Abstract
Description
technical field
[0001] The invention relates to a label (lead) sealing method for a product, in particular to a method for anti-theft opening (lead) sealing of a product by using a self-adhesive label and the anti-theft self-adhesive label. Background technique
[0002] When existing self-adhesive labels are used as seals in the field of anti-theft (uncovering), they have encountered such a technical problem: counterfeiters use (such as with a hair dryer) heating method to heat and soften the self-adhesive and lose its cohesive force. , the label can be completely removed from the product, and then pasted on the counterfeit product, or, after the content of the product is exchanged (such as secretly replacing a high-end famous wine with a low-grade bad wine), the product that is still in good packaging can be sold to consumers . In order to overcome this technical problem, the inventor once suggested that a certain winery abandon the use of self-adhesive seals and use liqui...
Examples
Embodiment 1
[0042] As shown in Figure 1, purchase an electromagnetic induction aluminum foil sealing film roll with a thickness of 50 μm, a width of 220 mm, and a softening point of hot melt adhesive of 100 ° C, and place it in the RRP-230 hot melt adhesive spray coating machine On the unwinder, the glassine backing paper with a width of 225mm is passed around the pressure roller and the electromagnetic induction aluminum foil sealing film is bonded and rolled.
[0043] Start the machine, and spray a kind of hot-melt self-adhesive (also known as pressure-sensitive adhesive) strip on the hot-melt adhesive layer (2) of the electromagnetic induction aluminum foil sealing film, so that the width of each self-adhesive line is kept at 1 -2mm, adjust the distance between the nozzles, so that the self-adhesive lines (3) sprayed on the hot-melt adhesive layer (2) maintain a distance of 3-8mm, and then the self-adhesive electromagnetic induction aluminum foil sealing film can be produced. It is als...
Embodiment 2
[0051] As shown in Figure 5, purchase a kind of strong adhesive self-adhesive (also known as pressure-sensitive adhesive) trademark paper, print or compound the anti-counterfeiting label information layer (4) on it, and print a temperature-indicating color on a prominent position Block layer (13). In order to prevent the temperature-indicating color block layer (13) from becoming discolored and ineffective due to the influence of the ambient temperature during storage, it is best to select an irreversible temperature-changing ink with a discoloration temperature of 45-99°C. In this way, if the counterfeiter heats the self-adhesive label, the temperature-indicating color block layer (13) must change color, for example, from colorless to red. As long as the manufacturer prints notices such as "do not buy when a certain position turns red" on the product, counterfeiters must not dare to use heating to remove the self-adhesive anti-theft seal (5).
