What are Gusset Envelopes?

Gusset Envelopes are used by individuals, businesses, and organisations in the UK and Ireland to send documents or over-sized items that are too bulky to fit into a standard envelope.

These C4 size Gusset envelopes have an expandable side or base that allows them to hold larger, bulkier or thicker printed items such as Annual Reports, Catalogues, Brochures plus promotional materials.

They are also useful for posting items such as books, clothing, or small electronic devices.

Printed Gusset Envelope Specification

Gusset Envelope flaps are Peel & Seal to ensure the contents aren't tampered with.

The gusset depth expands to around 25mm, allowing gusset envelopes to securely hold a larger number of documents than a conventional C4 envelope.


Peel & Seal Flap on Gusset Envelope printed by TradePrintingUK


The glue is very strong, and because it has a protective strip it can be stored for a long time without the risk of drying out.

The flap is a very large Pocket-style (on the short edge).
