Importance of the testing of Paper & Packaging materials can be gauged from the wide and varied applications of such materials, from food items, pharmaceuticals, medical devices, dangerous goods to any other consumable goods. The mechanical and strength properties of paper indicate the intrinsic chemistry, morphology, structure of the individual fibers, and the network structure of the paper. Knowledge of these properties gives an idea of those chemical changes that leads to the loss of permanence of paper with time. Proper monitoring and manipulation of strength properties of paper can be utilized for evaluating the effectiveness of treatments for ageing.
