Expanding/gusset envelopes

Expanding envelopes – when you need more space

Do you want to send large number of letters in one envelope? Or perhaps you wish to send a thick company catalog or book? If so, standard letter envelopes or business envelopes may turn out to be insufficient. To make sure your documents are secured and have enough space, choose high-quality expanding envelopes. They have been designed with advanced use in mind.

Do you look for a perfect envelope?

An envelope with an expanding bottom may take various formats. Lyreco’s offer includes C4 expanding envelope, B4 expanding envelope and E4 expanding envelope. Thanks to increased density (most often 120-150 g/m2), every envelope with expanding sides gets more reinforced. In effect, it cannot be torn out or otherwise damaged due to impact of heavy documents, heavy catalog or hard diploma cover.

Do you value quality and good price?

No matter if you need C4 envelope with expanding sides or other format, we advise you to buy reliable-brand envelopes, such as Double Bag and NC Koperty, and our own brand – Lyreco. All of them are self-adhesive (with a seal), which facilitates packing.

If you are interested in special purpose envelopes, check protective envelopes, including bubble mailers and waterproof envelopes.
