Description

Technical Field

[0001] This utility model relates to the field of label printing technology, specifically to label paper for printing. Background Technology

[0002] Adhesive ribbon printing labels typically consist of a roll, release paper, and multiple labels. The release paper is wound onto the roll, and the back of each label has an adhesive layer that can be stuck onto the release paper. After the ribbon label printer prints information onto the label, the user can peel the label off the release paper and stick the printed label onto the surface of the object to be labeled.

[0003] In related technologies, after the bonding of the laminating layer and the information paper layer is completed, it is usually necessary to overcome the adhesive force between the first release paper and the laminating layer to separate the first release paper from the laminating layer. The arrangement relationship between the release paper and the laminating layer will affect the integrity of the separation between the first release paper and the laminating layer. Sometimes, the label paper may even separate from the release paper first.

[0004] Therefore, there is an urgent need for printing label paper to solve the problem in the existing technology where the arrangement of the release paper and the coating layer affects the integrity of the separation between the first release paper and the coating layer, and sometimes the label paper even separates from the release paper first. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a label paper for printing, which solves the technical problem in the prior art where the adhesive force required to separate the first release paper from the coating layer is affected by the length of the coating layer or the printed information layer, resulting in inconvenient operation.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0008] At least one printing unit, the printing unit including a first release paper, a label layer and a laminating layer, the first release paper including a first region and a second region, the first region and the second region being arranged along the length direction of a single printing unit, a fold line being provided between the first region and the second region, the label layer being disposed in the first region, the laminating layer being disposed in the second region, the first release paper being folded along the fold line so that the laminating layer covers and adheres to the label layer.

[0009] In some embodiments, the fold line is located at the center line of the first release paper, the first region and the second region are symmetrically distributed horizontally or vertically along the fold line, and the first region and the second region are connected by the fold line.

[0010] In some embodiments, the aspect ratio of a single printing unit ranges from 1.1:1 to 12:1.

[0011] In some embodiments, the side of the label layer opposite to the first release paper is used to add printing information, and the side of the laminating layer opposite to the first release paper is further provided with a first adhesive layer, which is used to bond to the laminating layer and the label layer respectively.

[0012] In some embodiments, the printing unit further includes a second adhesive layer disposed between the label layer and the first release paper. The two sides of the second adhesive layer are respectively bonded to the label layer and the first release paper, and the adhesive strength of the second adhesive layer is such that when the label layer and the first release paper are separated, the first adhesive layer always keeps the film layer and the label layer in an bonded state.

[0013] In some embodiments, the printing unit further includes a third adhesive layer disposed between the laminating layer and the first release paper. The two sides of the third adhesive layer are respectively bonded to the laminating layer and the first release paper. The third adhesive layer is AB double-sided adhesive, and the adhesive strength between the third adhesive layer and the laminating layer is less than the adhesive strength between the third adhesive layer and the first release paper. The adhesive strength of the third adhesive layer satisfies the requirement that when the laminating layer is separated from the first release paper, the first adhesive layer always keeps the laminating layer and the label layer in an adhesive state, and the third adhesive layer remains on the first release paper.

[0014] In some embodiments, the surface of the coating layer is further provided with a second release paper, the second release paper comprising a first portion and a second portion, the first portion and the second portion being disconnected.

[0015] In some embodiments, the break lines of the first portion and the second portion extend along the width direction of a single printing unit.

[0016] In some embodiments, the break lines of the first portion and the second portion extend along the length direction of a single printing unit, and the interval between the first region and the second region is greater than 2 mm.

[0017] In some embodiments, along the length direction of a single printing unit, the size of both the first region and the second region is no greater than 50 mm.

[0018] In some embodiments, when the first region and the second region are folded along the fold line, the side edge of the first region is aligned with the side edge of the second region.

[0019] In some embodiments, the printing unit includes a plurality of printing units, which are spaced apart along the width direction of a single printing unit.

[0020] In some embodiments, the printing unit includes a plurality of printing units, which are spaced apart along the length direction of a single printing unit, and a connecting line is formed between two adjacent printing units, wherein the connection strength between two adjacent printing units is less than or equal to the connection strength between the first region and the second region.

[0021] In some embodiments, the connecting lines are dotted to form a point-to-point connection between two adjacent printing units.

[0022] In some embodiments, the label paper for printing further includes a roller for winding around a plurality of the printing units.

Compared to existing technologies, by arranging the first and second regions along the length of a single printing unit, after the bonding of the laminating layer and the information paper layer is completed, the connection length that needs to be overcome to separate the first and second regions of the first release paper is changed from the original length dimension of the label layer or laminating layer to the width dimension of the label layer or laminating layer. At this time, the connection force to overcome the width dimension of the label layer or laminating layer is less than the connection force to overcome the length dimension of the label layer or laminating layer. This makes it easier for users to peel the first release paper off the laminating layer or label layer. The operation is simple and can solve the problem in existing technologies where the arrangement relationship between the release paper and the laminating layer affects the integrity of the separation between the first release paper and the laminating layer, and sometimes even the label paper separates from the release paper first.

[0048] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0049] To address the technical problem that the arrangement of the release paper and the laminating layer 13 affects the integrity of the separation between the first release paper 11 and the laminating layer 13, and sometimes even causes the label paper to separate from the release paper first, this utility model provides a label paper for printing. After the laminating layer 13 and the information paper layer are bonded, the connection length that needs to be overcome to separate the first release paper 11 from the laminating layer 13 is changed from the original length dimension of the laminating layer 13 to the width dimension of the laminating layer 13. At this time, the connection force to overcome the width dimension of the laminating layer 13 is less than the connection force to overcome the length dimension of the laminating layer 13, which makes it convenient for users to peel the first release paper 11 off the laminating layer 13, and the operation is simple.

[0050] It should be noted that the label paper for printing described in this utility model is used in, but not limited to, the field of label printing technology. For ease of explanation, this utility model only uses the application of the label paper for printing in the field of label printing technology as an example for explanation. The principle of the label paper for printing in other types of equipment is essentially the same as that for the application in the field of label printing technology, and will not be described in detail here.

[0051] Please see Figure 1 , Figure 1 , Figure 2 This is a schematic diagram of the structure of a label paper for printing according to an embodiment of the present invention. The label paper for printing includes at least one printing unit 1. The printing unit 1 includes a first release paper 11, a label layer 12, and a coating layer 13. The first release paper 11 includes a first region 111 and a second region 112. The first region 111 and the second region 112 are arranged along the length direction of a single printing unit 1. A fold line 113 is provided between the first region 111 and the second region 112. The label layer 12 is disposed in the first region 111, and the coating layer 13 is disposed in the second region 112. Folding the first release paper 11 along the fold line 113 allows the coating layer 13 to cover and adhere to the label layer 12.

[0052] In this device, the printing unit 1 includes a first release paper 11, a label layer 12, and a coating layer 13. The label layer 12 and the coating layer 13 are respectively disposed on the first region 111 or the second region 112, and the first region 111 and the second region 112 are distributed on both sides of the fold line 113. Folding the first release paper 11 along the fold line 113 enables the coating layer 13 to be laminated and pasted onto the label layer 12, and the first region 111 and the second region 112 are arranged along the length direction of a single printing unit 1.

[0053] Compared to existing technologies, by arranging the first region 111 and the second region 112 along the length of a single printing unit 1, after the bonding of the laminating layer 13 and the information paper layer is completed, the connection length that the laminating layer 13 needs to overcome to separate the first release paper 11 is changed from the original length dimension of the laminating layer 13 to the width dimension of the laminating layer 13. At this time, the connection force to overcome the width dimension of the laminating layer 13 is less than the connection force to overcome the length dimension of the laminating layer 13. This makes it easier for users to peel the first release paper 11 off the laminating layer 13. The operation is simple and can solve the problem in existing technologies where the arrangement relationship between the release paper and the laminating layer 13 affects the integrity of the separation between the first release paper 11 and the laminating layer 13, and sometimes even the label paper separates from the release paper first.

[0054] In this embodiment, as Figure 2 As shown, the fold line 113 is located at the center line of the first release paper 11. The first region 111 and the second region 112 are distributed symmetrically from left to right or from top to bottom along the fold line 113, and the first region 111 and the second region 112 are connected by the fold line 113.

[0055] The first region 111 and the second region 112 are symmetrically distributed along the fold line 113, which makes it convenient for the user to fold the first release paper 11 and to make it easy to stick the film layer 13 onto the label layer 12.

[0056] In one embodiment, the aspect ratio of a single printing unit 1 is between 1.1:1 and 12:1.

[0057] The aspect ratio of the printing unit 1 is set in the range of 1.1:1 to 12:1, which can effectively achieve the separation of the first release paper 11 and the coating layer 13.

[0058] Understandably, the aspect ratio cannot be less than 1.1, otherwise it is easier for background technology problems to occur. Similarly, the aspect ratio cannot be greater than 12, as the lamination effect will be worse if it is greater than 12, and even the lamination will be prone to misalignment.

[0059] In one embodiment, such as Figure 2 As shown, the side of the label layer 12 facing away from the first release paper 11 is used to add printing information 14, and the side of the film layer 13 facing away from the first release paper 11 is also provided with a first adhesive layer 15, which is used to bond to the film layer 13 and the label layer 12 respectively.

[0060] The first adhesive layer 15 is attached to the film layer 13 and can be bonded to the label layer 12. It is used to cover and protect the side of the label layer 12 away from the first release paper 11 by adding printed information 14.

[0061] In one embodiment, such as Figure 2As shown, the printing unit 1 also includes a second adhesive layer 16, which is disposed between the label layer 12 and the first release paper 11. Both sides of the second adhesive layer 16 are bonded to the label layer 12 and the first release paper 11, respectively. The adhesive strength of the second adhesive layer 16 is such that when the label layer 12 and the first release paper 11 are separated, the first adhesive layer 15 always keeps the film layer 13 and the label layer 12 in an bonded state.

[0062] The second adhesive layer 16 is used to attach the label layer 12 to the product. At the same time, by setting the adhesive strength between the second adhesive layer 16 and the first release paper 11 to be less than the adhesive strength between the first adhesive layer 15 and the film layer 13 and the label layer 12, it is possible to avoid the accidental separation of the first adhesive layer 15 from the film layer 13 and the label layer 12 when separating the first area 111 of the first release paper 11 from the label layer 12.

[0063] Furthermore, both the first adhesive layer 15 and the second adhesive layer 16 are pressure-sensitive adhesives. The pressure-sensitive adhesive of the first adhesive layer 15 is mainly used to connect the lamination layer 13 to the printed information layer 14 and the label layer 12 after the first release paper 11 is flipped and folded, so that the lamination layer 13 can protect the printed information layer 14 and the label layer 12. The pressure-sensitive adhesive of the second adhesive layer 16 is mainly used to adhere to the bonding area after the first release paper 11 is peeled off, such as the product surface or wall. The pressure-sensitive adhesive used here is a conventional setting known to those skilled in the art and will not be described in detail.

[0064] In one embodiment, such as Figure 2 As shown, the printing unit 1 also includes a third adhesive layer 17, which is disposed between the film layer 13 and the first release paper 11. The two sides of the third adhesive layer 17 are respectively bonded to the film layer 13 and the first release paper 11. The third adhesive layer 17 is AB double-sided adhesive, and the bonding strength between the third adhesive layer 17 and the film layer 13 is less than the bonding strength between the third adhesive layer 17 and the first release paper 11. The bonding strength of the third adhesive layer 17 satisfies the requirement that when the film layer 13 is separated from the first release paper 11, the first adhesive layer 15 always keeps the film layer 13 and the label layer 12 in an adhesive state, and the third adhesive layer 17 remains on the first release paper 11.

[0065] The third adhesive layer 17 is used to bond the second region 112 to the coating layer 13.

[0066] Furthermore, the adhesive strength between the third adhesive layer 17 and the coating layer 13 is less than the adhesive strength between the third adhesive layer 17 and the first release paper 11, and the adhesive strength between the third adhesive layer 17 and the first release paper 11 is less than the adhesive strength between the first adhesive layer 15 and the coating layer 13 and the label layer 12. This facilitates the separation of the first release paper 11 and the coating layer 13, and prevents the third adhesive layer 17 from adhering to the coating layer 13. At the same time, it can prevent the accidental separation between the first adhesive layer 15, the coating layer 13, and the label layer 12 due to the separation of the first release paper 11 and the coating layer 13.

[0067] Furthermore, the use of AB double-sided tape is a standard setup known to those skilled in the art, and will not be elaborated upon further.

[0068] In this embodiment, as Figure 2 As shown, the surface of the coating layer 13 is also provided with a second release paper 18, which includes a first part and a second part, and the first part and the second part are disconnected.

[0069] The second release paper 18 covers the surface of the first adhesive layer 15 to protect the first adhesive layer 15 from excessive dust that could weaken its adhesiveness before use. Figure 1 As shown, the second release paper 18 is composed of a first part and a second part and is separated from each other. It can also be understood that the first part and the second part are separated by a solid knife line. The first part and the second part together cover all parts of the first adhesive layer 15, which makes it easy to separate the second release paper 18 from the first adhesive layer 15.

[0070] Furthermore, such as Figure 4 As shown, one end of the second release paper 18 may not cover the first adhesive layer 15, while the other end of the second release paper 18 may be completely attached to the first adhesive layer 15. That is, in this embodiment, the area of ​​the second release paper 18 is slightly smaller than the area of ​​the first adhesive layer 15, so that the second release paper 18 can be quickly torn off to detach from the first adhesive layer 15.

[0071] In one embodiment, such as Figure 1 As shown, the break lines of the first and second parts extend along the width direction of a single printing unit 1.

[0072] It is understandable that the break line of the first part 181 and the second part 182 is set parallel to the fold line 113. When the second release paper 18 is torn open through the break between the first part and the second part, the impact on the label layer 12 of the first area 111 is small. The label layer will not be bent, and it is not easy for the label paper to detach from the first release paper 11 when the second release paper 18 is torn open. As a result, during the secondary separation, the label layer 12 and the first release paper 11 separate preferentially than the film layer 13 and the first release paper 11.

[0073] In one embodiment, such as Figure 5 As shown, the break lines of the first and second parts extend along the length direction of a single printing unit 1, and the interval between the first region 111 and the second region 112 is greater than 2 mm.

[0074] It is understandable that the break lines of the first part and the second part extend along the length direction of a single printing unit 1, that is, the break lines of the first part 181 and the second part 182 are set perpendicular to the fold line 113. Even if the label layer 12 of the first area 111 is bent when the second release paper 18 is torn at the break between the first part and the second part, the impact can be reduced by setting the interval between the first area 111 and the second area 112 to be greater than 2mm. If the interval is too short, the impact on the label layer 12 of the first area 111 will be greater when the second release paper 18 is torn at the break between the first part and the second part.

[0075] In one embodiment, the dimensions of the first region 111 and the second region 112 are both no greater than 50 mm along the length of a single printing unit 1.

[0076] It is understandable that if the interval between the first region 111 and the second region 112 is set too long, misalignment may easily occur during the folding process of the first region 111 and the second region 112. Therefore, the interval between the first region 111 and the second region 112 should be within the range of 2mm to 50mm.

[0077] In this embodiment, as Figure 2 As shown, when the first region 111 and the second region 112 are folded along the fold line 113, the side of the first region 111 is aligned with the side of the second region 112.

[0078] It is understandable that aligning the side of the first region 111 with the side of the second region 112 can effectively ensure that the coating layer 13 can cover and protect the entire label layer 12.

[0079] In one embodiment, such as Figure 1 As shown, the printing unit 1 includes multiple units, which are arranged at intervals along the width direction of a single printing unit 1.

[0080] The fold line 113 is set in the same direction as the width of a single printing unit 1, and the first region 111 and the second region 112 are symmetrically distributed along the fold line 113 as the axis of symmetry, and are arranged sequentially in a direction perpendicular to the winding. In this way, when the printed printing unit 1 is torn off, the risk of the first region 111 and the second region 112 separating can be minimized.

[0081] In another embodiment, such as Figure 3 As shown, the printing unit 1 includes multiple units, which are spaced apart along the length of a single printing unit 1, and a connecting line 2 is formed between two adjacent printing units 1. The connection strength between two adjacent printing units 1 is less than or equal to the connection strength between the first region 111 and the second region 112.

[0082] It is understood that the setting direction of the fold line 113 is consistent with the width direction of the single printing unit 1, and the first region 111 and the second region 112 are symmetrically distributed vertically along the fold line 113 as the axis of symmetry, and are set sequentially along the winding direction.

[0083] Furthermore, a connecting line 2 is formed between two adjacent printing units 1. Here, both the fold line 113 and the connecting line 2 are easy-tear structures known to those skilled in the art, which facilitates tearing a single printing unit 1 off the label after printing is completed. Further details will not be elaborated here.

[0084] Furthermore, the connection strength at the connecting line 2 is greater than that at the fold line 113, which can prevent the accidental separation of the first region 111 and the second region 112 of the first release paper 11 when the individual printing unit 1 is separated.

[0085] In another embodiment, such as Figure 6 , Figure 7 As shown, the connecting line 2 is dotted, which is used to form a point-to-point connection between two adjacent printing units 1.

[0086] By connecting two adjacent printing units 1 through a point-to-point connection method, users can easily separate the two adjacent printing units 1 after printing is completed.

[0087] Specifically, as shown in the figure, two adjacent printing units 1 in this device are connected by connection points that are arranged in an "inverted triangle" or "horizontally set bracket shape". This allows the two adjacent printing units 1 to be connected only point-to-point and can be easily broken, making it convenient for users to operate.

[0088] In this embodiment, as Figure 1 , Figure 3 As shown, the device also includes a roller 3, which is used to wind multiple printing units 1.

[0089] The printing paper is wound and rolled onto roller 3, making it easy for the printing paper to unfold and be used in the printer.

[0090] Furthermore, the roller 3 is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0091] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail below:

[0092] The printing unit 1 includes a first release paper 11, a label layer 12, and a laminating layer 13. The label layer 12 and the laminating layer 13 are respectively disposed on a first region 111 or a second region 112, and the first region 111 and the second region 112 are distributed on both sides of the fold line 113. Folding the first release paper 11 along the fold line 113 enables the laminating layer 13 to be laminated and pasted onto the label layer 12, and the first region 111 and the second region 112 are arranged along the length direction of a single printing unit 1. Compared to existing technologies, by arranging the first region 111 and the second region 112 along the length of a single printing unit 1, after the bonding of the film layer 13 and the information paper layer is completed, the connection length that the film layer 13 needs to overcome to separate the first release paper 11 is changed from the original length dimension of the film layer 13 to the width dimension of the film layer 13. At this time, the connection force to overcome the width dimension of the film layer 13 is less than the connection force to overcome the length dimension of the film layer 13, which makes it easier for users to peel the first release paper 11 off the film layer 13, and the operation is simple.

[0093] The specific workflow of this utility model is as follows: First, two adjacent printing units 1 can be easily separated by the connecting line 2. Then, the second release paper 18 is peeled off from the film layer 13, and the first area 111 and the second area 112 of the first release paper 11 are folded along the fold line 113, so that the film layer 13 connects the printed information and the label layer 12 through the first adhesive layer 15. Then, the second area 112 of the first release paper 11 is peeled off from the film layer 13, and the first area 111 and the second area 112 are separated along the fold line 113. Finally, the first area 111 of the first release paper 11 is peeled off from the printing layer. The user holds the film layer 13, the printed information 14 and the label layer 12 that form a whole and sticks them on the product or object.

[0094] Furthermore, the direction of the fold line 113 is parallel to the width direction of the label layer 12 and the laminating layer 13, so that when the second region 112 of the first release paper 11 is peeled off from the laminating layer 13, the connection length that needs to be overcome to separate the second region 112 of the first release paper 11 is changed from the original length dimension of the laminating layer 13 to the width dimension of the laminating layer 13. At this time, the connection force overcoming the width dimension of the laminating layer 13 is less than the connection force overcoming the length dimension of the laminating layer 13, which makes it easier for the user to operate.

[0095] This device, through the above structure, can solve the problem in the prior art where the arrangement relationship between the release paper and the coating layer 13 affects the integrity of the separation between the first release paper 11 and the coating layer 13, and sometimes even the label paper separates from the release paper first.

[0096] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
