Traditional clamping seal: This is the earliest sealing method used, through the clamping of metal wires for blocking.
Plastic locking seal: It is made of special material, non-toxic and with toughness, and it is pressed in by special tools or directly by hand after threading manually.
Electronic seals: Combined with RFID chip technology, they have uniqueness, encryption function and anti-counterfeiting function.
Characteristics and uses of each type of seals
Traditional clamp-pressing type seals: this kind of seals is blocked by clamping the metal wires, which is simple to operate but easy to be forged and destroyed, mainly used for early meter blocking.
Plastic locking type seals: they are made of special materials, non-toxic and tough, and can be anti-counterfeiting through laser engraving, numbering, manual labeling and other ways, with strong anti-electricity theft function.
Electronic seals: Combined with RFID chip technology, each RFID chip has a globally unique serial number with non-replicable uniqueness, strong encryption and non-destructive anti-counterfeiting features, widely used in water meters, electricity meters, gas meters and other instruments of digital sealing.
