preparation example Construction

[0042] Another embodiment of the present invention provides a method for preparing an acoustomagnetic anti-theft label, including the following steps:

[0043] Selecting a paper part, and performing hot molding on the paper part to prepare a paper main casing 1 with a cavity and an opening on one side;

[0044] Put at least one resonant plate 2 into the cavity, and cover the one side of the main casing 1 with a paper sealing cover 3;

[0045] The bias piece 4 is arranged on the side of the sealing cover 3 away from the main casing 1 .

[0046]Another embodiment of the present invention provides a product package, which includes a product package body and the acoustomagnetic anti-theft label as described in any of the above solutions arranged on the product package body.

[0047] Specifically, the product packaging body is made of paper.

[0048] More specifically, the paper of the product packaging body is corrugated paper.

Embodiment 1

[0051] Choose single-sided PE-coated white cardboard with a thickness of 250 grams per square meter and a thickness of about 0.3mm-0.35mm, and make it into a roll. After humidification and steam heating, the paper The PE coated surface is then subjected to a hot molding process to prepare a paper-based shell of an acoustic-magnetic anti-theft soft label with a cavity structure.

[0052] Put a piece of resonant plate 2 into the shell cavity of the manufactured acoustic-magnetic anti-theft label, and then apply a single-sided PE film with a unit weight of 80 grams per square meter and a thickness of 0.1mm-0.15mm. The white cardboard is used as the material of the sealing cover 3. After the PE coated surface of the shell and the PE coated surface of the sealing cover 3 are heat-sealed at 130°C, the offset sheet 4 is double-coated with water-based acrylic adhesive. The surface adhesive 5 is fixed on the outer end of the sealing cover 3, and then covered with the double-sided adhes...

Embodiment 2

[0054] Select single-sided PE-coated coated paper with a thickness of 250 grams per square meter and a thickness of about 0.3mm-0.35mm, and make it into a roll. After humidification and steam heating, the paper will The PE coated surface is then subjected to a hot molding process to prepare a paper shell for an acoustic-magnetic anti-theft soft label with a cavity structure.

[0055] Put four resonant pieces 2 into the shell cavity of the manufactured acoustic-magnetic anti-theft label, and then pour a single-sided PE with a thickness of 0.1mm-0.15mm and a unit weight of 80 grams per square meter. Film coated paper is used as the material of the sealing cover 3. After the PE coated surface of the shell and the PE coated surface of the sealing cover 3 are heat-sealed at 160°C, the offset sheet 4 is glued on both sides of the water-based polyurethane adhesive. The glue 5 is fixed on the outer end of the sealing cover 3, and then covered with the double-sided glue 5 and the separ...

Abstract

The invention discloses an acoustic-magnetic anti-theft label, a shell of the acoustic-magnetic anti-theft label, a preparation method of the acoustic-magnetic anti-theft label, a version label, a volume label and a product package. A cavity used for containing a resonance piece is formed in the shell. At least part of the shell is made of paper. According to the acoustic-magnetic anti-theft label shell, at least part of the acoustic-magnetic anti-theft label shell is made of paper, the use amount of plastic of an existing acoustic-magnetic anti-theft label shell is reduced or eliminated, and therefore accumulative plastic pollution caused by just-needed consumables widely used in the global retail industry can be reduced or eliminated. In addition, the water-based adhesive adopted in the invention can replace oily adhesive in a traditional acoustic magnetic anti-theft label, and a more environment-friendly solution is further provided for the use of the adhesive in the manufacturing process of the acoustic magnetic anti-theft label.

Description

technical field [0001] The invention relates to the field of anti-theft technology, in particular to an acousto-magnetic anti-theft label, its casing, a preparation method, a plate label, a roll label and product packaging. Background technique [0002] The existing acoustic and magnetic anti-theft soft label is composed of PS (polystyrene) / PE plastic composite shell film, non-wafer, semi-hard magnetic sheet, sealing cover material PE / PET plastic composite film, self-adhesive paste paper and other multi-layer structures. Composition, paste it on the product packaging, and use acoustic magnetic resonance technology to achieve anti-theft, and it is widely used in retail supermarkets, shopping malls, chain stores and other places around the world. Customers can pay for degaussing at the cash register after selecting the product. If the thief tries to take the product out of the store without paying, the tag will trigger an alarm when the product passes through the sound and mag...
