What Are Security Seals?

Security seals are any of a number of mechanisms used to seal containers with some level of security. By design, security seal styles are tamper-evident, making it easy for users to detect theft and/or accidental or deliberate contamination of the container’s contents.

Security seals can be used to seal nearly any container that allows for locking or sealing. These include truck trailers, vessel containers, drums or barrels, and utility meters, among many others.

Types of Security Seals

Security seals come in a range of styles. The right security seal for a given application depends on the security requirements of the goods being secured.

  • For smaller and/or less valuable items, such as medical carts and courier bags, lightweight plastic beaded security seals are often preferred. These security seals provide tamper-evident security, but still allow the receiver to easily cut the seal with scissors.
  • For larger and/or more valuable items, including freight containers and high security totes, sturdy plastic or metal security seals offer the same tamper-evident safety with a seal that requires either cable or bolt cutters to remove.

Dual Purpose Security Seals

Security seals are commonly used on shipping containers, air freight containers, railroad containers, and the like to provide tamper-evident security for products and cargo in transit. Security seals serve two distinct purposes:

  1. Secure & Seal: The basic purpose of security seals is to fasten containers and packages to prevent unauthorized access. Shipping and freight containers commonly make use of security seals to prevent theft of and tampering with the contents. In this regard, security seals are similar to locks, except they don't require a key or combination to open them. They are intended to be disposable, as they are simply cut off after delivery.
  2. Tamper Evidence: The secondary purpose of security seals, and where they offer additional security beyond that provided by standard locks, is to provide evidence of any tampering. Security seals can typically only be removed by cutting them off. While locks can be opened and later replaced, security seals cannot be reattached after being opened. Additionally, security seals are often numbered so that, even if the seal is cut off and replaced with an identical seal, the number will be different, providing evidence of tampering.
