Tamper evident container seals its types and usage

Tamper Evident Container Seals- Its Types and Usage While transferring cargo in sealed containers, sometimes losses occur due to loss of stock, attributed to several isolated or linked causes, such as theft, adulteration, lack of accountability of vendors and service providers, weak cargo security mechanisms for goods in transit etc., which if not properly handled and addressed at root level, could severely damage business by creating insurmountable losses. To address this issue tamper evident seals are used to check against unauthorized intrusion for container goods in transits.

What are security seals and where are they used Security container seals are for sealing containers or equipment so that tamper evidence is provided, ensuring a tolerable amount of security, hence also referred to as tamper evident seals. When a device is tamper evident, it implies the device or mechanism has some way of detecting unauthorized access to protected spaces or equipment. A properly designed seal, attached properly as per specifications will have to be acutely disfigured before it can be broken. It is therefore a fairly inexpensive way of providing a certain degree of assurance against theft or unlicensed access.

These are used widely in airlines, transport and utility industries.

The mechanism used in tamper evident seal creation Various mechanisms are used in the tamper evident seal creation, like sealing, or electronically activated glass cabinet switches triggering alarm on intrusion based on fingerprints, software based keyloggers, etc.

However tamper evident seal scan be most effective, in terms of unsanctioned access detections, they should ideally not be stand alone systems, but need to be a part of an integrated security system as a whole which has multiple component for intrusion detections such as circuit connection to activate alarm, CCTV monitoring, software panic handling programs triggering protection device activation etc. The logic behind this being that, in a larger system if one device fails other devices can effectively provide alternate support for safeguarding purposes.

Different categories of container seals

There are several types of container seals, some of which are named below that have several built in mechanisms, asserting rock solid protection. These can be single use or reusable.

Single use container seals-This is generally made of plastic or metal- the material used and technology in production is the key to their security levels.

Reusable seal- These are generally electronic or plastic seals used in the transportation industry.

How to choose the right kind of seal In order to select the right type of seal one should have the proper knowhow on seal compatibility requirements with container types. Several related websites hosted on the net can also provide assistance in making a proper choice of container seals.

Limitation of seal usage Though seal usage has a substantial amount of advantages, in that they are rather inexpensive, lightweight, perform well under extreme environmental conditions, they can however, succumb to manipulations done by seal hackers, who can control and decode them rendering their safeguarding protection completely ineffective. To counter this, seal manufacturing companies should ensure special fortification in their tamper evidence container seal mechanisms, ensuring a manifold increase in safety assurance contained in the seal.
