Abstract

(57) [Summary] [Purpose] To provide an adhesive film for sealing which is attached to the surface of a product, in which the air layer generated when the adhesive film is attached to the surface of the product can be easily and quickly degassed to the outside. The purpose is to [Structure] In a pressure-sensitive adhesive film for sealing in which a pressure-sensitive adhesive layer 3 is formed on the back surface of the film 2, degassing pinholes 5 penetrating the film 2 and the pressure-sensitive adhesive layer 3 are provided at a plurality of locations.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adhesive film for a seal, which is affixed to the surface of a product and displays handling precautions and product specifications.

[0002]

[Prior art]

 For example, a label indicating the handling precautions and product specifications is attached to the surface of the product, but it is usually difficult to peel off the adhesive film for sealing with the adhesive applied to the back surface of the film. It is used a lot.

When this kind of adhesive film for sealing is attached to a predetermined portion of the product surface, air is often present between the product surface and the film, and in such a case, the adhesion of the film is deteriorated. At the same time, the appearance and design deteriorate, and there is a problem in that the display function cannot be sufficiently achieved because it is not legible when fine characters are printed, especially in handling precautions.

Conventionally, when an air layer is interposed between the product surface and the film, it is troublesome that the film surface is strongly stroked with a jig such as a spatula to expel air from the end surface of the film to the outside. I needed deaeration work.

[0005]

[Problems to be solved by the device]

 In this way, the conventional adhesive film for seals is printed with the handling precautions and product specifications of the product and fulfills a predetermined display function.However, when the film is attached to the surface of the product, It must be carefully attached so that no air layer is present between the surface and the film, and if an air layer were to be present, there was a problem that a troublesome degassing operation was required.

The present invention has been made in view of the above circumstances, and the present invention is an adhesive film for a seal which is attached to the surface of a product. Since the air layer between the product and the product surface can be easily removed to the outside, an extremely practical adhesive film for sealing that can be easily attached to the product surface and degassed when an air layer is present The purpose is to do.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a pressure-sensitive adhesive layer on the back surface of a film, and in a pressure-sensitive adhesive film for a seal, which is attached to an arbitrary portion of a product through this pressure-sensitive adhesive, It is characterized in that a plurality of degassing pinholes are formed through the adhesive layer.

[0008]

[Action]

 As is clear from the above configuration, when an air layer is present between the film and the product surface when the film is attached to the product surface, pressing the film surface will set it in multiple locations. Since the air can be quickly removed to the outside through the existing degassing pinhole, the degassing operation of the internal air layer can be easily performed.

Further, since the deaeration work can be performed easily, the work of attaching the film to the product surface can be performed relatively roughly.

[0010]

【Example】

 Hereinafter, embodiments of the adhesive film for sealing according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view showing a state in which the adhesive film for sealing according to the present invention is attached to the surface of a product, and FIG. 2 is a sectional view showing the action of the adhesive film for sealing according to the present invention.

The adhesive film 1 for sealing according to the present invention has an adhesive layer 3 of acrylic adhesive or the like formed on the back surface of a film 2 such as a polyester film, and the surface of the film 2 has a product model number, Precautions for handling, product specifications, etc. are printed, and the product can achieve a predetermined display function by being attached to a predetermined place of the product 4 via the adhesive layer 3.

By the way, the adhesive pressure-sensitive adhesive film 1 according to the present invention is characterized in that a plurality of degassing pinholes 5 penetrating the film 2 and the adhesive layer 3 are provided.

In this embodiment, deaeration pinholes 5 having a diameter of 0.5 mm are opened at 9 positions at intervals of 30 mm.

Therefore, when the adhesive film 1 for sealing according to the present invention is attached to the surface of the product 4, and the air layer 6 is interposed between the surface of the product 4 and the adhesive film 1 for sealing, as shown in FIG. In addition, by pressing the surface of the film 1 toward the pinhole 5, the intervening air can be easily and quickly discharged to the outside through the degassing pinhole 5, and the surface of the adhesive film 1 for seal is The flat state can be maintained, good adhesion and appearance can be obtained, and the desired display function can be effectively achieved.

[0016]

[Effect of device]

 As explained above, the adhesive film for sealing according to the present invention has a plurality of degassing pinholes penetrating the film and the adhesive layer at a plurality of positions so that when the adhesive film for sealing is attached to the surface of the product, Air remaining between the surface and the film can be easily and quickly removed to the outside through the degassing pinholes provided at a plurality of locations, which has the effect of significantly improving the workability in degassing work.

Further, since deaeration work is conventionally troublesome, a careful sticking work is required for sticking the film, but the adhesive film for sealing according to the present invention makes the degassing work extremely easy. The film sticking work may be performed relatively roughly, which has the effect of improving the film sticking work efficiency as a whole.
