Description

[Detailed explanation of the idea] Industrial applications The present invention relates to packaging materials.

BACKGROUND ART Conventionally, packaging materials such as shrinkable synthetic resins coated with metal vapor deposition and shrinkable synthetic resin films have been known, but each of these has often been used alone.

Problems that the invention aims to solve As mentioned above, shrinkable synthetic resin films coated with metal vapor deposition have been known as shrink wrapping materials with a metallic luster. It is difficult to do so, and the printed pattern often deviates from the predetermined position, and there are also drawbacks such as the metal-deposited part becoming white due to the heat during heat shrinkage.

On the other hand, although it is not shrinkable, it is also known that metal foil is drawn and used as cap seals for wine, etc. However, not only is the drawing process time-consuming, but it also causes "wrinkles" that occur during the drawing process. There were drawbacks such as the printing of letters, designs, etc. being difficult to read due to ``Takure'' etc.

Means to solve problems Next, the configuration of the present invention will be explained.

A metal vapor deposition layer 3 is provided on at least one surface of the shrinkable synthetic resin film 1 and the non-shrinkable film 2,
Both films 1 and 2 are bonded together using an adhesive layer 4 which is formed in an appropriate pattern and has a shrinkage area removed.

Function The present invention has the above-mentioned configuration and is used in the same way as conventional packaging materials, but in this invention, the shrinkage area where the adhesive layer 4 is formed in an appropriate pattern is removed. Since the shrinkable synthetic resin film 1, which has a metal vapor deposited layer 3 on at least one surface, and the non-shrinkable film 2 are laminated together in a state in which the film is shrunk and packaged, the fourth As shown in the figure, the non-shrinkable synthetic resin film 2 and the metal vapor deposited layer 3 cause "wrinkles" in the areas where the adhesive layer 4 was previously removed to allow for shrinkage, and the shrinkable film 1 shrinks, resulting in a metallic luster. It is possible to provide a certain good printing effect, and it is possible to provide shrinkage performance even though the non-shrinkable film 2 is used.

Embodiments Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows that a metal vapor deposition layer 3 is provided on one surface of a non-shrinkable film 2, and then a shrinkable synthetic resin film 1 is pasted with an adhesive layer 4 from which shrinkage areas formed in an appropriate pattern are removed. metal vapor deposition layer 3
may be provided on the other surface of the non-shrinkable film 2, but
In this case, it is advisable to provide a protective layer. Examples of the non-shrinkable film 2 include paper, synthetic paper, and synthetic resin film.

FIG. 2 shows a modification of the non-shrinkable film 2 and the shrinkable synthetic resin film 1 shown in FIG. 1, in which a metal vapor deposited layer 3 is provided on the shrinkable synthetic resin film 1. It is also possible to provide the metal vapor deposited layer 3 on the other surface of the shrinkable synthetic resin film 1, but it is of course preferable to provide a protective layer in this case as well.

FIG. 3 shows a metal vapor deposited layer 3 on at least one surface of a shrinkable synthetic resin film 1 and a non-shrinkable film 2.
, the shrinkable synthetic resin film 1 has a larger area than the non-shrinkable film 2, and when the shrinkable synthetic resin film 1 constitutes the independent portion 5, the adhesive layer 4 may be provided anywhere; It may be provided on the entire surface except for the portion 5 or may be provided partially. Further, when a cylindrical body is formed in advance and packaged, an adhesive or a pressure-sensitive adhesive or the like may be applied to the individual portion 5.

When the metal vapor deposition layer 3 is on the outside, it is preferable to provide a layer to protect the layer 3.

Note that aluminum can be considered as a suitable example of the vapor-deposited metal.

Effects of the invention Since the present invention has the above-mentioned configuration, a shrinkable packaging material with a metallic luster and good printing effect can be obtained.
In addition, even though a non-shrinkable film is used, it can still have shrinkage properties, so there is no need for drawing process like with metal foil, and the printing effect is inhibited by "wrinkles" and "tackle". If the film is exposed to severe shrinkage conditions or harsh usage conditions, it will be sufficient to form a metal vapor deposited layer between the shrinkable synthetic resin film and the non-shrinkable film, and it will be extremely protected without causing any risk of whitening. It has a remarkable effect.
