Description

  The present invention relates to a wrapping label continuum including a wrapping label that is wound around a container.

Conventionally, after pasting the back of the first side end of the film on the body of various containers such as beverage containers, seasoning containers, cosmetic containers, and medical containers, and winding this film around the body, A winding label that is wound around a container by attaching the back surface of the second side end portion of the film to the surface of the first side end portion is known (Patent Document 1).
Such a winding label is provided in the form of a continuous body in which a plurality of the winding labels are continuously connected in the length direction (hereinafter referred to as a winding label continuous body). The winding label is cut out.
Specifically, the wound label continuum is stored and transported in the state of being wound around a roll with the length direction being the circumferential direction, and is filled into a labeler (device for attaching the label to the container) at the time of use. The The labeler pulls the wound label continuous body from the roll, transports it to the mounting site on the transport line, and cuts the wound label continuous body just before the mounting site to obtain one wound label. Wrap around the container.
From such a mounting form, it is possible to smoothly pull out the wound label continuous body from the roll, to be able to smoothly convey it on a conveyance line, etc., to prevent damage to the commercial value of the label due to damage during conveyance, etc. Desired.

  By the way, although various printings such as a trade name are performed on the winding label, a winding label provided with a metallic printing layer exhibiting a metallic color is also known. Such a metallic printing layer is provided on the back side of the film from the viewpoint of preventing scratches. Further, in order to smoothly convey the wound label continuous body on the labeler transportation line, a transparent side is provided on the back side of the metallic print layer and on the backmost side of the wound label continuous body (winding label). A resin layer is provided.

  However, the wrapping label continuum provided with the metallic printing layer has a problem that blocking is likely to occur during storage in a state of being wound on a roll. When blocking occurs, the wound label continuous body cannot be pulled out smoothly, and an improvement thereof is required.

JP 2007-003724 A

  It is an object of the present invention to provide a winding label continuous body and a winding label that hardly cause blocking and can be smoothly conveyed by a labeler.

As a result of intensive research on the cause of blocking, the present inventors have found that the conventional metallic printing layer has a large amount of residual solvent, and further, the transparent resin layer provided on the back side of the metallic printing layer has a solvent. Since it remains, a relatively large amount of solvent remains in the wound label continuous body, and the printing layer containing the solvent causes blocking while the wound label continuous body is in a roll state. I found.
In this regard, if the transparent resin layer is omitted, the residual amount of solvent in the wound label continuous body is also reduced, and blocking can be effectively prevented. However, if this is done, the slipping property on the back side of the wound label continuous body is reduced. The labeler may not be able to transport smoothly.
Thus, the present inventors have conducted extensive research and found that the back surface of the white printed layer has good slipperiness, thereby completing the present invention.

In the winding label continuous body of the present invention, a plurality of winding labels are connected in the length direction, and the winding label is a film, a metallic printed layer provided on the back side of the film, and the film Provided in a region other than the region where the all-white print layer is provided on the back side of the film and the all-white print layer provided in a part of the back side and white ink layered without gaps A transparent resin layer, and an outermost back surface is constituted only by a back surface of the all white printed layer and a back surface of the transparent resin layer.

The wrapping label continuum of the present invention is provided on the back side of the film with an all-white print layer in which white ink is continuous without any gap and a transparent resin layer, and the back side of the continuum is an all-white print layer. It is comprised only by the back surface and the back surface of a transparent resin layer. For this reason, the wound label continuous body can be smoothly conveyed by a labeler, and the back side of the wound label continuous body can be suppressed from being damaged.
Furthermore, since the wrapping label continuous body of the present invention has a transparent resin layer provided in a region other than the region in which the all white printed layer is provided, the transparent resin layer is provided on the entire back surface side. The amount of the transparent resin layer per one wound label is smaller than that of a conventional wound label continuous body. For this reason, for example, even when the metallic printing layer or the transparent resin layer of the present invention is formed with an ink containing an organic solvent, the residual amount of solvent per wound label becomes relatively small and blocking. It is possible to construct a wrapping label continuum that is difficult to generate.

  In a preferred wound label continuous body of the present invention, a transparent surface protective layer is further provided on the surface side of the film. Such a wound label continuous body is less likely to cause blocking, and the surface of the wound label can be prevented from being damaged during the transportation of the wound label continuous body or the container equipped with the wound label.

In a preferable wound label continuous body of the present invention, the all white print layer is provided on the back side of the film so as to overlap a part or all of the back side of the metallic print layer.
In a preferable wound label continuous body of the present invention, the all white print layer contains resin fine particles.
In the preferred wrapping label continuous body of the present invention, a partial white printing layer in which white ink is scattered to form a layer is further provided on the back side of the film, and the back side of the partial white printing layer is provided. A transparent resin layer is provided.

According to another aspect of the present invention, a wound label is provided.
The winding label of the present invention is provided on a film, a transparent surface protective layer provided on the front side of the film, a metallic printing layer provided on the back side of the film, and a part on the back side of the film. And an all-white printing layer in which white ink is continuously formed without gaps, and a transparent resin layer provided in a region other than the region where the all-white printing layer is provided on the back side of the film, have a, outermost backside, said is constituted only by the rear surface of the transparent resin layer and the back surface of the total white printing layer.

Since the winding label continuous body of this invention does not produce blocking easily, it can draw out smoothly from the state wound on the roll.
Furthermore, since the winding label continuous body of this invention can be smoothly conveyed with a labeler, the mounting of the winding label using a labeler to the container can be performed continuously and smoothly without stopping in the middle.

However, in this specification, the “surface” of a certain member or layer refers to the outer surface when the wound label is wound around the container, and the “back surface” refers to the inner side (the container when the wound label is wound around the container. Side). The numerical range represented by “to” means a numerical range including numerical values before and after “to” as a lower limit value and an upper limit value.
It should be noted that the shape, size, thickness of each layer, the relative ratio thereof, and the like shown in each drawing are different from actual dimensions.

[Continuous winding label and winding label]
As shown in FIG. 1, the wound label continuous body 10 has a long belt shape as a whole, and is usually wound and stored on a roll and transported in that state.
The winding label continuous body 10 is conceptually configured by continuously connecting a plurality of winding labels 1 in the length direction. In other words, the wound label continuous body 10 is provided with a desired pattern in which each layer such as a metallic print layer described later is provided on a long strip film whose length direction is sufficiently long with respect to the width direction. It is repeatedly formed in the vertical direction. Each of the layers formed in one pattern is a wound label 1, and each wound label 1 is obtained by cutting a wound label continuous body 10 in the width direction between adjacent patterns. can get. In addition, the arrow of FIG. 1 is the boundary part of an adjacent pattern (adjacent winding label 1), Comprising: The cut location at the time of obtaining the winding label 1 from the winding label continuous body 10 is shown.
Thus, since the winding label continuous body 10 is one in which the winding label 1 is continuously connected, the layer configuration of the winding label 1 will be specifically described below, and the layer configuration of the winding label continuous body 10 will be described. Description is omitted.

  As shown in FIGS. 2 to 4, the winding label 1 according to the first embodiment includes a film 2, a transparent surface protective layer 3 provided on the surface side of the film 2, and a back surface side of the film 2. Metallic print layer 4 provided on the back side, all white print layer 5 provided on the back side of the film 2 and layered with white ink without gaps, and the all white print on the back side of the film 2 And a transparent resin layer 6 provided in a region other than the region where the layer 5 is provided.

<Film>
The film 2 is formed in a predetermined shape in plan view. The planar view shape of the film 2 is, for example, a rectangular shape or a square shape. In the illustrated example, the film 2 is formed in a rectangular shape in plan view in which the horizontal direction is larger than the vertical direction.
In addition, the winding label continuous body 10 shown in FIG. 1 has the winding label 1 connected continuously by making the horizontal direction of the film 2 into the length direction. But the winding label continuous body of this invention may be the aspect which the winding label 1 is connected continuously by making the vertical direction of the film 2 into the length direction.
The film 2 is not particularly limited as long as it is a transparent and flexible sheet material, and representative examples include a synthetic resin film and a laminated film including a synthetic resin film.

The material of the synthetic resin film is not particularly limited, and conventionally known materials can be used. For example, polyester resins such as polyethylene terephthalate and polylactic acid; polyolefin resins such as polypropylene, polyethylene and cyclic olefin resins; polystyrene And polystyrene resins such as styrene-butadiene copolymer; and one or a mixture of two or more selected from thermoplastic resins such as polyvinyl chloride resins. Among these, a film containing a polyolefin resin or a film containing a polyester resin is preferable.
For example, polyolefin resin films such as polypropylene and polyethylene have low wettability. When using a film having a resin with low wettability on the front and back surfaces, it is preferable to perform a surface modification treatment such as a corona discharge treatment as necessary. For example, as the film 2, a polyolefin resin film having a surface modification treatment such as a corona discharge treatment applied to at least one of the back surface and the front surface (preferably both the back surface and the front surface) is used.
The transparency of the film 2 is not limited as long as the metal color of the metallic print layer 4 provided on the back side of the film 2 can be visually recognized from the front side of the film 2. For example, the total light transmittance of the transparent film 2 is, for example, 70% or more, preferably 80% or more, and more preferably 90% or more. In this specification, a total light transmittance means the value measured by the measuring method based on JISK7361 (the test method of the total light transmittance of a plastic-transparent material).

  The film 2 may be a non-heat-shrinkable and / or non-self-stretchable film, or may have a heat-shrinkable and / or self-stretchable property. Among these, the film 2 used in the present invention is preferably a biaxially stretched film, and more preferably a non-heat-shrinkable biaxially stretched film. Specifically, the film 2 is preferably a non-heat-shrinkable biaxially stretched polyolefin resin film or a biaxially stretched polyester resin film, and a biaxially stretched polypropylene resin film or a biaxially stretched polyethylene terephthalate resin film. More preferred. In addition, as for the biaxially stretched polyolefin film (biaxially stretched polypropylene film), it is preferable that at least one of the front surface and the back surface is subjected to surface modification treatment such as corona discharge treatment as described above.

  The non-heat-shrinkable film refers to a film having substantially no heat-shrinkability described later, and the non-self-stretching refers to a film having substantially no self-stretchability described later. Examples of the film having substantially no heat shrinkability include those having a heat shrinkage rate of 5% or less in the lateral direction, which will be described later, and a heat shrinkage rate of 5% or less in the vertical direction.

The heat-shrinkable film is also called a shrink film and has a property of shrinking when heated to a predetermined temperature (for example, 70 ° C. to 100 ° C.). The self-stretchable film is also called a stretch film or the like, and has a property of being stretched by applying an expansion force (without the heat shrinkability as described above) and almost restored by releasing the expansion force. . A film having heat shrinkability and self-stretchability is also called a stretch shrink film and has both the heat shrinkability and self-stretchability.
As the film having heat shrinkability, a film capable of being thermally shrunk at least in the lateral direction at a heat shrink temperature (for example, 70 ° C. to 100 ° C.) is used. Moreover, the film which has heat shrinkability may be heat-shrinkable also in the vertical direction (the vertical direction is the direction perpendicular to the horizontal direction in the plane of the film). For example, the film having heat shrinkability preferably has a heat shrinkage rate in the transverse direction of 30% or more when heated to 85 ° C., more preferably 40% or more, and particularly preferably 50% or more. . Moreover, when the film can be thermally contracted in the longitudinal direction, the thermal shrinkage rate in the longitudinal direction when the film is heated to 85 ° C. is 1% to 15%, preferably 1% to 10%. is there.
Here, the heat shrinkage rate when heated to 85 ° C. is the length (original length) of the heat-shrinkable film before heating and the film is immersed in warm water at 85 ° C. for 10 seconds. It is the ratio of the length of the film (length after immersion). The said heat shrinkage rate is calculated | required by substituting into a following formula.
Formula: heat shrinkage rate (%) = [{(original length in the transverse direction (or longitudinal direction) of the film) − (length after immersion in the transverse direction (or longitudinal direction) of the film)} / (of the film Original length in the horizontal direction (or vertical direction)]] × 100.
The thickness of the film 2 is not particularly limited, and is, for example, 10 μm to 120 μm, preferably 10 μm to 50 μm, and more preferably 12 μm to 40 μm. Generally, a film having a small thickness has a long winding length when wound on a roll (that is, when the film is wound on a roll to have a diameter of, for example, 1 m, the film having a smaller thickness has a length wound on the roll. It tends to cause blocking). In this regard, according to the present invention, blocking can be effectively prevented even when a film having the above thickness is used.

A transparent surface protective layer 3 is provided on the surface side of the film 2. The surface protective layer 3 is formed by a continuous layer of the forming material without gaps. Specifically, the surface protective layer forming material is layered in the surface direction of the film 2 without gaps on the surface of the film 2. The surface protective layer 3 is provided as necessary. But when using the film 2 by which surface modification processes, such as a corona discharge process, are performed on the surface, it is preferable that the surface protective layer 3 is provided in order to prevent blocking.
The transparency of the surface protective layer 3 should just be what can permeate | transmit visible light so that the metallic color etc. of the metallic printing layer 4 provided in the back surface side of the film 2 can be visually recognized from the surface side of the film 2. FIG. For example, the total light transmittance of the transparent surface protective layer 3 is, for example, 70% or more, preferably 80% or more, and more preferably 90% or more. The total light transmittance refers to a value measured by a measurement method based on JIS K7361 using a sample in which the surface protective layer 3 is provided on the surface of the film 2 having a total light transmittance of 90% or more.
The surface protective layer 3 is provided directly on the surface of the film 2. But when the transparent arbitrary functional layer (not shown) is provided in the surface of the film 2, the surface protective layer 3 is provided in the surface of the functional layer.

The surface protective layer 3 may be provided on the entire surface side of the film 2 or may be provided on a part of the surface side of the film 2. For example, the surface protective layer 3 is provided on the surface side of the film 2 excluding the side end portion 2a on the first lateral side of the film 2 (hereinafter referred to as the first side end portion 2a). The first side end 2a of the film 2 refers to a region extending in a strip shape in the vertical direction on the first side in the horizontal direction. Further, the second side end 2b of the film 2 is a side end facing the first side end 2a in the lateral direction of the film 2, and an area extending in the longitudinal direction on the second side in the lateral direction. Say.
As will be described later, when the winding label 1 is attached to the container, the back surface of the second side end 2b is bonded to the surface of the first side end 2a via an adhesive. Since the surface of the part 2a is the surface of the film 2, the adhesive can be favorably bonded. In particular, when the surface of the film 2 is subjected to a surface modification treatment such as a corona discharge treatment, the adhesion becomes better.
As will be described later, the wound label 1 wound around the container at the time of mounting is cylindrical, but the surface protective layer 3 is provided on the surface of the film 2 excluding the surface of the first side end 2a. The outermost side of the wound label 1 in the form of a cylinder is constituted by the surface protective layer 3. For this reason, it is possible to effectively prevent the wound label 1 from being damaged during storage and transportation of the labeled container.

A design print layer 7 is provided on the back side of the film 2. The design printing layer 7 is a printing layer in which a desired design such as a trade name or a pattern is expressed using a design printing ink.
The design print layer 7 is provided directly on the back surface of the film 2. However, when a transparent arbitrary functional layer (not shown) is provided on the back surface of the film 2, the design print layer 7 is provided on the surface of the functional layer (the same applies to the transparent resin layer 6 and the like). ).
The design print layer 7 may be provided on the entire back side of the film 2 or may be provided on a part of the back side of the film 2. For example, as shown in FIG. 4, the design print layer 7 is provided on the back side of the film 2 excluding the side end portion 2 c on the first side in the longitudinal direction and the side end portion 2 d on the second side in the vertical direction. Yes. The side end portions 2c and 2d on the first and second sides in the longitudinal direction of the film 2 are side end portions facing each other in the longitudinal direction, and are regions extending in a strip shape in the lateral direction on both sides in the longitudinal direction.
In the illustrated example, the design print layer 7 provided in a region other than the side end portions 2c and 2d on the first side and the second side in the vertical direction is represented as one layer. Depending on the design represented by (1), there may be a portion where the design print layer 7 is not formed in some areas (hereinafter referred to as a design blank portion). Design blanks are not shown. For example, if the design is a figure “◯”, a design printing layer is provided by printing a design printing ink on a film so that the above-mentioned ○ can be visually recognized. There is no printing ink, and these places are design blank places. In other words, the design blank portion means a portion where the color resulting from the design printing ink cannot be visually recognized when viewed macroscopically. However, when the design print layer is viewed microscopically, there may be a slight gap between the innumerable design print inks, but the design print layer here can be viewed macroscopically to visually recognize the design. It means the layer to which design printing ink adhered.

Further, a metallic print layer 4 is provided on the back side of the film 2. The metallic printing layer 4 may be a layer in which the metallic ink is continuous without a gap, or may be a layer in which the metallic ink is scattered. Specifically, the metallic ink is continuous in the plane direction of the film 2 to form a layer, or the metallic ink is scattered in the plane direction of the film 2 to form a layer.
The metallic print layer 4 may be provided on the entire back side of the film 2 or may be provided on a part of the back side of the film 2. For example, the metallic print layer 4 is provided on the back side of the film 2 except for the side end 2c on the first side in the vertical direction and the side end 2d on the second side in the vertical direction. As shown in FIGS. 3 and 4, the metallic print layer 4 is provided with a portion overlapping the back surface of the design print layer 7. That is, the metallic print layer 4 may be provided so as to overlap the design print layer 7 as a whole in plan perspective, or may be provided smaller than the design print layer 7, or may be provided by design printing. It may be larger than the layer 7. In addition, in this specification, a plane perspective means conceptually making a line of sight perpendicular | vertical with respect to the surface of the film 2, and seeing through the layer in the direction of the line of sight. However, even when the metallic printing layer 4 overlaps the design printing layer 7, there are cases where there are design blank portions in some places as described above. Therefore, in the design blank portion, the metallic printing layer 4 is formed on the film 2. Provided directly on the back side.
Moreover, when the metallic printing layer 4 is provided in the said design blank part, either the transparent resin layer 6 mentioned later or the all white printing layer 5 may be provided in the back surface side of the metallic printing layer 4. However, preferably, the all white print layer 5 is provided on at least a part of the back side of the metallic print layer 4 provided in the design blank portion.

In the illustrated example, the metallic print layer 4 is smaller than the design print layer 7 in plan perspective. In the illustrated example, the metallic printing layer 4 provided in a predetermined area on the back surface of the design printing layer 7 is represented as one layer, but the metallic printing layer 4 is not formed in some areas in the area. (Hereinafter referred to as metallic blank). Metallic blanks are not shown. However, the metallic blank portion means a portion where the metal color caused by the metallic ink cannot be visually recognized when viewed macroscopically.
The area of the metallic printing layer 4 is not particularly limited. For example, when the area of the back surface of the film 2 is 100%, the area occupied by the metallic printing layer 4 is 5% to 95%, preferably 30. % To 90%.

Further, an all white print layer 5 is provided on the back side of the film 2.
The all-white print layer 5 is a print layer in which white ink is continuously formed without any gaps and has a white color. Specifically, the white ink is layered in the surface direction of the film 2 without gaps.
The all white print layer 5 is provided on a part of the back side of the film 2. For example, the all white print layer 5 is provided on the back side of the film 2 except for the side end 2c on the first side in the vertical direction and the side end 2d on the second side in the vertical direction.
Further, the all white print layer 5 may be provided so as to include a part or all of the back surface of the metallic print layer 4, or may be provided so as not to overlap the back surface of the metallic print layer 4.
For example, as shown in FIGS. 3 and 4, the all white print layer 5 is provided with a portion overlapping the back surface of the metallic print layer 4. That is, the all-white print layer 5 may be provided so as to overlap the metallic print layer 4 as a whole in plan perspective, or may be provided smaller than the metallic print layer 4, or metallic It may be larger than the printing layer 4.
However, even when the all-white print layer 5 is overlapped with the metallic print layer 4, it may have metallic blank portions in some places as described above. It is directly provided on the back surface of the printing layer 7 or the back surface of the film 2.
In the illustrated example, the all white print layer 5 is provided so as to overlap with the metallic print layer 4 as a whole in plan perspective. In the illustrated example, the all white print layer 5 provided in a predetermined area on the back surface of the metallic print layer 4 is represented as one layer, but the all white print layer 5 is formed in some areas in the area. There may be places that are not.

Further, a transparent resin layer 6 is provided on the back side of the film 2. The transparent resin layer 6 has a layer in which the forming materials are connected without gaps. Specifically, the forming material of the resin layer 6 is formed in a continuous manner in the surface direction of the film 2 without a gap.
The transparency of the surface protective layer 3 of the resin layer 6 may be any as long as it transmits visible light so that the design print layer 7 provided on the back side of the film 2 can be seen from the back side of the film 2. . For example, the total light transmittance of the transparent resin layer 6 is, for example, 70% or more, preferably 80% or more, and more preferably 90% or more. The total light transmittance is a value measured by a measuring method based on JIS K7361 using a sample in which the resin layer 6 is provided on the back surface of the film 2 having a total light transmittance of 90% or more.
The transparent resin layer 6 is directly provided on the back surface of the design print layer 7 or the back surface of the metallic print layer 4. In the design blank part, the transparent resin layer 6 may be provided directly on the back surface of the film 2. When the transparent resin layer 6 is directly provided on the back surface of the design blank part, the part is transparent. A winding label 1 having such a transparent portion is also a preferred embodiment of the present invention. In addition, in the case of the design printing layer 7 formed with the intention of making the design visible through (such a design printing layer is formed using a design printing ink having high translucency), In order not to reduce the show-through of the design, it is preferable to provide the transparent resin layer 6 directly on the back surface of the design printing layer 7. When the transparent resin layer 6 is directly provided on the back surface of the design printing layer 7 having high translucency, the portion is excellent in transparency.

The transparent resin layer 6 is provided in a region other than the region where the all white print layer 5 is provided. Therefore, the rearmost side of the film 2 is constituted by the transparent resin layer 6 and the all-white print layer 5, and the backside of the resin layer 6 and the backside of the all-white print layer 5 are the outermost side (winding) The rearmost surface of the label 1 is configured. However, it should be noted that the edge of the resin layer 6 and the edge of the all white print layer 5 may slightly overlap at the boundary between the resin layer 6 and the all white print layer 5. This is because it is often difficult in practice to form the layers so that the resin layer 6 and the all white print layer 5 do not overlap at all.
For example, in the illustrated example, the transparent resin layer 6 includes the first side end 2 a, the second side end 2 b, the vertical first side end 2 c, and the vertical second in the back side of the film 2. It is provided on the side end 2d. The transparent resin layer 6 may be provided directly on the back surface of the design print layer 7, or may be provided directly on the back surface of the film 2, or the back surface of the design print layer 7 and the film 2 may be provided. It may be provided straddling the back surface.
The ratio of the resin layer 6 and the all white print layer 5 is not particularly limited. For example, when viewed from the back side of the film 2, the area of the resin layer 6: the area of the all white print layer 5 = 95: 5 to 5: 95, preferably 70:30 to 10:90.

The metallic print layer 4 is formed using, for example, a metallic ink exhibiting a metallic color.
Metallic ink is an organic solvent, resin component, metal fine particles and ink containing various additives as required (solvent-containing ink containing metal fine particles); substantially free of organic solvent, metal fine particles, resin component and necessary Accordingly, ink containing various additives (solvent-free ink containing metal fine particles);
As the solvent-containing ink and the solventless ink of the metallic ink, a solvent, a water evaporation type, a reaction type, or the like as described in the medium ink can be used on the condition that metal fine particles are included. The solvent evaporation type, the water evaporation type and the reaction type in the metallic ink can be appropriately selected from those exemplified in the medium ink. The metallic ink may contain some colorant (pigment or dye) as an additive as long as the brightness of the metal fine particles is not impaired.
According to the present invention, even when a solvent-containing ink is used as the metallic ink, the amount of solvent remaining per wound label can be reduced. For this reason, even when the metallic printing layer 4 is formed of a solvent-containing ink containing metal fine particles, the wound label continuous body 10 that is unlikely to cause blocking can be configured.

The metal fine particles are not particularly limited, and examples thereof include aluminum powder, silver powder, zinc powder, stainless steel powder, and nickel powder. It is also possible to use a metal fine particle paste in which metal fine particles such as aluminum powder are added to a solvent or a surface treatment agent. Aluminum powder (including aluminum powder paste) is preferably used because it is excellent in shine and is relatively inexpensive. The aluminum powder may be a leafing type, a non-leafing type, or a vapor-deposited aluminum powder produced by peeling and crushing a vapor deposition layer.
Although content of metal microparticles is not specifically limited, For example, it is 3 mass% or more with respect to the whole quantity of the metallic printing layer 4. FIG. If the metal fine particles in the metallic printing layer 4 are less than 3% by mass, the metallic printing layer 4 may not produce a sufficient metallic luster color. Preferably, the content of the metal fine particles is 3% by mass to 50% by mass, and more preferably 5% by mass to 40% by mass with respect to the total amount of the metallic print layer 4.

The metallic printing layer 4 is formed by applying the metallic ink to the back side of the film 2 and drying the organic solvent by a known printing method. In addition, when the reaction type or moisture evaporation type metallic ink is used, the metallic printing layer 4 can be formed by solidifying the ink according to the solidification method.
Although the thickness of the said metallic printing layer 4 is not specifically limited, For example, they are 0.1 micrometer-5 micrometers.

<Formation of all white printing layer>

The size of the resin fine particles is not particularly limited. The size of the resin fine particles is, for example, an average particle diameter of 1 μm to 20 μm, preferably 2 μm to 15 μm.
The resin fine particles are preferably larger than the white pigment.
The resin fine particles may be mixed with those having different particle diameters, but preferably resin fine particles having a uniform particle diameter are used. The resin fine particles having a uniform particle diameter include a range of ± 5% in particle size error, and preferably include a range of ± 2% in particle size error.
However, the particle size of the resin fine particles is a value obtained by arithmetically averaging the results of measuring the diameters of a plurality of arbitrary resin fine particles (or the short diameter in the case of a non-sphere) by an image analysis method.
The content of the resin fine particles in the all white print layer 5 is not particularly limited, but is, for example, 0.1% by mass to 10% by mass, preferably 1% by mass with respect to the total amount of the all white print layer 5. ˜5 mass%. If the amount of the resin fine particles is too small, the effect of improving the slipping property is not achieved. If the amount is too large, the relative amount of the white pigment in the all white print layer 5 decreases.

The all white printing layer 5 is formed by applying the white ink to the back side of the film 2 and drying the organic solvent by a known printing method. In addition, when the reaction type or moisture evaporation type white ink is used, the all white printing layer 5 can be formed by solidifying the ink according to the solidification method.

For example, as the medium ink for forming the transparent resin layer 6, a solvent-containing ink containing a two-component reaction type urethane resin as a resin component can be used.
Preferably, as a material for forming the transparent resin layer 6, a medium ink containing a lubricant or a medium ink containing resin fine particles is used. Specific examples of the lubricant and the resin fine particles are as described above.
According to the present invention, even when a solvent-containing ink is used as the material for forming the transparent resin layer 6, the amount of solvent remaining per wound label can be reduced.
The transparent resin layer 6 is formed by applying the forming material to the back side of the film 2 by a known printing method.

Furthermore, the wound label continuous body 10 of the present invention is less likely to cause blocking in a state of being wound on a roll.
In general, in a state where a wound label continuous body having a large amount of solvent remaining is wound around a roll, blocking is likely to occur due to softening of the resin by the solvent and application of winding pressure. The conventional wrapping label continuum has a large amount of solvent remaining and is likely to cause blocking.
In this regard, in the wound label continuous body 10 of the present invention, since the transparent resin layer 6 is provided in a region other than the region where the all white print layer 5 is provided, the resin layer 6 per one wound label.
