Container seals can be categorized based on their design, application, and security features. Here are the main types:
1. Plastic Seals: These are commonly used for securing containers like bags and boxes. They can be simple pull-tight seals or more complex designs with locking mechanisms.
2. Metal Seals: Often used in industrial applications, metal seals provide a higher level of security. They are typically made from aluminum or steel and can include bolt seals and cable seals.
3. Tamper-Evident Seals: These seals show visible signs of tampering when removed or broken, providing assurance that the container has not been opened. They can be plastic or metal and are used in various applications, including shipping and pharmaceuticals.
4. Bolt Seals: These are high-security seals used for securing shipping containers. They consist of a bolt that locks into a fitting and can only be removed with specific tools.
5. Cable Seals: Made from a strong cable, these seals can be used to secure larger containers and provide a high level of security. They are often used in transportation and logistics.
6. Lead Seals: Traditionally used in various industries, lead seals are crimped onto the container and provide tamper evidence. They are commonly seen in utilities and transport.
7. Shipping Container Seals: Specifically designed for cargo containers, these seals are robust and often incorporate features for tracking and security.
8. Security Labels: These adhesive labels provide tamper evidence and are often used on boxes or packaging. If removed, they leave a mark or a message indicating tampering.
