer type pouch main body 1 one by one, but the tuck labels 2 are spaced at regular intervals while feeding the continuous strip in the longitudinal direction before the pouch main body 1 is cut. The tack label 2 may be stuck sequentially every time, and in any case, the tack label 2 is automatically stuck by a machine.

  Until the contents are filled, the entire tack label 2 is in a sticking state. That is, not only the strong bonding portion 22 but also the weak bonding portion 21 is in a stuck state. Then, when the contents are filled from the spout 3 and the pouch body 1 is expanded, the weakly bonded portion 21 is automatically removed from the shoulder portion 10b of the pouch body 1 by the shape change of the main surface wall 10 of the pouch body 1 as shown in FIG. The upper region of the tack label 2 automatically protrudes upward. That is, the label main body 20 has such a rigidity that the weak adhesive portion 21 can be peeled off from the pouch main body 1 without following the shape change of the main surface wall 10 of the pouch main body 1. The upper region is automatically separated from the shoulder 10b. Since the tack label 2 may be attached to the flat pouch body 1, it is suitable for automatic attachment by a machine. Moreover, since the entire surface of the tack label 2 is adhered, the tack label 2 is not peeled off from the flat pouch body 1 up to the content filling step. And since the weak adhesion part 21 is automatically peeled using the expansion | swelling of the pouch main body 1 by contents filling etc., a separate peeling process becomes unnecessary.

  In the pouch package thus completed, the upper region of the tack label 2 protrudes upward, so that it is easily noticeable and exhibits a high advertising effect. The pouch body 1 itself is often deformed into various shapes in the display state, but in contrast, the tack label 2 has a waist and is firmly upright, so that the product does not change in shape. The tack label 2 appears more conspicuous than in the case of sticking. In addition, since the tack label 2 having a high rigidity is attached to the upper surface of the main surface wall 10 in particular, the upper portion of the main surface wall 10 that is particularly noticeable is reinforced by the tack label 2, and the vicinity of the tack label 2 It becomes easier to see the display of the main surface wall 10 located at the position.

  In this embodiment, the weakly adhesive part 21 and the strong adhesive part 22 are provided as the easily peelable adhesive part and the hardly peelable adhesive part, but the hardly peelable adhesive part is composed of an adhesive excellent in water resistance, You may comprise an easily peelable adhesive part from the adhesive agent (water-soluble adhesive) inferior to water resistance. As an adhesive excellent in water resistance, for example, a heat-sensitive adhesive composed of an ethylene acrylate copolymer or the like can be used, and as an adhesive inferior in water resistance, an acrylic type soluble in hot water or alkaline water can be used. A pressure sensitive adhesive such as an adhesive (acrylic adhesive) can be used.

  And as shown in FIG. 8, the water-resistant adhesive layer 30 which consists of an adhesive agent excellent in water resistance is formed in the whole back surface of the label main body 20, and also the intermediate film 31 is intervened in the upper area | region, and then water-resistant A water-soluble adhesive layer 32 made of an adhesive having poor properties is formed. While the portion where the water-soluble adhesive layer 32 is formed becomes an easily peelable adhesive portion, the portion of the water-resistant adhesive layer 30 which is exposed without being formed with the water-soluble adhesive layer 32 is hardly peelable. Part.

  As described above, when the hardly peelable adhesive portion is the water-resistant adhesive layer 30 and the easily peelable adhesive portion is the water-soluble adhesive layer 32, when filling the pouch body 1 with the contents, the easily peelable adhesive portion is used. Does not peel off, and the easily peelable adhesive part peels off in a process using an aqueous solvent such as hot water, steam, cold water, or alkaline water, such as a subsequent heat sterilization process or cooling process. That is, when performing a process using these aqueous solvents, the hard-to-peel adhesive portion maintains the adhesive force as it is, but the easy-peelable adhesive portion loses the adhesive force or decreases the adhesive force due to these aqueous solvents. Therefore, in the process using these aqueous solvents, the upper region of the tack label 2 is automatically peeled off from the shoulder 10b due to the rigidity of the label main body 20 and protrudes upward. In addition, even when there is no process using these aqueous solvents, or in the case where they are present, it is possible to manufacture by separately incorporating a process using a new aqueous solvent for the purpose of more reliably peeling the easily peelable adhesive part. Good.

  Moreover, although the structure which sticks the label main body 20 directly to the pouch main body 1 with the contact bonding layer which consists of an easily peelable adhesive part and a hard-to-removable adhesive part was demonstrated, the label main body 20 was attached to the pouch main body 1 via the sticking sheet 40. You may make it stick to. Specifically, as shown in FIG. 10, an adhesive layer is formed on the back surface of the label main body 20 in the same manner as described above. That is, the adhesive layer is constituted by an easily peelable adhesive portion made of the weakly bonded portion 21 and a hard peelable adhesive portion made of the strong adhesive portion 22. However, the easily peelable adhesive portion and the hardly peelable adhesive portion may be the above-described water-soluble adhesive layer and water-resistant adhesive layer. And the sticking sheet 40 is laminated | stacked on the contact bonding layer, and also the adhesive layer 41 which consists of a hard-peeling adhesive part is laminated | stacked on the back surface of the sticking sheet 40 further. The strong adhesive portion 22 (hardly peelable adhesive portion) between the label body 20 and the adhesive sheet 40 and the adhesive layer 41 (hardly peelable adhesive portion) on the back surface of the adhesive sheet 40 may be the same adhesive. It may be an adhesive.

  Thus, since the adhesive layer 41 which consists of a hard-peeling adhesive part is provided in the whole back surface of the sticking sheet 40, when the tack label 2 is stuck on the pouch main body 1, the whole sticking sheet 40 will be the pouch main body 1. FIG. It will stick firmly to. And since the easily peelable adhesive part between layers is the weak adhesive part 21, the upper side area | region of the label main body 20 peels from the sticking sheet 40 like FIG. Further, when the easily peelable adhesive portion is a water-soluble adhesive layer, the upper region of the label main body 20 peels from the sticking sheet 40 in a process using an aqueous solvent such as a retort sterilization process. In any case, the whole sticking sheet 40 is stuck to the pouch body 1, and therefore the sticking sheet 40 is stuck not only to the main part 10a but also to the shoulder part 10b. About the sticking position of the tack label 2, it is the same as that of the said embodiment. Therefore, since the interlayer peelable adhesive portion is positioned corresponding to the main portion 10 a of the main surface wall 10, the lower region of the label body 20 is attached to the main portion 10 a of the main surface wall 10 via the sticking sheet 40. Since the majority of the easily peelable adhesive layer between the layers faces the shoulder portion 10b of the main surface wall 10, the upper region of the label body 20 does not extend along the shoulder portion 10b of the main surface wall 10 from the shoulder portion 10b. It will be in the state which separated and protruded upwards. In addition, although the various sheets can be used for the sticking sheet | seat 40 similarly to the label base material of the label main body 20, it is preferable to use a sheet | seat with less rigidity than the label main body 20 (especially the label base material). Change the thickness and material of the sheet to be used so that the rigidity is different.
