Description

Printed film and film packaging

This invention relates to printed films and film wraps.

For example, in a package for accommodating an object to be stored such as a cigarette, a package is attached to the outside with a film. Further, information on the contained object or other information such as a notification of a temporary activity may be printed on the film. Conventionally, when printing is applied to a transparent film of a package, in order to protect the printing portion, coating is applied to the entire printing portion by a white ink from the back surface. Further, when the printing portion is coated with white ink, there is a limitation that the printing content must be set to a white color.

Further, in the related art, a technique of applying an overprint varnish to a printed matter printed on a plastic film has been proposed (Patent Document 1). Further, a technique of applying printing or the like to cover the printed layer of the printing film again has been proposed (Patent Documents 2 and 3).

Even if a transparent varnish (also referred to as "varnish") is used, there is a case where a portion coated with the varnish is applied to the boundary between the uncoated portion. Also, when the border becomes conspicuous, it will form a design that does not meet the designer's expectations, or it will make the user feel uncoordinated. Accordingly, it is an object of the present invention to provide a printed film which is useful for protecting the coating of the printing portion (especially the contour of the portion to be coated) from being conspicuous.

In order to solve the above problems, the printing film of the present invention has a printing portion in which a predetermined display is formed by ink in a part of the transparent film, a coating portion covering the printing portion with a varnish, and a gradation portion in a plan view of the film. It is disposed around the coating portion and is covered by the varnish in such a manner that the amount of the varnish decreases stepwise as the distance from the coating portion decreases.

According to this, since the amount of the varnish gradually decreases from the portion covered with the varnish toward the periphery thereof, the change can be blurred. That is, the coating that can be used to protect the printing portion becomes unobtrusive.

Further, the gradation portion of the printed film may be made smaller as the distance from the coating portion becomes smaller, and the area of the portion covered with the varnish is reduced. Here, the area of the portion covered with the varnish means the area of the portion covered with the varnish per predetermined unit area. Specifically, by the above The type that can be used to protect the printing portion becomes unobtrusive.

Further, the gradation portion may be configured to arrange a plurality of dots of a dot formed by the varnish so as to be substantially parallel to the contour of the coating portion, and the farther away from the coating portion , the number of points in each row is reduced. Specifically, the gradation portion can be realized by such an aspect.

Further, the gradation portion may be set such that the further the distance from the coating portion, the smaller the size of the dots. Further, the gradation portion may be set to be wider as the distance from the coating portion is further increased. Further, the gradation portion may be set such that the further the distance from the coating portion is, the thinner the varnish is. In this way, the gradation can also be realized.

According to other aspects of the present invention, there is provided a film package comprising a package for containing a cigarette product, and a printed film for packaging the package. Here, the printing film has a printing portion in which a predetermined display is formed by ink in a part of the transparent film, and a coating portion that covers the printing portion with a varnish: and a gradation portion, which is attached to the film in a plan view The periphery of the covering is covered by the varnish in such a manner that the amount of the varnish decreases stepwise as the distance from the coating portion decreases. As long as the printing film of the present invention is used, it can be used to protect the printing portion from being noticeable. Therefore, as long as it is a film package as described above, the degree of freedom in designing the printed film and the package can be improved.

Further, the cigarette product may be, for example, a paper cigarette (filter cigarette, a double-cut cigarette (no filter)), a cigar (cigar), a cigarillo, or a cigarette (Snus). ), smelling incense Smoke, chewing cigarettes, electronic cigarettes, etc.

Means for solving the problems of the present invention can be employed as much as possible.

According to the present invention, it is possible to provide a printing film which can be used to protect the printing portion from being noticeable.

<Composition of film packaging>

The configuration of the film package (also simply referred to as "package") 1 including the package 11 and the film 12 for packaging the package 11 will be described with reference to Fig. 1 . Fig. 1 is a perspective view of the package 1 before unsealing of the embodiment.

The package 11 included in the package 1 may be a hinge lid type package as shown, or may be another hard package or a soft package. The inside of the package 11 includes, for example, a bundle of cigarettes (not shown) coated with aluminum-coated metal paper.

The film 12 is, for example, a transparent (colorless transparent) polymer film, and is composed of, for example, a material such as polypropylene (PP), polyethylene (PE), or cellophane. Furthermore, the film 12 has at least a portion having a printed area 121. The printing area 121 is provided, for example, on the inner surface of the film 12 (that is, the inner side of the package 1 and the surface that is in contact with the package 11). Alternatively, film 12 can be a translucent or colored transparent film. Further, the film 12 having the printing region 121 is also referred to as a printing film of the present invention.

Furthermore, the film 12 has a tear tape (also referred to as a "tear strip") 122. The opening tape 122 is a belt-like member wound around the surface of the package member 11, and is attached to the inner surface of the film 12 (that is, the inner side of the package 1 and is in contact with the package member 11). ). The film 12 is provided with a slit in such a manner that the one end 1221 of the sealing tape 122 can be gripped, and the user can tear the film 12 by pulling the one end 1221 and can unpack the package 1.

<Composition of printed film>

Fig. 2 is a view for explaining the printing area 121. In addition, FIG. 2 is a plan view of a printed region 121 provided on a part of the film 12 from a front side of the film 12 (that is, an outer side of the package 1). The printing area 121 includes: printing the printing part 1211 with colored ink; coating the whole part of the printing part 1211 by varnish (also referred to as "shining lacquer") to protect the coating part 1212 of the printing part 1211; And a gradation portion 1213 provided around the coating portion 1212 in plan view.

The printing system applied to the printing unit 1211 can be performed by various methods such as gravure printing or UV (Ultraviolet) printing which can be printed on the film. Further, the printing unit 1211 is obtained by printing a region which is filled with black and a region which is shaded by oblique lines, and prints in different colors. Further, the coating portion 1212 and the gradation portion 1213 can be formed by printing using varnish instead of ink.

The varnish of the present embodiment does not contain a pigment-transparent paint, and is formed, for example, by dissolving a resin in a solvent. Further, the ink contains a pigmented colored paint such as a pigment mixed with a varnish. In the present embodiment, a conventional varnish and ink can be used.

The coating portion 1212 is provided to "clip" the printing portion 1211. In other words, by covering the printing portion 1211 with varnish, the surface can be smoothed and the abrasion resistance can be improved, so that, for example, the printing can be prevented from being peeled off by scratching. Furthermore, the blocking performance can also be improved by the coating portion 1212. That is, it is possible to suppress the films 12 from adhering to each other or the film 12 to the package 11.

The gradation portion 1213 is provided around the printing portion 1211, and the further away from the printing portion 1211 and the coating portion 1212, the varnish The quantity is reduced step by step. Fig. 3 is an enlarged view of the periphery of the printing area 121. Further, the gradation portion 1213 of Fig. 3 is displayed in a line parallel to the outline of the printing portion 1211 and the coating portion, and the amount of the varnish is schematically indicated by the thickness of the line and the interval between the lines. As shown in Fig. 3, the more the gradation portion 1213 is closer to the varnish of the printing portion 1211 and the coating portion 1212, the smaller the amount of varnish is from the printing portion 1211 and the coating portion 1212.

<Composition of Gradient Parts 1>

Fig. 4 shows an example of the configuration of the gradation portion 1213. In addition, FIG. 4 is an enlarged view of the printing region 121 provided in a part of the film 12 as viewed from the surface side of the film 12. In the film 12, the coating portion 1212 having an area larger than the area of the printing portion 1211 is formed so as to overlap the printing portion 1211. Further, a gradation portion 1213 is provided around the coating portion 1212. The gradation portion 1213 is arranged in such a manner that a point (also referred to as a "small area") formed of varnish is present. In addition, for ease of understanding, Figure 4 shows a dotted line useful to represent rows. The dots are arranged in a manner substantially parallel to the contour of the coating portion 1212. Further, in the example of Fig. 4, the line of dots is also substantially parallel to the outline of the printing portion 1211. Further, in the example of Fig. 4, as the distance from the coating portion 1212 is further (i.e., further away from the printing portion 1211), the number of dots per one row is less.

In the example of Fig. 4, although a line having a point substantially parallel to the outline of the coating portion 1212 is shown, the points may not be aligned in parallel. For example, it is also possible to arrange dots in a random or predetermined pattern in such a manner that the number of points per predetermined unit area is smaller as the distance from the coating portion 1212 is smaller. Here, the unit area can be divided into the gradation portion 1213. An area of any shape that is sized and contains a plurality of points within the shape. In other words, in the gradation portion 1213, the farther away from the coating portion 1212, the smaller the area of the region covered with the varnish per predetermined unit area becomes.

<Composition of Gradient Section 2>

Fig. 5 shows another example of the gradation portion 1213. In addition, FIG. 5 is also an enlarged view of the printed region 121 provided on a part of the film 12 as viewed from the surface side of the film 12. The gradation portion 1213 of Fig. 5 is also disposed such that the dots formed by the varnish are arranged substantially parallel to the outline of the coating portion 1212. In the example of Fig. 5, the smaller the distance from the coating portion 1212, the smaller the size of each dot becomes.

In the example of Fig. 5, although a line substantially parallel to the outline of the coating portion 1212 is also shown, the dots may not be arranged in parallel. For example, it is also possible to arrange the dots in a random or predetermined pattern in such a manner that the smaller the size of the dots from the coating portion 1212 is. In other words, in the gradation portion 1213, the farther away from the coating portion 1212, the smaller the area of the region covered with the varnish per predetermined unit area becomes.

<Structure of Gradient Section 3>

Fig. 6 shows another example of the gradation portion 1213. Further, Fig. 6 is also an enlarged view of the printing region 121 provided on a part of the film 12 as viewed from the surface side of the film 12. The gradation portion 1213 of Fig. 6 is also arranged such that a point formed by the varnish is substantially parallel to the outline of the coating portion 1212. In the example of Fig. 6, the distance from the coating portion 1212 becomes wider with the adjacent rows.

In the example of Fig. 6, although the points which are substantially parallel to the outline of the coating portion 1212 are also shown, the dots may not be arranged in parallel. For example, it is also possible to arrange the dots in a random or predetermined pattern in such a manner that the average of the distances between the points included in the predetermined unit area farther from the coating portion 1212 becomes wider. In other words, in the gradation portion 1213, the farther away from the coating portion 1212, the smaller the area of the region covered with the varnish per predetermined unit area becomes.

<Structure of Gradient Department 4>

Fig. 7 shows another example of the gradation portion 1213. Fig. 7 is a cross-sectional view taken along line A-A of the film 12 shown in Fig. 3. Further, as shown in FIG. 7, the printing portion 1211, the coating portion 1212, and the gradation portion 1213 are provided inside the film 12. In addition, the inner side of the film 12 means the side which contacts the package 11 of the package 1. The further the gradation of Fig. 7 is from the coating portion 1212, the thinner the thickness of the varnish becomes. In other words, in the gradation portion 1213, the farther away from the coating portion 1212, the amount of varnish per predetermined unit area gradually decreases. Such printing can be achieved, for example, by gravure printing (i.e., gravure transfer printing). The thickness of the varnish is not limited to a linear change when viewed in cross section, and may be, for example, a line substantially parallel to the outline of the coating portion 1212, and the varnish thickness as it goes further from the coating portion 1212 It is reduced in stages.

When the above-described configurations 1 to 4 are summarized, the distance of the gradation portion 1213 from the coating portion 1212 is gradually decreased, and the amount of the varnish is gradually reduced. Furthermore, if the above-described configurations 1 to 3 are summarized, the gradation portion 1213 is further away from the coating portion 1212, every predetermined The portion of the unit area covered with varnish is gradually becoming smaller.

The configuration of the gradation portion 1213 may be a combination of the configurations shown in the above configurations 1 to 4. In particular, the gradation portion 1213 is configured to have a point formed by the varnish in such a manner as to exhibit a line substantially parallel to the contour of the coating portion 1212, and the further the distance from the coating portion 1212, the thickness of the varnish becomes It is thinner and can make the coating more unobtrusive. Further, the gradation portion 1213 can also be formed to have a point formed by the varnish in such a manner as to exhibit a line substantially parallel to the contour of the coating portion 1212, and the distance is further reduced as the distance from the coating portion 1212 is further reduced. The number of points in the row, and the size of each point becomes smaller. Further, the further the distance from the coating portion 1212, the thinner the thickness of the varnish. Further, other combinations may be used, or three or more types may be combined.

In the configuration of Fig. 4 to Fig. 6, although the point of the rounded square is shown, the shape of the dot is not limited to this. The points can be various shapes such as a rectangle, other polygons, and an ellipse. Furthermore, the size of the points in FIGS. 4 to 6 is exaggerated for convenience of explanation, but may be an extent that is invisible to the naked eye. Further, although the dots shown by the broken lines in FIGS. 4 to 6 are 5 rows, the number of rows is not limited to 5.

Further, the line of the gradation portion 1213 shown in FIGS. 3 to 6 is formed so as to be substantially parallel to the outline of the printing portion 1211 and the coating portion 1212 in plan view, but is not limited thereto. Aspect. Fig. 8 shows an example in which the outline of the printing portion 1211 is 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 or the contour of the coating portion 1212. At this time, for example, the wheel defined in the coating portion 1212 A plurality of shapes are interposed between the profile and the contour of the gradation portion 1213, and the inside of each region is printed in such a manner that the amount of varnish decreases as the distance from the coating portion 1212 is further away.

According to the gradation portion 1213 of the present embodiment, since the amount of varnish is gradually reduced from the coating portion 1212 on the film 12 to the portion not covered with the varnish, the outline of the coating portion 1212 can be made inconspicuous. That is, according to the gradation portion 1213, the coating portion 1212 can be naturally coordinated with the boundary thereof. Further, since the convex edge is not formed around the coating portion 1212, the reproducibility of the intended design can be improved. Further, by blurring the outline of the coating portion 1212, an opacity can be expressed.

<Manufacturing method>

A method of manufacturing a printed film will be described using Figs. 9 and 10 . First, as shown in Fig. 9, a printing portion 1211 is formed on the film 12. Here, the side on which the printing is applied to the two faces of the film 12 is also referred to as a printing surface. The printing surface is the side in contact with the package 11 in the state in which the package 11 is wrapped with the film 12, and is the inner side of the package 1. Therefore, when viewed from the printing surface, the characters and figures of the printing unit 1211 are opposite to the inside and the outside of the characters and figures 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 portion 1212 and the gradation portion 1213 are also disposed on the printing surface. In the present embodiment, the coating portion 1212 is superposed so as to cover the entire printing portion 1211. That is, the coating portion 1212 is printed on the printing portion 1211 at the mating position. Furthermore, the area of the coating portion 1212 is formed to be larger than the area of the printing portion 1211. Furthermore, in the coating department A gradation portion 1213 is printed around the periphery of 1212. Further, the coating portion 1212 and the gradation portion 1213 can be simultaneously printed.

According to the above steps, the coating portion 1212 for protecting the printing portion 1211 by the ink and the gradation portion 1213 for naturally coordinating the boundary between the coating portion 1212 and the periphery thereof can be printed.

Further, although the printing area 121 is present on the inner side of the package 1, the printing may be scraped off and peeled off, but the printing area 121 may be provided on the outer side of the package 1 (that is, the surface of the film 12). At this time, the characters and the graphics of the printing unit 1211 are not reversed and printed. In the case of the film 12, in the case where a translucent film or a transparent film with a color is used, when printing is applied to the surface of the package 1 on the side of the package 11 of the film 1, the color of the film 12 overlaps with printing. Area 121. If printing is not applied to the surface of the film 12, the color of the film 12 does not overlap the printing area 121, and the color loyal to the design can be reproduced.

<Comparative Example 1>

Next, the film 22 of the comparative example will be described using FIG. In addition, FIG. 11 is a view of the printing 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 portion 2211 printed with colored ink, and a coating portion 2212 coated with white ink so as to cover the entire printing portion 2211. When the printed portion 2211 is covered with white ink, for example, the printed portion 2211 can be prevented from being scraped off and peeled off.

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

<Comparative Example 2>

Next, the film 32 of the comparative example will be described using Fig. 12 . Further, Fig. 12 also shows a printing region 321 provided on a part of the film 32 as viewed from the surface side of the film 32. The printing area 321 includes a printing portion 3211 printed with colored ink, and a coating portion 3212 coated with varnish so as to cover the entire printing portion 3211. Among them, the printing area 321 does not have a gradation portion. When the printed portion 3211 is covered with the varnish, for example, the printed portion 3211 can be prevented from being scraped off and peeled off.

In the case of Comparative Example 2, even if a transparent varnish was used, the outline of the portion coated with the varnish became conspicuous. That is, in the film 32, the portion coated with the varnish and the uncoated portion have a difference in thickness, and the material is also different due to the difference in the presence or absence of the varnish. Therefore, the transmittance of visible light is also generated. difference. Therefore, the boundary between the coating portion 3212 and its surroundings appears.

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. Thus, in accordance with an embodiment of the present invention, a printed film that is naturally coordinated with the periphery of the coating portion 1212 can be provided. In particular, packages 11 such as cigarette products are also required to be limited by the warning display of a predetermined size, and the degree of freedom in acceptable design performance is limited. By applying a pattern to the film 12 for packaging the package 11 when the pattern of the package 11 is overlapped, the pattern of the package 11 and the pattern of the film 12 can be achieved by reducing the design limitation of the film 12. It is useful to multiply the design.

In the above-described example, the contents of the contents accommodated in the package include cigarette products such as filter cigarettes and double-cut cigarettes. However, the object to be stored is not limited thereto, and may be, for example, food, stationery, or the like.
