“…During the drying process, the internal winding of CS paste was released due to the surface tension. [ 37 ] However, the CN6 paste with lower viscosity can also penetrate the base paper successfully by capillary permeation. For more detail, there are plenty of whiskers crossed with each other in Figure 4e which can form the micro‐nano structure on the fiber surface to resist water.…”

Nano‐chitin whiskers (NWs) are a group of renewable materials that have attracted wide interest. As surface sizing agents, the relevant research has been mainly concentrated on barrier properties since they are considered to be potential plastic alternatives. Nevertheless, it is likewise important to explore their potential to improve print quality. Herein, different dosages of NWs are added into cassava starch (CS) to explore their influence on the surface sizing and printing process. With the addition of NWs, the rheological behavior and film‐forming ability of composite pastes are improved. CS‐6 wt% NWs film with a sizing weight of 2.5 g m−2 can fully cover the pores of the base paper. Compared with CS sized paper with a similar loading weight, contact angle and printing surface strength are increased by 60.0% and 78.6%, respectively. Besides, CS‐6 wt% NWs sized paper show less print mottle on the surface than CS sized paper.

“…Starches have long been used as binders to increase paper dry strength due to their ability to hydrogen bond to cellulose fibers (Li, Qi, Zhao, Chi, & Cheng, 2019; Rastogi & Samyn, 2015). They are also commonly used to bind mineral coatings, such as clays, which are used as glossy coatings for magazines where ink hold‐out is important.…”

“…Paper coated with blends of starches having positive and negative charges, which act as ionic cross‐links, have better oil and water resistance than paper coated with the individual starches (Chi et al., 2020). Starch nanocrystals, which are a type of physically cross‐linked starch, can decrease WVTR up to 40% when added to starch films (H. Li et al., 2019). A coating of starch nanoparticles at 1 to 6 g/m 2 was found to provide good grease resistance to paper (Kit values > 6) (Niemi, 2019).…”

“…Water resistance should improve if the acid were neutralized or removed but surprisingly, there have been few published attempts to do so. Successful efforts to improve water resistance of chitosan have included addition of fatty acids (Bordenave et al., 2010) and overcoating with beeswax (Zhang et al., 2014), polydimethylsiloxane (H. Li et al., 2019), and zein (Kansal et al., 2020).…”

Per‐ and polyfluoroalkyl substances and their alternatives in paper food packaging

Per‐ and polyfluoroalkyl substances (PFAS) have been used in food contact paper and paperboard for decades due to their unique ability to provide both moisture and oil/grease resistance. Once thought to be innocuous, it is now clear that long chain PFAS bioaccumulate and are linked to reproductive and developmental abnormalities, suppressed immune response, and tumor formation. Second‐generation PFAS have shorter biological half‐lives but concerns about health risks from chronic exposure underscore the need for safe substitutes. Waxes and polymer film laminates of polyethylene, poly(ethylene‐co‐vinyl alcohol), and polyethylene terephthalate are commonly used alternatives. However, such laminates are neither compostable nor recyclable. Lamination with biodegradable polymers, including polyesters, such as polylactic acid (PLA), polybutylene adipate terephthalate, polybutylene succinate, and polyhydroxyalkanoates, are of growing research and commercial interest. PLA films are perhaps the most viable alternative, but performance and compostability are suboptimal. Surface sizings and coatings of starches, chitosan, alginates, micro‐ and nanofibrilated cellulose, and gelatins provide adequate oil barrier properties but have poor moisture resistance without chemical modification. Plant proteins, including soy, wheat gluten, and corn zein, have been tested as paper coatings with soy being the most commercially important. Internal sizing agents, such as alkyl ketene dimers, alkenyl succinic anhydride, and rosin, improve moisture resistance but are poor oil/grease barriers. The difficulty in finding a viable replacement for PFAS chemicals that is cost‐effective, fully biodegradable, and environmentally sound underscores the need for more research to improve barrier properties and process economics in food packaging products.

“…Starch, the second most abundant biomaterial obtained from nature, is inexpensive and soluble in water and has many advantages. The binding property of starch can be advantageous in adhesives [37] [38] [39], paper coating applications [40], textile applications [41], etc. Starch consists of two polysaccharide parts of glucose with different shapes and structures, amylose and amylopectin.…”

The global energy crisis and overconsumption of non-renewable resources have depleted natural resources, climatic changes with global warming, and rise in sea level. The research on alternate sources and chemicals has resulted in the usage of green materials. These biomaterials are sustainable sources, biodegradable, and are abundant in nature. The replacement of petrochemicals with biopolymers has gained much importance in this aspect. Conventionally, polyvinyl alcohol is employed as a protective colloid in polyvinyl acetate adhesive. Polyvinyl alcohol has the limitation of petroleum origin, is replaced by biopolymers. Starch being a biopolymer, has gained interest in replacing polyvinyl alcohol as a stabilizer. Cellulose has a low cost, and the most abundant biomaterial finds application as a reinforcing agent in conventional adhesives. Exploring cellulose as a stabilizer for polyvinyl acetate emulsion polymerization with reinforcement has created potential applicability of cellulose in adhesives. Surface hydroxyl groups in cellulose act as sites for functionalization, making it material for the adhesive sector. This review paper aims to showcase biomaterials, namely starch, and cellulose, in the adhesive field. A detailed review of cellulose as functional filler for polyvinyl acetate emulsion adhesives has been explained.
