Labels can be a quick and easy way to add a little bit of extra security to a variety of items, from high value goods to important documentation. A label can be used not only to securely seal packaging, folders, and envelopes but to also increase the security of items by acting as a visual deterrent against unauthorised tampering AND by providing visual evidence that an item has been opened or otherwise damaged in some way.
There are a range of security labels available, including a group known as “Tamper Evident Labels”; these labels provide some form of visual evidence that someone has attempted to tamper with an item.
At Label Planet, we supply two kinds of Tamper Evident Labels: TAMPER EVIDENT VINYL LABELS (TEV) and SILVER VOID LABELS (SVP).
Tamper Evident Vinyl LabelsOur TEV labels are “frangible labels” designed to provide evidence of tampering by disintegrating into tiny pieces when any attempt is made to remove one of these labels. They are made with a strong permanent adhesive and a very thin, very fragile (hence “frangible”) vinyl face material, which means that the label disintegrates when you try to remove it – the result being that only a tiny fragment of the label is removed with the rest of the label remaining behind, as an indication that the label (and therefore the item) has been tampered with in some way.
Please note: it IS possible to (eventually) remove the entire label but it is extremely difficult and time consuming to make sure that every part of the label has been removed.
Our TEV labels are available in 11 stocked label sizes (available in 25 sheet packs for same day despatch from stock) and a further 33 made to order label sizes (available in 500 sheet boxes with up to five working days for despatch).
These labels can be (carefully) handwritten or printed using a laser printer – although, due to the fragile nature of the vinyl, you do need to take care when handling these labels to avoid damaging the material. These labels should be printed using a standard print setting (rather than a specific “Labels” or “Heavy Paper” setting) and we strongly recommend requesting a sample of these labels to make sure they are suitable for your requirements.
While they can be used on a range of surface types, they are best suited to solid inflexible surfaces where there is a fixed and consistent surface for them to bond with successfully (compared to flexible surfaces such as plastic bags or wrapping).
Silver Void LabelsOur SVP labels are “void labels” designed to provide evidence of tampering by leaving behind a message (the word “VOID”) when they are removed from an item. Our void labels are made with a silver matt metallic polyester face material and a “partial transfer” VOID adhesive; this is a permanent adhesive that is designed to split when a label is removed from an item – leaving part of the adhesive on the back of the label and part on the previously labelled item.
This makes these labels extremely popular for use as security seals (on product packaging and important document folders or envelopes), warranty labels on high value goods (to indicate that an item has been tampered with in a way prohibited by the terms of a warranty agreement), and as security labels on high value goods (to prevent items being resold illegally under a different name or brand).
Our SVP labels are available in 9 stocked label sizes (available in 25 sheet packs for same day despatch from stock) and a further 35 made to order label sizes (available in 500 sheet boxes with up to five working days for despatch).
These labels can be handwritten or printed using a laser printer; as the silver polyester has a metallised backing, we recommend using a standard print setting and NOT a specific “Labels” or “Heavy Paper” setting (this is because the metallised backing causes the labels to reflect the heat generated by laser printers, which can generate too much heat if the more specialised print settings are used).
