This research study is based on finding environment friendly economical process for manufacturing of paper laminate composites. Rice straw an agro residue based fibrous raw material has been used for paper manufacturing. The paper industries are facing pressure for reducing the consumption of forest based wood raw materials in paper making. Rice straw can prove to be an important established fibrous raw material for paper industries. But higher percentage of ash and silica which is the main constituent of ash causes problems. The rice straw contains nearly 16 -20 % ash. Nearly 75 % portion of ash is silica. The paper sheets have been prepared using natural fibers of rice straw and fillers with different percentages. The paper sheets coated with paste of urea formaldehyde resins are combined together and treated at high pressure and temperature for composite formation. The different conditions have been explored for better properties and economical production. This study will provide a process for manufacturing of thin sheets of paper based laminated products which can be used in place of plastic bags. This will give environment friendly flexible paper based bags and wrappers along with hard sheets if higher number of sheets of paper is used.
