Customised Dual Layer Label Lock™ security labels provide maximum security, delaminating on tampering or removal in a unique way to leave a permanent evidence of the seal.

With a minimum order quantity of just 12,000 labels you can customise the size, colour and design of a batch of your own unique Dual Layer Label Lock labels including a customised subsurface “opened” message in any language and text. The unique Dual Layer tamper evident technology that makes Label Lock so special is the same as the stocked version available off the shelf from your distributor with identical levels of tamper evident security. Special high security features such as temperature indicating thermochromic inks are available.
