“…Functionalities of films are tailored by advanced technologies, such as nanomaterials in the form of nanofillers, such as nanotubes or nanowhiskers [26]. The industry manufacturing the polypackages has emerged to reinforce natural fibers, such as flax, hemp, banana, pineapple, sisal, kenaf, and coir, as fillers for better-composting properties [27][28][29]. Therefore, polymers can be produced from renewable sources or synthetic materials via the biosynthesis route [6].…”

Edible coatings, including green polymers are used frequently in the food industry to improve and preserve the quality of foods. Green polymers are defined as biodegradable polymers from biomass resources or synthetic routes and microbial origin that are formed by mono- or multilayer structures. They are used to improve the technological properties without compromising the food quality, even with the purpose of inhibiting lipid oxidation or reducing metmyoglobin formation in fresh meat, thereby contributing to the final sensory attributes of the food and meat products. Green polymers can also serve as nutrient-delivery carriers in meat and meat products. This review focuses on various types of bio-based biodegradable polymers and their preparation techniques and applications in meat preservation as a part of active and smart packaging. It also outlines the impact of biodegradable polymer films or coatings reinforced with fillers, either natural or synthesized, via the green route in enhancing the physicochemical, mechanical, antimicrobial, and antioxidant properties for extending shelf-life. The interaction of the package with meat contact surfaces and the advanced polymer composite sensors for meat toxicity detection are further considered and discussed. In addition, this review addresses the research gaps and challenges of the current packaging systems, including coatings where green polymers are used. Coatings from renewable resources are seen as an emerging technology that is worthy of further investigation toward sustainable packaging of food and meat products.

“…With the gradual shortage of petroleum resources caused by excessive development and the white pollution problem brought by the widespread use of plastic products, many researchers have begun to look for new materials that can replace traditional petroleumbased materials, as well as protect the environment (Feng et al 2020;Ramle et al 2020;Dixit et al 2021;Gao et al 2021;Rajeshkumar et al 2021;Khosravani and Reinicke 2022). The global plastic production continuously increased from 1.5 million tons in 1950 and is expected to reach 670 million tons by 2035 (Bajracharya et al 2016;Dixit and Yadav 2019).…”

“…Lignocellulosic materials such as rice straw, corn straw, sorghum straw, soybean straw, sisal, and hemp are usually used as a substitute in polymer matrix (Xu et al 2019;Feng et al 2020;Zhu et al 2020). Due to the poor compatibility and strong stiffness of lignocellulosic material, native biomass is not very compatible with polymer materials (Bartos et al 2021;Dixit et al 2021). Pretreatment (acid, alkali, oxidants, salts and solvent) of lignocellulosic material before the preparation of composite materials is necessary (Dixit et al 2021).…”

The objective of this research was to prepare an optimized bio-composite for packaging based on alkali-treated banana pseudo-stem fiber (BPSF), PBAT, and PLA using response surface methodology (RSM). The effects of three factors, i.e., alkali-treated BPSF (0.8 to 2.4 g), PBAT (0.75 to 2.25 g), and PLA (1.6 to 3.2 g) on two dependent variables, i.e., bending strength and tensile strength of bio-composite, were investigated. Box-Behnken design (BBD) provided the combination for an optimum composite, which was 1.15 g of alkali-treated BPSF, 2.09 g of PBAT, and 2.66 g of PLA, respectively. The bending strength and tensile strength for alkali-treated BPSF/PBAT/PLA composite were 32.62 MPa and 30.91 MPa, which was 20.50% and 16.51% higher than native BPSF/PBAT/PLA composite. The bio-composite prepared using the optimized results was further characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetry, scanning electron microscopy (SEM), mechanical testing, contact angles, and water absorption tests. Analyses showed that alkali-treatment could improve the adhesion and compatibility of BPSF in the polymer matrix. These outcomes were associated with the use of treated-BPSF for better mechanical strength and lower hygroscopicity. This result demonstrated that alkali-treated agricultural residue and degradable polymer could be used to prepare composite materials for green packaging application.

“…Dixit et al (2022) [ 99 ] produced novel alkali-treated hemp fiber/polyethylene/polypropylene composite films with optimal fraction for PE, PP and treated hemp fiber as 1.8, 1.118 and 1.2 g, respectively resulting in highest mechanical stability and lowest water vapor transmission rate. Previous studies found that addition of treated hemp fiber enhanced packaging properties such as contact angle, impact strength and transparency by 30%, 24% and 66%, respectively (with comparable mechanical and thermal stabilities to PE/PP composite film), while WVP decreased by 57% [ 99 ]. Mu et al (2012) [ 100 ] utilized hemp haulm (by-product of hemp fiber extraction) as cushioning packaging materials that showed better cushioning properties than expanded polyethylene, and similar to expanded polystyrene cushions with applied stress above 5–15 N/cm 2 .…”

Hemp (Cannabis sativa Linn.) is a high-yielding annual crop farmed for its stalk fiber and oil-producing seeds. This specialized crop is currently experiencing a revival in production. Hemp fiber contains pectin, hemicellulose and lignin with superior strength, while hemp seed oil contains unsaturated triglycerides with well-established nutritional and physiological properties. Therefore, focus on the utilization of hemp in various industries is increasing globally. This study reviewed recent applications of hemp components, including fiber and extract, in food, textile and packaging applications. Hemp fibers mainly consisting of cellulose derivatives have superior strength to be used as reinforcements in thermoplastic packaging and paper. Combined physical and chemical modifications of hemp fibers improved mechanical and barrier properties of composite materials. Physically and chemically processed hemp extracts have been used in food and non-food applications. Functional foods containing hemp oils deliver nutrients by their unsaturated lipids. High-quality hemp fiber with several fiber modifications has been applied in garments. Innovative applications of hemp components and by-products are increasing, thereby facilitating utilization of green sustainable biomaterials.
