There are a few different types of tamper evident labels used for different things. We will talk about these uses in another blog post. Today we will look at four different types of labels:
- Non-transfer labels
- Total transfer labels
- Egg shell labels
- Tamper evident security tape
Non-Transfer Tamper Evident Labels
Non-transfer labels are self-adhesive labels that void themselves when removed. Non-transfer labels leave no markings on the surface that you remove them from. The clever thing about the non-transfer label is when you tamper with it the sticker gets destroyed so you cant reuse it but doesn’t ruin the thing it was stuck to. On the labels we tested we could not see any words like ‘void’ or ‘open’ on the unpeeled sticker so it is hard to tell if they are tamper evident labels until you remove them.

Total Transfer Tamper Evident Labels
Unlike the non-transfer labels, transfer labels leaves the bottom part of the label behind showing some kind of void message. The label is destroyed and cant be reused and the person who attached the label will know its been tampered with.
If you look carefully you can usually see ‘void’ or ‘open’ written on these labels before they are peeled off.

You can see the original sticker at the top, stuck back on, and the part left behind at the bottom.
Egg Shell Tamper Evident Labels
You have to be very careful with egg shell labels because they are fragile and tampering with egg shell labels will rip them into shreds.
Egg shell labels aren’t like other tamper evident labels as they are designed to resist being removed. Egg shell labels rip very very easily when you try to tear them off with your bare hands. Egg shell labels are one of my favourite labels because of their name and you get to destroy them 😀

Tamper Evident Security Tape
Tamper evident security tape looks like regular packaging tape but its not because when it is pulled off the tape voids itself leaving words on the box, like a total-transfer label, so cant be reused.
We have seen this tape on the internet but sorry we don’t have our own pictures of security tape as we haven’t got our hands on any yet to test 🙁
