Abstract

PURPOSE:To provide a label having water resistance and capable of facilitating the peeling after sticking. CONSTITUTION:On the rear surface of a stretched film 1 produced by stretching a plastic film in a specific direction, adhesive layers 4 are formed at certain intervals along the parallel direction to the stretching direction. The area between the adhesive layers 4 is used as a nonadhesive area. The stuck state of the stretched film 1 to a product is maintained with the adhesive layers 4. Only by heating the stretched film 1 at the time of peeling, the nonadhesive area 5 is shrinked in the direction opposite to the stretching direction, so that the shrinked nonadhesive part is pulled to peel off only the adhesive layer 4 stuck to the product.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tack label on which information of an article is printed and affixed to the article, and more particularly to a tack label which can be easily peeled from the article and a peeling method thereof.

[0002]

2. Description of the Related Art A tack label on which the contents of the article and the article information such as the manufacturer or the destination of the article is printed is attached to the article. Taking the distribution of goods as an example, a plurality of paper packs of milk, juice and the like are collectively housed in a commutable container and delivered in units of the commutable container. In this case, the number of the returnable container is printed in advance on the tack label, and the tack label is attached to the returnable container to identify the item at the time of delivery. This tack label is made of paper, and the adhesive surface on the back side is peeled off from the backing sheet and pasted on the container.

[0003]

However, the conventional tack label, once attached to an article, cannot be easily peeled off again. That is, the label itself is paper, and the entire back surface of the label is an adhesive surface, so that there is a defect that the label portion remains on the article when the label is peeled off. In this case, the label is soaked in water and scraped off, which is troublesome. As described above, the conventional tack label is not suitable for the one in which the peeling and sticking of the tack label are repeated like a returnable container. Further, among these returnable containers, there is a container which is kept in a refrigerating state at all times for containing milk, juice and the like and placed in an atmosphere with a lot of water. The tack label attached to this returnable container is required to have water resistance.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a tack label which has water resistance and can be easily peeled off after pasting, and the tack label. It is an object of the present invention to provide a tack label peeling method that can be easily peeled off after application.

[0005]

In order to achieve the above object, the tack label of the present invention comprises a thermoplastic plastic film 1 formed by stretching in at least a certain direction.
On the back surface of the adhesive layer 4, which is formed continuously or intermittently at intervals in the direction parallel to the stretching direction, a non-adhesive portion 5 formed between the adhesive layers in a plurality of rows, and on the adhesive layer. It is characterized in that it further comprises a release paper 6 formed.

Further, an adhesive layer 4 formed continuously or intermittently on the back surface of the thermoplastic plastic film 1 formed by stretching in at least a certain direction at intervals in the direction parallel to the stretching direction, and a plurality of rows. The tack label including the non-adhesive portion 5 formed between the adhesive layers is characterized by being attached and then peeled by a peeling method of heating the non-adhesive portion 5 to shrink along the stretching direction.

[0007]

The tack label made of the stretched plastic film 1 is provided on the release paper 6 and is removable from the release paper 6. This tack label has a stretched film 1 on the back.
Adhesive layers 4 are formed continuously or intermittently at intervals in the direction parallel to the stretching direction, and non-adhesive portions 5 are formed between the adhesive layers 4. As a result, the tack label after peeling from the release paper 6 is attached to the article only by the adhesive layer 4 at predetermined intervals, and can be peeled from the non-adhesive portion 5 at the time of peeling. And by heating this tack label at the time of peeling, this tack label stretched in a certain direction,
The non-adhesive part 5 contracts and curls, and can be easily peeled from this part.

[0008]

1 is a plan view showing an embodiment of a tack label of the present invention. The substrate of this tack label is made of a longitudinal uniaxially stretched film 1 made of plastic. The stretched film 1 is formed in the axial direction (vertical direction in the figure) during molding.
PVC (vinyl chloride), PET (polyester), PP that are thermoplastic materials that are formed by stretching
Any resin such as (polypropylene) and PS (polystyrene) that is normally used for a stretched film may be used.

As shown in the side sectional view of FIG. 2, a white or black coating layer 2 is formed on the entire back surface of the stretched film 1.
Is formed. The coating layer 2 may be provided on the front surface of the stretched film 1 as shown in FIG. The printing layer 3 on the front surface of the stretched film 1 can be easily recognized by the coating layer 2. The print body 3 is composed of characters, figures, symbol codes and the like.

An adhesive layer 4 is provided on the back surface of the stretched film 1 at predetermined intervals in a direction parallel to the stretching direction. In the illustrated example, adhesive layers 4 each having a predetermined width are provided at both ends in parallel with the stretching direction, and non-adhesive portions 5 having a predetermined width are provided between the adhesive layers 4.
In the drawings, the adhesive layer 4 is shown by a hatched portion for easy visual recognition.

The stretched film 1, the coating layer 2,
The tack label 10 including the printed body 3, the adhesive layer 4, and the non-adhesive portion 5 is provided on the release paper 6. The release paper 6 has a predetermined length and is provided with a plurality of tack labels 10 in advance. Further, this release paper 6 is formed in a roll shape and can be mounted on a label issuing machine. Tack label 10
On the front surface of the stretched film 1, a printing unit such as a label printing machine prints to form a printing body 3. The tack label 10 after printing can be peeled from the release paper 6 and attached to an article. At the time of sticking to an article, the tack label 10 holds the adhesive layer 4 portion stuck to the article. Further, since the stretched film 1 forming the base of the tack label 10 is formed of a plastic film, it has water resistance.

When the tack label 10 is peeled from the article to which the tack label 10 is attached, the tack label 10 is heated by a heating means. Heating is 80
By blowing steam or hot air more than a degree or seeping into hot water. Since the stretched film 1 of the tack label 10 is stretched and formed in a predetermined direction and has thermoplasticity, the stretched film 1 has the property of shrinking in the direction opposite to the stretching direction by heating. This shrinkage ratio is preferably 30% or more after heating at 100 ° C. for 1 minute in the vertical direction.

4 and 5 are a plan view and a side view, respectively, showing a state of the tack label 10 during heating. As shown in the drawing, the stretched film 1 in the non-adhesive portion 5 not adhered to the article is curled due to shrinkage by heating. Therefore, the tack label 10 can be peeled from the article by holding the curled portion 5a by hand. When peeling,
Only the adhesive layer 4 portion is peeled off, and it can be peeled off easily. At the time of peeling, after the tack label 10 is heated, wind pressure or water pressure may be applied to the tack label 10 to blow off the tack label 10.

6 and 7 show modified examples of the tack label 10, respectively. As shown in FIG. 7, the adhesive layer 4 is arranged in three rows in parallel with the extending direction (both ends and central portion). ), Or as shown in FIG. 7, a plurality of rows may be provided as long as they are parallel to the stretching direction. The ratio of the adhesive layer 4 to the total area of the tack label 10 is preferably 1/2 or less of the area of the tack label 10 in order to facilitate peeling. Further, the adhesive layer 4 may be provided continuously in a direction parallel to the stretching direction, or may be provided intermittently as shown in FIG.

FIG. 9 is a flow chart showing a series of steps from the manufacture of the tack label to the sticking to and peeling from the article. The tack label 10 is manufactured in the parts from SP1 to SP4, and a plurality of tack labels 10 are provided on the release paper 6 in the above step and are ready for use. After the desired printing (SP5) corresponding to the article is made on the tack label 10, the sticking to the article is SP6.
Performed at SP7. And from the article, tack label 1
When 0 is peeled, it can be peeled through the steps of SP8 to SP11.

The tack label 10 can be attached to the article itself, or can be attached to a case for storing the article, a returnable container or the like. Further, the tack label 10 of the present invention is particularly effective for an article such as a returnable container where sticking and peeling are frequently repeated, and the above-described operational effects can be obtained.

In each of the above examples, a longitudinal uniaxially stretched film is used as the base of the stretched film 1, but
Alternatively, a biaxially stretched film may be used. This biaxially stretched film is also formed by stretching in a direction orthogonal to the stretching direction of the uniaxially stretched film. In the tack label using this biaxially stretched film, by providing the adhesive layer 4 along at least one stretching direction, it is possible to obtain the same effect as that of the above-mentioned embodiment.

[0018]

The tack label of the present invention comprises a plastic film stretched and formed in a certain direction, and an adhesive layer is continuously or intermittently formed on the back surface thereof at intervals in the direction parallel to the stretching direction. Since the non-adhesive portion is formed between the adhesive layers, the tack label after being peeled off from the release paper is attached to the article only with the adhesive layers at predetermined intervals. Therefore, a part of the label does not remain on the article at the time of peeling, and the label can be easily peeled from the non-bonded portion.

Further, by heating the tack label at the time of peeling, the non-adhesive portion shrinks and curls in the direction opposite to the stretching direction, and the portion can be easily peeled from this portion. As described above, the tack label of the present invention can obtain a marked effect for an article in which sticking and peeling are repeated.
