Metal security seals are designed to allow quick and efficient control, verification, for example, that unauthorized access to the meter, cargo, premises, etc. hasn’t taken place. However, metal seals are considered more secure than, for example, plastic seals, as they also provide the protective function and are equipped with various additional security solutions.
Metal seals are usually impossible to remove without the use of special tools. Metal seals are ISO certified, which further certifies that the manufacturer has developed metal seals with additional protection features.
