The utility model relates to the technical field of labels, and discloses a biodegradable anti-counterfeiting self-
adhesive label which comprises a base body, a
label is arranged on the surface of the base body, an anti-counterfeiting layer is arranged below the
label, the anti-counterfeiting layer is arranged on the surface of the base body, and transparent protective
layers are arranged on the surfaces of the label and the anti-counterfeiting layer in a heat sealing mode. And the end corner part of the base body is provided with a tearing opening. And the anti-counterfeiting layer is formed by printing a soybean-based
laser holographic pattern on the surface of the base material through a flexographic printing process, covering a layer of wood pulp
fiber fragile film and bonding through vegetable glue. The transparent protective layer comprises a base material, a waterproof layer is arranged on the top surface of the base material, and an anti-friction layer is arranged on the top surface of the waterproof layer. According to the biodegradable anti-fake self-
adhesive label, the anti-fake layer is covered with the transparent
protection layer, holographic patterns are prevented from being abraded or
printing ink fades, the waterproof layer prevents the label from losing
efficacy when encountering water, the anti-fake validity period is prolonged, and the label and the anti-fake layer can be prevented from being damaged by friction through the arranged anti-friction layer.
