“…A considerable amount of research has focused on the properties of chitosan and NFC as individual additives for paper packaging. The use of chitosan has improved paper’s wet strength, water resistance, and mechanical properties, while NFC has proved to be useful in reducing the porosity of paper [ 10 , 11 , 15 , 36 , 37 , 38 , 39 ]. However, more research needs to be conducted on the synergistic effect of these additives, and their optimal concentration required for the enhanced wet strength of paper.…”

The demand for eco-friendly packaging materials has urged researchers to look for alternatives to petroleum-based polymers. In this regard, paper-based products have turned out to be a promising choice; however, their weak resistance to water has limited their application. The use of various additives to enhance paper’s moisture resistance is a common practice. However, considering the growing global agenda for sustainable development, the search for new bio-based paper additives has become increasingly important. This study investigated the potential synergistic impact of the addition of nanofibrillated cellulose (NFC) and chitosan additives (CHIT) to different fiber combinations to improve paper’s properties, in particular, their wet strength. The efficacy of the additive application order was examined and was found to be crucial in achieving the desired outcomes. The results showed that incorporating CHIT after NFC enhanced the paper’s tensile and burst indicators, as well as the paper stretch in the dry state, by 35–70%, 35–55%, and 20–35%, respectively. In addition, the tensile index and stretch in the wet state improved 9–13 times and 2.5–5.5 times over, respectively. The air permeability decreased 2.5–12 times over. These findings demonstrate that the sequential addition of the NFC and CHIT additives yield a greater enhancement of paper’s properties than using each additive separately.

“…Both cellulose and chitosan are not petroleum based, renewable and biodegradable but cellulose shows no film forming ability whereas chitosan shows good film forming ability. 43 Different researchers have done research on the application of cellulose and chitosan in papermaking, 37,44,45 composite preparation, 43,[46][47][48] drug delivery, 49 and so on. Chitosan (CH) is a biodegradable polymer with high potential to be used as strength additive in papermaking.…”

To enhance the ash in paper without reducing its strength property, ground calcium carbonate (GCC) filler was modified using polysaccharide prior to its addition at wet‐end of papermaking. Till now, modification of GCC filler using chitosan acetate (CH.A) is not explored. The novelty lies in showing the effect of CH.A as GCC filler modifier and its application in papermaking. The results showed that ash of paper get increased by around 18%, 53% and 63% after adding GCC modified using cationic starch (C.S) @ 20 kg/t of GCC, CH.A @ 5 kg/t of GCC and CH.A @ 10 kg/t of GCC respectively, in comparison to that attained by paper using unmodified GCC at the same dose at wet‐end of papermaking. The breaking length, burst factor and tear factor of paper having 11% ash (made using unmodified GCC) was found to be 2485 m, 21.73 and 47.63, respectively. The paper having 18% ash (made using GCC modified by CH.A 10 kg/t of GCC) showed breaking length, burst factor and tear factor as 2364 m, 22.24 and 46.72, respectively. This approach of using CH.A in papermaking will help the papermaker to improve profit and quality of paper.
