Boosting the drying shrinkage with fibrillated cellulose is one potential way to increase elongation and 3D formability of paper

Elongation is an important property of many packaging board and paper grades. Paper with high extensibility could provide an alternative for oil-based packaging materials. In this work paper strength and elongation properties of unrestrained dried paper was improved by adding micro- (CMF) and nanofibrillated cellulose (CNF) material to the paper via spray or wet-end addition.
