Description

Technical Field

[0001] The utility model relates to the technical field of thermal paper labels, in particular to a thermal label for cold chain. Background Art

[0002] Most of the labels referred to in the printing industry are printed materials used to identify the relevant descriptions of their own products, and most of them have self-adhesive on the back. However, there are also some labels without adhesive during printing, which can also be called labels. Labels with adhesive are commonly known as "self-adhesive labels", and existing labels mostly use ordinary label paper for printing, and cannot work in a low-temperature and high-humidity environment for a long time. Especially in the process of using a large number of logistics labels in supermarkets, shopping malls or express logistics, existing labels are prone to falling off or being damaged from the objects to be pasted, and cannot meet the actual needs. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above technical problems and propose a thermal label for cold chain.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] Design a thermal label for cold chain, including a protective film layer, a printing layer, a water-absorbing layer, a weather-resistant adhesive layer, and a release paper layer. The water-absorbing layer is arranged between the printing layer and the weather-resistant adhesive layer. Among them, the weather-resistant adhesive layer includes barrier adhesive strips arranged on both sides of the bottom surface of the water-absorbing layer and a plurality of reinforcing adhesive strips connecting the barrier adhesive strips. There is a water accumulation area formed between adjacent reinforcing adhesive strips, and the water accumulation area is communicated with the water-absorbing layer.

[0006] Further, the water-absorbing layer includes an upper paper, a water-absorbing resin layer, and a lower paper. The water-absorbing resin layer is arranged between the upper paper and the lower paper, and the lower paper is provided with through holes corresponding to the water accumulation area.

[0007] Further, the reinforcing adhesive strip has a connected wave crest section and wave trough section, and the water accumulation area is located between the opposite wave trough sections.

[0008] Further, the distance between adjacent reinforcing adhesive strips is 2-6 mm.

[0009] Further, the width of the barrier adhesive strip is 8-12 mm.

[0010] Further, the protective film layer is a polytetrafluoroethylene film.

[0011] A thermal label for cold chain proposed by the utility model has the following beneficial effects: By setting a weather-resistant adhesive layer, the use of blocking rubber strips and reinforcing rubber strips ensures firm bonding with the object to be pasted; through the cooperation of the water accumulation area and the water absorption layer, the water entering the weather-resistant adhesive layer is absorbed in the water absorption layer, preventing the label from falling off the object to be pasted in a low-temperature and high-humidity environment; by setting a protective film layer on the printing layer, the printing font on the printing layer is waterproofed, avoiding the font from being blurred due to moisture on the label surface and improving the actual use effect of the label.

[0015] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments.

[0016] Embodiment, refer to Figures 1 - 3 This is an embodiment of the present utility model, which discloses a thermal label for cold chain, including a protective film layer 1, a printing layer 2, a water absorption layer 3, a weather-resistant adhesive layer 4, and a release paper layer 5. The water absorption layer 3 is arranged between the printing layer 2 and the weather-resistant adhesive layer 4. In this embodiment, the printing layer 2 is implemented with thermal paper and is used for printing label information to achieve the function of final information identification and transfer. Among them, the weather-resistant adhesive layer 4 includes blocking rubber strips 401 arranged on both sides of the bottom surface of the water absorption layer 3 and a plurality of reinforcing rubber strips 402 connecting the blocking rubber strips 401. A water accumulation area 403 is formed between adjacent reinforcing rubber strips 402, and the water accumulation area 403 is communicated with the water absorption layer 3.

[0017] The utility model ensures firm bonding with the object to be pasted by setting the weather-resistant adhesive layer 4 and using the blocking rubber strips 401 and the reinforcing rubber strips 402; through the cooperation of the water accumulation area 403 and the water absorption layer 3, the water entering the weather-resistant adhesive layer 4 is absorbed in the water absorption layer 3, preventing the label from falling off the object to be pasted in a low-temperature and high-humidity environment; by setting the protective film layer 1 on the printing layer 2, the printing font on the printing layer 2 is waterproofed, avoiding the font from being blurred due to moisture on the label surface and improving the actual use effect of the label.

[0018] In an alternative embodiment of the present utility model, the water-absorbing layer 3 includes an upper layer of paper 301, a water-absorbing resin layer 302, and a lower layer of paper 303. The water-absorbing resin layer 302 is disposed between the upper layer of paper 301 and the lower layer of paper 303. The lower layer of paper 303 is provided with through holes 3031 corresponding to the water accumulation area 403. Preferably, the upper layer of paper 301 and the lower layer of paper 303 in this embodiment can be implemented using coated paper or matte paper. The water in the water accumulation area 403 enters the water-absorbing resin layer 302 through the through holes 3031 and is absorbed by the water-absorbing resin layer 302, thereby absorbing the water entering the weather-resistant adhesive layer 4 within the water-absorbing layer 3 and preventing the label from peeling off the adherend in a low-temperature and high-humidity environment.

[0019] In an alternative embodiment of the present utility model, the reinforcing adhesive strip 402 has a connected wave crest section 4021 and a wave trough section 4022. The water accumulation area 403 is located between opposite wave trough sections 4022. The settings of the wave crest section 4021 and the wave trough section 4022 make the reinforcing adhesive strip 402 wavy, which can guide the water entering the weather-resistant adhesive layer 4 and concentrate the water in the water accumulation area 403, facilitating the absorption of water by the water-absorbing layer 3.

[0020] In an alternative embodiment of the present utility model, the spacing between adjacent reinforcing adhesive strips 402 is 2 - 6 mm. The reinforcing adhesive strips 402 are distributed in a wavy pattern on the bottom surface of the water-absorbing layer 3. The spacing between two adjacent reinforcing adhesive strips 402 is between 2 - 6 mm, which can reduce the usage amount of the weather-resistant adhesive and is more environmentally friendly.

[0021] In an alternative embodiment of the present utility model, the width of the blocking adhesive strip 401 is 8 - 12 mm. Preferably, the length of the blocking adhesive strip 401 in this embodiment is the same as that of the label. The setting of the blocking adhesive strip 401 ensures the connection strength between both sides of the label and the adherend.

[0022] In an alternative embodiment of the present utility model, the protective film layer 1 is a polytetrafluoroethylene film.

[0023] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
