• the present invention relates to an adhesive tamper evident label, for example an adhesive tamper evident vehicle registration label, an adhesive tamper evident label support, for example an adhesive tamper evident vehicle registration label support, a method for manufacturing the adhesive tamper evident label, and a method for manufacturing the adhesive tamper evident label support.
• Adhesive labels are used in many industries to, for example, label a variety of products such as for example foodstuffs, beverages, medicines, beauty products, etc. Many of these items include anti tamper devices such as seals which break if the item has been tampered with (ie. opened) without authorisation. This provides a clear warning to the consumer that the contents of the item are unsafe and should not be used. There is however a risk that counterfeiters are able to effectively remove the original label from an authentic product and replace the label on to a counterfeit product having a highly similar or identical appearance. This removal and replacement of the original label onto counterfeit products poses a risk for a consumer.
• Vehicle registration plates are increasingly copied or stolen from vehicles.
• the copied or stolen vehicle registration plates are commonly used to sell stolen cars, to disguise cars used in criminal activities (such as for example robberies or theft of fuel from a service station), or to evade speeding fines or parking fines or congestion charges.
• the owner of the vehicle registration plate may not realise that their vehicle registration plate has been copied until they receive numerous traffic offence penalty notices and charges for vehicle related incidents that they were not responsible for. This places the owner in the difficult position of having to prove that their vehicle was not involved in these instances.
