Secure Mailing Seals

These 1.5 inch diameter white seals use permanent adhesive to keep brochures, flyers and newsletters securely folded during transit. The pack contains 240 labels across 40 sheets with six labels per sheet. They work with both laser and inkjet printers for easy customisation.

For Light Mailing Volumes

Suitable for offices, clubs or home users who regularly send folded documents and want a professional finish without envelopes. Not for senders who need tamper-evident security features or waterproof sealing for harsh shipping conditions. Buyers mailing heavy catalogues should verify the adhesive strength meets their weight requirements.

240 Labels Per Pack

The total quantity of 240 labels determines how many mailings you can seal before reordering. Each sheet provides six 1.5 inch round seals that peel quickly from the backing. Compatibility with standard laser and inkjet printers means you can print addresses or designs directly onto the labels using free templates from avery.com/print.

Questions about this item

How much heat or noise do the 1.5" 5278 seals produce when printed all day?

The seals are passive labels with no moving parts, so they generate no heat or noise during printing or handling.

What printer must I already own to use the 240 white round labels?

Any standard laser or inkjet printer works; the 40 sheets feed like normal paper.

Will the 5278 seals adhere reliably to older pre-printed brochures?

Yes, the permanent adhesive bonds to most paper stocks, including previously printed flyers and newsletters.
