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.
