Envelope types and sealing methods

Envelopes are still widely used to send and receive documents such as bank statements, letters, cards and much, much more. So we have put together a quick and simple overview of the main envelope types and sealing methods available:

Envelope types

envelope types

Banker

The banker envelope has a triangular flap along the longer edge. These envelopes are mainly used for general, lightweight correspondence but also commercial documents and direct mail.

However, a lot of the times this envelope style is also used for greeting cards or personal correspondence and letters.

Wallet

The wallet envelope normally has an almost rectangular shaped flap along the long edge. This type of envelopes is being used for lightweight correspondence and is suitable for automatic mailing machines.

Pocket

With pocket envelopes, the opening flap is positioned on the short edge which is what defines the envelope as a pocket. These envelopes are commonly used in all applications.

Booklet Mailer

This is a bigger envelope (usually C5 or C4 size) that opens on the long edge for easy insert of documents or booklets.
