Envelope Supply

To get the most out of your envelope supply and other marketing materials to send to your target audience, it is recommended that you discuss your requirements with one of our highly knowledgeable team members here at Romax. This is so we can gain an insight into the outer packaging required prior to finalising any marketing campaign you wish, so that you can deliver a truly outstanding promotional service to your clients. 


What are the different weights of envelopes?

Envelopes are measured in GSM – grams per square metre. The higher the grams, the heavier the envelope. A standard thickness of budget white envelopes is approximately 80gsm to 90gsm. For a quality envelope, you would expect the thickness to be approximately 120gsm with more than that being considered a luxury envelope.

What are the different types of envelopes?

There are various different types of envelopes. The gusset envelope is often used for mailing brochures and thick documents; pocket envelopes have the opening on the short edge of the envelope and the wallet envelope has the opening on the longer edge of the envelope. A banker envelope has a triangular flap, often found on greeting envelopes.
