Description

  The present invention relates to a printed label for containers that is mounted on at least a part of the outer periphery of a container such as a metal can filled with soft drinks or alcoholic beverages.

Conventionally, as containers filled with soft drinks, alcoholic beverages, etc., metal cans such as aluminum cans and steel cans, in particular, so-called laminate cans in which plastic films are laminated on the inner surface side or inner and outer surfaces of those metal cans In addition, a surface coating layer containing a thermosetting amino resin or the like has been provided for the purpose of preventing scratches on the can or improving the glitter. (For example, see Patent Documents 1 to 3)
However, in order to form such a surface coating layer, it was necessary to bake a metal can at a temperature of about 200 ° C. after printing a varnish containing an amino resin or the like.
Further, with only the above surface coating layer, it is difficult to obtain a high design property even though the glitter is improved and the gloss is obtained.

  Under such circumstances, the present invention eliminates the need for a baking process for metal cans and improves the design of containers such as metal cans by making them not only glossy but also matte. It is an object of the present invention to provide a printed label product.

As a result of intensive studies to solve the above problems, the present inventors have used a label that is attached, attached, crimped, wrapped, etc. to a container, and a matte coating layer and a glossy layer on the label surface. The inventors have found that the above-described problems can be solved by printing the printing layer on the front or back surface of the label. The present invention has been completed based on such findings.
That is, the gist of the present invention is as follows.
1. A label printed matter for a container provided with a printing layer on the front or back surface of a transparent substrate, wherein at least a part on the surface of the printed layer or a matte coating layer on at least a part on the surface of the transparent substrate; A label printed matter for a container, wherein the gloss layer is provided in that order or in the reverse order, or the matte coating layer and the gloss layer are provided in parallel.
2. 2. The printed label for containers according to 1 above, wherein the printed layer, the matte coating layer, and the glossy layer are all printed by a gravure method.
3. 3. The label printed matter for a container according to 1 or 2 above, wherein the matte coating layer and the glossy layer are made of a varnish containing at least a melamine resin, a polyester resin and a wax.
4). 4. The printed label for containers according to any one of 1 to 3, wherein the varnish constituting the matte coating layer further contains a matting agent.

  According to the present invention, without printing directly on the laminate surface of the metal can, it is possible to eliminate the baking process of the metal can by attaching the label printed matter to the container, mounting, crimping, packaging, etc. By providing both a matte coating layer and a glossy layer, it is possible to provide a printed matter that can improve not only the glossiness but also the matteness and enhance the design of containers such as metal cans.

Using the above ink composition, it was appropriately diluted so as to have a coating film thickness after drying of 3 to 6 μm, and was subjected to gravure printing.

4). Transparent substrate A transparent non-heat-shrinkable polyethylene terephthalate film (thickness 16 μm, heat shrinkage 3% or less) was used.

5). Adhesive layer Urethane / isocyanate-based adhesive [Dai Nippon Ink Chemical Co., Ltd., Dick Dry {LX703A (main agent), KR90 (curing agent)}] is roll-coated on the back side of the printed label and the adhesive layer (thickness) 2 μm) was formed.

Examples 1 and 2
The label printed matter of Example 1 and 2 was produced by the structure (FIG. 7) of the label printed matter shown in Table 2.
On the outer surface of the transparent non-heat-shrinkable polyethylene terephthalate film, as a colored layer 12b, black ink for solid printing, iron yellow ink for solid printing, and white ink for solid printing are mixed and gravure printed, and a pattern is printed on the outer side of the colored layer 12b. Gravure printing of the woodgrain pattern pattern using yellow, red, blue and black inks for the pattern as the layer 12a, the matte varnish shown in Table 1 as the matte coating layer 13 on the outside, and further the outside In addition, using gloss varnish shown in Table 1, a pattern pattern overlapping the pattern pattern of the pattern layer 12a was gravure printed at the same position as the pattern layer 12a to obtain a glossy layer 14. The adhesive layer was further laminated by roll coating on the back surface of the obtained label printed matter. These label prints were evaluated for friction resistance and design properties. The results are shown in Table 2.

Examples 3 and 4
A label printed matter was produced in the same manner as in Examples 1 and 2, except that the configuration of FIG. 7 of the label printed matter of Examples 1 and 2 was changed to the configuration of FIG. The resulting printed label was evaluated for friction resistance and design. The results are shown in Table 2.

Examples 5-8
The label printed matter was produced like Example 1-4 except having changed the structure of FIG. 7 or 8 of the label printed matter of Examples 1-4 into the structure of FIG. 11 or FIG. The resulting printed label was evaluated for friction resistance and design. The results are shown in Table 3.

As is apparent from Tables 2 and 3, the printed container labels of Examples 1 to 8 can eliminate the need for a baking process for metal cans and are excellent in design.
In particular, Examples 1, 3, 5 and 7 were very excellent in both friction resistance and design properties.

  The printed label of the present invention is useful as a label for various containers such as metal cans such as aluminum cans and steel cans and plastic bottles such as polyethylene terephthalate (PET).
