[0053] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0054] In order to solve the technical problem that fingers can easily come into contact with the glue, thereby affecting the viscosity of the glue and further affecting the bonding effect between the coating area and the printing area, thereby reducing the effectiveness of the coating area in protecting the printing area, the utility model provides printing paper and a thermal transfer label, which can form a spacing area 114 for the user to hold between the edge of the first adhesive layer 15 and the edge of the first release paper 11, thereby preventing the hand from directly contacting the coating layer 13 or the glue layer on the label layer 12, and preventing dust or hands from affecting the viscosity of the hot melt glue layer.

[0055] It should be noted that the printing paper and thermal transfer labels described in the present invention are used in but not limited to the field of label printing technology. For the sake of convenience, in the present invention, only the application of printing paper and thermal transfer labels in the field of label printing technology is used as an example for explanation. The principles of applying printing paper and thermal transfer labels to other types of equipment are essentially the same as those applied to the field of label printing technology, and will not be elaborated here.

[0056] See also Figures 1 to 9 , Figure 1 、 Figure 2This is a structural schematic diagram of printing paper and a thermal transfer label in an embodiment of the present invention. A printing paper includes at least one printing unit 1, and 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 area 111 and a second area 112, and a fold line 113 is formed between the first area 111 and the second area 112. The label layer 12 is stacked on the first release paper 11 layer and is arranged in the first area 111. The coating layer 13 is stacked on the first release paper 11 and is arranged in the second area 112. A first adhesive layer 15 is further provided on the side of the coating layer 13 facing away from the first release paper 11. The first adhesive layer 15 is used to bond with the label layer 12 and the coating layer 13 respectively. The edge of the first adhesive layer 15 is spaced apart from the edge of the first release paper 11. The coating layer 13 can be adhered to the label layer 12 through the first adhesive layer 15 when the first release paper 11 is folded along the fold line 113.

[0057] In this device, the printing paper includes at least one printing unit 1, which includes a first release paper 11, a label layer 12 and a coating layer 13. The first release paper 11 is provided with a first area 111 and a second area 112, and a fold line 113 is formed between the first area 111 and the second area 112. The label layer 12 and the coating layer 13 are respectively arranged on the first area 111 and the second area 112. The coating layer 13 is further provided with a first adhesive layer 15 on the side facing away from the first release paper 11 for bonding to the label layer 12 and the coating layer 13 respectively. The edge of the first adhesive layer 15 is spaced apart from the edge of the first release paper 11. The coating layer 13 can be adhered to the label layer 12 through the first adhesive layer 15 when the first release paper 11 is folded along the fold line 113.

[0058] Compared with the prior art, a first adhesive layer 15 is provided on the coating layer 13 so that the coating layer 13 can be adhered to the label layer 12 for coating and protecting the label layer 12. At the same time, a spacing area 114 for the user to hold is formed between the edge of the first adhesive layer 15 and the edge of the first release paper 11, so as to avoid direct contact of the hand with the coating layer 13 or the glue layer on the label layer 12, and avoid the influence of dust or hands on the viscosity of the hot melt glue layer. This can solve the technical problem in the prior art that the fingers can easily come into contact with the glue, thereby affecting the viscosity of the glue and further affecting the bonding effect between the coating area and the printing area, thereby resulting in a decrease in the effect of the coating area in protecting the printing area.

[0059] Furthermore, the side of the label layer 12 facing away from the first release paper 11 is used for adding printed information 14 , and the covering layer 13 and the first adhesive layer 15 can be bonded to the label layer 12 to protect the printed information 14 .

[0060] In this embodiment, Figure 1 As shown, the edge of at least one side of the label layer 12 is spaced apart from the edge of the first release paper 11 .

[0061] A spacing area 114 is formed on at least one side of the label layer 12. Not only the coating layer 13 but also the label layer 12 is provided with a spacing area 114 to facilitate the user to hold it by hand. It can be understood that if the label layer 12 does not have a position for holding, the direct contact of the hand with the label layer 12 will also affect the bonding effect between the label layer 12 and the coating layer 13.

[0062] Specifically, four sides of the label layer 12 are provided with spacing areas 114 to facilitate user operation.

[0063] In this embodiment, in the arrangement direction of the label layer 12 and the coating layer 13 , the distance between the edge of the first adhesive layer 15 and the edge of the first release paper 11 is greater than the size between the edge of the label layer 12 and the edge of the first release paper 11 .

[0064] Compared with the label layer 12 side, fingers are more likely to cause contamination and influence on the first adhesive layer 15 side. Therefore, the distance between the edge of the first adhesive layer 15 and the edge of the first release paper 11 is greater than the size between the edge of the label layer 12 and the edge of the first release paper 11, which can reduce the influence of fingers on the bonding and protection effects.

[0065] In one embodiment, after the first release paper 11 is folded along the folding line 113 , the edge of the laminating layer 13 does not exceed the edge of the label layer 12 .

[0066] After the label layer 12 is attached to an item and used for a long time, the film layer 13 can easily fall off due to the portion of the film layer 13 that extends beyond the label layer 12. The larger the film layer 13, the larger the corresponding adhesive layer. For a given label size, a smaller blank area makes it less convenient for the user to hold and more susceptible to contamination.

[0067] Furthermore, when the edge of the coating layer 13 exceeds the edge of the label layer 12 after being folded in half, the coating layer 13 may be easily lifted, thereby affecting the effect of the label paper being attached to the product.

[0068] In one embodiment, the distance between the label layer 12 and the covering layer 13 in the arrangement direction thereof is greater than three times the sum of the thicknesses of the label layer 12 and the covering layer 13 , and is less than 10 mm.

[0069] The spacing between the label layer 12 and the covering layer 13 must be greater than the sum of the thicknesses of the label layer 12 , the first adhesive layer 15 , and the covering layer 13 to ensure that the two can be folded in half and accommodate both.

[0070] As a preferred embodiment, the spacing between the label layer 12 and the coating layer 13 in their arrangement direction is greater than three times the sum of the thicknesses of the label layer 12 and the coating layer 13, and is less than 10 mm. It can be within a more reasonable range, which is not only convenient for users to hold, but also does not cause excessive spacing areas 114 and waste paper. If the spacing between the label layer 12 and the coating layer 13 in their arrangement direction is too large, such as greater than 10 mm, then when the label layer 12 and the coating layer 13 are folded in half, they are prone to misalignment, making it impossible for the coating layer 13 to cover the label layer 12 more accurately.

[0071] Furthermore, the width of the spacing area 114 is 1 mm, 1.5 mm, 2 mm, 3 mm, 5 mm, 8 mm, and 10 mm, wherein the width of the spacing area 114 is 1.5 mm, which is a preferred width.

[0072] In this embodiment, Figure 1 As shown, a second release paper 18 is further provided on the surface of the coating layer 13 . The second release paper 18 is connected to the coating layer 13 via the first adhesive layer 15 and is used to protect the first adhesive layer 15 .

[0073] The second release paper 18 is used to protect the first adhesive layer 15 to prevent the first adhesive layer 15 from being exposed to excessive dust and thus weakening its adhesiveness before use.

[0074] In one embodiment, Figure 1 As shown, the second release paper 18 includes a first portion 181 and a second portion 182 . The first portion 181 and the second portion 182 are separated and can together cover all parts of the first adhesive layer 15 .

[0075] The disconnected first portion 181 and the second portion 182 can facilitate the user to separate the first portion 181 or the second portion 182 from the first adhesive layer 15 , thereby facilitating operation.

[0076] Furthermore, if Figure 6 As shown, one end of the second release paper 18 may not cover the first adhesive layer 15, and 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 separate from the first adhesive layer 15.

[0077] In one embodiment, the covering layer 13 is a transparent PET film.

[0078] The transparent PET film does not affect the exposure of the label layer 12. The PET film also has good heat resistance, cold resistance, corrosion resistance and oil resistance, and can provide stable protection for the label layer 12 so that the label layer 12 can be used for a long time. The PET film here is a conventional setting known to those skilled in the art and will not be described in detail.

[0079] In one embodiment, Figure 1 As shown, the second release paper 18 is in a long strip shape, and the first portion 181 and the second portion 182 are separated along the length direction of the second release paper 18 .

[0080] like Figure 1 As shown, the second release paper 18 is in the shape of a long strip, and the first part 181 and the second part 182 are separated along the length direction of the second release paper 18, so that the first part 181 or the second part 182 can be easily torn off from the first adhesive layer 15, that is, when tearing off the first part 181 or the second part 182, it is only necessary to tear off the width direction of the second release paper 18, which is convenient for operation.

[0081] Furthermore, if Figure 7 As shown, the first portion 181 and the second portion 182 may also be separated along the width direction of the second release paper 18 .

[0082] In one embodiment, the ratio of the area occupied by the first portion 181 to the area occupied by the second portion 182 is 1:2 to 1:10.

[0083] like Figure 1 As shown, by setting the first part 181 and the second part 182 with an area ratio of 1:2 to 1:10, the contamination of the first adhesive layer 15 can be reduced and the bonding effect can be improved. It can be understood that if the first part 181 is torn off first and then the second part 182 is torn off, the second part 182 with a larger area is exposed to the air for a shorter time, so the probability of being contaminated will also be smaller, thereby further improving the bonding effect.

[0084] In one embodiment, the distance between the edge of the first adhesive layer 15 and the edge of the first release paper 11 ranges from 1 mm to 8 mm.

[0085] Optimally, the distance between the edge of the first adhesive layer 15 and the edge of the first release paper 11 is 1 mm, 1.5 mm, 5 mm, or 8 mm, with 1.5 mm being the preferred value.

[0086] In this embodiment, Figure 2 As shown, the folding line 113 is set at the center line of the first release paper 11, and the first area 111 and the second area 112 are symmetrically distributed left and right or up and down along the folding line 113 as the symmetry axis.

[0087] The first area 111 and the second area 112 are symmetrically distributed along the folding line 113 , so that the covering layer 13 can better cover the label layer 12 and facilitate separation of the first area 111 and the second area 112 .

[0088] like Figure 3 As shown, the first area 111 and the second area 112 are symmetrically distributed along the fold line 113, so that the label layer 12 and the coating layer 13 can be symmetrically distributed along the length direction of the printing paper, as shown in FIG. Figure 4 As shown, the first area 111 and the second area 112 are symmetrically distributed along the fold line 113, so that the label layer 12 and the coating layer 13 are symmetrically distributed along the length direction perpendicular to the printing paper.

[0089] Furthermore, if Figure 5 As shown, the length direction of the label layer 12 and the coating layer 13 can also be set to be consistent with the length direction of the printing unit 1 winding, or as shown in FIG. Figure 4 As shown, the width direction of the label layer 12 and the covering layer 13 is consistent with the length direction of the printing unit 1 winding.

[0090] In one embodiment, Figure 2 As shown, the printing unit 1 also includes a second adhesive layer 16, which is arranged between the label layer 12 and the first release paper 11. The two sides of the second adhesive layer 16 are respectively bonded to the label layer 12 and the first release paper 11, and the bonding strength between the second adhesive layer 16 and the first release paper 11 meets the requirement that when the label layer 12 and the first release paper 11 are separated, the first adhesive layer 15 always keeps the coating layer 13 and the label layer 12 in a bonded state.

[0091] The second adhesive layer 16 is used to achieve adhesion between the first release paper 11 and the label layer 12 .

[0092] Furthermore, the bonding strength between the second adhesive layer 16 and the first release paper 11 is less than the bonding strength between the first adhesive layer 15 and the coating layer 13 and the label layer 12, so that when the first release paper 11 is separated from the label layer 12, the second adhesive layer 16 is adhered to the label layer 12, while preventing the coating layer 13 from being separated from the label layer 12.

[0093] Furthermore, the first adhesive layer 15 and the second adhesive layer 16 in the present device are both pressure-sensitive adhesives, which are conventionally used by those skilled in the art and will not be described in detail.

[0094] In one embodiment, Figure 2As shown, the printing unit 1 also includes a third adhesive layer 17, which is arranged between the coating layer 13 and the first release paper 11. The third adhesive layer 17 is an AB double-sided tape. Both sides of the third adhesive layer 17 are respectively bonded to the coating layer 13 and the first release paper 11, and the bonding strength of the third adhesive layer 17 meets the requirement that when the coating layer 13 is separated from the first release paper 11, the first adhesive layer 15 always keeps the coating layer 13 and the label layer 12 in a bonded state, and the third adhesive layer 17 remains on the first release paper.

[0095] The third adhesive layer 17 is used to achieve adhesion between the first region 111 or the second region 112 of the first release paper 11 and the covering layer 13 .

[0096] Furthermore, the bonding strength between the third adhesive layer 17 and the coating layer 13 is less than the bonding strength between the third adhesive layer 17 and the first release paper 11, so that when the first release paper 11 is separated from the coating layer 13, the second adhesive layer 16 is torn off together, while the separation of the coating layer 13 and the label layer 12 can be avoided.

[0097] Furthermore, the AB double-sided tape is a conventional setting well known to those skilled in the art and will not be described in detail.

[0098] In this embodiment, Figures 1 to 5 As shown, the number of printing units 1 in the printing paper is multiple, and the printing paper also includes a connecting line 2, which is set between two adjacent printing units 1 and is connected to the two adjacent printing units 1, as shown in FIG. Figure 4 、 Figure 5 As shown, the first areas 111 or the second areas 112 of the plurality of printing units 1 are alternately arranged in sequence along the winding direction, or as shown Figure 1 、 Figure 3 As shown, the first areas 111 or the second areas 112 of the plurality of printing units 1 are respectively arranged side by side in a direction perpendicular to the winding direction.

[0099] The two adjacent printing units 1 are connected to each other via a connecting line 2 to form an easily tearable connection structure.

[0100] Furthermore, the first areas 111 or the second areas 112 of the plurality of printing units 1 are alternately arranged in sequence along the winding direction, or the first areas 111 or the second areas 112 of the plurality of printing units 1 are arranged in parallel perpendicular to the winding direction.

[0101] In one embodiment, see Figure 8 、 Figure 9 The connecting line 2 is in a dot shape, so that a point-to-point connection is formed between two adjacent printing units 1.

[0102] By setting a point-to-point connection mode to connect two adjacent printing units 1 , it is convenient for the user to separate the unit to be printed 1 from the printed unit 1 after printing is completed.

[0103] Furthermore, the folding line 113 and the connecting line 2 are both dotted line connection structures for facilitating cutting by the user. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0104] Specifically, such as Figure 8 、 Figure 9 As shown, the two adjacent printing units 1 in the present device are connected by an "inverted triangle" or "horizontally arranged bracket-shaped" connection structure, so that the two adjacent printing units 1 only need to overcome the point-to-point connection and can be easily torn apart, which is convenient for user operation.

[0105] The utility model further provides a heat transfer label, comprising a roller 3 and printing paper, wherein the printing paper is wound around the roller 3 .

[0106] The printing paper is wound and rolled onto the roller 3, making it easy to unfold and use the printing paper in the printer.

[0107] Furthermore, the drum 3 is a conventional configuration well known to those skilled in the art and will not be described in detail here.

[0108] In order to better understand the present invention, the following Figures 1 to 9 The technical solution of the utility model is described in detail:

[0109] The printing paper includes at least one printing unit 1, which includes a first release paper 11, a label layer 12 and a coating layer 13. A first area 111 and a second area 112 are provided on the first release paper 11, and a fold line 113 is formed between the first area 111 and the second area 112. The label layer 12 and the coating layer 13 are respectively provided on the first area 111 and the second area 112. The side of the coating layer 13 facing away from the first release paper 11 is also provided with a first adhesive layer 15 for bonding to the label layer 12 and the coating layer 13 respectively. The edge of the first adhesive layer 15 is spaced apart from the edge of the first release paper 11. The coating layer 13 can be adhered to the label layer 12 through the first adhesive layer 15 when the first release paper 11 is folded along the fold line 113. Compared with the prior art, by providing a first adhesive layer 15 on the coating layer 13, the coating layer 13 can be adhered to the label layer 12, so as to provide coating protection for the label layer 12. At the same time, a spacing area 114 for the user to hold is formed between the edge of the first adhesive layer 15 and the edge of the first release paper 11, so as to avoid direct contact between the hand and the coating layer 13 or the adhesive layer on the label layer 12, and to avoid the influence of dust or hands on the viscosity of the hot melt glue layer.

[0110] The specific working process of the present invention is that when in use, the two adjacent printing units 1 can be easily separated by the connecting line 2, and then the second release paper 18 is torn off from the coating layer 13, and the spacing area 114 on the label layer 12 is held and the first release paper 11 is folded along the folding line 113, so that the coating layer 13 is connected to the printed information 14 and the label layer 12 through the first adhesive layer 15, and then the first area 111 or the second area 112 of the first release paper 11 is peeled off from the coating layer 13 or the printing layer, and the first area 111 or the second area 112 is cut off along the folding line 113, and finally the remaining second area 112 or the first area 111 of the first release paper 11 is peeled off from the coating layer 13 or the printing layer, and the user holds the spacing area 114 and sticks the formed coating layer 13, printed information 14 and label layer 12 on the product or object, avoiding or reducing the contact between the fingers and the hot melt glue layer, thereby avoiding or reducing the impact on the viscosity of the hot melt glue layer.

[0111] The above structure of the device can solve the technical problem in the prior art that fingers can easily come into contact with the glue, thereby affecting the viscosity of the glue and further affecting the bonding effect between the laminating area and the printing area, thereby reducing the effect of the laminating area in protecting the printing area.

[0112] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
