Security seals are small, tamper-evident devices used to close shipping containers on shipping lines in such a manner that gives some degree of security and also Tamper evident security. These devices can help to detect contamination or theft, either intentional or accidental. A security seal is a thin transparent plastic film that is attached to the lid of a shipping container, and which can be peeled off to reveal the contents inside.
Such a device needs to give some form of protection against both light and sound, as they may not necessarily prevent tampering if the container is broken into, but can also provide sufficient security by preventing other containers from being opened and breaking open seals that have been placed on top of them. Security seals have been designed so that they can be applied to a wide range of containers. Containers can be made to be compliant with these special types of seals, or else a suitable alternative such as double sealed plastic film can be used instead.
Containers need to be
appropriately designed so that they meet the security requirements set out by
the law. It is also important for containers to comply with the various
international regulations relating to shipping. The most common types of security seals available are mechanical and electrical.
Mechanical seals are those that use high-tech adhesives to apply to the containers. In this case, a metallic channel is used to apply the seal to the lid, so that it cannot be peeled off. This type of security seal is the preferred type used, as it is the most secure, and it has a high level of tensile strength. Electrical security seals are used when containers are required to be compliant with certain energy efficiency standards.
