Type of Security Seals and Their Uses in Various Industries

Security seals are tamper-evident mechanisms used in various containers or bags for security purposes. They are one of the essential parts of the shipping container or bags containing high-value goods. They minimize the risk of someone opening the container and hence avoids theft. In addition, they play a crucial role in maintaining global security by acting as a barrier for anyone to put illegal items like dangerous weapons, drugs, etc., in the container.

Content piracy is big. It’s costly. And it’s a growing ROI problem for content owners and distributors across the globe. Unlike previous, closed systems, today’s digital delivery system makes it easier for pirates to steal and re-stream illegal content anywhere in the world, using the same type of infrastructure used by the service providers themselves.

There are many types of security seals manufactured with Advanced Technology to meet the standards established by ISO. Different types of security seals find applications in various places; they can be bolt seal for cargo containers or container seal for truck doors. Here we have listed some of the most common types of security seals–

Bolt Seals

Bolt seals are high-security seals that are mainly used for containers and trailer doors. They have a complex lock mechanism with a manually attached metal bolt and a temper evident part. Most of the bolt seals have a self-lock tool which makes it easy to lock the seal. They are difficult to remove and require a bolt cutter for removing. Bolt seals ensure high security to the containers from theft or piracy by carrying permanent laser marking on the bolt locks. The bolt locks find their application not only in shipping or inter-modal containers but also in ground transportation. Bolt seal for cargo containers is a common application of it.

Container Seals

Container seal is one of the most used seals which ensure the security of the shipping containers. The bush and the pin of the container seals are manufactured with high-quality material, making them durable. Good Container Seals have laser marking of the serial number, barcode, etc., which makes it difficult to remove or replace. Container seal finds their application in various places like truck doors, trailer doors, railcar doors, totes, coin bags, etc. These seals are primarily used in international shipping containers and are an essential requirement for shipping.

Cargo Seals

Cargo seals are a type of security seals that are generally used in international cargo. The cargo seal is made of high-quality raw material so that it can serve its purpose correctly. This seal also the laser marking features that allow the company name or logo to be printed on the seal. They find applications in airline cargo, tote boxes, roll cages, bank, and postal services, etc.

High Security Seals

High security seals are one of the significant types of security seals used when the greatest level of protection is required. To make the lock highly durable, they are made of optimum quality materials like carbon steel. Like other security seals, they also contain laser printing of serial number, name, barcode, etc., which is unremovable. They are primarily used for protecting high valued goods, and their application can be in truck doors, tankers, heavy-duty boxes, money bags, etc.

Luggage Seals

Luggage seals are yet another type of security seal that are mainly used in bags. Modern technology has allowed the manufacture of high-quality luggage seals, which effectively ensure the security of the bags. Luggage seals can be used in many places; some of the applications include- postal services, airline cargo, roll cages, clinical waste management, courier services, cash-in-transit, etc.

Wire Seals

Wire seals use metal wires in places where the seals need to fit through a small opening. The wire used in these types of seals is highly durable and has very little chance of breaking. They can be easily sealed by hand, but it needs a cable cutter for removing. Wire seals come with laser printing which carries the name, logo, serial number, or barcode. They are another most used seals which find their application in truck doors, trailer doors, heavy-duty boxes, tankers, etc.

Plastic Seals

Plastic seals are generally of two types, namely adjustable or fixed-length plastic seals. Adjustable seals are used for securing locks, and they mainly find their application in places like bags, chemical drums, fire extinguishers, first aid kits, etc. Some of these seals can carry bar codes, company names, serial numbers, etc., to provide more security. At the same time, fixed-length plastic seals are more temper resistant and easier to fit. These seals are mainly used in transport applications. Plastic seals can also be used in bank bags, postal services, airline cargo, clinical waste, courier services, etc.

Iron Seals

Iron seals are a type of security seals that are mainly used in containers acting as a barrier. Once the seal is locked, it requires a cutter to open it. Since the seal remains locked till it is cut, it ensures that the containers reach their destinations without anyone opening it in the way. Like bolt seal for cargo containers, they protect the container’s content from any kind of illegal intervention.
