General Classification of Seals

Simple security seals

These seals are made of materials that can be easily cut by hand or with simple tools such as scissors.

Security seals

Such seals are made of materials that have limited resistance to tampering and require tools to remove them.

High security seals:

The seal is made of materials such as metal or metal cable to delay manipulation. High security seals should generally be cut with heavy cutting tools.

The physical strength of seals is determined by tensile, shear, flexure and impact tests.
