Product definition and development history 1. Product definition In order to prevent goods from being stolen and stolen during transportation, "seals" are created accordingly. The traditional seal lock, also known as the mechanical seal, is installed before the container is transported. Regardless of the handling of different roles in the supply chain and the stay at multiple locations, when the container is unloaded, the integrity of the container can be immediately judged, and the carrier can handle the delivery procedures to complete the business. Traditional seals can be divided into container seals, court seals and security seals according to their different uses; It can be divided into paper seals, plastic seals, metal seals and electronic seals according to different materials. 2. Development history
Because the authenticity of traditional seals is too high, it often causes heavy losses, and some losses are even far higher than that without seals, causing a lot of trouble. Therefore, in order to seek better security and quality, people gradually evolved various anti-counterfeit seals, and the anti-counterfeit seals evolved electronic seals with the rapid development of science and technology.
Analysis of product characteristics and application fields 1. Classification of seals (1) According to the person who applies the seal, it can be divided into: factory seal (factory seal, which is added by the export factory); Customs lock (customs seal, that is, the customs seal is added by the customs); Ship seal (ship company seal, which is added by the ship company); Temporary seal of the wharf (temporary seal of the wharf is added by the wharf). (2) According to the material and function of the seal strip, it can be divided into: high security seal, digital anti-theft seal, bullet seal, iron sheet seal, steel wire plastic seal, plastic seal, anti-theft lead seal, ordinary seal, etc. 2. Application field The safety seals are widely used in containers, cash boxes, meter boxes, bonded vehicles, ammunition boxes and other safety protection systems. Foreign trade commodity inspection, containers, ships, domestic air transportation, international air transportation, logistics companies, shipping companies, transportation and handling equipment, transportation product processing, and enterprise product inspection, packaging barrel packaging, energy measurement, prevention of theft, leakage and sealing.
