The ink scraping layer (22) is formed of a treated surface ink (22a) having poor adhesive compatibility with the non-treated surface ink (23a).

The film bag with the bag mouth binding tape of the present invention has a weak adhesive force because an easily peelable adhesive layer is formed on the back surface of the tape body of the bag mouth binding tape. Even if it is attached to the outer surface of the film bag, it can be easily peeled off when necessary and does not adhere to the hand during use.

Therefore, for example, if you want to subdivide what you want to use on the road or where you want to go, or if you want to subdivide food, or if you want to store refrigerated or frozen foods, remove them from the outer surface of the film bag. If it is wrapped around the mouth of the film bag using the tape for binding the bag mouth, the mouth of the film bag can be easily tied and sealed.

In particular, since the ink layer for scraping is formed on the surface of the tape body, this ink layer for scraping is made of hard, pointed tips such as bamboo skewers, chopsticks, toothpicks, human toes, forks, hairpins, etc. By scraping with an object, characters and the like can be easily drawn and used conveniently.

Conventionally, when gravure printing is applied to plastic film, the film surface is subjected to mechanical treatment, chemical treatment, physicochemical treatment to ensure that the ink used for printing adheres to the film surface. In addition to forming a rough surface, it has been widely used to use ink having excellent adhesive compatibility with the treated surface (ink for treated surface).

On the other hand, when gravure printing is performed on a non-processed surface that does not form a fine uneven surface on a plastic film, the adhesive compatibility with the non-processed surface is ensured so that the ink used for the printing adheres securely to the film surface. Use excellent inks (non-treated surface inks).

Accordingly, in claim 1 of the present invention, the surface of the tape body (20) is formed on the non-treated surface (20a), and the treated surface ink (22a) having poor adhesion compatibility with the non-treated surface (20a) is used. Since the ink layer (22) for scraping was formed by using this, the adhesive force of the ink for processing surface (22a) to the non-processing surface (20a) was weakened, and the scraping using the ink for processing surface (22a) was performed. The ink layer (22) can be easily scraped off.

According to claim 2 of the present invention, the surface of the tape body (20) is formed on the non-treated surface (20a), and the non-treated surface ink (23a) having excellent adhesive compatibility with the non-treated surface (20a). ) To form an intermediate ink layer (23), and further adhere to the non-treated surface ink (23a) forming the intermediate ink layer (23) on the intermediate ink layer (23). Since the scraping ink layer (22) was formed using the inferior surface treatment ink (22a), the adhesion of the treatment surface ink (22a) to the non-treatment surface ink (23a) was weakened. The scraping ink layer (22) using the treated surface ink (22a) can be easily scraped off.

It is also possible to form the surface of the tape body on the treated surface and form a scraping ink layer using non-treated surface ink that has poor adhesion compatibility with the treated surface.
Alternatively, the surface of the tape body is formed on the treated surface, an intermediate ink layer is formed using the treated surface ink having excellent adhesive compatibility with the treated surface, and the intermediate ink layer is further formed on the intermediate ink layer. It is also possible to form a scraping ink layer using a non-treated surface ink that has poor adhesion compatibility with the treated surface ink forming the ink layer.

However, in Claims 1 and 2 of the present invention, since the surface of the tape body (20) is formed on the non-treated surface (20a), the surface of the tape body (20) is subjected to mechanical treatment, physicochemical treatment, There is no need for chemical treatment, which is advantageous in terms of manufacturing equipment and manufacturing costs.

In addition, the said mechanical treatment mentioned as a processing method of the film surface forms a fine uneven surface on the surface by, for example, hitting the surface with sand or polishing it with a metal brush or sandpaper.
The chemical treatment is to form a fine irregular surface on the surface by applying a chemical to the surface to cause a chemical change.
The physicochemical treatment uses a physical change or chemical change caused by corona discharge, plasma discharge, flame treatment, ultraviolet treatment, or the like to form a fine uneven surface on the surface, and corona discharge is generally used.

It is a front view which shows the film bag with a tape for bag mouth binding of an Example. It is a figure which shows the state which tied the opening | mouth part of the film bag with the bag mouth binding tape. It is a schematic cross section of the bag mouth binding tape corresponding to claim 1. It is a schematic cross section of the bag mouth bundling tape corresponding to claim 2.

As shown in FIG. 1, the film bag with the bag mouth binding tape of the present embodiment is attached (adhesion) to the outer surface of the film bag 1 with the bag mouth binding tape 2 by an adhesive layer 21 having an easily peelable back surface. It has been done.
The film bag 1 can be formed as a food storage bag, a portable small bag, or other storage bag.
The film bag 1 of the embodiment is formed in a bag body in which an opening 10 is formed at the upper end, the bottom is closed by a seal 11, and gussets 12 are folded on both sides. The size, the presence or absence of a gusset, the material of the film Etc. are appropriate.

The bag mouth binding tape 2 is formed of a plastic film such as a polyethylene film, and a tape main body 20 having a length substantially the same as the length of the film bag 1 is formed. An adhesive layer 21 in which the agent is continuously applied in a strip shape from the upper end to the lower end is formed.

As a structure for forming the adhesive layer 21 on the back surface of the tape body 20, the adhesive layer 21 is formed narrower than the tape body 20 along one side of the tape body 20, and the adhesive layer 21 is formed intermittently. The adhesive layer 21 may be formed on a part of the back surface of the tape body 20 by forming the adhesive layer 21 into a continuous waveform or by forming the adhesive layer 21 one by one up and down.

The adhesive layer 21 may be formed on almost the entire surface of the tape body 20, but in this case, a non-adhesive layer that serves as a finger grip when the bag mouth binding tape 2 is peeled off on a part of the back surface. The part is preferably formed.

Further, the pressure-sensitive adhesive layer 21 is preferably formed of a pressure-sensitive adhesive having re-adhesiveness in addition to easy releasability from the viewpoint that it can be repeatedly peeled off and used when re-binding. .

Further, a scraping ink layer 22 is formed on the surface of the tape body 20.
In this case, in the example shown in FIG. 3 (example corresponding to claim 1), the surface of the tape body 20 is formed on the non-processed surface 20a not subjected to the surface treatment for gravure printing, and the non-processed surface 20a is formed thereon. The scraping ink layer 22 is formed by using the treatment surface ink 22a having poor adhesion compatibility with the treatment surface 20a.

That is, the surface of the tape body 20 is formed on the non-treated surface 20a, and the scraped ink layer 22 is formed using the treated surface ink 22a having poor adhesion compatibility with the non-treated surface 20a.
Thereby, since the adhesive force with respect to the non-processed surface 20a of the ink 22a for process surfaces becomes weak, the ink layer 22 for scraping can be scraped off easily.
And since the lower non-processed surface 20a is exposed by scraping off this ink layer 22 for scraping, a character etc. can be drawn.

Further, in the example shown in FIG. 4 (example corresponding to claim 2), the surface of the tape body 20 is formed on a non-processed surface 20a not subjected to surface treatment for gravure printing, and the non-process is formed thereon. The intermediate ink layer 23 is formed with the non-processed surface ink 23a having excellent adhesive compatibility with the surface 20a, and the adhesive compatibility is inferior to the non-processed surface ink 23a used in the intermediate ink layer 23 thereon. The scraping ink layer 22 is formed by using the surface ink 22a.

That is, the surface of the tape body 20 is formed on the non-treated surface 20a, and the intermediate ink layer 23 is formed using the non-treated surface ink 23a having excellent adhesive compatibility with the non-treated surface 20a. On the ink layer 23, a scraping ink layer 22 is formed by using a treated surface ink 22 a that has poor adhesion compatibility with the non-treated surface ink 23 a that forms the intermediate ink layer 23.
As a result, the adhesion force of the non-treatment surface ink 23a to the non-treatment surface 20a is increased, while the adhesion force of the treatment surface ink 22a to the non-treatment surface ink 23a is weakened, so that the scraping ink layer 22 can be easily formed. Can be scraped off.
Since the lower intermediate ink layer 23 is exposed by scraping the scraping ink layer 22, characters and the like can be drawn.

In this embodiment, the tape body 20 is formed of a polyethylene resin film, and, for example, “Polyeticking” (trademark) manufactured by Toyo Ink Manufacturing Co., Ltd. is used as the treatment surface ink 22a for forming the scraping ink layer 22. In addition, as the non-process surface ink 23 a for forming the intermediate ink layer 23, for example, “COSMO TONE” (trademark) manufactured by Toyo Ink Manufacturing Co., Ltd. is used.

The gravure printing ink contains a resin, a solvent, a colorant, and an auxiliary agent, and among these, the auxiliary agent is an additive for improving printing stability and adhesiveness.
And the ink for non-treated surface is set with the kind of ingredients and the blending ratio necessary to enhance the adhesive compatibility with the non-treated surface, and the kind and composition of ingredients necessary to enhance the adhesive compatibility with the treated surface. What set the ratio is treated surface ink.

As shown in FIG. 1, the film bag with the bag mouth bundling tape of this example is one in which the bag mouth bundling tape 2 is attached (adhered) to the outer surface of the film bag 1 by the adhesive layer 21 on the back surface. Sometimes, the bag mouth binding tape 2 is peeled off, and the bag bag binding tape 2 is wrapped around the mouth of the film bag 1 as shown in FIG. do.

Then, when recording the name, date and time of the stored contents, since the scraping ink layer 22 is formed on the surface of the bag mouth binding tape 2, the scraping ink layer 22 is, for example, Characters can be easily drawn by scraping with a hard object such as a bamboo skewer, chopsticks, toothpick, human toe, fork or hairpin.
