Description

Structure of Water-Solution Label

The present invention relates to an alkali or water-soluble dissociable double-sided tape type dissociable label, and more specifically, a general label used in a general waybill or a box for adhesion to a part to be adhered once. If the label is removed, it is difficult to remove the label from the surface of the adherend because the pulp is not easily recycled or detached from the adherend, and the label adhesive remains on the surface of the adherend. In order to improve the problems, such as difficult to remove, by dissolving in water or soapy water so that the label is easily separated, to ensure the recyclability of the pulp and to facilitate the separation of the label from the surface of the adherend.

Invoice labels, which are generally used for logistical processing, include a variety of preliminary information on the invoice in addition to the various preliminary information recorded on the invoice. The need for highly functional materials and functional paper has increased to make marking and identification as convenient and easy as possible.

For example, an invoice in which several sheets of paper are bundled together and simultaneously print the same contents requires four or more multilayered structures as shown in FIG.

Here, looking at the sheet of invoice, separately from the printing surface 10, there is a separate paper-printing surface (11), which is indicated in the logistics delivery / receipt confirmation process, the issuer storage paper (12), the supplier storage paper (13), etc. There is a separate sheet. Such normal invoices are not easily torn, poor in durability, not suitable for high-performance printing, and inconvenient to use, and have been gradually replaced by label invoices that directly attach invoices to logistics as shown in FIG.

Representative structure of the label invoice is made to transport the logistics by attaching the invoice directly to the logistics (goods), as shown in Figure 2, has been presented in a variety of structures.

In general, there is an adhesive part 16 for adhering the invoice 15 having the printing surface 14 formed in the logistics, and has a confirmation sheet to be delivered to the final buyer separately from the printing surface 14, where the adhesive layer Silver acrylic emulsion type permanent (Acrylic Emulsion Type Permanent) or acrylic emulsion release bubble (Acrylic Emulsion Type Removable) adhesive was used.

Such an invoice of the label does not fall off due to the adhesive force when the adhesive 16 to which the adhesive is applied is attached to the adherend 17 such as a box and a container as shown in FIG. 3. Accordingly, there is a problem that the label is not easily removed along with a problem that the recyclability of the paper pulp constituting the label invoice is not guaranteed.

Similarly, Fig. 4 shows a case in which the adherend 17 has a label 18 attached to a PET bottle which is a plastic container, and the label 18 attached to the container has a printing surface 19 on its surface. The back side uses a label 18 made of an adhesive part 20 to which an adhesive is applied.

As shown in FIG. 4, the adherend 17 is a plastic container, and the adhesion state and the removal state of the label 18 used for the purpose of displaying a product on the surface thereof are as follows.

When the label 18 is attached to the surface of the container, the release paper layer (not shown) attached to the adhesive portion 20 is simply removed to determine the surface to be deposited in the state where the adhesive portion 20 is exposed, and the adhesive portion 20 is left as it is. When the adhesive is adhered to the surface, the label 18 is adhered to the surface of the adherend by the adhesive force of the adhesive applied to the adhesive part 20.

The adhesion state to the plastic container is maintained by the adhesive force of the adhesive, which is usually adhered using a high strength adhesive in order not to be relieved. PET containers, on the other hand, are materials that are highly recyclable. When recycling them, the labels on the surface of the containers must be removed and only the containers will be recycled.

In order to remove the label easily, the label adhesive can be easily removed from the surface of the container. However, since the high-strength adhesive is used to prevent the label from falling off during use, the label is not easily removed from the surface of the container. There is this.

In addition, since the printed surface, which is the surface layer of the label, is made of expensive pulp, this part itself is highly recyclable, and there is a problem such that it is not easily peeled off by the adhesive during the removal step from the surface of the container and is easily torn. It is rarely recycled.

Therefore, an object of the present invention is to ensure the recyclability of the paper pulp constituting the label by making it possible to easily separate the label adhering to the adherend from the adherend.

Another object of the present invention is to make it easy and simple to remove the label from the adherend by making the label adhering to the adherend easily detachable from the adherend.

Another object of the present invention is to improve the recyclability of recyclable adherends, such as packaging containers to be adhered by simplifying the label removal operation for recyclability, such as packaging containers to be the adherend of the label.

The dissociable label structure of the present invention for achieving the above object includes a printing surface made of paper constituting the surface of the label, an adhesive layer applied to the back surface of the printing surface to adhere the printing surface to the adhered surface, and the adhesive layer. In the label formed by maintaining the shape of the label attached to the lower portion and sequentially bonding the release paper separated from the adhesive layer,

A separation label having a printing layer for labeling capable of printing on the surface of paper;

A dissociable adhesive layer for dissociating the separating label into a water-soluble and alkaline component to separate the separating label from the adhesive layer;

The dissociable adhesive layer is characterized by consisting of a release paper bonded to the dissociable adhesive layer so that it can be dissociated into water-soluble and alkaline components.

By dissociating the label into water-soluble or alkaline components, it is possible to guarantee the recyclability of the pulp and dissociate into water-soluble and alkaline components. If you put it in the tank, you can separate the label from the surface of the container, so you can collect and recycle the container directly as the container and paper as the paper without any additional work to remove the label.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 5 and 6.

5 is a cross-sectional view of a dissociable label according to the present invention. 6 is a cross-sectional view of a dissociable label according to another embodiment of the present invention.

The dissociable label according to the present invention, as shown in Figure 5, basically the printing surface of the paper constituting the surface of the label, the adhesive layer applied to the back surface of the printing surface to adhere the printing surface to the adhered surface, and the adhesive layer The label is adhered to the lower portion of the label to maintain the shape of the label and is made by sequentially bonding the release paper separated from the adhesive layer.

Specifically, it consists of the separation label 30 provided with the printing layer 32 for labels which can print on the surface of the paper 31.

In addition, the separation label 30 is provided with a dissociable adhesive layer 40 for dissociating the separation label 30 from the adhesive layer 41 by dissociating it into a water-soluble and alkaline component.

In addition, the dissociable adhesive layer 40 is composed of a release paper 50 bonded to the dissociable adhesive layer 40 to be dissociated with a water-soluble and alkaline component.

6 is another embodiment of the present invention, in which the dissociable adhesive layer 40 is separated from the separation label 30 made of the label printing layer 32 and the paper 31. The adhesive layer 42 and the printing layer ( 43), the paper 44, the dissociable adhesive coating 45 is configured in this order. Here, the release paper 50 was composed of a silicone coating 51, a dissociable adhesive coating 52 and a paper 53 layer in sequence.

Effects of the present invention configured as described above are as follows.

Dissociative label according to the present invention, first, when the release paper 50 is removed from the dissociable adhesive layer 40, the bottom surface of the dissociable adhesive layer 40 is exposed and the surface is attached to the surface of the adherend, dissociable adhesive 40 It is adhered to the adherend by the inherent adhesive force of, so that it does not fall well. In this state, the label printing layer 32 is realized by the paper 31 on the surface, and the label printing layer 32 including the paper 31 by the adhesive layer 41 of the dissociable adhesive layer 40. ) Is attached to the adherend.

On the other hand, if you want to remove the remaining portion other than the dissociable adhesive layer 40, that is, the label printing layer 32 including the paper 31, from the adherend, dissociate even if you hold the end of the paper 31 by hand. The adhesive force of the adhesive layer 40 does not easily fall off or tear off even if it falls off, and the remaining material of the adhesive layer 41 and the like remain on the surface of the adherend as it is.

Here, if the label printing layer 32 including the paper 31 can be separated in a limited manner, and in the process, the dissociable adhesive can also be removed from the adherend surface, this is most ideally removing the label while leaving no adhesive. It's a way to do it. The present invention is conceived here. That is, the label has a separation label 30 structure that can be separated from the adhesive layer, and in order to make this possible, by using the dissociable adhesive layer 40, the resulting label is brought into contact with an alkaline or water-soluble component. As the separation label 30 of the label is separated from the adherend, the adhesive that adheres to the adherend is also decomposed by the decomposition action, and the adhesive removal work on the adherend is also unnecessary.

Here, the separation label 30 is separated by dissociation in water-soluble and alkaline components. This is separated by configuring the adhesive layer with the dissociable adhesive layer 40.

The adhesive of the dissociable adhesive layer 40 adhering the separation label 30 has a property that can be easily dissolved by weak alkali, soapy water or hot water (70 ± 5 ° C.).

In addition, even if a small amount of adhesive is transferred to the adhesive surface, it is easily cleaned and removed by weak alkali (PH 11 ± 0.5) or hot-water rather than an organic solvent, and is removed without damaging the surface of the adherend.

In addition, such a separation label 30 may be used for a suitable purpose for both the tape and protection for special electronics when the static electricity is not generated.

In addition, the separation label 30 may be suitably adhered to glass, iron plate (non-ferrous metal), plastic and painted surface, and in this case, since there is little coating film transfer on the adherend, various automobile, electronic and thin film liquid crystal display devices, It is convenient and suitable for use in containers, boxes and other beauty products for both ends.

In addition, the dissociable label of the present invention has excellent initial and late adhesive strength, excellent heat resistance (actual temperature above 150 ° C) and no change over time because it is easily reacted with surface moisture when attached to various products due to the hydrophilicity of the adhesive coating film. Has

As in the embodiments described above, the dissociable label according to the present invention can be easily separated from the adherend by being decomposed from the adherend with an alkaline or water-soluble component, thereby ensuring the recyclability of the pulp on the label. There is. In addition, when the label attached to the adhered surface is removed, there is an effect that it is possible to provide an eco-friendly and economical label by disassembling the label and adhesive from the adhered surface only by disassembling without a separate surface removal work.
