These seals exist in various colors and are often equipped with a customizable tab that can receive a product name, a date or even a bar code for tracking. They are also particularly easy to install. Fixed seals have the same characteristics as adjustable seals, but it is impossible to control the length of the link.

Adhesive tapes and labels

Used by professionals, but also by individuals, adhesive strips and labels are devices that are sensitive to openings: they tear if handled.
