A destructible label or decal is usually produced from a very thin plastic, and once applied, is virtually impossible to remove in one piece. Destructible labels usually flake-off in tiny pieces when they are tampered with. They are designed to discourage unauthorized tampering with or transferring of labels, and also show any attempts to do so. See Tamper Evident.
