Description

The present invention relates to a display strip for mounting and displaying a plurality of bags enclosing products, and more particularly to a display strip capable of re-suspending a product once removed.

Merchandise such as snacks is usually sold in the form of a pillow package (vertical pillow, horizontal pillow) packaged in a bag. Bags enclosing products in this way are often sold side by side on store shelves. However, according to this method, it is necessary to manually display one bag at a time on the display shelf, and there is a place restriction that it can only be displayed and sold on a predetermined display shelf.

On the other hand, a display method for products that does not require a display shelf is known as strip-back display. As shown in FIG. 5, the strip-back display is an display form in which a plurality of products B are attached to a tape material (display strip S) having a predetermined width and suspended. This display form does not require a display shelf and can be displayed and sold at any place such as a store cash register or a hotel reception.

Conventionally, as the display strip, for example, the adhesive strength of the adhesive tape, such as an adhesive tape or an adhesive tape that has been punched in advance at a predetermined position of a tape made of paper or resin, and the adhesive tape is pasted from the back surface. For example, Patent Document 1 discloses a method of attaching a bag enclosing a product to a display strip. This type of display strip has the advantage that it can be re-bonded after the product once attached is removed.
However, these display strips have a problem that it is difficult to automate the process of attaching a bag enclosing a product to the display strip using a machine. That is, even if such a display strip is to be automated while the adhesive tape is exposed, the tape cannot be fed freely because it sticks to a roller or the like when passing through the machine. On the other hand, even when the adhesive surface is covered with a release sheet or the like, it is difficult to automate the product because the operation for attaching the product is complicated. In addition, there is a problem in that dust and dirt may adhere to the surface of the adhesive tape and the appearance may be impaired.

On the other hand, a display strip has been proposed in which a heat-sealed layer is provided on one side so that a bag enclosing a product can be directly heat-sealed and bonded. If this display strip is used, it is extremely easy to automate the process of attaching a bag enclosing a product to the display strip continuously with a series of steps of enclosing the product in a bag.

However, in a product exhibit that combines a product-encapsulated bag and a display strip in this way, once the product-enclosed bag is removed from the display strip, it can be attached to the display strip again. For example, the bag must be heat-sealed again to the display strip with a hand sealer or the like, which is very troublesome and it is difficult to reattach the bag once removed in the store to the display strip. .
It is often possible for a person who wishes to purchase a product, etc., to pick up a bag containing the product once and then reconsidering the product to return to its original state. It was not possible to deal with such a case.

An object of the present invention is to provide a display strip capable of easily automating a process of attaching a bag enclosing a product and easily reattaching a bag enclosing the product once removed. And

As a means for achieving the above-mentioned object of the present invention, it is composed of at least a base material layer and a sealant layer, and the sealant layer is a heat whose outermost layer does not exhibit adhesiveness at room temperature and gives heat sealability. A heat sealing layer containing a meltable resin, the inner layer of the heat sealing layer has a layer structure composed of two or more adhesive layers containing an adhesive exhibiting adhesiveness at room temperature, and a product is enclosed In the display strip for mounting and displaying a plurality of bags that are arranged side by side, in the present invention, in the heat seal layer, the bag is connected to the heat seal layer in the vicinity of a portion where the bag enclosing the product is bonded. The display strips have cuts extending from one end to the other end in a direction perpendicular to the direction in which the products are lined up, so that the product bonded by heat sealing is enclosed. When the bag is removed, the heat-seal layer present in the region partitioned by the uppermost nearest cut and the lowermost nearest cut at the position where the bag is heat-sealed reliably breaks down and the adhesive The most important feature is that the layer is exposed.
The present invention is described in detail below.

The display strip of the present invention comprises at least a base material layer and a sealant layer.
The sealant layer is a heat seal layer containing a heat-meltable resin that gives heat sealability, and the inner layer of the heat seal layer is sticky at room temperature. It has a layer structure composed of two or more pressure-sensitive adhesive layers containing an agent.
In the display strip of the present invention having such a configuration, the heat-sealable resin in the heat-seal layer is melted by heat-sealing the heat-seal layer that forms the outermost surface of the sealant layer and the bag in which the product is enclosed. The bag can be combined.

The heat-meltable resin contained in the heat seal layer is not particularly limited as long as it does not exhibit adhesiveness at room temperature and can exhibit sufficient heat seal properties. For example, polypropylene, propylene and other Copolymers with olefins (ethylene, alpha olefins having 4 to 12 carbon atoms), low density polyethylene (including metallocene linear low density polyethylene), ethylene vinyl acetate copolymer, ethylene methacrylate ester copolymer, etc. Things. Among these, metallocene linear low density polyethylene or ethylene vinyl acetate copolymer is preferable. The heat seal layer may have a single-layer structure or a multilayer structure composed of a plurality of layers.

When the heat-meltable resin is an ethylene vinyl acetate copolymer, the heat seal layer preferably further contains a tackifier.
The tackifier is not particularly limited. For example, at least one selected from the group consisting of rosin resins, terpene resins, aliphatic hydrocarbon resins, alicyclic hydrocarbon resins, and aromatic hydrocarbon resins. A seed resin is preferably used.

The rosin resin is not particularly limited. For example, rosin, rosin derivative, rosin ester, gum rosin, wood rosin, tall oil rosin, distilled rosin, hydrogenated rosin, dimerized rosin, polymerized rosin, natural rosin glycerol ester, modified rosin Glycerol ester, natural rosin pentaerythritol ester, modified rosin pentaerythritol ester, light wood rosin glycerol ester, hydrogenated rosin glycerol ester, polymerized rosin glycerol ester, hydrogenated rosin pentaerythritol ester, phenolic modification of rosin Examples include pentaerythritol ester.

The terpene resin is not particularly limited, and examples thereof include terpenes, phenolic terpenes, modified terpenes, α-pinene polymers, β-pinene polymers, dipentene polymers, terpene-phenol copolymers, and the like.

The aliphatic hydrocarbon resin is not particularly limited, and examples thereof include polymers mainly composed of mono- or diolefins having 4 to 5 carbon atoms such as 1-butene, isobutylene, butadiene, and 1,3-pentadiene. Can be mentioned.

The alicyclic hydrocarbon resin is not particularly limited. For example, a resin obtained by polymerizing a cyclized and dimerized diene component in a spent C4-C5 fraction, a cyclic monomer such as cyclopentadiene is polymerized. Resin, hydrogenated dicyclopentadiene resin, hydrogenated petroleum resin and the like.

The aromatic hydrocarbon resin is not particularly limited, and examples thereof include vinyltoluene, indene, styrene polymer, α-methylstyrene copolymer, and the like.

Moreover, as said tackifier, commercially available things, such as what was described in USP6117945, can also be used, for example.

Moreover, since the said heat seal layer does not show adhesiveness at normal temperature, it also has a role as a mask layer which coat | covers the adhesive layer formed inside the said heat seal layer. By having such a mask layer, the display strip of the present invention does not exhibit adhesiveness before heating, and the process of heat sealing the bag can be easily automated.

Although it does not specifically limit as thickness of the said heat seal layer, As shown in the below-mentioned Example, it is preferable to set it as the thickness of 30-50 micrometers. If the thickness is too thick, the inner pressure-sensitive adhesive layer may not be exposed when the bonded bag is removed, and the bag may not be reattached.

The pressure-sensitive adhesive layer is an inner layer of the heat seal layer and contains a pressure-sensitive adhesive that exhibits adhesiveness at room temperature.
Although it will not specifically limit as said adhesive if it shows adhesiveness at normal temperature, It is preferable that it is a rubber adhesive or an acrylic adhesive.

By having an adhesive layer containing an adhesive that exhibits adhesiveness at room temperature, the display strip of the present invention is such that the adhesive force of the adhesive layer is added to the bonding force between the heat seal layer and the bag by heat sealing. Therefore, even when the weight of the product enclosed in the bag is heavy, it can be reliably held.
As will be described in detail later, when the display strip of the present invention is removed, the heat seal layer of the portion to which the bag is attached is peeled off together with the bag to expose the adhesive layer. The removed bag can be re-adhered to the exposed pressure-sensitive adhesive layer.

Although it does not specifically limit as thickness of the said adhesive layer, A preferable minimum is 10 micrometers and a preferable upper limit is 300 micrometers. When it is less than 10 μm, when the attached bag is removed, the pressure-sensitive adhesive layer is peeled off together with the heat seal layer, and the bag may not be reattached. If it exceeds 300 μm, the adhesive strength is too high, and it becomes difficult to remove the bag in which the commodity once attached is enclosed.

The base material layer is not particularly limited, but preferably has sufficient strength from the application to suspend a large number of products and has heat resistance that does not melt or deteriorate during heat sealing, for example, Biaxially stretched polypropylene (OPP), biaxially stretched polyethylene terephthalate, metal foil, paper, nonwoven fabric, woven fabric, or a laminate thereof is suitable. Especially, it is preferable that it is a laminate in which a woven fabric is laminated on a resin film or paper made of the above biaxially stretched polypropylene or biaxially stretched polyethylene terephthalate, and the woven fabric has two biaxially stretched polypropylene or biaxially stretched. More preferably, it is a laminate having a structure sandwiched between resin films made of polyethylene terephthalate or between two sheets of paper. Since the mechanical strength of the display strip of the present invention becomes extremely high, for example, even when a hole punch for hanging is formed on the display strip of the present invention and a hook is hooked on the hole punch, the hole punch strength Therefore, the hole punch portion is not easily damaged.

Although it does not specifically limit as said woven fabric, The thing formed by knitting a conventionally known method, such as plain weave, twill weave, mojiori, etc., is used.
The weave density of the woven fabric is not particularly limited, but is preferably about 6 to 20 pieces / inch. If there is an appropriate spacing between the warp yarns or weft yarns, when the resin film is laminated, a part of the resin constituting the resin film penetrates and integrates into the gaps of the warp and weft yarns of the woven fabric. The adhesion between the cloth and the resin film is improved.

The woven fabric is not particularly limited, but those made of polyolefin yarn such as high density polyethylene, low density polyethylene, metallocene linear low density polyethylene, isotactic polypropylene, syndiotactic polypropylene, etc. are required for display strips. It is suitable from the viewpoints of performance and adhesiveness with the resin film.
The polyolefin yarn may be made of a single resin, but may be a composite yarn in which a high-melting point polymer and a low-melting point polymer are combined as necessary. If such a composite yarn is used, both excellent mechanical strength and adhesiveness with a resin film can be achieved.

The polyolefin yarn is not particularly limited, and for example, multifilament yarn, monofilament yarn, flat yarn, split yarn or the like can be used. Of these, flat yarn and split yarn are preferred.
Here, the flat yarn is a yarn formed by slitting a film formed by an extrusion molding method or the like to a predetermined width, and then performing a stretching process and a heat treatment. Further, the split yarn is a yarn obtained by further dividing the flat yarn. Flat and split yarns are known to have very high tensile and tear strengths.
The fineness of the polyolefin yarn is not particularly limited, and those usually used in the range of about 100 to 5000 d can be used.

Although it does not specifically limit as a resin film which comprises the said base material layer, What consists of polyester, polyolefin, etc. is suitable. Among these, a polyester film is preferable because it has appropriate rigidity and mechanical strength.
In addition, when the adhesiveness of a polyester film and the said woven fabric is low, you may laminate | stack a polyester film and a woven fabric through a polyolefin film.

The method for producing the substrate layer is not particularly limited. For example, a method of forming a resin film layer by extruding a polymer on the woven fabric; a method of dry laminating a resin film on the woven fabric; And a method of laminating a woven fabric while extruding polyethylene onto a resin film such as polyester or paper.

Although it does not specifically limit as thickness of the said base material layer, A preferable minimum is 30 micrometers and a preferable upper limit is 500 micrometers. If it is less than 30 μm, sufficient hole punch strength may not be obtained, and there is a risk of damage when removing a bag enclosing the product, and if it exceeds 500 μm, the base material layer serves as a heat insulating material. Heat may not be sufficiently transferred to the sealant layer during heat sealing.

The sealant layer and the base material layer may be laminated via an adhesive by a known dry laminating method, or may be laminated by a thermal laminating method without using a solvent.

In the display strip of the present invention, it is preferable that the base material layer and the pressure-sensitive adhesive layer are laminated via an intermediate layer made of polyethylene. Since polyethylene is flexible and has a high tensile elongation, it is possible to improve the strength of the entire display strip and the hole punch strength by having an intermediate layer made of polyethylene.
The intermediate layer made of polyethylene can be performed by laminating polyethylene while extruding between the base material layer and the sealant layer. In addition to polyethylene, an ionomer of ethylene- (meth) acrylic acid copolymer or ethylene- (meth) acrylic acid copolymer may be used.

Although it does not specifically limit as thickness of the said polyethylene layer, A preferable minimum is 5 micrometers and a preferable upper limit is 50 micrometers. If the thickness is less than 5 μm, a sufficient strength improvement effect may not be obtained. If the thickness exceeds 50 μm, the thickness of the entire display strip becomes thick, and the heat sealability may be impaired due to the heat insulating effect. .

In the display strip of the present invention, an anchor coat layer is preferably formed between the base material layer and the pressure-sensitive adhesive layer. The adhesive force between the base material layer and the pressure-sensitive adhesive layer is excellent, and peeling between the base material layer and the pressure-sensitive adhesive layer is difficult to occur. The anchor coat layer is not particularly limited, and examples thereof include those made of a conventionally known anchor coat agent such as a polyisocyanate / polyester two-component curable adhesive. The anchor coat layer is formed by coating the anchor coat agent on the resin film surface to be coated with the adhesive.

In the display strip of the present invention comprising the base material layer and the sealant layer, the heat seal layer is surely destroyed when the bag enclosing the product bonded by heat seal is removed. Then, there is a cut in the vicinity of the part where the bag enclosing the product is bonded so that the pressure-sensitive adhesive layer is exposed.

FIG. 1 is a front view schematically showing a part of the display strip of the present invention, and FIG. 2 is a longitudinal sectional view of the display strip shown in FIG.
As shown in FIG. 1 and FIG. 2, the display strip 1 of the present invention has a band-like structure in which a sealant layer 2 is laminated on a base material layer 5 via an anchor coat layer 6, and a product is enclosed thereabove. A hole punch 4 for suspending the display strip 1 of the present invention, to which the bag is attached, is formed.

The sealant layer 2 is composed of a heat seal layer 2a constituting the outermost surface layer and an adhesive layer 2b laminated on the anchor coat layer 6 inside the heat seal layer 2a. On the outermost surface (the side opposite to the adhesive layer 2b), a plurality of cuts 3 are formed at equal intervals in a direction perpendicular to the longitudinal direction of the display strip 1 of the present invention (a direction perpendicular to the direction in which the bags are arranged). .
The break 3 is bonded to the bag enclosing the product so that when the bag enclosing the product bonded by heat sealing is removed, the heat sealing layer 2a is surely broken and the adhesive layer 2b is exposed. In other words, in the display strip 1 of the present invention shown in FIG. 1, the bag in which the product is enclosed is heat-sealed in the region defined by the cuts 3.

In the display strip of the present invention, the cut formed in the heat seal layer is preferably formed in a continuous line shape or a perforated shape.
Further, the shape of the cut is not particularly limited as long as it is a shape that partitions an area in which a bag enclosing a product can be heat-sealed. A display strip such as the cut 3 shown in FIG. In addition to a shape formed at equal intervals in a direction perpendicular to the longitudinal direction (a direction orthogonal to the direction in which the bags are arranged), for example, an arbitrary shape such as a rectangular shape, a circular shape, an elliptical shape, or a track shape may be mentioned. In particular, because of the ease and accuracy of the forming process, as shown by the cut 3 shown in FIG. 1, the shape is formed at regular intervals in the direction perpendicular to the longitudinal direction of the display strip (the direction perpendicular to the direction in which the bags are arranged). Preferably there is.

Since the cut is formed in the heat seal layer of the sealable layer, the heat seal layer is easily broken along the cut. For this reason, when a bag in which a product attached by heat sealing is enclosed in the area defined by the cut is removed, the uppermost nearest cut and the lower nearest cut at the position where the bag is heat sealed together with the bag. The heat seal layer present in the area defined by and is surely broken and peeled off, and the pressure-sensitive adhesive layer is exposed. Then, once removed, the bag can be attached again by adhering it to the exposed adhesive layer.
Thus, according to the display strip of the present invention, since the outermost layer is a heat seal layer containing a heat-meltable resin that does not exhibit tackiness at room temperature and gives heat sealability, the step of attaching the bag to the display strip, It is extremely easy to continuously automate a series of steps of enclosing a product in a bag. On the other hand, once the bag attached to the display strip is removed, the heat seal layer is peeled off along the cut along with the bag, and the pressure-sensitive adhesive layer containing a pressure-sensitive adhesive that is sticky at room temperature is exposed. By adhering the bag to the pressure-sensitive adhesive layer, the bag once removed can be easily reattached without using a hand sealer or the like.

The method for forming the cut is not particularly limited. For example, the cut is formed in advance in the heat seal layer, and the cut is pasted on the pressure-sensitive adhesive layer; the heat seal layer is bonded to the pressure-sensitive adhesive layer. A method of forming the cut in the heat seal layer while pasting together; a method of forming the cut in the slit process in manufacturing the display strip of the present invention, and the like.

The form of the display strip of the present invention is not particularly limited, and examples thereof include a tape form and a sheet form.
Further, like one hole punch 4 of the display strip 1 shown in FIG. 1, a suspension hole (hole punch) for hanging the display strip itself is provided at one end of the display strip of the present invention. preferable. By hooking a fixture to the hole punch, a product display body produced by heat-sealing a bag on the display strip of the present invention can be displayed in a strip-back manner.
Moreover, it is preferable that the said suspension hole is formed only in the upper end of the display strip of this invention. If a suspension hole is also formed at the lower end of the display strip, the product display body may be suspended upside down in a store or the like.

When the hole punch is provided in the display strip of the present invention, the base material layer is preferably configured to include a woven fabric. As described above, when the base material layer includes a woven fabric, the mechanical strength of the display strip of the present invention is extremely high. When a product display body produced by heat-sealing a bag on a display strip is displayed on a strip back, the hole punch portion is less likely to be damaged.

The method for producing the display strip of the present invention is not particularly limited, and a conventionally known method can be used. For example, after forming a pressure-sensitive adhesive layer by coating a base material layer with a pressure-sensitive adhesive paste containing a pressure-sensitive adhesive at normal temperature by a gravure method or a calender method, There is a method of forming a heat seal layer by laminating a film containing a heat-meltable resin that does not exhibit adhesiveness at room temperature and gives heat sealability.

As a bag for enclosing a product to be attached to the display strip of the present invention, any commonly used bag can be used. For example, biaxially oriented polypropylene (OPP) layer / printing layer / polyethylene (PE) layer / aluminum vapor-deposited polyethylene terephthalate (PET) layer / polyethylene (PE) layer / unstretched polypropylene (CPP) layer, transparent vapor-deposited biaxial A bag whose surface is a biaxially stretched polymer, such as a stretched polyethylene terephthalate (PET) layer / printing layer / unstretched polypropylene (CPP) layer, or that has a heat sealable sealant layer on the outermost layer. used. For example, in the United States, heat sealable biaxially oriented polypropylene (OPH) layer / printing layer / polyethylene (PE) layer / aluminum-deposited heat sealable biaxially stretched as the outermost layer having a heat-sealable sealant layer What consists of a polypropylene (OPH) layer is used, and such a bag can be suitably attached to the display strip of this invention.

A method for attaching a bag enclosing a product to the display strip of the present invention is not particularly limited. For example, it is preferable to attach the bag by the procedure shown in FIG. In this method, first, a bag in which a product is enclosed is placed so that the front side of the bag B is in contact with the display strip 1, and then the upper portion of the bag B is heat sealed to bond the bag to the display strip 1 (FIG. 3a). At this time, it is necessary that the crimping part 7 at the upper part of the bag B is in a region defined by the cut formed in the heat seal layer constituting the outermost surface of the display strip 1 of the present invention.
When a bag B enclosing a predetermined number of products is joined to the display strip 1, the bag B enclosing each product is turned upside down around the crimping portion 7 so that the surface of the bag B is opposite to the display strip 1. (Fig. 3b). In this state, if one end of the display strip 1 is suspended and displayed on a hook or the like, the crimping portion 7 between the bag B and the display strip 1 is as shown in FIG. By pulling in the direction, the display strip 1 can be easily detached from the display strip 1 together with the heat seal layer in the region defined by the above-described cuts.

A merchandise display body in which a bag enclosing merchandise is attached to the display strip of the present invention described above is also one aspect of the present invention.

In the commodity display body of the present invention, the sealing strength between the bag and the display strip is not particularly limited, but a preferable lower limit is 1 N / 30 mm, and a preferable upper limit is 50 N / 30 mm. If it is less than 1 N / 30 mm, the product may fall due to its own weight depending on the weight of the product, and if it exceeds 50 N / 30 mm, it may not come off even if the bag enclosing the product is pulled in a suspended state. is there. A more preferable lower limit is 5 N / 30 mm, and a more preferable upper limit is 30 N / 30 mm.

Note that the sealing state and peeling state between the bag and the display strip can vary greatly depending on the sealing conditions. The sealing conditions change depending on the temperature at the time of sealing, the contact time of the seal jaw, the contact pressure, and the like, and may also change depending on the shape of the seal jaw. As the shape of the sealing jaw, for example, the shape shown in FIG. 4 can be used. Therefore, it is preferable to select the optimum sealing conditions according to the resin composition forming the sealant layer of the display strip and the material of the surface layer of the bag. The width of the sealing jaw is selected according to the desired length of the adhesive surface between the display strip and the bag surface, and this length is from the beginning of peeling when peeling the bag from the display strip to the completion of peeling. Determining the distance substantially.

Next, a display strip according to another embodiment of the present invention will be described.

Further, the woven fabric is not particularly limited, but those similar to those described for the base layer of the display strip of the present invention described above are preferably used.

In the display strip of the present invention according to another aspect, the sealant layer may have the same configuration as the sealant layer of the display strip of the present invention described above, except that no cut is formed. That is, the outermost layer of the sealant layer is not sticky at room temperature, and a heat seal layer containing a heat-meltable resin that gives heat sealability, and the inner layer of the heat seal layer is sticky at room temperature. It has a layer structure consisting of two or more pressure-sensitive adhesive layers containing the pressure-sensitive adhesive shown.

The display strip of the present invention according to another aspect is provided with a hole punch for hanging at the top thereof. That is, a product display body in which a bag enclosing a product in the display strip of the present invention is attached by heat sealing is displayed by hooking the hole punch on the hook.

The shape of the hole punch is not particularly limited as long as it is a shape that allows the hook to pass therethrough, and includes any shape such as a circle, an ellipse, a square, a track, or a combination thereof. Also, the size is not particularly limited, and is appropriately determined in consideration of the size of the hook formed on the bag, the size of the bag, etc. Is about 5 mm and the upper limit is about 10 mm.

The layer is peeled off with the bag, the adhesive layer underneath is exposed, and the bag once removed can be re-bonded.
Further, by increasing the adhesive strength between the heat seal layer and the bag, the heat seal layer in the portion where the bag is attached can be surely peeled off together with the bag. In this case, when the bag is removed, a large stress acts on the hole punch portion. However, in the display strip of the present invention according to another aspect, since the base material layer includes a woven fabric, the hole punch strength is excellent, and the hole punch portion is affected by an impact when the bag is removed. Even if a large stress acts on the hole punch portion, the hole punch portion is not damaged.
In addition, the display strip of the present invention according to another embodiment having the base material layer including the woven fabric has a notch-like notch in the hole punch due to a cause that the knife used for forming the hole punch is cut off. Even when it is formed, the hole punch strength does not extremely decrease.

Using a strip back device, heat-sealing the bag material in which 100 g of the contents were sealed in the display strips produced in Examples 1 to 5 and Comparative Examples 1 and 2 at a heat sealing temperature of 120 ° C. and a sealing time of 250 msec. An adhesion sample was prepared. In addition, as a strip back device, what was disclosed by Unexamined-Japanese-Patent No. 2004-90949 is used, and as a bag material, a film with a total thickness of 50 μm of sealable OPP / ink / polyethylene / sealable OPP is used from the surface. did.

(1) Measurement of initial seal strength With respect to the prepared adhesive sample, the seal strength was measured at a tensile speed of 300 mm / min using a tensile tester (manufactured by Toyo Seiki Seisakusho, Strograph V1-C). The results are shown in Table 1.

(2) Presence or absence of exposure of adhesive surface When the bag was peeled off by measuring the initial seal strength, it was visually confirmed whether or not the adhesive layer was exposed by peeling off the heat seal layer together with the bag. The results are shown in Table 1.

(3) Evaluation of re-adhesiveness The bag material once peeled off was physically adhered again to the location where the display strip was peeled off at a pressure of 2 kg, and it was judged whether or not it could be hung. The results are shown in Table 1.

As shown in Table 1, in Examples 1 to 4 in which a cut was formed in the heat seal layer constituting the sealant layer, the adhesive layer was exposed because the heat seal layer was also peeled off by peeling off the bag material. Re-adhesion of the bag material was possible.

ADVANTAGE OF THE INVENTION According to this invention, the automation of the process which attaches the bag with which the goods were enclosed is easy, and the display strip which can attach again the bag with which the goods once removed were enclosed can be provided easily.
