Counterfeit, tamper and refill evident packaging

A method of packaging of a container comprising a mouth and a cap, the packaging comprising a shrink sleeve, a reference and a security label which comprises a pattern, the method comprising:

• disposing the security label either on the cap or the shrink sleeve;
• providing the reference on the other of the cap or the shrink sleeve, wherein the pattern and the reference are machine scannable;
• sealing of the cap by shrinking the shrink sleeve to cause the shrink sleeve to take a final shape, whereby as the shrink sleeve shrinks, one of the pattern and the reference provided on the shrink sleeve undergoes a change, as a result of shrinking of the shrink sleeve;
• generating a random spatial orientation of security label relative to the reference by shrinking the shrink sleeve to acquire the final shape, wherein the random spatial orientation is based on the final shape of the shrink sleeve and the changed pattern or the reference;
• and
• determining by a machine scan the spatial orientation of the security label relative to the reference, wherein the machine scan, based on the change in the spatial orientation, indicates tampering despite the same cap or a copy of the shrink sleeve being reapplied to the previously applied container or a different container.
