Piggyback labels are made from combining two layers of adhesive substrate. The bottom layer forms the backing for the top. The label can be applied to any object as normal, the top layer can be a removable label that can be applied elsewhere, which may change the message or marking on the remaining label underneath. Often used on Express mail envelopes.

Asset Labels / Tags are used for marking fixed and non-fixed assets. They are usually tamper-evident, permanent or frangible and usually contain a barcode for electronic identification using readers. We normally see asset labels in shops and stores.

Blockout labels are not see-through at all, concealing what lies underneath with a strong adhesive.

Holographic stickers are used for authentication and protection against counterfeit. They can be used on ID cards, credit cards, products such as CD/DVD's, etc.
