Expanding & Gusset Envelopes

Send files, documents and papers with ease!

Keep your documents in perfect condition and increase the number of files and documents you can send at one time with our gusset envelopes and expanding envelopes! Made from robust cardboard, these envelopes are great for sending more files and papers than standard envelopes.

Despite being robust and resilient, these envelopes are sustainable, making use of a material suitable in companies where being able to recycle products is a priority. Whether the envelope includes a gusset or not, all can be recycled.

Our range of gusset envelopes are available in several sizes, making them great office all-rounders. Envelopes with clear windows make postage quicker, removing the need to add addresses if postal information is included on the document being sent. A peel and seal feature again helps to speed up your postage processes, great for busy post rooms! Self seal envelopes are secure, convenient and remove the need for tape or manual sealing.

Envelopes featuring a gusset are especially robust, making them ideal for sending items such as certificates, images, contracts and blueprints. The gusseted construction will help prevent bending, tearing and crinkling.

Expandable envelopes are another great option for sending bulkier items or larger numbers of files and paper. Again available in several size varieties, our expandable envelope range is suitable for a wide selection of office uses. Our expanding envelopes do not all feature a gusset, however a thick manila material makes them suitable for general use and offers a good degree of protection and support.
