In the case of the re-adhesive label sheet paper through the differentiation of cohesive force for each stack according to the present invention, as shown in FIG. 1, it is attached to the surface of a portion accommodating contents such as a packaging container 1 or a packaging case (not shown). After that, this is a technical idea for a laminated structure of a label sheet that can be re-adhesive so that it can be opened and closed in an attached state.

For example, the packaging container 1 to which the re-adhesive label sheet paper through the differentiation of the cohesive force for each stack according to the present invention can be mainly applied is taken as an example, and the packaging container 1 has a meaning as an adherend, and the opening and closing thereof is required. Invention re-adhesion is made arbitrarily and selectively.

In the case of the re-adhesive label sheet paper through differential cohesiveness for each stack according to the present invention, as shown in FIG. 2, a base layer (100), a tension covering layer (200), and a tension layer , 300).

First, in the case of the base layer 100, as constituting the main body of the re-adhesive label sheet paper through the differentiation of cohesive force for each stack according to the present invention, the handle of the part that allows the user to open and close by hand in FIG. The opening and closing part is in charge.

The base layer 100 may be made of a commonly used material such as PET or PP, and there is no limitation on the type of the material.

In the case of the base layer 100, a portion of the lower surface thereof is attached to the surface of the packaging container 1, and the remainder of the lower surface is provided to open and close the outlet (not shown) of the packaging container 1.

In the above-described base layer 100, a part of the lower surface of the base layer 100 must be firmly attached to the surface of the packaging container 1, and it is important that the degree of such attachment is greater than the degree to which the remaining lower surface is re-adhesive.

When a part of the lower surface of the base layer 100 is firmly attached to the surface of the packaging container 1, the degree of adhesion may be sufficient, but it may be adhered and fixed.

As described above, the base layer 100 removes the remainder from the surface of the packaging container 1 in a state held by the user by hand, or performs an operation to cover the outlet of the packaging container 1 with the remainder. Since it is repeated throughout, the bent, pulled, or folded state may be repeatedly performed, and thus, the base layer 100 may be stretched due to material characteristics.

For this reason, the base layer 100 does not exist alone, and the tension covering layer 200 is provided on the lower surface of the base layer 100.

The tension covering layer 200 serves to coat the lower surface of the base layer 100, and the tension covering layer 200 is a layer coated with a material having a surface tension greater than the surface tension of the base layer 100 Means.

Due to this, the tension covering layer 200 generates resistance against the phenomenon of stretching of the base layer 100 from the lower surface of the base layer 100, bending when bending, and folding when folding, and such stretching phenomenon , Bending phenomenon, and folding shape are minimized.

In the case of the tension covering layer 200, the numerical significance of the function according to its properties will be described later.

In the case of the tension layer 300, the structure is provided on the lower surface of the tension covering layer 200 while being under the rest of the base layer 100.

In the case of the tension layer 300, it may be made of uncured particles. As described above, when the base layer 100 covers the surface of the packaging container 1, the After contacting the surface, adhesion with the surface of the packaging container 1 is achieved by the action of mutual attraction of the uncured particles.

As shown in FIG. 2, it is preferable that the tension layer 300 is formed of a multilayer, which will be described later.

In the case of the base layer 100, it is preferable to have a sufficient area to cover the entire surface of the outlet of the packaging container 1.

In addition, in the case of the base layer 100, it is preferable that the tension layer 300 is removed in a portion of the lower surface facing the outlet. This is to prevent contamination by exposing and contacting the contents of the packaging container 1 with the uncured particles of the tension layer 300 while the base layer 100 has the outlet closed.

In the case of the re-adhesive label sheet paper through differential cohesiveness for each stack according to the present invention, as shown in FIG. 3, it has a function of lowering the wetting angle according to Equation (1) below.

[Equation 1]

Equation (1): γsf=γsl+γlf*cos(θ)

In γsf=γsl+γlf*cos(θ) in Equation (1), γsl means the interfacial tension between the liquid microparticles and the surface on which the microparticles are seated.

γlf means the surface tension of the microparticles in liquid form, γsf means the surface tension of the surface on which the microparticles are seated and is in adsorption equilibrium with the microparticles, and θ means the wetting angle.

In order to explain the increase of the surface tension on the tension covering layer 200, it may be a liquid fine particle, for example, a color ink component for printing, on the tension covering layer 200.

Printing may be selectively and arbitrarily performed on the tension covering layer 200, and when this operation is performed, it means that the surface tension increases as shown in Equation (1) above.

In the case of the tension covering layer 200, as shown in FIG. 4, a plurality of covering particles 201 constituting the tension covering layer 200 are provided.

In the case of the plurality of covering particles 201, since the tension covering layer 200 is made of a polymer synthetic resin, it is not formed in a granular form as shown in FIG. 4, and the individual units of such a polymer synthetic resin are visually understood and particles It is a drawing introduced to explain the manpower of the liver.

In the case of the plurality of covering particles 201, attraction is generated from each other, and the mutual attraction of the plurality of covering particles 201 serves to increase the surface tension of the lower surface of the base layer 100.

That is, the attractive force between the plurality of covering particles 201 should be formed larger than the attractive force due to the material properties of the base layer 100, that is, the range of the restoring force.

In the case of the re-adhesive label sheet paper through differential cohesion according to the present invention, the tension layer 300 includes a solidification layer 310 and an adhesive layer, as shown in FIGS. 2 to 5. layer, 320).

First, as shown in FIG. 5, in the case of the solidification layer 310, the solidification layer 310 is provided under the rest of the base layer 100 and is provided in the lower surface of the tension covering layer 200, and the tension covering layer 200 It corresponds to a configuration that forms a single layer that is adhered to the lower surface of ).

On the other hand, in the case of the aggressive layer 320, as another layer provided under the solidification layer 310, the upper surface is adhered to the lower surface of the tension covering layer 200, and the lower surface has adhesive strength. By providing a configuration that is selectively adhered to the surface of the packaging container.

In more detail, in the case of the solidification layer 310, curing proceeds in contact with the lower surface of the tension covering layer 200 and the upper surface of the aggressive layer 320, and the adhesive layer is applied to the tension covering layer 200. It corresponds to the configuration of fixing (320).

That is, the solidification layer 310 performs a function of adhesion, not adhesion, through solidification, and fixes the position of the adhesive layer 320 corresponding to the adhesion layer. By preventing the horizontal or vertical separation of the layer 320, interfacial destruction can only occur.

Through solid solidification of the solidification layer 310, the solidification layer 310 prevents cohesive failure and mediates interfacial failure.

The solidification layer 310 mediates the progressive layer 320, and the solidification layer 310 does not directly contact the packaging container 1, so that the substrate is not destroyed.

In the case of the solidification layer 310, a plurality of hardened particles 311 may be included, and the plurality of hardened particles 311 are the lower surface of the tension covering layer 200 and the upper surface of the aggressive layer 320 Curing proceeds in contact with and thus has a function of fixing and attaching the aggressive layer 320 to the tension covering layer 200.

As shown in Figs. 5 and 6, the hardened particles 311 have a very strong spacing d31 between the particles and a mutual attraction f31 between the particles, and this mechanism exerts a very strong force before and after hardening. Thus, the adhesive layer 320 is firmly attached to the tension covering layer 200.

In the case of the aggressive layer 320, as shown in Figs. 5 to 7, the upper side is fixedly attached to the solidification layer 310, and the lower side is attached to the other surface, for example, the surface of the packaging container 1 It allows arbitrary adhesion to be made by the user's choice.

In the case of the aggressive layer 320, it may be made of a set of a plurality of uncured particles 321, and the set of the non-cured particles 321 is a certain part of each other due to the three-dimensional shape of the surface to which the position is contacted. The separation distance d32 may vary.

In more detail, in the case of a plurality of uncured particles 321, the upper surface is fixedly attached to the cured plurality of cured particles 311, and the plurality of non-cured particles 321 generate cohesive force (f32) therebetween. When the lower surface touches the surface of the packaging container 1, the plurality of uncured particles 321 can be adhered to the surface of the packaging container 1 using this cohesive force f32.

Referring to FIG. 7, when the mutual separation distance d32 of the plurality of uncured particles 321 increases, a force for maintaining the original separation distance between the distant particles, that is, mutual attraction is generated, so that the packaging container 1 It grabs the surface of.

On the contrary, when the mutual separation distance d32 becomes close to each other, a force for maintaining the original separation distance between them, that is, mutual repulsion, is generated, and another force capable of holding the surface of the packaging container 1 acts. .

As shown in FIG. 7, there is a mutual attraction f32 between the plurality of uncured particles 321, and this attraction is that the particles present at the bottom have a greater attraction due to the upper part, thereby, In the process of removing the base layer 100 from the surface of the packaging container 1 by the user, clean interface destruction can occur.

As shown in Figs. 8 and 9, the tension layer 300 is not formed only in a predetermined area on the base layer 100 and the tension covering layer 200, for example, the size of an area that can be held by the user in the label paper. Can be avoided.

As shown in FIGS. 8 and 9, the tension layer 300 forms a step d. Among the lower surface of the tension covering layer 200, a predetermined region of the region in which the tension layer 300 is not formed. A blocking layer 400 having a thickness equal to the step d may be selectively formed.

Due to the presence of the blocking layer 400, the tension layer 300 can prevent the transition to the side due to unexpected phenomena such as adhesion and re-adhesion, or horizontal friction during use.

The blocking layer 400 may be composed of thick printed particles, or any other physical material can prevent the transition of the aggressive layer 320 of the tension layer 300 to the side of the uncured particles. I would say that everything is possible.

The adhesion of the tension layer 300 is further enhanced through energy applied through the tension covering layer 200 by applying heat and/or pressure to the base layer 100, the tension covering layer 200 and the tension layer 300 stacked thereon. It can be further improved.
