“…In previous studies, the most difficult point in the barrier coating process using NFCs was that the desired coating weight could not be sufficiently achieved to show high gas barrier property (Mousavi et al 2018;Lee et al 2020;Yook et al 2020). Thus, the concept of multi-layer barrier coating that forms two or more barrier coating layers on one side of the paper was developed.…”

“…Several studies have been conducted to improve the barrier properties of paper with NFC coatings. However, it was found to be difficult to increase the coating weight due to the low solid content of NFC (Lavoine et al 2014;Mousavi et al 2017;Lee et al 2020). Moreover, the hydrophilic NFC cannot reduce the water vapor transmission rate (WVTR) of the barrier-coated paper (Nair et al 2014).…”

A multi-layer barrier coating technology was developed using nano-fibrillated cellulose (NFC) alongside a hydrophobic, paraffin-free biowax for manufacturing an eco-friendly functional packaging paper. Anionic NFC was prepared by isolating hardwood-bleached kraft pulp (Hw-BKP) using a micro-grinder, and cationic NFC was prepared by the quaternization reaction of the anionic NFC. Thereafter, a three-layer barrier-coated paper was manufactured using cationic and anionic NFCs and biowax. The air permeability and water vapor transmission rate (WVTR) of the three-layer barrier-coated paper were measured, and its coverage and coating layer structure were observed by scanning electron microscopy (SEM). The air permeability of the three-layer barrier-coated paper was more than 15,000 s and those WVTR was 67.1 g/m2/day. Its coverage and surface were considerably uniform and smooth. Thick and effective barrier coating layers were formed as indicated by SEM images. Therefore, it was concluded that a multi-layer barrier-coated paper with considerably high barrier properties could be produced using cationic and anionic NFCs with high gas barrier properties and biowax with high moisture barrier properties. Further, the structure could be used as a functional packaging paper with high barrier properties.
