Description

Technical Field

[0001] The present invention relates to the technical field of self - adhesive label production, and particularly relates to a preparation method for self - adhesive labels. Background Art

[0002] Self - adhesive labels are a composite material, composed of a face material (the carrier for printing graphics and texts), an adhesive (the back coating), and a backing paper (silicone - coated protective paper). When in use, only the backing paper needs to be peeled off, and it can be directly pasted on the target surface. For current self - adhesive labels, they are formed by compounding with conventional compounding equipment. Their backing paper is thin and made of silicone - coated paper. After the face material is peeled off and used, the backing paper cannot be reused. Moreover, such labels are in a roll - paper structure. In the scenario of manual peeling and pasting, the face material is prone to accidental contact during storage, resulting in partial peeling or damage. In specific use scenarios where the cost of the face material is high, the resulting losses are too large and need to be avoided. Summary of the Invention

[0003] The present invention is to avoid the deficiencies of the prior art and provides a preparation method for self - adhesive labels.

[0004] The present invention solves the technical problems by adopting the following technical solutions: A preparation method for self - adhesive labels, characterized in that the self - adhesive label includes a base layer. The base layer has two opposite flat surfaces, and a plurality of grooves are evenly distributed on the flat surfaces. A label layer is bonded in the grooves. A protective layer is arranged outside the flat surfaces, and the protective layer covers the label layer inside. The preparation method for the self - adhesive label includes the following steps:

[0005] S10: Prepare the base layer. After surface - treating the silicone rubber sheet, cut it into multiple base layers with a certain thickness, length, and width, and process a plurality of grooves on the two flat surfaces of the base layer;

[0006] S20: Prepare the label body. Cut the label substrate into a label body adapted to the size of the base layer, mark the label body to form the positions of a plurality of label layers, and then apply glue to the label body;

[0007] S30: Compounding. Cover a label body on one flat surface of the base layer, with the position of the label layer corresponding to the position of the groove. Press the label body onto the base layer by pressing with a template. Flip the base layer, cover another label body on the other flat surface, and press it by pressing with a template;

[0008] S40: Drying. Send the product after step S30 into an oven for baking;

[0009] S50: Cutting. Cut the product after step S40, and cut on the label body to remove the blank positions to form the label layer;

[0010] S60: Prepare a protective layer. Cut the film into a protective layer adapted to the size of the base layer, apply glue to the edge position of the protective layer, cover it on the flat surface treated in S50, and cover the label layer inside to form a finished self-adhesive label.

[0011] In several embodiments, in step S20, when applying glue, the entire surface of the label body is coated with glue.

[0012] In several embodiments, in step S20, when applying glue, local gluing is performed at the position corresponding to the label layer in the label body.

[0013] In several embodiments, in step S40, the baking temperature is 180 - 220 °C and the baking time is 1 - 3 minutes.

[0014] In several embodiments, at least one corner of the protective layer has an outward protrusion to form a peeling end.

[0015] The beneficial effects of the present invention are as follows:

[0016] The present invention uses a silica gel plate to replace the base paper structure, which can be recycled and reused. At the same time, it forms a plate structure with a certain thickness, which is convenient for stacking and storage. At the same time, the combination of the protective layer avoids accidental contact and damage.

[0017] The present invention adopts a double-sided structure, and label layers are arranged on both sides of the base layer to improve the utilization rate.

[0018] The present invention avoids coating silicone oil through the silica gel plate, which is more environmentally friendly.

[0019] The present invention further improves the protection effect on the label layer through the groove structure. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] As Figures 1 - 3 shown, the self-adhesive label provided in this embodiment includes a base layer 10. The base layer 10 has two relatively arranged flat surfaces. A plurality of grooves 11 are evenly distributed on the flat surfaces. A label layer 20 is adhered in the grooves 11. The depth of the grooves 11 is slightly greater than the thickness of the label layer 20. A protective layer 30 is provided outside the flat surfaces. The protective layer 30 covers the label layer 20 therein. Here, the protective layer 30 is a whole and complete structure that covers all the label layers 20 within this surface. Moreover, at least one corner of the protective layer 30 has an outward protrusion to form a peeling end 31. Pinching the peeling end 31 facilitates peeling off the protective layer 30.

[0029] The preparation method of the self-adhesive label in this embodiment includes the following steps:

[0030] First, the base layer 10 is prepared. After the silicone sheet is surface-treated, it is cut into multiple base layers 10 with a certain thickness, length, and width. A plurality of grooves 11 are processed on the two flat surfaces of the base layer 10. The grooves can be formed by laser etching.

[0031] Second, the label body is prepared. The label substrate is cut into a label body adapted to the size of the base layer 10. The label body is marked to form the positions of a plurality of label layers 20. Subsequently, the label body is coated with glue. When coating the glue, the entire surface of the label body is coated with glue.

[0032] Second, the lamination is carried out. A label body is covered on one flat surface of the base layer 10. The position of the label layer 20 corresponds to the position of the groove 11. The label body is pressed onto the base layer 10 by pressing down a template. The base layer 10 is flipped, and another label body is covered on the other flat surface and pressed by pressing down the template. The template has a plurality of protrusions, and the positions and shapes of the protrusions are the same as those of the grooves 11.

[0033] Next is drying. The product after step S30 is sent into an oven for baking. The baking temperature is 180 - 220 °C, and the baking time is 1 - 3 minutes.

[0034] Next is cutting. The product after step S40 is cut. Cutting is performed on the label body to remove the blank positions, forming the label layer 20.

[0035] Finally, the protective layer 30 is prepared. The film is cut into the protective layer 30 adapted to the size of the base layer 10. Glue is applied to the edge positions of the protective layer 30, and it is covered on the flat surface after being treated by S50, and the label layer 20 is covered inside, forming the finished self - adhesive label.

[0036] Embodiment 2

[0037] As Figure 4 shown, in this embodiment, the difference from Embodiment 1 is that the protective layer 30 is of a split structure, and each label layer 20 is correspondingly covered with a protective layer 30. That is, during the process of preparing the protective layer 30, glue needs to be applied to the edge positions corresponding to the label layer 20 in the protective layer, that is, the dot - glue method is used to form a mouth - shaped trajectory. Finally, cutting is performed again to remove the film at the vacant positions, forming a plurality of protective layer 30 structures.

[0038] Embodiment 3

[0039] In this embodiment, the difference from the above embodiments is that in the step of preparing the label body, the label substrate is cut into a label body adapted to the size of the base layer 10, marking is performed on the label body to form the positions of a plurality of label layers 20, and then glue is applied to the label body. When applying glue, local glue application is performed on the positions corresponding to the label layer 20.

[0040] All the described methods herein can be carried out in any suitable order. Any and all examples used, or the exemplary language provided herein (such as "for example") are only for better explaining the present invention and do not limit the scope of the present invention, unless otherwise claimed. The language in the detailed description should not be construed as indicating any essential elements for practicing the present invention that are not claimed.
