Gusset Envelopes

When you are sending thick documents, several sheets of paper or bulkier items, gusset envelopes are the perfect choice. Our envelopes come in C4 and C5 sizes and as standard or padded envelope styles. Next day delivery is available on gusset envelopes.

Plain or with a window, in a variety of weights from 120gsm upwards and with specialist finishes, such as water and tear resistant for additional durability, there is an option to meet with the varying needs of our customers.
