[0014] The moisture-proof layer is made of polyethylene film, and both sides of the heat-insulating layer are coated with heat-insulating paint.

[0015] By adopting the above technical solution, the polyethylene film can isolate water and prevent water from entering the self-adhesive label, and the heat insulation layer can isolate heat transfer from the external environment, thereby preventing the self-adhesive label from melting due to excessively high temperature and preventing the external environment from affecting the stickiness of the self-adhesive label.

[0016] The front side of the anti-oxidation layer is coated with an ultraviolet absorber, and a plurality of antioxidants are embedded in the anti-oxidation layer.

[0017] By adopting the above technical solution, the ultraviolet absorber in this solution can absorb ultraviolet rays emitted from the outside, and work together with the antioxidant to prevent food from oxidation, prolong the storage time of food, and extend the shelf life of food.

[0018] The size of the self-adhesive label body is smaller than that of the release paper, and easy-tear areas are arranged around the top of the release paper.

[0019] By adopting the above technical solution, the self-adhesive label body is located in the middle of the top of the release paper, and the easy-tear area can be bent downward to facilitate the removal of the self-adhesive label body, making the self-adhesive label body easy to remove and preventing damage to the self-adhesive label body.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The heat-insulating layer is coated with heat-insulating paint, which can isolate the heat transfer from the external environment, prevent the self-adhesive label from melting due to excessive temperature, ensure the stickiness of the self-adhesive label, and prevent the self-adhesive label from falling off. The anti-oxidation layer can prevent food from being oxidized and extend the storage time of food. The ventilation groove can exhaust air to prevent the existence of gas between the self-adhesive label and the adhered object, ensuring that the self-adhesive label is bonded smoothly.
