“…In recent years, different forms of cellulose have been used in the development of composite films, including carboxymethyl cellulose (CMC) (Roy & Rhim, 2020), CNF (Ahmadi et al, 2021), MCC (Cheng et al, 2021c), cellulose nanocrystals (CNC) (Xiao et al, 2020), RC (Saedi et al, 2021a) and bacterial cellulose (BC) (Xie et al, 2020). The combination of inorganic NPs and plant extracts in cellulose matrices imparts unique antimicrobial and antioxidant activities to them, which expand the application of composite films and attract extensive research interest (Ebrahimi et al, 2019;Rashidi et al, 2021;Zhang et al, 2021c). The application of cellulose and its derivatives has been a growing trend in the food industry because of its unique characteristics, structure, and properties (De Oliveira et al, 2021;Hu et al, 2021).…”

Inorganic nanoparticles (NPs) and natural antioxidant compounds are an emerging trend in the food industry. Incorporating these substances in biobased and biodegradable matrices as polysaccharides (e.g., starch, cellulose, and chitosan) and proteins has highlighted the potential in active food packaging applications due to more significant antimicrobial, antioxidant, UV blocking, oxygen scavenging, water vapor permeability effects, and low environmental impact.

“…14 Current applications of CNFs in food packaging focus more on directly coating or wrapping the food surface or incorporating them into plastics. Zhang et al 19 designed a CNF/CMC/aloe juice (AJ) film and wrapped fresh pork with it. The addition of CNF and AJ lengthened the shelf life of pork, but simply wrapping raw pork in films cannot ensure airtight packaging.…”

Food packaging is critical since proper packaging can extend the shelf life of foods. Currently, petroleum-based plastics, such as poly(ethylene terephthalate) (PET), polyethylene (PE), and polypropylene (PP), are commonly used as packaging materials, but they have led to a lot of waste and environmental pollution. In this study, a previously reported method was modified to fabricate a cellulose nanofiber (CNF) and carboxymethyl cellulose (CMC) paste to make it more homogeneous and less laborconsuming, and it was utilized it as a coating material for molded pulp (MP) food trays. A smooth and uniform dry CNF/CMC coating with a thickness of ∼200 μm was achieved via over-molding. To improve adhesion, chitosan was coated on the MP between layers. Uniaxial tension, "crush strength" compression, and "cross-hatch" and lap-shear adhesion tests were performed to characterize the mechanical enhancement by the coating. Gurley air porosity and water vapor transmission rate tests were conducted to compare the barrier properties against air and moisture between the CNF/CMC-coated MP trays and the uncoated MP trays. Oil and grease resistance testing using the TAPPI-T559 standard showed that coated samples can resist grease much better than uncoated samples. Finally, the trays were lidded with two different kinds of plastic films: poly(lactic acid) (PLA) and poly(ethylene terephthalate) (PET). Raspberries, blueberries, and cherry tomatoes were then used for food storage testing, where it was found that the coating helps extend the shelf life of fruits.

“…Different biopolymers, such as alginate, chitosan, carboxymethyl cellulose, and hyaluronic acid have already been studied comprehensively in wound healing. ,− Alginate is an immensely explored biopolymer in the field of tissue engineering. − It is commonly used for wound dressing because of its biocompatibility, easy availability, and cost-effectiveness . Carboxymethyl cellulose (CMC), a semisynthetic biopolymer, has been used because of its moisture sorption properties and biocompatibility. − A wound dressing material should be able to absorb the exudate to prevent wound infection.…”

Wound healing using an alginate-based biopolymeric film is one of the most preferred treatments. However, these films lack mechanical strength (elasticity and tensile strength), show higher initial burst release, and exhibit high vapor permeability. The present study reports the development of nanosheets derived from titanium diboride (10 nm) (NTB)-incorporated biopolymeric films (0.025, 0.05, and 0.1% w/v) using sodium alginate (SA) and carboxymethyl cellulose (CMC) to overcome the shortfalls. The surface properties of the film, nanosheet distribution within the film, and possible interactions with the film are explored by using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), Fourier transform infrared (FTIR), and X-ray diffraction (XRD). These analyses confirm that nanosheets are uniformly distributed in the film and introduce unevenness on the film's surface. The tensile strength of the nanosheet-incorporated film (0.1% NTB film) using UTM is found to be 24.30 MPa (six times higher compared to the blank film), equivalent to human skin. The water vapor transmission rate of the film is also found to be in the desired range (i.e., 2000−2500 g/m 2 day). The biocompatibility of the NTB film is confirmed by the MTT assay test using NIH/3T3 cells and HEK 293 cells. Furthermore, the scratch assay shows that the developed films promote cell migration and proliferation. The antibacterial activity of the film is also demonstrated using a model drug, tetracycline hydrochloride (TCl). Besides, the film exhibits the sustained release of TCl and follows the Korsmeyer−Peppas model for drug release. Overall, the 0.1% w/v NTB film is easy to fabricate, biocompatible and shows superior mechanical properties.
