We have brought the Paper Envelopes that are mainly brown in color and used for versatile purposes. These are often used in the corporate sector for supplying the documents or invitations with the printed advertisements on the displaying surfaces. The accessories like CDs and business cards are also packed in these wrappers. The envelopes are the packing materials, used by the postman to deliver the letters or documents to the correct person. The material quality is hardened which makes it resistant to mild tear and damage due to excessive moisture. These are often sealed to make the message reach only to the referred person.
