Abstract: Azure laid ledger paper usually having yellowish colour is used for making of registered envelope. Registered envelope provides a protective medium for document, which is to be sent from one place to another. In India, the climatic conditions vary from one part to another part of the country. Also, the registered envelope should have sufficient mechanical strength in order to secure the document from damage and harsh atmospheric conditions during posting. It is necessary to develop such properties that may be helpful to protect the covered document against harsh atmospheric conditions and wear and tear during handling.In this paper, attempts have been made to impart such properties using indigenous raw materials like eucalyptus, bamboo and sawmill waste of pine. The results of laboratory made hand sheets are encouraging and match the specifications prescribed by ISP.
