What is the point of having a tamper-evident label on a food product? Well put simply it will tell the customer or storekeeper that the product could have been interfered with and should be withdrawn from sale. A standard paper or file with a permanent adhesive may meet many customers’ requirements. However, in more demanding applications, special tamper-evident materials are available.
In most cases special shapes, label security cuts and materials that fracture easily are all in common use to ensure the product has not been interfered with in any way, in other cases, for electronic equipment usually for warranty purposes, tamper-evident labels that offer special synthetic seals which carry a void message should they be peeled away can be supplied or it is possible to use a destructible viny which disintegrates when any attempt is made to remove it.
Tamper proof labels are a vital part of safely packaging a product, or ensuring that a warranty has not been violated through the unauthorised opening of the electronic equipment.
