Seal labels

Seals are designed to prevent various types of misuse and tampering. Modern seal labels prevent unauthorised external tampering with both new products intended for sale and those covered by a guarantee.

Any attempt to tamper with such a label is immediately visible, regardless of whether these are VOID-type labels or ones that are damaged through chipping or peeling.

Seal labels have the following applications:

  • Electronics – sealing of components at the production stage, seals for computers, mobile phones and other electronic equipment.
  • Cosmetics – securing packaging.
  • Cash registers – mandatory sealing of fiscal equipment.
  • Consumer electronics and white goods – service sealing of appliances.

VOID labels

This type of label cannot be affixed without damaging it. Any attempt to tamper with it ends up with the label being destroyed and, in addition, the words „VOID” or „VOID OPEN” appear where the label originally was, indicating that the seal has been broken. If the label was a warranty seal, the manufacturer’s warranty rights are therefore no longer valid.

These types of security labels are usually manufactured from polypropylene (PP), polyethylene (PE) and polyester (PET). They are available in silver, white, red, purple, blue, or with a mirror finish.

We can divide VOID labels into three main types, each of which leaves a different mark:

  • VOID standard – when the label is peeled off, the sticky text „VOID” remains;
  • VOID dry-removable – when the label is torn off, the dry „VOID” text remains, covered by a layer of laminate;
  • VOID cleanly removable –after peeling off the label, the „VOID” inscription appears, but it does not leave any traces on the surface to which the label was stuck (this type of seal can be used, for example, on lenses).

Damageable labels

It is not possible to remove this type of seal intact, so any attempt to tamper with it is immediately detectable. Crumbly and brittle labels, as their name implies, begin to crumble and break into smaller pieces when peeled off, which can no longer be glued back on. Delamination labels are designed in such a way that any attempt to peel them off ends in the label becoming unstuck and leaving an unsightly residue.
