Forging proof seals that provide evidence of entry or contamination; barrier seal, used to prevent entry; and the most advanced is an electronic security seal which actively monitors for tampering and can send you real-time alerts in the event of a tamper.

Seals showing signs of tampering are simple seals such as breakable sheets or films, plastic packaging, pressure sensitive adhesive tapes, crimped cables or other immutable mechanical assemblies (about theoretical side). They are not designed to provide additional security, only to provide proof of tampering.

Barrier seals are devices or materials such as pressure seals, cable ties, padlocks, container seals and bolt seals that passively serve to prevent intrusion. When breached, they provide physical evidence of tampering (eg, broken belts or links, or a lack of tightness if removed completely).

THE MOST COMMON SECURITY SEAL TYPE IS PLASTIC SEAL USED FOR TRANSPORTATION SECURITY

Plastic seals are commonly used for transportation and short-term damage prevention measures. Plastic type of seals are very cost-efficient and if you consider security versus cost, you would choose a high security cable seal or bolt seal (container seal).

Cable seals are usually made of combination of metal & plastic with a permanently attached metal security wire. Taking advantage of the smoothness of cables, cable seals are often used in damage prevention measures where sealing is required.

High Security Seals are mostly made fully from the metal & metal wire and are designed to be intrusion resistant and comply with international customs standards and ISO security seals.

High security bolt seal (cargo seal) is usually A3 steel as the lock head and locking rod, heavy and durable. It is commonly used in theft prevention measures with long distances for container or truck sealing to provide security for a long period of time.

There is also a high demand for sealing electric meters, water meters, gas meters to insure damage prevention measures. The special utility security seals are used for utility meters sealing.
