Looking to send large bulky items? Here at Huntoffice you will find a wide selection of Gusset Envelopes. Gusset envelopes are designed to accommodate large oversized items to send through the post. Gusset envelopes usually come with either a block bottom or a V shaped bottom which allows the envelope to expand as needed to allow thicker documents such as books, files, catalogues and brochures to fit in comfortably. As gusset envelopes are designed to hold bulk or heavy items they are generally constructed with heavier paper than the usual envelope to help prevent tearing and damage to the contents during mailing. 

The gusset envelopes we provide are available in the colours brown or white and with or without a window. We also have a choice of different sized packs which include 25, 100 and 125, making them suitable for the home or small office right up to large businesses. Here at Huntoffice we have gusset envelopes from top brands such as New Guardian , Plus Fabric and 5 Star. 

Sizes of Gusset Envelopes

gusset envelopes sizes

Choose from a variety of sizes and formats, popular sizes include 

Seal types available on the gusset envelopes we supply: 


• Peel & seal – This is a very common way of sealing gusset envelopes. The flap of the envelope has a strip of glue which is protected with a strip of plastic. Remove the plastic strip from the flap and press against the envelope to seal. Peel & seal gusset envelopes are ideal if you like to buy in bulk because with the plastic strip protecting the glue, even after months of being kept in storage, the glue won’t dry out.

The style of gusset envelopes available in this section: 


Pocket – These pocket envelopes have the opening flap on the short edge of the envelope 


Window gusset envelopes – When the sheet is folded properly, window envelopes allow you to display the address that’s printed on the letter. These look the most professional which makes them a popular choice for businesses of all sizes. 


Plain gusset envelopes – These envelopes do not have a window and can be written on, printed on, stamped or used for franking. These envelopes are widely used in both the home and the office.
