Nanocellulose Based Kraft Paper for Packaging Applications
Kraft paper was reinforced with Nanocellulose produced from refining process using cotton linters.
Addition of nanocellulose, improved the mechanical properties of kraft paper such as tensile strength, bursting strength, fold endurance and tearing.
The tensile strength increased 3.5 times by addition of 20% nanocellulose in the kraft pulp. For the same concentration, the tearing strength, bursting strength and folding endurance increased by 1.56, 1.2 and 6 times respectively.
The increased mechanical strength of the Kraft paper enables the reusability and recyclability in Packaging application.
