Description

  The present invention relates to a method for manufacturing a package with a mount and a package with a mount. More specifically, the present invention relates to a method for manufacturing a package with a mount formed using a hot melt adhesive and a package with a mount.

Conventionally, blister packaging has been frequently used as a packaging form. Blister packaging heats and softens a thin thermoplastic resin plate, accommodates the article in a relatively hard transparent plastic molded to match the shape of the article, and puts the plastic on the mount on which the article name and article information are printed It is the packaging form which affixes. Because of transparent packaging, there is an advantage that the contents can be visually confirmed while packaging the article. However, in recent years, attention has been focused on shrink film packaging as a packaging form that replaces blister packaging from the viewpoint of reducing CO ₂ emissions from packaging materials and reducing the volume of garbage.

  Various methods have been proposed for manufacturing shrink film packaging. For example, in Patent Document 1, (a) a board supply step for supplying a single board onto the conveyor one by one, (b) an adhesive for applying an adhesive with a plate roll to the surface of the board that is supplied and conveyed on the conveyor (C) Mount with a shrink film (heat) by supplying a cylindrical film that can be thermally contracted one by one to the mount on which the adhesive is applied, and sticking to the mount A method for producing a shrinkable film mount is disclosed. Patent Document 2 proposes a method of manufacturing a mount with shrink film (mount with mount capable of heat shrinking) that can arbitrarily change the shape of the mount.

  In Patent Document 3, positioning is easy when inserting an article to be packaged inside a cylindrical shrink film, and after shrink wrapping, there is little wrinkle at the end of the shrink film, and the shrink is unlikely to be a bulged corner. A method for obtaining a mount with a film has been proposed. Specifically, there is disclosed a mount with a shrink film that is attached to a mount by folding a tubular shrink film so as to crush the tube, and when a package is inserted into the tubular shrink film, the cover is attached. In order to be able to contact and position the package, a positioning adhesive portion is provided from both ends of the opening toward the center of the opening so as to partially close the opening at the upper end opening or the lower end opening of the folded cylindrical shrink film. A configuration is disclosed.

  Further, Patent Document 4 proposes a method for manufacturing a mount with a shrink film that is attached to the mount by changing the angle of the cylindrical shrink film regardless of the shape of the mount. Specifically, (a) a cutting process for cutting a long cylindrical shrink film into a fixed shape, (b) a film transporting process for transporting the cut cylindrical shrink film one by one, ( c) Adhesive application step of applying an adhesive to the cut cylindrical shrink film that has been transported, (d) A mount is pasted to the cylindrical shrink film coated with the adhesive via the adhesive. The manufacturing method provided with the base_sheet | mounting_paper sticking process to wear is proposed.

  Patent Document 5 proposes a method using a reactive hot melt adhesive in order to provide a package in which the packaged shrink film does not peel off even at high temperatures.

According to the shrink film packaging, as described above, since the cost reduction, volume reduction, CO ₂ reduction derived from the packaging material, and the like can be realized as compared with the blister packaging, its use is increasing in recent years. However, in blister packaging, the edge of the plastic molded in accordance with the shape of the article is joined to the mount with an adhesive, so the shape of the article does not matter at the time of joining, whereas in shrink film packaging, the article And the backing sheet are fixed through the adhesive layer and the heat-shrinked film (heat-shrinked shrink film), so that it is easily affected by the shape of the article, and there are restrictions on the article to be packaged. By applying various shrink film packaging manufacturing methods as described above, applicable products to be packaged are expanding. However, in the market, a technology that can further expand the articles to be packaged has been demanded.

There was a case. According to the method disclosed in Patent Document 3, since the positioning means for inserting the article is provided, the effect of preventing misalignment can be expected for a stable shape such as a bottle. However, there is an article group group that cannot solve the problem of misalignment for articles with complicated shapes, articles with poor stability, articles with multiple insertions, etc., and the articles targeted for shrink film packaging were restricted. . Moreover, even if the article is a target for shrink film packaging by a conventional method, the front position of the article may be shifted or the position of the article may be inclined, resulting in a packaging failure.
On the other hand, according to the method for manufacturing a package with a mount according to the present invention, a hot-melt adhesive capable of reversibly repeating melting and solidification by heat after preliminarily producing a film-wrapped article wrapped with a heat-shrinkable film Since the film wrapping article and the mount are joined using the, the article can be easily fixed at a desired position with respect to the mount regardless of the shape of the article. Accordingly, it is possible to wrap the shrink film even on an article that is conventionally excluded from the object of the shrink film, such as an article having an unbalanced shape, an article that is easy to move, or a plurality of articles.

Further, matters other than matters specifically mentioned in the present specification and necessary for the implementation of the present invention can be grasped as design matters for those skilled in the art based on the prior art in this field. Further, the following embodiments are preferably combined with each other.

[First Embodiment]
FIG. 1A is a schematic explanatory view of a package with a mount according to the first embodiment, and FIG. 1B is a sectional view taken along the line IB-IB in FIG. 1A. Moreover, an example of the manufacturing method of the packaging body with a mount according to the first embodiment will be described with reference to FIGS. 2A to 2C and FIG. 3.

  As shown in FIGS. 1A and 1B, the packaging body 1 with a mount is a packaging article in which a film packaging article 21 is attached to the mount 12 with an adhesive layer 13 interposed therebetween, and the heat-shrinkable film 11 is an adhesive. It is bonded to the mount 12 through the layer 13. The adhesive layer 13 is a hot melt adhesive layer formed using a hot melt adhesive, which will be described in detail later. The packaging body 1 with a mount may have other members without departing from the gist of the present invention. For example, a cushion material for protecting the product from impact, a heat insulating member for protecting the article from heat at the time of forming the adhesive layer 13, a heat radiating member, and the like can be exemplified. The adhesive layer 13 is for bonding the heat-shrinkable film 11 and the mount 12, but the heat-shrinkable film 11 and the mount 12 are not limited to those directly bonded to the adhesive layer 13, A mode in which the adhesive layer 13 is joined via a member such as another sheet formed integrally with the heat-shrinkable film 11 and / or the mount 12 is also included.

  The production of the package 1 with mount includes at least steps 1 to 3 shown in FIG. Specifically, in step 1, the article is packaged with a heat-shrinkable film to obtain a film-wrapped article packaged with the heat-shrinkable film. Next, in Step 2, an adhesive layer is formed on at least one of the heat-shrinked film and the base paper constituting the film packaging article. Thereafter, as step 3, the film packaging article packaged with the heat-shrinked film and the mount are bonded together with a hot melt adhesive layer interposed therebetween.

  The heat-shrinked film 11 plays a role of covering the article 20 by covering at least a part of the article 20 (see FIG. 1A), and is a film obtained by heat-shrinking a so-called shrink film. As in the example of FIG. 1A, the entire side surface portion of the article 20 may be packaged by the heat-shrinkable film 11, only the central portion of the article may be packaged in a belt shape, or the entire article may be packaged. The heat-shrinkable film 11 is preferably colorless and transparent or colored and transparent, but may be non-transparent so that the state of the packaged article can be confirmed. The heat-shrinkable film 11 may be printed with visible character information or the like, or may be printed with various images.

  The heat-shrinkable film 11 is not limited as long as it is obtained by heat-shrinking a heat-shrinkable film such as a stretched film, and any commonly used film can be used without limitation. For example, polystyrene, polyethylene, polypropylene, and polyvinyl chloride can be exemplified. In addition, a polylactic acid-based thermoplastic resin (polyester resin or the like) is also suitable as an environmentally friendly biodegradable film. The heat-shrinkable film 11 may be provided with a perforation 15 as shown in FIG. 1A or an opening 16 formed with two or more rows of perforations according to needs.

  The mount 12 mainly plays a role as a base material for wrapping the article 20 and a role as an information providing unit such as an article name and article information. The mount 12 may be provided with a hanging hole 14 or the like as a display means for the article 20. The material of the mount 12 is not particularly limited as long as the material does not deform when the article 20 is pasted. Preferable examples include polyester films, nylon films, vinylidene chloride, polyolefin films such as polyethylene and polypropylene, or plastic sheets made of laminates thereof, paper, metal sheets, composite sheets made of composite materials, or laminates thereof. The body can be exemplified. For example, a laminate of a plastic film and an aluminum foil may be used. What is necessary is just to select suitably the thickness, raw material, etc. of the base_sheet | mounting_paper 12 according to the mass, size, etc. of the articles | goods 20. FIG. In addition to the flat plate shape, the mount 12 may have a curved surface shape, a bent shape, or the like. Also, an L-shaped or U-shaped mount may be used. Furthermore, in order to make it easy to take out the article 20 from the package 1 with the mount, a perforation or an opening may be provided in a contact portion with the article 20 on the back side of the mount 12 or in the vicinity thereof.

  The adhesive layer 13 has a role of bonding the heat-shrinkable film 11 and the mount 12, and is formed of a hot-melt adhesive layer exhibiting high-melting thermoplasticity that can reversibly repeat melting and solidification by heat. The adhesive layer 13 used in the present invention is solid at room temperature, can be melted by heating, and can be applied to the bonded portion, and is solidified by returning the bonded portion to the normal temperature after application to be bonded to the bonded portion. It demonstrates its power. That is, the adhesive used in the present invention is subjected to a post-treatment process for bonding (such as an aging process or a UV curing process to advance curing by moisture or heat) after the heat-shrinkable film 11 and the base 12 are bonded. This is different from the necessary reactive hot melt adhesive and so-called sealant of high viscosity type. The adhesive layer 13 may be a pressure sensitive adhesive layer.

  The hot melt adhesive of the present invention contains at least a thermoplastic resin and a tackifying resin. The hot melt adhesive preferably contains a wax. In addition, hot melt adhesives include fillers, softeners, plasticizers, colorants, antiblocking agents, antioxidants, UV absorbers, silane coupling agents, thixotropic agents, foaming agents, etc. Can be contained.

The softening point of the tackifying resin used is preferably 80 to 160 ° C. By setting the softening point to 80 ° C. or higher, the heat resistance can be kept good. On the other hand, by setting the softening point to 160 ° C. or lower, it is possible to improve the tackiness in a low-temperature atmosphere and to maintain good adhesion. In the present invention, 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 tackifier is 90 to 140 ° C from the viewpoint of balancing adhesiveness, heat resistance, and cold resistance, and a more preferable range is 100 to 130 ° C.

By using the wax, the viscosity of the hot melt adhesive can be lowered and coating can be facilitated.
The softening point of the wax used is preferably 70 to 120 ° C. When the softening point is 70 ° C. or higher, there is no possibility that the wax melts at a high temperature and the adhesive strength is reduced. On the other hand, when the softening point is 120 ° C. or lower, the temperature at which the hot melt is melted by heating is lowered, so that the coating property of the hot melt can be ensured. In the present invention, 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 of the present invention is 90 to 140 ° C, and a more preferable range is 100 to 130 ° C.

  The article 20 is not particularly limited as long as it is suitable for packaging with the heat-shrinkable film 11. For example, cosmetics, medicines, foods, batteries, toys, clothing, stationery items, miscellaneous goods and the like can be exemplified. The number of articles 20 to be packaged may be singular or plural. Moreover, the purpose of packaging can be used for various purposes such as transportation packaging as well as a mode of displaying products as a storefront.

  In Step 1 of the first embodiment, as shown in FIGS. 2A to 2C, the article 20 is packaged with a film 10 that can be heat-shrinked, and a film-packaging article 21 that is packaged with a heat-shrinkable film 11 is obtained. More specifically, the article 20 is inserted into the cylindrical heat-shrinkable film 10 (see FIG. 2A), and then the heat-shrinkable film is heated to shrink the heat-shrinkable film and the article 20 The film 11 that has been heat-shrinked is fitted (adhered) (see FIG. 2B). A conventionally used method can be arbitrarily applied as the method for heating and shrinking the heat-shrinkable film 10. By these steps, the film packaging article 21 covered with the heat-shrinked film 11 is obtained. The film 10 that can be heat-shrinkable may be individually cut in advance, or the heat-shrinkable film 10 wound up in a roll shape may be cut immediately before heat shrinkage.

  The heat-shrinkable film 10 is prepared with a desired size and shape by printing, forming perforations 15, slits, signatures, opening 16 and the like as necessary. Moreover, the film 10 which can be thermally contracted is selected so that the contraction rate differs depending on the direction, if necessary. Note that the example of FIG. 2A and the like is an example, and various modifications are possible. For example, the sheet-like heat-shrinkable film 10 may be wound around the article 20 and the overlapping portions may be joined with an adhesive. Alternatively, the sheet-like heat-shrinkable film 10 may be used as it is without using an adhesive, or the string-like heat-shrinkable film 10 may be wound around the article 20. As a method of using the sheet-like heat-shrinkable film 10 as it is, for example, the side periphery (body part) of the article 20 is wound one or more times with the film 10 that can be heat-shrinked, heated quickly, and the film 10 that can be heat-shrinked. Can be exemplified by a method in which the film 11 subjected to heat shrinkage is fitted (adhered) to the article 20. The same method can be illustrated also in the case of the film | membrane 10 which can carry out the heat shrink of the string shape.

  The film wrapping article 21 may be manufactured in the process of manufacturing the package 1 with the mount, or may be packaged at the same time as the product is completed in a factory or the like that manufactures the article 20. It may be packaged at the same time as the product is completed so that the article is properly protected during transportation and storage.

  In step 2 of the first embodiment, an example in which the adhesive layer 13 is formed on the mount 12 will be described. The mount 12 forms printing, decoration, hanging holes 14 and the like as necessary. On the mount 12 side, a perforation for facilitating taking out the article 20, a cut for opening, or the like may be provided. The mount 12 may be cut in advance for each product, or may be cut before and after applying the adhesive. Further, it is possible to separate the mount 12 at the final stage after the film packaging article 21 is attached. From the viewpoint of increasing the efficiency of the manufacturing process, a method of winding the mount 12 in a roll shape and cutting in the process of manufacturing the package 1 with the mount can be exemplified.

  As described above, the adhesive layer 13 is composed of a hot melt adhesive layer capable of reversibly repeating melting and solidification by heat. The hot melt adhesive to be used is not a so-called reactive hot melt adhesive, but may be a hot melt adhesive layer capable of reversibly repeating melting and solidification by heat. The adhesive layer 13 is obtained by applying a molten hot melt adhesive to a predetermined position of the mount 12.

  The melt viscosity of the hot melt adhesive is preferably included in the range of 1,000 to 50,000 mPa · s or less, more preferably in the range of 5,000 to 20,000 mPa · s, and particularly preferably The range is from 5,000 to 15,000 mPa · s. After forming the hot melt adhesive, it is usually returned to room temperature. Thereby, an adhesive agent solidifies. The melt viscosity refers to a value measured in a state substantially free of bubbles. Specifically, it refers to a value measured in a state where processing such as foaming is not performed, and bubbles contained in a very small amount are in a state not containing bubbles. Moreover, when air bubbles are mixed in during the manufacturing process, it means a value measured by performing a defoaming process.

  In step 3 of the first embodiment, the film wrapping article 21 wrapped with the heat-shrinked film 11 and the mount 12 are bonded together with the adhesive layer 13 interposed. The melted adhesive layer 13 is brought into contact with the part to be joined (the heat-shrinked film 11 of the mount 12 and the film packaging article 21), and then the adhesive layer 13 is solidified. Therefore, from the viewpoint of productivity, the step of forming the adhesive layer 13 in Step 2 and the step of joining the film packaging article 21 and the mount 12 in Step 3 are continued while maintaining the molten state of the adhesive layer 13. It is preferable to carry out. As a preferable example, for example, an adhesive 21 in a molten state is applied to a predetermined position of the mount 12 to form an adhesive layer 13 in a molten state, and an article 21 wrapped in a film that is quickly heat-shrinked while maintaining this state. An example is a method in which the adhesive layer 13 is solidified by natural cooling and then bonded together after contact.

  The method for joining the film packaging article 21 and the mount 12 is not limited to the above method, and various modifications are possible. For example, after a hot melt adhesive in a molten state is applied to a predetermined position of the mount 12, the adhesive layer 13 is cooled at one end, and when the film packaging article 21 and the mount 12 are attached, the adhesive layer is again used. The film packaging article 21 can also be bonded to the molten adhesive layer 13 by heating 13. According to this method, it becomes possible to perform each manufacturing process of the mount 12 with the adhesive layer 13, the film packaging article 21, and the package 1 with the mount at different timings and places. Heating for melting the adhesive layer 13 for bonding the film packaging article 21 and the mount 12 may be performed from the surface of the adhesive layer 13 or from the back side or the side of the mount 12. For example, the adhesive layer 13 can be melted from the back side of the mount 12 with hot air, and the film packaging article 21 and the mount 12 can be joined. Moreover, you may heat using a lamp | ramp etc. Further, when the mount 12 is plastic, it can be performed with steam.

  According to the conventional film package with a mount, packaging is completed by first preparing a mount with a film that can be heat-shrinked, inserting an article into the film, and shrinking the heat-shrinkable film by heating. According to this method, when an article is displaced from a desired position after the article is inserted into the mount with film that can be thermally shrunk until the film is shrunk, or while the film is shrunk. was there. In particular, when an article having an unbalanced shape, an article that is easy to move, or a plurality of articles are desired to be packaged, there is a possibility that the position of the article may be displaced, and the articles to be shrink-wrapped are limited. Moreover, even if the article is a target for shrink film packaging by a conventional method, the front position of the article may be shifted or the position of the article may be inclined, resulting in a packaging failure. In addition, according to the conventional method of inserting and packaging an article on a film-backed mount that can be thermally shrunk, there is a problem that the yield is poor in the manufacturing process.

  On the other hand, according to the manufacturing method of the packaging body with the mount according to the first embodiment, the film packaging article 21 is formed first, and the method of adhering the film packaging article 21 to the mount 12 is adopted. The problem of misalignment does not occur in relation to the mount. According to the method for manufacturing a package with a mount according to the first embodiment, particularly when it is difficult to apply to a conventional shrink film packaging, an unbalanced shape article, a movable article, or a plurality of articles is desired to be packaged. The present invention can also be suitably applied. In addition, since the film packaging article is prepared in advance, compared with the case where the article is put in the shrink film packaging body with mount and packaged, the positional deviation during the manufacturing process is prevented, and the production yield of the packaging body with mount is reduced. Can be increased.

  In addition, in recent years, reactive hot melt adhesives that have been actively developed are bonded to a film that can be thermally shrunk through an adhesive and a backing sheet, and then the time for moisture curing and UV A curing process is required. For this reason, processing facilities and management were necessary. By these curing treatments, it is possible to imagine the advantage of increasing the heat resistance by increasing the curability of the adhesive layer. However, there is a problem that the elastic force of the adhesive layer is lowered and the followability is lowered because the heat resistance by curing is improved. In particular, it was a problem at low temperatures.

  Since the non-reactive hot melt adhesive is used according to the method for manufacturing a package with a mount of the first embodiment, the bonding portion (the mount 12 and the heat-shrinked film 11) of the adhesive layer 13 is used. Bonding can be completed without post-processing steps. As a result, the film wrapping article 21 in which the article is packaged can be manufactured first, and then the heat-shrinked film 11 and the mount 12 of the film wrapping article 21 can be joined via the adhesive layer 13. Therefore, there is an advantage that the article and the film that can be thermally contracted do not need to have UV transparency and moisture resistance.

[Second Embodiment]
Next, an example of the manufacturing method of the packaging body with a mount different from the said embodiment is demonstrated. The manufacturing method of the packaging body with a mount according to the second embodiment is the same as the first embodiment except for the following points. That is, in the second embodiment, the adhesive layer 13 is formed on the film wrapping article 21, and the adhesive layer 13 is formed on the mount 12 at a point where the adhesive layer 13 is bonded to the mount 12. This is different from the manufacturing method of the first embodiment to be bonded.

  According to the method for manufacturing a package with a mount according to the second embodiment, after obtaining the film packaging article 21 packaged with the heat-shrinkable film 11 as shown in FIG. A molten adhesive layer 13 is provided and bonded to the mount 12.

  According to the method of the second embodiment, the same effect as in the first embodiment can be obtained. In addition, since the adhesive layer 13 is formed on the film packaging article 21, it is possible to more reliably prevent the position of the adhesive layer 13 and the joining position from being shifted when the film packaging article 21 and the mount 12 are joined. Considering the thermal influence on the heat-shrinkable film 11 and the article 20, it is preferable to form the molten adhesive layer 13 on the mount 12 side as shown in FIG. 2C. However, for example, as shown in FIG. 4A and FIG. 4B, it is useful in the case where the article is likely to be poorly connected due to a slight positional deviation, such as when the article is narrow, such as a toothbrush. Further, it is also suitable when it is desired to join a plurality of film packaging articles 21 on a single mount or when an article having a large uneven shape, an article having a complicated shape having a through hole, an opening, or the like is to be packaged.

[Third Embodiment]
The manufacturing method of the packaging body with mount according to the third embodiment is the same as the first embodiment except for the following points. That is, the third embodiment is different from the manufacturing method of the first embodiment in which a tubular heat-shrinkable film 10 is used in that a sheet-like heat-shrinkable film is used.

  The packaging body with the mount of the third embodiment is formed of a film 10a that can be thermally contracted by cutting the film 10a that is heat-shrinkable on a roll as shown in FIG. 5A into a desired size to cover the article 20. The overlapping part between the films at the winding end part is joined with an adhesive or the like. Thereafter, the film 10a that can be thermally contracted by heating is contracted to obtain a film packaged article in which the article is packaged. Subsequently, in the same manner as in the first embodiment, a molten adhesive layer is provided at a predetermined position of the film packaged article, and this is joined to the mount to obtain a package with a mount. In addition, the cut timing of the film 10a that can be thermally contracted may be before the article 20 is coated, before the thermal contraction after coating, or after the film packaging article after the thermal contraction is formed.

  The sheet-like heat-shrinkable film is an example, and various modifications are possible. For example, as shown in FIG. 5B, an article (not shown) is sandwiched between two sheets of heat-shrinkable film 10b, the overlapping portions of the films are joined with an adhesive or the like, and heat-shrinked by heating. By shrinking the obtained film 10b, a film packaged article in which the article is packaged may be obtained.

  According to the conventional method for producing a heat-shrinkable film mount first, it cannot be said that the degree of freedom of the form of the heat-shrinkable film is high. On the other hand, according to the method for manufacturing a package with a mount of the present invention, since the film that can be thermally shrunk on the article is first coated and packaged, it is possible to increase the degree of freedom of the form of the heat shrunk film. Become. For example, a film that can be heat-shrinkable may be a string-like film, or a film that is optimally cut along the shape of the article. Therefore, according to the manufacturing method of the packaging body with a mount of the present invention, the packaging target article can be expanded as compared with the conventional method of producing the backing with a film that can be thermally contracted first.

[Fourth Embodiment]
As for the manufacturing method of the packaging body with mount which concerns on 4th Embodiment, the basic manufacturing method except the following points is the same as that of 1st Embodiment. That is, in the fourth embodiment, in order to reduce thermal damage to the article at the position of the heat-shrinked film on which the adhesive layer 13 is provided, the overlapping portion of the heat-shrinkable film is provided. This is different from the manufacturing method of the first embodiment in which no part is provided.

  According to the manufacturing method of the packaging body with mount based on 4th Embodiment, as shown in FIG. 6, the overlapping part 25 of films is provided in the heat-shrinked film 11 joined to the adhesive bond layer 13. As shown in FIG. For this reason, the heat given to articles | goods can be reduced at the time of formation of the adhesive bond layer 13 which consists of a hot-melt-adhesive adhesive layer. The overlapping portion 25 can be joined with an adhesive or the like. Further, a sheet having a higher heat insulating property and / or higher heat dissipation property may be laminated on the overlapping portion 25, or an adhesive having a higher heat insulating property and / or higher heat dissipation property may be used. Note that the overlapping portion 25 in FIG. 6 is an example, and it goes without saying that various modifications are possible.
