There are many different sizes of envelopes, which can be used for any required applications, from promotional, personal or direct mail used for advertising and billing. The envelope shape and size as well as colour can have a influence on the attention it receives from end users and can make a considerable difference to response rate.
Envelope shapes are generally broken up into two categories . Wallet – opening on the long side and Pocket – opening on the short side. All envelopes have various options for sealing, based on the filling method required. Full gum (Lick & Sick) for automated inserting, Strip Seal ( Peal & Seal) and Self Seal for personalised inserting. Window and non window applications are available on most sizes.
