Most tabs (or clip seals as they are also referred to) are a round, clear plastic adhesive with a perforation across the centre. Normally when a tab is applied, the perforation is placed such that the recipient can open it along the perforation as in the example below.
- Single, perforated tab holds two flaps of the mailing piece together.
Tabs are usually used to seal an open edge of an item. This may be a requirement for mailing or simply a preference.
Sometimes tabs can also be use to join items, as discussed on our Avoid Stacking and Save page.
