Description

Technical Field

[0001] The utility model relates to the field of label paper, in particular to an anti-bubble type non-adhesive label paper. Background Art

[0002] Self-adhesive labels, also known as self-adhesive labels or sticky notes, are a composite material made of paper, film or other specialty materials, with an adhesive on the back and a silicone-coated protective paper as the backing. After printing, die-cutting and other processing, the self-adhesive label becomes a finished sticker. When used, simply peel it off from the backing paper and lightly press it to stick to the surface of various substrates.

[0003] When using existing anti-bubble non-stick label paper, the effect of the flatness of the surface of the object to which the label is attached on the adhesion effect is not taken into consideration. When there are raised areas on the surface to be attached, the label will be slightly deformed. After a long time, a cavity or warped edge will be formed at the raised area, which will greatly reduce the adhesion effect on the surface of the object, and then cause the label to fall off easily. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technology, the existing anti-bubble non-stick label paper does not take into account the impact of the flatness of the surface of the object to which the label is attached on the sticking effect when it is used. When there are protrusions on the surface to be attached, the label will be slightly deformed. After a long time, a cavity will be formed at the protrusion, which will cause the label to fall off easily. The utility model proposes an anti-bubble non-stick label paper.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an anti-bubble non-stick label paper, including a label shaping layer, the lower surface of the label shaping layer is adhered to a shrinkage layer, the lower surface of the shrinkage layer is adhered to a support layer, the lower surface of the support layer is adhered to an adhesive layer, the lower surface of the adhesive layer is adhered to a colloid layer, the upper surface of the label shaping layer is adhered to a paper layer, and the upper surface of the paper layer is adhered to a hydrophobic layer.

[0006] Preferably, the support layer is made of glass fiber, and the middle part is a mesh structure composed of glass fiber.

[0007] Preferably, the label shaping layer is made of medium carbon steel sheet, and the hydrophobic layer is made of polyethylene film.

[0008] Preferably, the adhesive layer is made of hot melt adhesive, and the shrinkage layer is made of sponge rubber.

[0009] Preferably, a release paper is attached to the lower surface of the colloid layer, and the release paper is made of polyester film.

[0010] Preferably, an easy-tear edge is fixedly connected to one side of the release paper, and the easy-tear edge is made of fragile paper.

[0011] Preferably, air guide holes are provided on the surface of the adhesive layer, and a fixing block is fixedly connected to one side of the label shaping layer.

[0012] The utility model is beneficial in that:

[0013] The utility model provides air guide holes, and the generated bubbles enter the supporting layer through the air guide holes. Since the supporting layer is a mesh structure made of glass fiber, it has good air permeability and shrinkage, and can discharge excess air from all sides. Moreover, when encountering an uneven surface, the mesh structure made of glass fiber can better shrink according to the degree of unevenness to reduce the elastic force generated by deformation. Then, by providing a shrinkage layer, space is reserved for the convex surface, which can greatly reduce the force for the label to return to its original shape, thereby preventing bubbles and cavities from falling off.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The following is combined with Figure 1-4 To further explain this application,

[0023] The present application embodiment discloses an anti-bubble type non-adhesive label paper. Figure 1 and Figure 2 , including a label shaping layer 3, the lower surface of the label shaping layer 3 is adhered to a shrinkage layer 4, the lower surface of the shrinkage layer 4 is adhered to a support layer 5, the lower surface of the support layer 5 is adhered to an adhesive layer 6, the lower surface of the adhesive layer 6 is adhered to a glue layer 7, the upper surface of the label shaping layer 3 is adhered to a paper layer 2, and the upper surface of the paper layer 2 is adhered to a hydrophobic layer 1.

[0024] Reference Figure 2 and Figure 3 The supporting layer 5 is made of glass fiber, and the middle part is a mesh structure composed of glass fiber. The glass fiber material has the characteristics of high elasticity and high tensile strength. By setting the glass fiber mesh, it can be deformed according to the direction of force, so that the label can reach the protruding part of the package surface. At the same time, the mesh structure is conducive to the discharge of gas.

[0025] Reference Figure 1 and Figure 2 The label shaping layer 3 is made of medium carbon steel sheet, and the hydrophobic layer 1 is made of polyethylene film. The label shaping layer 3 can provide rigid support for the entire label to prevent the label from deforming. The polyethylene film material of the hydrophobic layer 1 has waterproof and moisture-proof properties and can provide protection for the paper layer 2 attached to the lower surface.

[0026] Reference Figure 2 and Figure 4 The adhesive layer 7 is made of hot melt adhesive, and the shrinking layer 4 is made of sponge rubber. By setting the shrinking layer 4, the shrinking layer 4 will shrink when subjected to pressure, which can provide space for the protruding parts of the surface. By setting the adhesive layer 7, the surface of the object can be adhered so that the label can be fixed on the surface of the object;

[0027] Reference Figure 1 and Figure 5 The lower surface of the adhesive layer 7 is adhered with a release paper 8, which is made of polyester film. The release paper 8 can protect the hot melt adhesive of the adhesive layer 7 and prevent it from being exposed to the air and absorbing too much dust, which may reduce the adhesion of the label.

[0028] Reference Figure 1 and Figure 5 , one side of the release paper 8 is fixedly connected with an easy-tear edge 11, and the easy-tear edge 11 is made of fragile paper. By setting the easy-tear edge 11, when the label is removed, the label can be torn along the position of the easy-tear edge 11 to avoid damage to the label body;

[0029] Reference Figure 2 and Figure 4 , the surface of the adhesive layer 6 is provided with air guide holes 9, and one side of the label shaping layer 3 is fixedly connected with a fixing block 10. By providing the air guide holes 9 provided in the adhesive layer 6, the surface of the label can be pressed during use, and excess air will enter the supporting layer 5 along the air guide holes 9, and finally be discharged to the outside of the label through the supporting layer 5. By providing the fixing block 10, it is convenient to remove the label by buckling the fixing block 10.

[0030] Working principle: When in use, remove the release paper 8 by pinching the fixed block 10, align the glue layer 7 with the position to be attached, press the label paper, and the bubbles formed by the adhesive layer 6 and the surface of the attached object will enter the support layer 5 through the air guide holes 9 on the surface of the adhesive layer 6. The glass fiber mesh structure of the support layer 5 has high air permeability and can discharge excess air to the surroundings. When there is a protrusion on the surface of the attached object, the glass fiber mesh structure of the support layer 5 will shrink according to the shape of the protrusion, and the soft sponge rubber material of the shrinkage layer 4 will wrap the protrusion inside the label, which greatly reduces the reaction force on the label. When the label is pressed, the whole does not deform, thereby avoiding the bubbles and cavities that are caused by the label returning to its original shape.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
