Description

Technical Field

[0001] The utility model relates to the technical field of coated paper, and more specifically, to a double-layer coated paper. Background Art

[0002] Coated paper, a commonly used printing paper in the printing industry, includes double-layer coated paper and single-layer coated paper. Double-layer coated paper has the characteristics of high whiteness, good ink absorption and ink retention, and the ability to perform double-sided printing. It is often used for printing high-end albums, calendars, books and other items.

[0003] Existing double-layer coated paper is usually placed and stacked in a warehouse when stored in batches. However, after being stored for a long time, the double-layer coated paper will be affected by the temperature and humidity in the warehouse, causing the double-layer coated paper to age, resulting in yellowing or mildew on the surface of the double-layer coated paper, which shortens the service life of the double-layer coated paper.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a double-layer coated paper, which solves the problem that after the double-layer coated paper is stored for a long time, the double-layer coated paper will age, causing yellowing or mildew on the surface of the double-layer coated paper, which affects the service life of the double-layer coated paper.

[0006] The above technical purpose of the present utility model is achieved through the following technical scheme: a double-layer coated paper, including a coated paper body, and also including a protective layer wrapped on the coated paper body, the protective layer and the coated paper body are bonded to each other, the two sides of the protective layer are detachably connected to each other, a cavity is opened in the protective layer, and a drying layer is fixedly connected in the cavity.

[0007] By adopting the above-mentioned structural arrangement, when double-layer coated paper needs to be stored in batches, the coated paper body is placed on the protective layer, and then the protective layer is driven to fold over and wrap the coated paper body, and then the two sides of the protective layer are installed to each other. At this time, the coated paper body cannot be separated from the protective layer, thereby achieving the effect of protecting the double-layer coated paper. Through the provision of the protective layer, the coated paper body can be isolated from the outside world, and the outside temperature is reduced to contact the coated paper body. At the same time, the provision of the drying layer can be used to isolate the outside humidity, thereby slowing down the aging speed of the double-layer coated paper and increasing the service life of the double-layer coated paper. When the double-layer coated paper needs to be used, it is only necessary to remove the two sides of the protective layer from each other to remove the coated paper body from the protective layer, so as to avoid affecting the subsequent printing effect of the double-layer coated paper. At the same time, the removed protective layer can also be recycled and reused to wrap another double-layer coated paper, thereby improving the environmental protection effect.

[0008] The utility model is further configured as follows: a connecting piece is fixedly connected to the protective layer, a limiting block is fixedly connected to one side of the connecting piece, a limiting groove for inserting the limiting block is opened on the protective layer, and the connecting piece and the limiting block both have deformation capabilities.

[0009] By adopting the above-mentioned connection piece and limiting block, when installing the two sides of the protective layer, the protective layer is driven to fold over, and the protective layer and the coated paper body are brought into contact with each other. Then the limiting block is inserted into the limiting groove. At this time, the two sides of the protective layer are affected by the limiting block and cannot be separated from each other, thereby achieving the effect of installing the two sides of the protective layer. At the same time, the connection piece and the limiting block have the characteristics of deformation ability, which can prevent the connection piece and the limiting block from affecting the curling of the double-layer coated paper on the paper tube.

[0010] The utility model is further configured as follows: a groove for inserting the protective layer is opened on the side wall of the limiting block; when the protective layer is inserted into the groove, the protective layer and the coated paper body are in contact with each other.

[0011] By adopting the above groove arrangement, the fixing effect between the limiting block and the limiting groove can be improved, thereby preventing the limiting block from accidentally separating from the limiting groove.

[0012] The utility model is further configured as follows: an electrostatic layer is fixedly connected to a side of the protective layer close to the coated paper body.

[0013] By adopting the above-mentioned electrostatic layer setting and utilizing the electrostatic induction phenomenon generated by the electrostatic layer, the protective layer and the coated paper body can be more closely attached, reducing the entry of external air between the protective layer and the coated paper body, further slowing down the aging speed of the double-layer coated paper and increasing its service life.

[0014] The utility model is further configured as follows: the drying layer includes a plurality of moisture-absorbing strips located in the cavity; a heat-insulating layer is fixedly connected to one side of the cavity close to the coated paper body; and the heat-insulating layer and the plurality of moisture-absorbing strips are fixedly connected.

[0015] By adopting the above-mentioned moisture-absorbing strips and the setting of the heat-insulating layer, the setting of several moisture-absorbing strips can absorb the water vapor that penetrates into the cavity, keep the inside of the cavity dry, and prevent water vapor from penetrating through the cavity to the coated paper body. The setting of the heat-insulating layer can effectively isolate the paper from the external temperature, slow down the aging speed of the double-layer coated paper, and increase its service life.

[0016] The utility model is further configured such that when the limiting block is inserted into the groove, the bottom of the limiting block and the coated paper body are in contact with each other.

[0017] By adopting the above-mentioned state setting, the fixing effect between the limiting block and the limiting groove can be improved, and at the same time, the outside air can be prevented from entering between the limiting block and the coated paper body, further slowing down the aging effect of the double-layer coated paper and improving its service life.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. After the double-layer coated paper is stored for a long time, the protective layer can be set to isolate the coated paper from the outside world, reduce the outside temperature and prevent it from coming into contact with the coated paper. At the same time, the drying layer can be set to isolate the outside humidity, thereby slowing down the aging speed of the double-layer coated paper and increasing its service life.

[0020] 2. When double-layer coated paper is needed, you only need to remove the two sides of the protective layer from each other to remove the coated paper body from the protective layer, so as to avoid affecting the subsequent printing effect of the double-layer coated paper. At the same time, the removed protective layer can also be recycled and reused to wrap another double-layer coated paper, thereby improving environmental protection.

[0029] A double-layer coated paper, such as Figure 1-Figure 4As shown, it includes a coated paper body 1 and a protective layer 2 wrapped on the coated paper body 1. The protective layer 2 and the coated paper body 1 are attached to each other, and the two sides of the protective layer 2 are detachably connected to each other. A cavity 3 is opened in the protective layer 2, and a drying layer is fixedly connected in the cavity 3. When it is necessary to store double-layer coated paper in batches, the coated paper body 1 is placed on the protective layer 2, and then the protective layer 2 is folded and wrapped around the coated paper body 1, and then the two sides of the protective layer 2 are installed to each other. At this time, the coated paper body 1 cannot be separated from the protective layer 2, thereby achieving the effect of protecting the double-layer coated paper. The provision of the protective layer 2 can isolate the coated paper body 1 from the outside world, reduce the outside temperature from contacting the coated paper body 1, and at the same time, the provision of the drying layer can isolate the outside humidity, thereby slowing down the aging speed of the double-layer coated paper and increasing the service life of the double-layer coated paper. When the double-layer coated paper is needed, it is only necessary to remove the two sides of the protective layer 2 from each other to remove the coated paper body 1 from the protective layer 2, thereby avoiding affecting the subsequent printing effect of the double-layer coated paper. At the same time, the removed protective layer 2 can also be recycled and reused to wrap another double-layer coated paper, thereby improving the environmental protection effect.

[0030] like Figure 1-Figure 4 As shown, a connecting piece 4 is fixedly connected to the protective layer 2, and a limiting block 5 is fixedly connected to one side of the connecting piece 4. A limiting groove 6 for inserting the limiting block 5 is opened on the protective layer 2. The connecting piece 4 and the limiting block 5 both have deformation capabilities. When installing the two sides of the protective layer 2, the protective layer 2 is driven to fold over, and the protective layer 2 and the coated paper body 1 are brought into contact with each other. Then the limiting block 5 is inserted into the limiting groove 6. At this time, the two sides of the protective layer 2 are affected by the limiting block 5 and cannot be separated from each other, thereby achieving the effect of installing the two sides of the protective layer 2. At the same time, the connecting piece 4 and the limiting block 5 have the characteristics of having deformation capabilities, which can avoid the connecting piece 4 and the limiting block 5 from being deformed. Block 5 affects the curling of the double-layer coated paper on the paper tube, and a groove 7 for inserting the protective layer 2 is opened on the side wall of the limiting block 5. When the protective layer 2 is inserted into the groove 7, the protective layer 2 and the coated paper body 1 contact each other, which can improve the fixing effect between the limiting block 5 and the limiting groove 6, and avoid the limiting block 5 from accidentally separating from the limiting groove 6. When the limiting block 5 is inserted into the groove 7, the bottom of the limiting block 5 and the coated paper body 1 fit together, which can improve the fixing effect between the limiting block 5 and the limiting groove 6, and at the same time prevent outside air from entering between the limiting block 5 and the coated paper body 1, further slowing down the aging effect of the double-layer coated paper and improving its service life.

[0031] like Figure 2 and Figure 3As shown, the side of the protective layer 2 close to the coated paper body 1 is fixedly connected to an electrostatic layer 8. The electrostatic induction phenomenon generated by the electrostatic layer 8 can make the protective layer 2 and the coated paper body 1 fit more closely, reduce the outside air from entering between the protective layer 2 and the coated paper body 1, further slow down the aging speed of the double-layer coated paper, and improve the service life.

[0032] like Figure 2 and Figure 3 As shown, the drying layer includes a plurality of moisture-absorbing strips 9 located in the cavity 3, and a heat-insulating layer 10 is fixedly connected to the side of the cavity 3 close to the coated paper body 1. The heat-insulating layer 10 and the plurality of moisture-absorbing strips 9 are fixedly connected. By utilizing the arrangement of the plurality of moisture-absorbing strips 9, the water vapor penetrating into the cavity 3 can be absorbed to keep the interior of the cavity 3 dry, and prevent the water vapor from penetrating into the coated paper body 1 through the cavity 3. By providing the heat-insulating layer 10, the external temperature can be effectively isolated, the aging speed of the double-layer coated paper can be slowed down, and the service life can be increased.

[0033] The working principle of the present invention is as follows: when double-layer coated paper needs to be stored in batches, the coated paper body 1 is placed on the protective layer 2, and then the protective layer 2 is driven to fold over and wrap the coated paper body 1, and then the two sides of the protective layer 2 are installed on each other. At this time, the coated paper body 1 cannot be separated from the protective layer 2, thereby achieving the effect of protecting the double-layer coated paper. When the double-layer coated paper needs to be used, it is only necessary to remove the two sides of the protective layer 2 from each other to take out the coated paper body 1 from the protective layer 2. Through the setting of the protective layer 2, the coated paper body 1 can be isolated from the outside world, reducing the outside temperature from contacting the coated paper body 1. At the same time, the setting of the drying layer can isolate the outside humidity, thereby slowing down the aging speed of the double-layer coated paper and increasing the service life of the double-layer coated paper.
