Traditional Lead Seals

The traditional type is the lead seal. These seals are approximately 5 mm thick and available in two diameters: 8 mm and 10 mm. Commonly used for sealing gas, water, and electricity meters, the wire is threaded through the seal and then crimped using a sealing tool to create a secure lock. Supplied in 1 kg bags, these seals provide a sturdy and tamper-evident solution where reliability is key.

Plastic Seals

Plastic lead seals offer a modern alternative to traditional lead versions. Made of high-quality polystyrene, they come in a standard 9 mm diameter and are available in vibrant colors like red, yellow, green, and orange, as well as neutral tones such as black, white, and grey. This color-coding enhances visibility and facilitates identification, supporting better seal traceability and monitoring.

Aluminium Seals

Aluminium seals are ideal for fast and tool-free application. Unlike traditional lead seals, no sealing pliers are required; the seal simply clicks shut by hand. This makes them especially useful in settings where frequent sealing is needed or tools are not readily accessible. The quick application enhances workflow efficiency.

Roll Tin Seals

Roll Tin Seals are commonly used in the Belgian market and by Dutch customs authorities. These seals require a specialized sealing tool, where the sealing wire is inserted and the seal is closed by rolling it tight. Tinplate seals are ideal for scenarios requiring extra assurance, ensuring that breaking the seal can only be done through controlled and visible action.

Custom Logo or Engraving

For enhanced traceability and protection against tampering, lead seals can be customized with engraved logos or short text (up to six characters). The engraving is applied to the die of the sealing tool and pressed into the seal during application. This personalization makes each seal unique and helps prevent fraud or substitution.
