Anti-theft label and label roll for roll machine

Abstract

The invention relates to an anti-theft label adhered by a rolling-up machine, which is provided with a substrate and a plurality of magnetizing and demagnetizing chips, wherein the substrate is formed by a cobalt-based amorphous soft magnetic material rapid-quenched sprayed ribbon; a plurality of magnetizing and demagnetizing chips are arranged at intervals and are made of half-hard magnetic materials; the widths of the magnetizing and demagnetizing chips are 0.5mm to 1.8mm; and the width of the substrate is 0.5mm to 1.8mm. The invention also relates to a label roll which is provided with a PET (polyethylene terephthalate) releasing film and a Glassine releasing film. The Glassine releasing film is provided with 5 to 15 anti-theft labels adhered by the rolling-up machine, which are arranged at equal intervals. The substrate is made of a cobalt-based amorphous soft magnetic material which has the strongest magnetic conductivity performance in the low frequency range of 1Hz to 15kHz and has wide application range, so that the electromagnetic wave anti-theft function of the label is guaranteed; meanwhile, the substrate is directly made of the rapid-quenched sprayed ribbon and the formed label is rarely influenced by an external force; the appearance of the label is in a slender shape and the label is smaller in width and beneficial for guaranteeing the confidentiality; and 5 to 15 labels in each group are adhered on the Glassine releasing film, are convenient for production packaging and are convenient to use.

Description

technical field [0001] The invention relates to an anti-theft electronic label and a label roll, in particular to an anti-theft label and a label roll for a rolling machine. Background technique [0002] Radio frequency identification technology has been widely used in many fields such as industrial automation and commercial automation, including transportation, manufacturing, waste management, mail tracking, air baggage checking and highway toll management, and radio frequency identification systems are often used to prevent Unauthorized removal of items from a protected area such as a library or retail store. [0003] RFID systems often include interrogation zones located near exits from protected areas to detect RFID tags attached to protected items. The tag then generates a signature response, communicates with the RFID reader, and if the communication reveals that the item has been taken without authorization, the RFID system initiates appropriate security measures, su...
