Description

Technical Field

[0001] This utility model relates to the field of label technology, and in particular to high-temperature resistant and anti-curling food printing labels. Background Technology

[0002] The existing label structure mainly consists of a top layer, an adhesive layer, and a bottom layer. The top layer carries printed text, patterns, barcodes, and other information, serving as an identifier and for advertising. The adhesive layer is used to attach the label to the surface of the object. The bottom layer protects the adhesive layer, preventing it from becoming contaminated or sticking before use. When used, these labels are prone to curling at the corners due to high temperatures, causing them to fall off. This is mainly because the expansion coefficients of the different layers of the label are inconsistent. When heated, thermal expansion generates internal stress. When this stress accumulates to a certain level, it causes the corners of the label to curl up to release some of the stress. Furthermore, because there is a small amount of air between the label and the object, this air expands at high temperatures. Since existing labels lack venting structures, this expanding air also causes the corners of the label to curl up, resulting in the label falling off. Utility Model Content

[0020] Working Principle: In this invention, functional layer 1 serves as heat insulation and reinforcement. In functional layer 1, the first elastic layer 11 and the protrusions 12 are an integral structure. The coefficient of thermal expansion of the first elastic layer 11 is greater than that of the second elastic layer 16. The first elastic layer 11 and the second elastic layer 16 form a composite structure similar to a bimetallic sheet. Therefore, in high-temperature environments, the first elastic layer 11 will bend towards the second elastic layer 16, and the protrusions 12 at its corners will apply pressure towards the object being labeled, thus preventing the corners from lifting. The second heat insulation layer 110 and the protrusions 112 are an integral structure. The second heat insulation layer 110 and the first heat insulation layer 15 are made of high-temperature resistant materials with a low coefficient of thermal expansion, such as polyimide, to block heat transfer. The gaps between the protrusions 112 allow air circulation, providing a certain heat dissipation effect. Furthermore, if air exists between the label and the object being labeled during label application, this air can be discharged through the gaps between the protrusions 112, preventing the label from lifting due to thermal expansion. The first serrated surface 13 and the second serrated surface 113 are used for attaching... The self-adhesive layer 2 increases the contact area with the self-adhesive layer 2, increasing the amount of self-adhesive adhered and preventing the label from falling off due to insufficient adhesive. The first adhesive layer 14 connects the first heat insulation layer 15 and the first elastic layer 11. The second adhesive layer 18 connects the second elastic layer 16 and the first elastic layer 11. The third adhesive layer 19 connects the second elastic layer 16 and the second heat insulation layer 110. The first notch 17 and the second notch 111 are used to accommodate the protrusion 12. The backing paper layer 3 protects the self-adhesive layer 2. The fourth adhesive layer 4... The fifth adhesive layer 7 is used to connect the printing layer 5 and the first heat insulation layer 15. The printing layer 5 is used to carry the ink layer 6, which contains the printed content. The fifth adhesive layer 7 is used to connect the ink layer 6 and the waterproof layer 8, which protects the ink layer 6. The first adhesive layer 14, the second adhesive layer 18, the third adhesive layer 19, the self-adhesive layer 2, the fourth adhesive layer 4, and the fifth adhesive layer 7 all use high-temperature resistant adhesives, such as acrylic self-adhesive. The ink layer 6 uses high-temperature resistant inks, such as silicone inks. The waterproof layer 8 uses a high-temperature resistant protective film, such as a fluoroplastic film.
