  In the display suspension packaging, information on the article is described on the mount, and even if the customer peels off the article covered with a plastic film or plastic sheet, it is described on the mount. There is a need for a display-hanging package that does not lose article information due to peeling of the article. In order to make it possible for a consumer to easily peel off an article from the mount without losing information on the article on the mount due to peeling, for example, it can be realized by weakening the adhesive strength between the article and the mount. . However, when the adhesive strength between the article and the mount is weakened, the durability of the display hanging packaging becomes a problem. In particular, in the case of a display suspension packaging including an article having a large mass, there arises a problem that the mount and the article are peeled off due to the mass of the article.

  In addition, it is possible to peel off the layers other than the adhesive layer, and the display hanging so that the information on the article on the mount is not lost due to the peeling of the article by making the adhesive strength between the article and the mount sufficient. A package can be produced. However, a plastic film or plastic sheet that is packaged on an article (hereinafter, a plastic film that is packaged on an article may be referred to as an exterior film, and a plastic sheet that is packaged on an article may be referred to as an exterior sheet) is a smooth film such as polyethylene resin. In addition, since the film or sheet has a small polarity, the physical anchor effect is insufficient and the chemical bonding force cannot be expected. Therefore, the adhesion strength between the exterior film or exterior sheet and the adhesive layer becomes insufficient, and there arises a problem that peeling at the interface between the exterior film or exterior sheet and the adhesive layer occurs.

It is an object of the present invention to provide a method for producing a display-suspended package that is not lost by peeling and that does not peel off at the interface between the outer film or the outer sheet and the adhesive layer.

  As a result of intensive studies to solve the above-mentioned problems, the present inventors have made the structure of the mount used for the display suspension packaging body a specific structure, and applied the hot melt adhesive on the exterior film or exterior sheet. It was found that the above-mentioned problems can be solved by bonding with a peeling portion on the surface of the mount after forming the sheet, and the present invention has been completed.

The mount 11 regarding this embodiment is demonstrated using FIG.2 and FIG.3. The mount relating to the present invention is not limited to the mount 11 shown in FIG. 2, and the mount 11 shown in FIG. 2 is an example for specifically explaining the mount related to the present invention. As shown in FIG. 2, half-cut grooves 111 having a depth less than the thickness direction of the mount 11 are continuously formed on the mount 11 with two points on one side of the mount 11 as a starting point 111a and an end point 111b. ing. Further, as shown in FIG. 3, an adhesive layer 13 is formed on the surface of the peeling portion 112 surrounded by the half cut groove 111 and one side of the mount 11. The mount 11 according to the present invention is not limited to the mount 11 of FIG. 2, and a circumferential shape formed on the surface of the mount 11 with a half-cut groove 111 having a depth less than the thickness direction of the mount 11. The peeling part 112 is formed, and the peeling part 112 should just be peelable from the half cut groove | channel 111 with the peeling of the articles | goods 12 as a starting point. For example, even if the half-cut groove 111 on the surface of the mount is not continuously formed with two points on one side as a starting point 111a and an end point 111b, the half-cut groove 111 is oval or oval on the surface of the mount The egg shape or the like, or only a part of the shape may be a U-shape or the like.

  The role of the half cut groove 111 relating to the present embodiment will be described with reference to FIGS. FIG. 3 is a cross-sectional view of the package 1 before the article 12 is peeled from the mount 11. When the article 12 is peeled from the mount 11, the mount 11 is cut in the horizontal direction on the surface of the mount 11 with the half-cut groove 111 as a starting point. Then, as shown in FIG. 5, the article 12 is peeled off together with the adhesive layer 13 and the surface layer of the peeling portion 112. On the other hand, FIG. 4 is a cross-sectional view of the package 1 after the article 12 is peeled from the mount 11. As shown in FIG. 4, the packaging body 1 after the article 12 is peeled off has the article 12 and the adhesive layer 13 since the mount 11 is cut in the horizontal direction on the surface of the mount 11 starting from the half-cut groove 111. It will be in the state which the surface layer of the peeling part 112 peeled.

  Since the packaging body 1 according to the present embodiment is a packaging body in which the article 12 and the mount 11 can be peeled from the half-cut groove 111, the article 12 and the mount 11 can be used without weakening the adhesive strength of the adhesive layer 13. Can be easily peeled off. Further, the mount 11 is cut in the horizontal direction on the surface of the mount 11 starting from the half-cut groove 111, and the back surface layer of the peeling portion 112 exists on the mount 11 as a remaining portion, and only the surface layer of the peeling portion 112 is cleaned. Can be peeled off. Therefore, even when information on the article is written on the surface layer other than the peeling portion 112 or on the entire back surface, the article 12 described on the entire surface layer other than the peeling portion 112 or the entire back surface due to the peeling of the article 12. No information will be lost.

  The depth of the half cut groove 111 is preferably 33% or more and 75% or less of the thickness of the mount 11. By setting the depth of the half-cut groove 111 in such a range, the back surface layer of the peeling portion 112 exists as the remaining portion, and only the surface layer of the peeling portion 112 can be peeled cleanly.

  Further, the shape of the half-cut groove 111 on the surface of the mount 11 relating to the present embodiment may be a vertically long inverted U shape with the bottom side vertically below in the hanging direction as shown in FIG. preferable. As shown in FIG. 5, when the article 12 is peeled from vertically above in the hanging direction, it is possible to peel from the vertically long inverted U shape, so that only the peeling portion 112 can be peeled cleanly. .

  As a material used for the mount 11, paper generally used for a display hanging packaging can be used. Also, the paper is generally made of fibers extracted from the pulp, and the paper fibers are aligned in the machine flow direction (paper grain) while the paper is being manufactured. However, the paper grain of the mount 11 is along the vertical direction of the mount 11. Preferably it is. By making the paper used for the mount 11 the vertical direction of the mount 11, it becomes easy to peel the surface layer of the peeling portion 112 in the vertical direction of the mount 11.

  In addition, the mount 11 may be a single-layer mount made of paper, but if necessary, it may be a mount in which aluminum is vapor-deposited on PET and bonded to paper, or a mount in which aluminum foil and paper are bonded. . By providing the mount 11 with a layer formed of PET, aluminum or the like, the durability of the mount 11 can be made more preferable.

  Moreover, it is preferable that another half-cut groove 113 that is substantially orthogonal to the half-cut groove 111 is further formed as in the mount 11 shown in FIG. By providing another half-cut groove 113, the risk that the surface layer other than the peeling portion 112 is peeled can be further reduced.

It is preferable that tackifying resin is contained in 40 to 80 mass parts from a viewpoint made to make it.

  The softening point of the hot melt adhesive according to the present embodiment may vary depending on the use environment temperature, but it is preferably 80 ° C. or higher and 160 ° C. or lower in consideration of outdoor use. When the softening point is 80 ° C. or higher, it becomes easy to balance the adhesive force and the cohesive force. On the other hand, by setting the softening point to 160 ° C. or lower, it becomes easy to maintain tack even in a low temperature atmosphere. In the specification, the softening point is a temperature determined by a method defined in JIS K 6863. A more preferable range of the softening point of the hot melt adhesive according to this embodiment is 90 ° C. or higher and 140 ° C. or lower, and a more preferable range is 100 ° C. or higher and 130 ° C. or lower.

  The hot melt adhesive according to this embodiment is preferably a foamed hot melt adhesive. By using the foamed hot melt adhesive, the elasticity of the adhesive layer can be increased and the followability between the article 12 and the adhesive layer 13 can be improved. Further, by increasing the followability, the contact area with the peeling portion 112 can be increased, and the adhesive force can be improved.

  The timing of foaming the hot melt adhesive is not particularly limited, but from the viewpoint of improving productivity and managing the quality with high accuracy, the hot melt adhesive is hot immediately before forming the adhesive layer 13, during coating, or immediately after coating. It is preferred to foam the melt adhesive. Among these, foaming is more preferable immediately before coating or at the time of coating. The adhesive layer 13 is obtained by applying a molten hot melt adhesive to a predetermined position of the exterior film or the exterior sheet.

  The method and apparatus for incorporating air bubbles into the hot melt adhesive are not particularly limited, but a method of foaming the hot melt adhesive by blowing gas is suitable. Further, a heat decomposable foaming agent may be added to the hot melt adhesive so that fine bubbles are generated when the adhesive layer 13 is formed.

  For example, a device for blowing a gas into a hot melt adhesive and foaming it includes, for example, a heated stirring container that melts and heats the hot melt adhesive under normal pressure or pressure, and a volatile substance that introduces a volatile substance such as a gas into the heated stirring container. The agitation conditions (number of revolutions, etc.) according to the viscosity of the hot melt adhesive, etc., the substance supply means, the sensor for monitoring the temperature and viscosity in the heated stirring container, the stirring means provided in the heated stirring container An apparatus having a controllable control unit can be exemplified. Although a volatile substance is not specifically limited, Inert gas, such as nitrogen and argon, can be illustrated and nitrogen can be used conveniently.

  Moreover, you may use the gas which interacts between the component of an adhesive agent and a molecule | numerator, and can hold | maintain inside an adhesive bond layer. Depending on the type of the adhesive layer, carbon dioxide can be exemplified as such an example. The gas may be introduced at normal pressure, but it is efficient to carry out under pressure. It is also possible to use supercritical carbon dioxide or the like.

  From the viewpoint of efficiently introducing bubbles, the melt viscosity of the hot melt adhesive when the gas is blown is preferably in the range of 1,000 to 50,000 mPa · s, more preferably 5,000. It is the range of -20,000 mPa * s, Most preferably, it is the range of 5,000-15,000 mPa * s. The foaming temperature depends on the type of hot melt adhesive used, but is usually 120 to 180 ° C, and preferably 120 to 150 ° C. After forming the foamed hot melt adhesive, it is usually returned to room temperature. Thereby, an adhesive agent solidifies and a foaming part is also fixed.

The appropriate foaming ratio of the hot melt adhesive can vary depending on the application and needs, and can be arbitrarily set. From the viewpoint of enhancing the versatility with respect to the shape of the article, it is preferable that the mass ratio when filled in a 100 cc container in the molten state is in the range of 1.1 to 10 in the following formula. More preferably, it is 1.5-5, Especially preferably, it is the range of 1.5-3.
V1 / V2 Formula (where V1 is the mass of 100 cc of the unfoamed hot melt adhesive, and V2 is the mass of 100 cc of the foamed hot melt adhesive)

  In the adhesive layer 13 according to the present embodiment, the bonding strength between the packaged article 12 and the peeling portion 112 is preferably higher than the delamination strength between the front surface layer and the back surface layer in the peeling portion 112. By making the bonding strength between the outer article 12 and the peeling portion 112 in this way, when the article 12 is peeled from the mount 11, the mount 11 is placed in the horizontal direction on the surface of the mount 11 with the half-cut groove 111 as a starting point.

<Manufacturing method of display suspension packaging>
One Embodiment of the manufacturing method of the package 1 of this invention is described using FIG. In the manufacturing method of the package 1 of the present embodiment, first, a hot melt adhesive (adhesive layer 13) is formed on the exterior film or exterior sheet of the article 12 on the article 12 that is exteriorized with a plastic film or plastic sheet. Since the exterior film or the exterior sheet is generally a smooth film having a small polarity, the physical anchor effect is insufficient and a chemical bonding force cannot be expected. Therefore, the bonding strength at the interface between the exterior film or exterior sheet and the adhesive layer 13 is improved by first applying the hot melt adhesive on the exterior film or exterior sheet of the article 12 to form the adhesive layer 13. Can be made.

  And the manufacturing method of the package 1 of this embodiment joins with the peeling part 112 on the surface of the mount 11, after forming a hot-melt-adhesive (adhesive layer 13) on the exterior film or exterior sheet | seat of the articles | goods 12. It is characterized by that. Since the surface of the mount 11 is a sheet having a surface roughness and a polarity that is greater than that of the exterior film or sheet, such as paper, metal foil, or PET, the surface roughness and polarity are greater than those of the exterior film or the exterior sheet. Therefore, even if the hot melt adhesive (adhesive layer 13) is formed on the exterior film or exterior sheet of the article 12 and then joined to the release portion 112 on the surface of the mount 11, the release portion 112 on the surface of the mount 11 There is little decrease in the bonding strength at the interface with the adhesive layer 13. Therefore, even when the article 12 is peeled from the mount 11, the outer film or the exterior sheet of the article 12 and the peeling portion 112 of the mount 11 do not peel, and the surface of the peeling portion 112 starts from the half-cut groove 111. Article 12 can be peeled from the layer.
