The following will be described in detail with reference to the accompanying drawings, preferred embodiments of the present invention water separation label.

The term "water separation label" described throughout this specification means a label capable of separating the label into the skin complex 10 by water, which is a concept including a sticker.

The present invention allows water to penetrate through the waterway, and when the water penetrates, the volume of the moisture absorbent increases, and the label is peeled off by itself.

As shown in Figures 1 to 3, the water separation label according to an embodiment of the present invention, the base sheet 110, and one side of the base sheet 110 [inner surface based on the figure shown] The adhesive layer 120 is formed, and the inner surface of the adhesive layer 120 attached to the skin adherend 10 (the surface adhered to the adherend 10) is formed with water on the adhesive layer 120 and the skin adherend 10. A water path 125 is formed to infiltrate into the base sheet 110 so as to penetrate therebetween, and the water path 125 crosses the adhesive layer 120 from one side of the horizontal direction orthogonal to the layer direction. It is formed by tapping, the water penetrates through the water path 125 between the skin complex 10 and the adhesive layer 120, the space between the adhesive layer 120 and the skin complex 10, the label is a skin complex ( 10) characterized in that peeled off.

The skin complex 10 may be, for example, a container, a package, or a household article made of a material such as a bottle, glass, plastic, metal (aluminum, iron, stainless steel, etc.), in particular, a recycled container, a recycled package, or a recycled product. Household goods are most suitable.

The base sheet 110 may be made of any one of paper, synthetic resin (PET, PP, PI, PVC, PE, etc.) and nonwoven fabric.

A print layer (not shown) may be formed on an outer surface of the base sheet 110.

As illustrated in FIGS. 2 and 3, the water path 125 may be formed in a grid-shaped pattern across the adhesive layer 120, but is not limited thereto and may be formed in various shapes of patterns. In any case, it belongs to the technical scope of the present invention.

As described above, the water path 125 is infiltrated in the horizontal direction of the adhesive layer 120, so that water penetrates easily between the adhesive layer 120 and the adherend 10.

The " water path 125 is formed across the horizontal direction of the adhesive layer 120 " means that the channel (from one end to the other end of the circumferential surface of the adhesive layer 120, as shown in Figs. channel through).

In the water separation label according to an embodiment of the present invention, the adhesive layer 120 is formed by mixing the adhesive and the water absorbent, and the adhesion of the skin 10 and the adhesive layer 120 through the water path 125 Water penetrates through the water path, and the water absorbent absorbs the water penetrated through the water path 125, and the volume of the water absorbent that absorbs the water increases, so that the space between the adhesive layer 120 and the skin deposit 10 is increased. Spaced apart, the label is separated from the skin complex 10 by being spaced apart between the adhesive layer 120 and the skin complex 10.

The adhesive layer 120 is formed by mixing an adhesive and a moisture absorbent.

For example, 100 parts by weight of the adhesive may be composed of 1 to 99 parts by weight of the moisture absorbent, but this is exemplary and the mixing ratio may be configured to vary for the following reasons.

The mixing ratio of the adhesive and the water absorbent varies depending on the type of the skin complex 10 and also depends on the temperature and humidity conditions of the environment in which the skin complex is used. For example, in a high temperature and high humidity environment, the mixing ratio of the water absorbent is decreased. In cold dry environments, the mixing ratio of the moisture absorbent will be high.

The adhesive may be, for example, an acrylic pressure sensitive adhesive, a silicone pressure sensitive adhesive or a rubber pressure sensitive adhesive, but is not limited thereto. In addition, the adhesive may be formed by selecting a known adhesive.

And in the case of the present invention, the adhesive is used in a concept including an adhesive.

In the water separation label according to an embodiment of the present invention, the moisture absorbent is SAP (Super Absorbent Polymer, Super Absorbent Resin) (Sa: Sa1, Sa2) is characterized in that.

The SAP (Sa) is very excellent in water absorption so that it can be peeled off in an early time.

The SAP (Sa) is generally defined as a superabsorbent polymer, a polymer exhibiting the phenomenon of fluid absorption due to introduction of hydrophilic groups in a three-dimensional network structure or a single chain structure through crosslinking between polymer chains.

The action peeled by the said SAP (Sa) is demonstrated concretely.

Of the SAP (Sa) mixed in the adhesive layer 120, only SAP (Sa1) on the surface of the adhesive layer 120 (inner surface attached to the adherend 10) acts on the peeling, and the SAP in the interior not near the surface. (Sa2) does not directly participate in peeling, which increases in volume due to water absorption.

That is, the SAP (Sa1) on the surface of the adhesive layer absorbs water to increase the volume, and the SAP (Sa1) on the bulky surface separates the surface of the adhesive layer 120 from the skin deposit 10, thereby. The label is peeled off.
