Q-connect Gusset Envelopes
Designed to hold more paper than standard envelopes, gusset envelopes are a popular choice for those sending more than just a few sheets of paper. They are physically different from standard envelopes as they have expandable side panels that allow for the envelope to widen, giving you space for bulkier or thick documents, reports, brochures or catalogues. Gusset envelopes are a popular choice for sending papers because the contents will fit comfortably inside the expanded space, meaning you’re less likely to endure creases, tears or other damage during transit.
An office essential for many, we stock a board variety of gusset envelopes available in a variety of sizes, including the popular C4 and C5 formats. We also stock gusset envelopes in a range of finishes from peel and seal, gummed and self seal closures. Whether you want to stick to classic black, white or beige, or branch out and choose coloured envelopes, we have a wide range to browse through, from top brands like Blake and ValueX.
If you are struggling to find the envelopes you need, or are confused about what size you need, our knowledgeable team are here to help. Simply give us a call or send us an email, and we’ll get back to you as soon as possible.
