“…Results shown in Table 2 indicate that the smoothness of the coated paper was best when the dosage ratio of chitosan to acetic acid was 1:0.5. A relatively high pH value could reduce the degradation of chitosan (Liu and Chen 2011). With increasing dosage of acetic acid, fibers on the surface of the paper would undergo a quicker degradation process, which led to the destruction of the original fiber morphology of the uncoated paper, thus causing the film formation of chitosan to be worse and affecting the smoothness of the coated paper.…”

“…Chitosan is a naturally renewable resource, and it is second to cellulose in available quantity as a natural polysaccharide (Liu and Chen 2011). It is a biodegradable polymer, having the composition 2-amino-2-deoxidation-beta-D glucose connected through a β-(1-4) glycosidic bond, and its structure is very close to that of cellulose.…”

Biodegradable chitosan can be applied as a coating on the surface of kraft paper in order to improve its barrier properties against water vapor and air. The food packaging industry can benefit from the addition of chitosan to its current packaging, and in turn reduce pollution from plastic packaging plants. This paper discusses the film formation of chitosan, the permeability of paper coated with a chitosan layer, and the influence on the paper's surface and barrier properties under different process conditions. SEM (scanning electron microscope), AFM (atomic force microscope), ATR-FTIR (Fourier transmission infrared spectroscope with attenuated total reflection), and PDA (penetration dynamics analysis) were used to analyze the properties of chitosan's film formation and permeability. A controlled experiment showed that the chitosan layer was smoother than the surface of the uncoated kraft paper, had better film formation, and that there was no chitosan penetration through the kraft paper. The barrier properties against water vapor were strongest when there was a higher concentration of chitosan solution at the optimum pH, stirring speed, and those with a thicker coating on the kraft paper.

“…CTS coating on food packaging paper provides an oxygen barrier (Kjellgren et al 2006;Khwaldia et al 2010;Liu and Chen 2011), a moisture barrier (Reis et al 2011;Zhang et al 2014), an antibacterial barrier (Dutta et al 2009;Sun et al 2010), and shows other special packaging performances. It can also significantly increase the mechanical strength of the paper sheet (Laleg and Pikulik 1991).…”

Safe and environmentally friendly oil-resistant packaging paper is strongly desired in the food packaging industry. In the present work, chitosan (CTS) and chitosan/cationic starch (CTS/CS) coated papers were prepared and characterized. The results indicated that both the CTS and CTS/CS coated papers were highly oil resistant, and their oil resistance was increased with an increase in coating weight. The CTS/CS composite showed better thermal stability and water resistance than CTS. Paper coated with the CTS/CS composite containing 1:2 CTS to CS achieved an oil resistance level as required for food packaging. The mechanism of CTS/CS oil resistance, which has not been reported, was investigated by SEM, HPLC and particle size analyzer. The high oil resistance of the CTS/CS-coated paper was attributed to the formation of a film on the surface of the paper and the electrostatic binding between CTS and fatty acid to prevent oil from permeating and transferring.
