Description

Technical Field

[0001] The utility model relates to the technical field of labels, in particular to a label with a color-changing function. Background Art

[0002] Labels are used to mark and classify products. There are many types of labels. The express logistics industry has developed rapidly. However, during the express delivery process, personal privacy information is difficult to be well protected. The personal information printed on the express label on the express box, if not processed and thrown away directly, will cause the leakage of personal privacy.

[0003] Existing express labels generally use thermal paper labels. After the customer receives the express, it is necessary to use a lighter or other heating tool to bake and heat the thermal paper label for a certain period of time to destroy the protective layer of the outer layer of the label and change the color of the thermal coating through its characteristics, so as to process the personal information on the label. However, when using a lighter or other tool to heat the thermal paper label, the entire label cannot be heated at the same time. The label needs to be heated step by step, which is more troublesome. For this reason, we propose a label with a color-changing function. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a label with a color-changing function, which solves the problems raised in the above-mentioned background technology.

[0006] Preferably, the upper protective layer is composed of a hydrophobic film and an anti-ultraviolet layer, the anti-ultraviolet layer is arranged on the top of the thermal paper layer, and the hydrophobic film is arranged on the top of the anti-ultraviolet layer.

[0007] Preferably, the reaction package is composed of iron powder, activated carbon powder and salt materials.

[0008] Preferably, the hydrophobic membrane is composed of polyvinylidene fluoride, polytetrafluoroethylene, polyurethane, fluorocarbon resin, and special wax emulsion materials.

[0009] Preferably, the anti-ultraviolet layer is composed of an ultraviolet absorber.

[0010] Preferably, the adhesive layer is made of acrylic glue or rubber-based glue.

[0011] Preferably, the side of the anti-adhesive film in contact with the adhesive layer is coated with a silicone oil layer.

[0012] The utility model provides a label with a color-changing function, which has the following beneficial effects:

[0013] 1. The label with color-changing function, through the cooperation of the inner interlayer, the internal groove and the reaction package, can be used by the user to cut the thermal paper layer, the upper protective layer, the inner interlayer and the reaction package horizontally to expose the reactant inside the reaction package after receiving the express delivery, and then pour water into it to react and release heat, so that the thermal paper layer reacts and changes color, thereby covering the information on the label, so as to quickly achieve the purpose of erasing personal information, thereby improving the applicability of the label with color-changing function.

[0014] 2. The label with color-changing function cooperates with the anti-adhesive film and the drawstring, so that when sticking the label, the staff can tear off the anti-adhesive film by pulling the drawstring, thereby facilitating the sticking of the label with color-changing function, thereby improving the convenience of the label with color-changing function, and it is more convenient to use than the general label with color-changing function.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 3The utility model provides a technical solution: a label with a color-changing function, comprising a thermal paper layer 1, an upper protective layer 2 is arranged on the top of the thermal paper layer 1, an inner interlayer 3 is arranged on the bottom of the thermal paper layer 1, an adhesive layer 4 is arranged on the bottom of the inner interlayer 3, an anti-adhesive film 5 is arranged on the bottom of the adhesive layer 4, two corresponding draw tapes 6 are fixedly connected to the bottom of the anti-adhesive film 5, an inner groove 9 is opened inside the inner interlayer 3, and a reaction bag 10 is arranged inside the inner groove 9;

[0021] The upper protective layer 2 is composed of a hydrophobic film 7 and an anti-ultraviolet layer 8, the anti-ultraviolet layer 8 is arranged on the top of the thermal paper layer 1, and the hydrophobic film 7 is arranged on the top of the anti-ultraviolet layer 8;

When the iron powder water and the salt accelerate the exothermic oxidation reaction of the iron powder water under the catalysis of activated carbon, the reaction package 10 reacts and releases heat, so that the thermal paper layer 1 reacts and changes color, thereby covering the information on the label, thereby quickly achieving the purpose of erasing personal information. At the same time, the cooperation between the anti-sticking film 5 and the draw tape 6 makes it convenient for the staff to tear off the anti-sticking film 5 by pulling the draw tape 6 when sticking the label, thereby facilitating the sticking of the label with color-changing function.
