Abstract. In recent years, there has been tremendous growth of interest in the utilization of non-wood based material to support the insufficient raw materials availability for the pulp and paper industry. Therefore, this study was conducted to investigate the characteristics of 120 gsm linerboard and corrugated medium paper made from unbeaten durian rinds chemimechanical (CMP) pulp. The linerboard and corrugated medium paper were prepared and tested according to Malaysian Standards / International Organization for Standardization (MS ISO) and Technical Association of the Pulp and Paper Industry (TAPPI) standard methods. Based on the burst index (2.03 kPa.m 2 /g), RCT (1.97 N.m 2 /g) and CMT (129N), the linerboard and corrugated medium from CMP durian rind pulp have shown a good potential as an alternative raw material for papermaking and comparable with other types of wood and nonwood based papers as well as current commercial papers.

“…Cationic starch (CS) (Ghasemian et al 2012) and synthetic polymers based on polyacrylamides (PAM) (Laleg and Pikulik 1991;Lu et al 2002;Wang and Jing 2014) are the most commonly used strength additives in papermaking. Cationic starch and PAM also provide other benefits, such as better retention of fines and fillers, fast drainage, and reduction of wastewater pollution.…”

Extending the limits of paper recycling by increasing the number of recycling cycles results in decreased mechanical properties due to the irreversible hornification of cellulose fibers. This process alters the fiber structure and properties because of the repeated chemical and mechanical treatments that occur during wetting and drying. As a result, poor tensile strength is the main source of customer complaints to paper manufacturers. Cellulose nanofibers (CNF) from bleached eucalyptus and pine pulps were investigated as potential strength additives because of their proven contribution to interfiber bonding. These results were compared to the results obtained using different families of strength additives. The effects on the mechanical properties of recycled old corrugated containers were studied by measuring bursting, tensile, and short span compressive strength. Cellulose nanofibers and cationic polyacrylamide (cPAM) improved the mechanical strength properties when they were added at doses around 4 wt.%. A combination of CNF and cPAM was also tested. The effects of the combined additives were not as high as expected compared to the results achieved individually. The CNF from pine pulp resulted in the highest increase in bursting index when combined with cPAM, achieving an increase of over 93%. The combination of CNF from eucalyptus pulp and cPAM increased the bursting index over 60%.

“…However, continuous improvement in the quality of paper grades is essential to meet the consumer's demand for high-grade food packing paper. There is an increasing interest to develop the utilization of natural fibers and improve the strength by adding natural strength additives, such as cationic starch (Ghasemian et al 2012), hemicelluloses , sugarcane molasses , gelatin (Khakalo et al 2014), and chitosan (Chen et al 2013a). Although biodegradable polymers like starch, sugarcane molasses, and gelatin are good raw-materials for preparation of packaging materials, their applications are constrained due to their hydrophilic nature and limited mechanical properties (Tankhiwale and Bajpai 2012).…”

In recent years, concerns about environmental waste caused by petroleum-derived chemicals as well as the consumer's demand for high quality food products, have prompted people to pay more attention to developing biodegradable food packaging materials using natural resources such as cellulose fibers and chitin derivatives. In this study, chitin whiskers have been successfully generated by hydrolyzing the α-chitin sample. Then the synthesized nano-sized chitin whiskers were used at ratios from 0.1% to 2% (wt%) for improving strength properties of paper sheets by the dip-coating method. Transmission electron microscopy (TEM) and field emission scanning electron microscopy (FE-SEM) were used to investigate the morphology of chitin whiskers and cellulose fiber compounds. The results showed that coating with chitin whiskers brought about an increase in tear strength, burst strength, and wet and dry tensile strength, with a decrease in Zeta-potential value.
