Self-seal Manilla envelopes

Our self-seal Manilla envelopes are the secure choice for mailing confidential business information. Made from light brown paper, there’s minimal risk of print show-through and as Manilla paper is naturally stronger than standard paper, these envelopes are less likely to tear in the post or disintegrate in the rain.

Available in a range of sizes, all with self-sealing flaps, you can speed up the process of sending letters, invoices or statements. Our Manilla envelopes are windowless to ensure information inside remains secure. We also offer the DL envelope with a window to save on labelling costs.
