Problems solved by technology

Because it must be fixed on the bottle mouth with a bottle cap and pressed tightly before it can be used, the application range of the current electromagnetic induction aluminum foil sealing sheet is greatly limited, and it can only be used as a cover for horizontally placed bottle mouths. Inner caps, but cannot be used as a sign (lead) seal for seams in vertical or inclined situations, for example, it cannot be used as a sign (lead) seal for sealing the seam of the upper and lower caps of an upright liquor bottle

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).

Abstract

The invention relates to a sign (lead) sealing method of a product, in particular to a method of antitheft opening sign (lead) sealing the product by a self-adhesive label and an antitheft opening facing slip thereof. The invention applies self-adhesive lines or self-adhesive dots on the prior electromagnetic induction aluminum foil sealing film, the antitheft opening facing slip can be conveniently positioned on the product for lead sealing, and then, an electromagnetic induction heater is used for heating and solidifying, thereby achieving antitheft lead sealing. The invention is convenient for using, and is very reliable.

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...
