Description

  The present invention relates to a synthetic resin round sheet.

  A round sheet is a sheet on which a pattern is printed, and is a type of a sales promotion tool used in stores that sell goods. By covering the lower part of the corrugated cardboard and the wagon arranged in the store, the round seat can produce the atmosphere in the store or make the displayed items stand out. For example, a round sheet may be used to hide the design and color of the surface of the cardboard 1 on which the product 2 as shown in FIG. 8 is displayed.

  The round sheet is also called a curtain, and for example, it is made of synthetic resin, paper, cloth or the like. When the round sheet is made of a synthetic resin, the round sheet is manufactured and sold by being wound into a roll in units of, for example, a height of 60 cm and a length of 10 m. And a round sheet is installed in a store, after being cut | disconnected to required length according to the place used.

  By the way, the synthetic resin round sheet is superior in water resistance as compared with paper, and is suitable for use in a supermarket that handles fresh vegetables and the like. As shown in FIG. 6, a conventional synthetic resin round sheet 10 is generally provided with a design printing layer 14 on one surface side of a transparent film layer 12 made of synthetic resin. However, even if such a conventional round sheet 10 is used to cover the cardboard 1 shown in FIG. 8, there is a problem that the design and color of the surface of the cardboard 1 are transparent as shown in FIG. May occur.

  In order to solve this problem, as shown in FIG. 7, a round sheet 20 in which a design print layer 24 is provided on one side of a transparent film layer 22 and then a white print layer 26 is provided on the design print layer 24 is used. It is possible to do. However, even if the white print layer 26 is further added, the design and color of the surface of the cardboard 1 may still be seen by the inventor of the present invention as shown in FIG. The problem of not being able to be solved became clear.

  Therefore, the present invention has been made in view of the above problems, and the object of the present invention is to prevent the transmission of the design and color of the article installed on the back side by being installed on the article. On the other hand, it is an object of the present invention to provide a new and improved synthetic resin round sheet capable of improving the design printed on the surface and preventing the design from being damaged.

  In order to solve the above problems, according to a certain aspect of the present invention, a transparent film layer made of a synthetic resin having a pattern printing layer made of ink provided on one side, and a pattern of the transparent film layer via an adhesive layer A synthetic resin round sheet is provided that includes an opaque synthetic resin white film layer laminated with a transparent film layer, which is bonded to a surface provided with a printing layer.

  The transparent film layer makes the design of the design printed layer look good and prevents the design from being damaged, and the white film layer prevents the design and color of the article placed on the back side from being transmitted.

  As described above, according to the present invention, by being installed in an article, it is possible to improve the appearance of the design printed on the front surface while preventing the transmission of the design and color of the article installed on the back side. Can be prevented.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in this specification and drawing, about the component which has the substantially same function structure, the duplicate description is abbreviate | omitted by attaching | subjecting the same code | symbol.

First, the configuration of the round sheet 100 according to an embodiment of the present invention will be described.
The round sheet 100 includes a transparent film layer 102, a design printing layer 104, a white film layer 106, and an adhesive layer 108. By forming the design print layer 104, the design and color that can be seen on the surface of the round sheet 100 are determined. The round sheet 104 is displayed at a store or the like, and can take various designs and colors according to the product to be sold, the atmosphere of the store, and the like. The round sheet 100 is manufactured and sold by being wound in a roll shape, for example, in units of 60 cm in height and 10 m in length. And the round sheet 100 is installed in a shop after being cut | disconnected by length required according to the place used.

  The transparent film layer 102 is a transparent synthetic resin film. The transparent film layer 102 is a stretched film made of a polypropylene resin and stretched in the biaxial direction, for example, a biaxially stretched polypropylene film. The transparent film layer 102 has a thickness of 20 μm, for example. On one side of the transparent film layer 102, a design print layer 104 is provided. The transparent film layer 102 is not limited to the biaxially stretched polypropylene film described above. For example, in the case of polypropylene (PP), non-stretching or uniaxial stretching may be used. However, the biaxial stretching is more suitable for manufacturing the round sheet 100 because it is less likely to expand and contract during the printing process and the laminating process as compared with non-stretching or uniaxial stretching. Further, for example, polyethylene (PE) or polyethylene terephthalate (PET) may be used. However, polypropylene is more transparent than polyethylene and the material is more difficult to expand and contract, so that printing displacement is less likely to occur, and curling during lamination is also loosened. Polyethylene terephthalate has a high transparency of the material and tends to hardly expand or contract, but polypropylene is cheaper.

  The design print layer 104 is made of ink composed of a pigment, a solvent, and the like, and is formed by printing on one surface side of the transparent film layer 102 by a printing method such as gravure printing or offset printing. A general technique can be applied to the printing method, and detailed description thereof is omitted in this specification.

  The white film layer 106 is an opaque milky white or white synthetic resin film. The white film layer 106 is a stretched film made of a polypropylene resin and stretched in a biaxial direction, for example, a biaxially stretched polypropylene film. The white film layer 106 has a thickness of 30 μm, for example. An adhesive layer 108 is provided on one surface side of the white film layer 106. The white film layer 106 is bonded to the surface of the transparent film layer 102 on which the design print layer 104 is provided via the adhesive layer 108, and is laminated with the transparent film layer 102. The white film layer 106 is not limited to the biaxially stretched polypropylene film described above. For example, as in the case of the transparent film layer 102, polypropylene such as non-stretched or uniaxial stretch may be used, and polyethylene (PE) or polyethylene terephthalate (PET) may be used.

  Since the white film layer 106 is opaque, the combination of the white film layer 106 and the design print layer 104 can prevent transmission of the design and color of the article on the back side. By selecting the color intensity of the white film layer 106, the degree of transmission of the design and color of the article on the back side can be adjusted.

  The adhesive layer 108 is made of, for example, a polyurethane-based adhesive, and the white film layer 108 is bonded to the surface of the transparent film layer 102 on which the design print layer 104 is formed by a bonding method such as dry lamination. It is formed. A general technique can be applied to the bonding method. The polyurethane-based adhesive may be either ester-based or ether-based. Note that, as a bonding method other than dry lamination, there are wet lamination to be bonded before the adhesive is dried, sand poly sandwiched with polyethylene, and the like. Dry lamination is more suitable for the round sheet 100.

Next, the manufacturing method of the round sheet 100 which concerns on one Embodiment of this invention is demonstrated.
First, a design is printed on one side of the transparent film layer 102 by a gravure printing method or the like. As a result, as shown in FIG. 2, the design print layer 104 is formed on one surface side of the transparent film layer 102.

  Then, the transparent film layer 102 provided with the design print layer 104 and the white film layer 106 are bonded together. First, an adhesive is applied to one side of the white film layer 106. As a result, as shown in FIG. 3, an adhesive layer 108 is formed on one side of the white film layer 106. Thereafter, as shown in FIG. 4, the surface of the transparent film layer 102 on which the design print layer 104 is provided and the surface of the white film layer 106 on which the adhesive layer 108 is provided face each other. Bond the two sheets of film together.

  By the above procedure, a round sheet 100 according to the present embodiment which is long and sheet-like and has a cross section as shown in FIG. 1 is manufactured.

  Next, the process of the dry lamination method in the manufacturing method of the round sheet 100 concerning this embodiment is demonstrated in detail.

  The dry lamination method consists of (1) feeding the white film layer 106 → (2) applying the adhesive → (3) drying → (4) feeding the transparent film layer 102 on which the design print layer 104 is formed → (5) laminating → (6) It consists of a process of winding the round sheet 100 as a final product.

  When two films are bonded together, the tension applied to the films is set according to the thickness and Young's modulus of these films. Due to this subtle difference in tension, the bonded sheets are generally curled in either the front or back direction. If the curl is too strong, the round sheet 100 according to the present embodiment may hinder the work in the winding process or the cutting process, which is the next process of the laminating process for bonding the two films. That is, the round sheet 100 as a final product that is distributed and sold has a shorter length per unit than a general sheet product, and is a small roll of about 10 m, for example. When making a small roll, a sheet with strong curl tends to cause problems in winding and cutting. Therefore, it is desirable to eliminate the curl. In addition, the round sheet 100 having a strong curl causes a phenomenon such as peeling off or curling of a corner due to the stress of the curl when the round sheet 100 is fastened to a corrugated cardboard or a wagon at the time of use in a store.

  Therefore, the round sheet 100 according to the present embodiment is suitable to have a film that has less residual stress than usual and is finished in a flat state (light inner curl at least) as much as possible. Here, the inner curl means that the round sheet 100 is curled on the white film layer 106 side.

  In order to manufacture the round sheet 100 suitable for use as described above, it is required to bond in a low tension state in the bonding step. Therefore, since the white film layer 106 is heated by the drying step (3) and a strong stress is generated in the white film layer 106 due to thermal contraction after cooling, the tension of the white film layer 106 is not meandered before bonding. Keep to low tension. Then, the transparent film layer 102 on which the design print layer 104 is formed is bonded to the low tension white film layer 106. As a result, the round sheet 100 with extremely small residual stress can be finished.

  In addition, when the final product is not a sheet shape like the round sheet 100 of the present embodiment but is a processed product (for example, a synthetic resin product such as a plastic bag), in the process leading to the final product, as in the present embodiment. There is no small roll. Therefore, the problem of eliminating curl when making a small roll is not a general problem and is specific to the present embodiment, and the above-described bonding process is also a process specific to manufacturing the round sheet 100 of the present embodiment. It is.

  As described above, according to the round sheet 100 of the present embodiment, the white film layer 106 is provided on one side of the design print layer 104, and the transparent film layer 102 is provided on the other side of the design print layer 104. As a result, by installing the round sheet 100 on an article such as cardboard or a wagon, it is possible to improve the appearance of the design printed on the surface with gloss while preventing the transmission of the design and color of the article on the back side. it can. Further, even if there is a contact from the outside of the round sheet 100, the pattern of the round sheet 100 is not rubbed or scraped.

  The round sheet is a kind of sales promotion tool, has a life cycle according to the season and the target product, and is required to suppress the manufacturing cost. In order to control the manufacturing cost, it is common to think about how to reduce the cost in the range of products that are finished with a conventional round sheet configuration, that is, a pattern printed on one film. Is. Therefore, unlike the present embodiment, the configuration of the round sheet 100 in which two films are bonded together is not devised in the field of normal round sheets. In addition, the problem that the design and color of the article on the back of the round sheet is transparent is a problem that was first studied in earnest by the inventor, and has not been suggested in the field of conventional round sheets. There is no new challenge. Therefore, it is difficult to conceive the round sheet 100 of the present embodiment based on the conventional round sheet.

  Furthermore, the inventor not only solves the problem of preventing the see-through and color of the article behind the round sheet, but also improves the appearance of the design of the round sheet itself and prevents external damage. We also focused on the task of doing. In order to solve the problem of see-through, in the round sheet 10 as shown in FIG. 6, a white film layer 12 is provided instead of the transparent film layer 12, and the design printing layer 14 is placed on the surface. When used, it is possible to suppress the transparency of the pattern and color on the surface of the cardboard 1. However, since the design print layer 14 is on the surface, there is a problem that even if glossy ink is used, the design is not glossy and inferior to the case where the design is shown through the transparent film layer. Further, when a person or an object comes into contact with the round sheet 10, the design print layer 14 is rubbed or the design print layer 14 is scraped off. In order to solve this problem, the round sheet of this embodiment is not devised in an attempt to achieve the demand for cost reduction as described above. As shown in FIG. After the design print layer 24 is provided on the one surface side, the white print layer 26 is provided on the design print layer 24. However, the configuration of the round sheet 20 shown in FIG. 7 cannot completely solve the problem of see-through. On the other hand, according to the present embodiment, the problem of improving the appearance can be solved, and the problem of preventing the pattern and color of the article on the back side of the round sheet as described above can also be solved.

  As mentioned above, although preferred embodiment of this invention was described in detail, referring an accompanying drawing, this invention is not limited to this example. It is obvious that those who have ordinary knowledge in the technical field to which the present invention belongs can conceive various changes or modifications within the scope of the technical idea described in the claims of the utility model registration. These are naturally understood to belong to the technical scope of the present invention.

  For example, in the above embodiment, when the transparent film layer 102 provided with the design print layer 104 and the white film layer 106 are bonded together, the adhesive is applied to one surface side of the white film layer 106. It is not limited to. For example, the adhesive layer 108 may be formed by applying an adhesive to the surface of the transparent film layer 102 on which the design print layer 104 is provided, that is, the design print layer 104. Then, the surface of the transparent film layer 102 on which the design print layer 104 and the adhesive layer 108 are provided and the white film layer 106 face each other, and two films may be bonded together by a dry lamination method or the like. Also by this procedure, a round sheet similar to the round sheet 100 described in the above embodiment is obtained.
