Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for punching aluminum-deposited plastic films used as labels, packaging materials, etc.

・Conventional technology and its problems Beautiful appearance by vapor depositing aluminum on plastic film,
Labels or packaging materials with enhanced texture are known. In addition, there are also known labels or packaging materials in which the aluminum vapor-deposited surface is cut out so that the inside can be seen through, or in which the printing on the other surface that is pasted can be seen through.

The present invention relates to the latter punching method, and this conventional example will be explained based on FIG. 4.

In this method, letters or designs are printed on the surface of a transparent plastic film 01 using ordinary ink 02 and water-soluble ink 03. Next, an aluminum vapor deposition film 04 is formed on this printed surface, and the first step is washing with water. Then, as shown in FIG. 5, only the printed surface of the water-soluble ink 03 is washed off, and then the washed surface is subjected to a punching process 05 where aluminum is not deposited.

However, since the aluminum vapor-deposited surface of the film produced by the above method is directly exposed, it may be scratched or rubbed during the bag-making process, causing the vapor deposition to peel off, and the printing process, vapor deposition process, and water washing process are separated. This method has the drawback that the processed product must be rolled up into a roll and transported to the next process location, which increases the number of steps and costs.

Another processing method is to apply resin ink 0 on the vapor deposition surface 06 of the transparent plastic film 01 as shown in FIG.
7 to print a character 1 design, etc., remove the parts other than the printed surface by treating with acid or alkaline solution, punch out the removed parts as shown in Fig. 7, and further process as necessary. Accordingly, a method of laminating a transparent plastic film 08 on this surface is known.

However, even in this method, the same drawbacks as those described above exist, and a proposal for a solution to these problems is desired.

- Purpose of the present invention The present invention has been proposed in view of the above points, and its main purpose is to propose a processing method that can perform punching of an aluminum-deposited surface at a low cost.

・Structure of the present invention The main point of the processing method of the present invention is to print using ink on one side of a transparent plastic film, then apply a transparent or colored adhesive to this printed surface while aligning the design, and then A plastic film on which aluminum is vapor-deposited is pasted together, and when the adhesive has hardened, both are peeled off to move the design portion of the aluminum-vapor-deposited surface to the adhesive side, and punching is performed.

·Example An embodiment thereof will be explained below based on FIG. 1.

The transparent plastic film 1 is unwound from the unwind 2, passes through the tension control group 3, and passes through the first and second printing sections 7, each consisting of an ink pan 4, a plate cylinder 5, and an impression cylinder 6.
8, printing a is performed.

The thus printed plastic film 1 is then coated with a transparent urethane adhesive pan 9. When passing through the adhesive applicator 11 consisting of a pressure roll 10.1σ, the adhesive is applied to the printed surface while pattern alignment is performed. Note that the adhesive may be colored.

On the other hand, the aluminum vapor-deposited film 12 forming the aluminum vapor-deposited surface C is bonded to the adhesive surface by a bonding roll 13, 13', reaches the rewind 14, is rolled up into a roll, and then aged, i.e., the adhesive It is left until the hardening is complete.゛Figure 2 shows a cross section of the film after this bonding.

Next, after the adhesive has completely cured, the aluminum vapor-deposited film 12 is peeled off as shown in FIG. When this peeling is performed, the aluminum vapor-deposited surface C adheres only to the adhesive layer, and the aluminum vapor-deposited surface C does not adhere to the area where the adhesive layer is not present.

As a result, the portion d of the plastic film 1 to which the adhesive layer is not applied can be seen through, but the other portions cannot be seen through. In this way, it is possible to punch out any single character part of the design.

Note that in the above embodiment, attention was paid to the punched portion d, but if attention is paid to the side of the aluminum vapor-deposited film 12, the residual aluminum vapor-deposited surface on this side will reveal designs and letters, so this side may be used as a label or It can also be used as a packaging material.

The aluminum vapor-deposited surface C that has been punched out in this manner may be left as is, but if it is used as a packaging material, a sealant film such as a polyethylene film is bonded to the surface C.

In addition, for the plastic film 1 side in the examples, polyester, acetate,
Hard polyvinyl chloride film, cellophane, heat-shrinkable plastic film, etc. are used. Further, as the aluminum vapor-deposited film 12, a polypropylene film or the like having excellent aluminum vapor deposition properties is used.

In the case of paper or a plastic film unsuitable for aluminum vapor deposition, conventionally, an aluminum vapor-deposited film was bonded to it to form an aluminum vapor-deposited surface, but in the present invention, the plastic film l is Alternatively, by replacing plastic films that are unsuitable for vapor deposition, aluminum vapor deposition surfaces can be directly formed on these materials.

・Effects of the present invention As described above, the present invention provides an aluminum vapor-deposited film,
The punching process can be performed by pasting together a plastic film or paper coated with an adhesive in accordance with the printed design or characters, and then peeling off the two after the adhesive has hardened.

As a result, the following effects are obtained.

a. A film is printed and coated with adhesive using methods such as gravure printing, and then an aluminum vapor-deposited film is laminated onto this, and the film is peeled off after the adhesive has hardened, so the process is a series, and there is no need to move the film during the punching process or There is no need for a washing process, and the cost required for these steps is reduced.

b. - Since the punching process is performed simply by peeling off the bonded materials, the bonding and peeling can be performed automatically by known means, and the speed of the punching process is significantly improved.

Because punching is performed using C0 printing technology, the outlines of designs and letters are beautiful, and it is also possible to print extremely small letters, line punching, or aluminum vapor-deposited letters, which were impossible with conventional washing methods due to the lines flying off. You can form patterns.
