To seal a container or device, a sealing wire is attached in such a way that the container or device can no longer be opened without destroying the wire or the seal acting as a closure.
Sealing wire consists of a core made of brass or nylon (approx. 0.5 mm thick) with a spiral wrapping of another wire (brass, approx. 0.3 mm thick). The spiral wire prevents the sealing wire from being pulled out of the seal after it has been sealed.
