Zusammenfassung:The present invention belongs to the field of anti-fake packing technology, and is especially one anti-fake method utilizing thermal contraction film and random characteristic. The packing material of thermal contraction film with some pattern is used to pack matter in anti-fake mode and is heated according to the technological requirement, so that the thermal contraction film covers the packed matter closely. The random characteristic of the pattern in the contracted film and/or the relative position characteristic of the packed matter to the pattern are used as the anti-fake identification characteristic. The main advantages includes the hard-to-forge anti-fake characteristic and the anti-fake packing incapable of being reused.
