Description

  The present invention relates to a printing film and a film package.

  For example, there is a package that accommodates an object to be accommodated such as a cigarette whose outer side is packaged with a film. In addition, information relating to an object to be stored, such as a temporary campaign notice, may be printed on the film. Conventionally, when printing is performed on a transparent film of a package, the entire printed part is coated with white ink from the back to protect the printed part. Further, when the printing portion is coated with white ink, there is a restriction that the printed content must be a design based on white.

  Conventionally, a technique of applying an overprint varnish to a printed matter printed on a plastic film has been proposed (Patent Document 1). In addition, techniques for performing printing or the like so as to further cover the printing layer of the printing film have been proposed (Patent Documents 2 and 3).

  Even when a transparent varnish (also simply referred to as “varnish”) is used, a boundary between a portion coated with the varnish and a portion not coated may appear. And if the boundary becomes conspicuous, the design will not be intended by the designer, or the user will feel uncomfortable. Then, an object of this invention is to provide the printing film which made the coating for protecting a printing part (especially the outline of the coated part) inconspicuous.

  In order to solve the above-mentioned problems, a printing film according to the present invention includes a printing part in which a predetermined display is formed with ink on a part of a transparent film, a coating part that covers the printing part with varnish, and a plane of the film. Visually, it is provided around the coating part, and has a gradation part covered with varnish so that the amount of varnish decreases stepwise as the distance from the coating part increases.

  In this way, since the amount of varnish gradually decreases from the portion covered with the varnish toward the periphery thereof, the change can be blurred. That is, the coating for protecting the printing portion can be made inconspicuous.

  Moreover, you may make it the area of the part covered with the varnish decrease, so that the gradation part of a printing film leaves | separates from the coating part. Here, the area of the portion covered with varnish is the area of the portion covered with varnish per predetermined unit area. Specifically, by doing so, the coating for protecting the printing portion can be made inconspicuous.

  Furthermore, in the gradation part, a plurality of rows of dots formed by the varnish are arranged substantially parallel to the contour of the coating portion, and the number of dots per row decreases as the distance from the coating portion increases. Also good. Specifically, the gradation part can be realized by such an aspect.

  Further, the gradation portion may have a smaller dot size as the distance from the coating portion increases. Further, the gradation portion may be arranged such that the interval between the rows becomes wider as the distance from the coating portion increases. Further, the gradation portion may have a thinner varnish as the distance from the coating portion increases. A gradation part can be realized also by such a mode.

  According to another aspect of the present invention, it is also possible to provide a film package including a package that accommodates tobacco products and a printed film that wraps the package. Here, the printing film is provided around the coating portion in plan view of the film, a printing portion in which a predetermined display is formed with ink on a part of a transparent film, a coating portion that covers the printing portion with varnish, and a plan view of the film And a gradation portion covered with varnish so that the amount of varnish decreases stepwise as the distance from the coating portion increases. If the printing film which concerns on this invention is used, the coating for protecting a printing part can be made not conspicuous. Therefore, if it is a film package as mentioned above, the freedom degree of design of a printing film and a package will improve.

  Examples of cigarette products include cigarettes (filter cigarettes, double-cut cigarettes (no filter)), cigars (cigars), cigarillos, snus, snuff, chewing tobacco, and electronic cigarettes.

  Further, means for solving the problems in the present invention can be employed in combination as much as possible.

  Next, an embodiment of a film and a film package according to the present invention will be described based on the drawings. The application of the film according to the present invention is not particularly limited, but here, an example of packaging tobacco products will be described.

<Structure of film package>
A configuration of a film package (also simply referred to as “package”) 1 including a package 11 and a film 12 that packages the package 11 will be described with reference to FIG. FIG. 1 is a perspective view of a package 1 before opening according to an embodiment.

  The package 11 included in the package 1 may be a hinge lid type package as illustrated, or may be another hard package or a soft package. The package 11 includes a cigarette bundle (not shown) wrapped with, for example, aluminum vapor-deposited paper.

  The film 12 is a transparent (colorless and transparent) polymer film, for example, and is made of a material such as polypropylene (PP), polyethylene (PE), cellophane, or the like. The film 12 has a print area 121 at least in part. The print area 121 is provided, for example, on the back surface of the film 12 (that is, the inner surface of the package 1 and the surface in contact with the package 11). The film 12 may be a translucent or colored transparent film. Moreover, the film 12 having the print region 121 is also referred to as a print film according to the present invention.

  The film 12 also has an opening tape (also referred to as “tea tape”) 122. The opening tape 122 is a belt-like member wound around the surface of the package 11 and is attached to the back surface of the film 12 (that is, the inner surface of the package 1 and the surface in contact with the package 11). It has been. The film 12 is provided with a cut so that one end 1221 of the opening tape 122 can be gripped, and the user can tear the film 12 to open the package 1 by pulling the one end 1221. Yes.

<Composition of printing film>
FIG. 2 is a diagram for explaining the print area 121. FIG. 2 is a plan view of the print area 121 provided in a part of the film 12 from the surface side of the film 12 (that is, the outside of the package 1). The printing area 121 includes a printing unit 1211 printed with colored ink, a coating unit 1212 that is coated with a varnish (also simply referred to as “varnish”) to cover the entire printing unit 1211, and protects the printing unit 1211. Visually, a gradation portion 1213 provided around the coating portion 1212 is included.

  The printing applied to the printing unit 1211 can be performed using various methods that can be printed on a film, such as gravure printing or UV (Ultraviolet) printing. It is assumed that the printing unit 1211 includes an area filled with black and an area hatched with diagonal lines and is printed in different colors. The coating portion 1212 and the gradation portion 1213 can be formed by printing using varnish instead of ink.

  The varnish according to the present embodiment is a transparent paint containing no pigment, and is formed, for example, by dissolving a resin in a solvent. The ink is a colored paint containing a pigment, and is formed, for example, by mixing a pigment with a varnish. In this embodiment, existing varnish and ink can be used.

  The coating unit 1212 is provided to “press” the printing unit 1211. That is, by covering the printing unit 1211 with the varnish, it is possible to improve slipping and improve wear resistance. For example, it is possible to prevent the printing from being rubbed off. Further, the anti-blocking performance can be improved by the coating portion 1212. That is, the films 12 and the film 12 and the package 11 are prevented from sticking to each other.

  The gradation part 1213 is provided around the printing part 1211, and the amount of varnish decreases stepwise as the distance from the printing part 1211 and the coating part 1212 increases. FIG. 3 is an enlarged view of the periphery of the print area 121. Further, the gradation portion 1213 in FIG. 3 is indicated by a line parallel to the outlines of the printing portion 1211 and the coating portion, and schematically represents the amount of varnish by the thickness of the line and the interval between the lines. As shown in FIG. 3, the gradation portion 1213 has a larger amount of varnish as it is closer to the printing portion 1211 and the coating portion 1212, and a smaller amount of varnish as it is farther from the printing portion 1211 and the coating portion 1212.

<Configuration 1 of gradation part>
FIG. 4 shows an example of the configuration of the gradation unit 1213. FIG. 4 is an enlarged view of the printing area 121 provided in a part of the film 12 as viewed from the front side of the film 12. On the film 12, a coating part 1212 having a size larger than the area of the printing part 1211 is formed so as to cover the printing part 1211. A gradation portion 1213 is provided around the coating portion 1212. In the gradation portion 1213, dots (also referred to as “small areas”) formed of varnish are arranged in a row. For convenience, FIG. 4 shows broken lines representing columns. The dot rows are arranged substantially parallel to the contour of the coating portion 1212. In the example of FIG. 4, the dot row is substantially parallel to the outline of the printing unit 1211. In the example of FIG. 4, the number of dots per row decreases as the distance from the coating portion 1212 increases (that is, the distance from the printing portion 1211 increases).

  In the example of FIG. 4, a row of dots substantially parallel to the contour of the coating portion 1212 is shown, but the dots do not have to be aligned in parallel. For example, the dots may be arranged in a random or predetermined pattern so that the number of dots per predetermined unit area decreases as the distance from the coating unit 1212 increases. Here, the unit area refers to an area of an arbitrary shape that has a size that can be accommodated in the gradation portion 1213 and that includes a plurality of dots inside the shape. In other words, in the gradation part 1213, as the distance from the coating part 1212 increases, the area of the region covered with the varnish per predetermined unit area becomes smaller.

<Configuration of gradation part 2>
FIG. 5 shows another example of the gradation part 1213. FIG. 5 is also an enlarged view of the printing area 121 provided in a part of the film 12 as viewed from the surface side of the film 12. The gradation portion 1213 in FIG. 5 is also arranged so that the dots formed of varnish form a line substantially parallel to the contour of the coating portion 1212. In the example of FIG. 5, the size of each dot decreases as the distance from the coating portion 1212 increases.

  In the example of FIG. 5 as well, a row of dots substantially parallel to the contour of the coating portion 1212 is shown, but the dots do not have to be aligned in parallel. For example, the dots may be arranged randomly or in a predetermined pattern so that the size of the dots decreases as the distance from the coating unit 1212 increases. In other words, in the gradation part 1213, as the distance from the coating part 1212 increases, the area of the region covered with the varnish per predetermined unit area becomes smaller.

<Configuration 3 of gradation part>
FIG. 6 shows another example of the gradation part 1213. FIG. 6 is also an enlarged view of the printing area 121 provided in a part of the film 12 as viewed from the surface side of the film 12. The gradation portion 1213 in FIG. 6 is also arranged so that the dots formed of varnish form a line substantially parallel to the contour of the coating portion 1212. In the example of FIG. 6, the distance from the adjacent row increases as the distance from the coating portion 1212 increases.

  Also in the example of FIG. 6, a row of dots that is substantially parallel to the contour of the coating portion 1212 is shown, but the dots may not be aligned in parallel. For example, the dots may be arranged in a random or predetermined pattern so that the distance between the dots included in the predetermined unit area increases as the distance from the coating portion 1212 increases. In other words, in the gradation part 1213, as the distance from the coating part 1212 increases, the area of the region covered with the varnish per predetermined unit area becomes smaller.

<Configuration 4 of gradation part>
FIG. 7 shows another example of the gradation part 1213. FIG. 7 is an AA cross-sectional view of the film 12 shown in FIG. Further, as shown in FIG. 7, the printing unit 1211, the coating unit 1212, and the gradation unit 1213 are provided on the back side of the film 12. In addition, the back side of the film 12 is a side in contact with the package 11 of the package 1. In the gradation portion of FIG. 7, the varnish thickness decreases as the distance from the coating portion 1212 increases. In other words, in the gradation portion 1213, the amount of varnish per predetermined unit area decreases as the distance from the coating portion 1212 increases. Such printing is realized by, for example, gravure printing (that is, intaglio printing). The varnish thickness is not limited to a linear change in cross-sectional view. For example, a row substantially parallel to the contour of the coating portion 1212 is provided, and the varnish thickness decreases stepwise as the distance from the coating portion 1212 increases. May be.

  When the above-described configurations 1 to 4 are summarized, the gradation portion 1213 has a smaller amount of varnish as the distance from the coating portion 1212 increases. Further, when the above configurations 1 to 3 are summarized, the gradation portion 1213 has a smaller area covered with varnish per predetermined unit area as the distance from the coating portion 1212 increases.

  The configuration of the gradation unit 1213 may be a combination of the configurations shown in the above configurations 1 to 4. In particular, the gradation portion 1213 is configured such that dots formed of varnish are arranged in a row substantially parallel to the contour of the coating portion 1212, and the thickness of the varnish decreases as the row is further from the coating portion 1212. By doing so, the coating can be made inconspicuous more naturally. Further, the gradation part 1213 arranges the dots formed of the varnish so as to form a line substantially parallel to the outline of the coating part 1212, and the number of dots per line decreases as the distance from the coating part 1212 increases, and You may form so that the magnitude | size of each dot may become small. Furthermore, the thickness of the varnish may be reduced as the line is further from the coating part 1212. Further, other combinations may be adopted, or three or more configurations may be combined.

  In the configurations of FIGS. 4 to 6, rounded square dots are shown, but the shape of the dots is not limited to this. The dot can adopt various shapes such as a rectangle, other polygons, and an ellipse. 4 to 6 are exaggerated for convenience of explanation, the dots may be of a size that cannot be recognized with the naked eye. Further, the number of rows of dots indicated by broken lines in FIGS. 4 to 6 is five, but the number of rows is not limited to five.

  Further, the dot row of the gradation portion 1213 shown in FIGS. 3 to 6 is formed substantially parallel to the outlines of the printing portion 1211 and the coating portion 1212 in plan view, but is not limited to such an aspect. . FIG. 8 shows an example in which the outline of the printing unit 1211 has a complicated shape. In the example of FIG. 8, the contour of the gradation portion 1213 is not parallel to the contour of the printing portion 1211 and the contour of the coating portion 1212. In this case, for example, a plurality of shapes that interpolate between the contour of the coating portion 1212 and the contour of the gradation portion 1213 are defined, and the inside of each region is printed so that the amount of varnish decreases as the distance from the coating portion 1212 increases. Shall.

  According to the gradation part 1213 according to this embodiment, the amount of varnish gradually decreases from the coating part 1212 on the film 12 to the surrounding part not covered with the varnish, so that the outline of the coating part 1212 is conspicuous. Can not be. That is, according to the gradation part 1213, the boundary between the coating part 1212 and its surroundings can be harmonized naturally. In addition, since the periphery of the coating portion 1212 is not trimmed, the reproducibility of the intended design is improved. Further, by blurring the outline of the coating portion 1212, it becomes possible to express the cloudiness.

<Manufacturing method>
The manufacturing method of a printing film is demonstrated using FIG.9 and FIG.10. First, as shown in FIG. 9, a printing unit 1211 is formed on the film 12. Here, of the two surfaces of the film 12, the side on which printing is performed is also referred to as a printing surface. The printed surface is a surface that comes into contact with the package 11 in a state where the package 11 is packaged with the film 12 and is inside the package 1. Therefore, when viewed from the printing surface, the characters and graphics of the printing unit 1211 are reversed from the characters and graphics when the package 1 is viewed from the outside.

  Next, as shown in FIG. 10, a coating portion 1212 and a gradation portion 1213 are formed on the film 12. The coating part 1212 and the gradation part 1213 are also provided on the printing surface. In the present embodiment, the coating unit 1212 is provided so as to cover the entire printing unit 1211. In other words, the coating unit 1212 is printed with its position aligned on the printing unit 1211. The area of the coating part 1212 is larger than the area of the printing part 1211. A gradation portion 1213 is printed around the coating portion 1212. Note that the coating portion 1212 and the gradation portion 1213 can be printed together at the same time.

  With the procedure as described above, it is possible to print the coating portion 1212 for protecting the printing portion 1211 using ink and the gradation portion 1213 for naturally harmonizing the boundary between the coating portion 1212 and its surroundings.

  In addition, although the printing area | region 121 exists in the inner side of the package 1, it is reduced that a printing rubs and falls, The printing area | region 121 is provided in the outer side of the package 1 (namely, the surface of the film 12). Also good. In this case, characters and graphics in the printing unit 1211 are printed without being reversed left and right. When a translucent film or a colored transparent film is used as the film 12, when printing is performed on the surface of the package 12 on the package 11 side of the package 1, the color of the film 12 is displayed in the print region 121. It will overlap. If printing is performed on the surface of the film 12, the color of the film 12 does not overlap the print area 121, and a color faithful to the design can be reproduced.

<Comparative Example 1>
Next, the film 22 according to the comparative example will be described with reference to FIG. FIG. 11 is a view of the print region 221 provided in a part of the film 22 as viewed from the surface side of the film 22. The printing area 221 includes a printing unit 2211 printed with colored ink and a coating unit 2212 coated with white ink so as to cover the entire printing unit 2211. Even when the printing unit 2211 is covered with white ink, for example, the printing unit 2211 can be prevented from being rubbed off.

  However, in the case of Comparative Example 1, there is a design limitation that the background must be white. On the other hand, according to the embodiment of the present invention, the degree of freedom in design is increased by coating with a transparent varnish.

<Comparative example 2>
Next, the film 32 which concerns on a comparative example is demonstrated using FIG. FIG. 12 is also a view of the print region 321 provided in a part of the film 32 as viewed from the surface side of the film 32. The printing area 321 includes a printing unit 3211 printed with colored ink and a coating unit 3212 coated with a varnish so as to cover the entire printing unit 3211. However, the print area 321 does not have a gradation portion. Even when the printing unit 3211 is covered with a varnish, for example, the printing unit 3211 can be prevented from being rubbed off.

  In the case of Comparative Example 2, even if a transparent varnish is used, the contour of the portion coated with the varnish becomes conspicuous. That is, there is a difference in thickness between the varnish-coated portion and the uncoated portion of the film 32, and the material is also different in terms of the presence or absence of the varnish, so that the visible light transmittance is also different. Therefore, a boundary appears between the coating portion 3212 and the periphery thereof.

  On the other hand, according to the embodiment of the present invention, by providing the gradation portion 1213 around the coating portion 1212, the boundary between the coating portion 1212 and the periphery thereof can be blurred. Therefore, according to the embodiment of the present invention, it is possible to provide a print film in which the coating portion 1212 and its surroundings are naturally harmonized. In particular, the package 11 of such a product may have a restriction that a warning display must be put in a predetermined size, and the allowable range of design expressions tends to be narrow. When printing is also performed on the film 12 that wraps the package 11 so as to overlap the design of the package 11, the design of the package 11 and the design of the film 12 act synergistically by reducing the constraints on the design of the film 12. Design that makes it possible is also possible and useful.

  In the above-described example, cigarette products such as filter cigarettes and double-cut cigarettes are listed as objects to be accommodated in the package. However, the objects to be accommodated are not limited to these, and may be food, stationery, or the like.
