“…Comprehensive study of the composition properties showed that the application of cellulose fibers and PEG improved the compatibility between starch and PVA, the mechanical characteristics up to 52%, enhance the water vapor permeability. Debnath et al [ 130 ] used microcrystalline cellulose synthesized from elephant grass (growing in the North-Eastern states of India) to reinforce the starch-based materials obtained by solution-casting technique. The overall enhancement in rigidity, mechanical, and thermal properties was observed due to the good compatibility between molecules of microcrystalline cellulose and starch matrix.…”

The ecological problems emerging due to accumulation of non-biodegradable plastics are becoming more and more urgent. This problem can be solved by the development of biodegradable materials which will replace the non-biodegradable ones. Among numerous approaches in this field, there is one proposing the use of polysaccharide-based materials. These polymers are biodegradable, non-toxic, and obtained from renewable resources. This review opens discussion about the application of polysaccharides for the creation of biodegradable packaging materials. There are numerous investigations developing new formulations using cross-linking of polymers, mixing with inorganic (metals, metal oxides, clays) and organic (dyes, essential oils, extracts) compounds. The main emphasis in the present work is made on development of the polymer blends consisting of cellulose, starch, chitin, chitosan, pectin, alginate, carrageenan with some synthetic polymers, polymers of natural origin, and essential oils.

“…202,203 The use of renewable polymers as packaging materials is increasingly current, with starch gradually becoming the most relevant alternative for the development of packaging. [204][205][206][207][208][209][210][211][212][213] A major advantage is that starch-based films can be produced by thermal processing and casting, with casting being the most used method in the laboratory. 214 The main disadvantages of starch-based films are related to low mechanical strength, sensitivity and solubility in water and limited water vapor barrier properties.…”

The limited degradation of synthetic polymers used in food packaging when discarded in the environment is a major concern for society. Therefore, industry and academia have sought to develop biodegradable and eco-friendly materials for single-use in packaging. An interesting alternative for the food industry is biodegradable polymeric films, which is why different biopolymers have been used in the production of sustainable packaging. It is worth mentioning that the use of biodegradable polymers is one of the most successful innovations in the industry to address issues related to the environment. Among the available raw materials, starch extracted from different renewable sources is very promising for this purpose, due to its abundance, low-cost compared to other polymers and ability to produce non-toxic films. However, when used alone, pure starch has many limitations, which can be overcome by developing a mixture with other polymers (polymer blends), preferably from renewable and biodegradable sources, such as poly(lactic acid) (PLA). In this context, the absence of literature reviews evidencing the results of the application of films in foods led us to write this article, given the importance of polymer blends produced with different types of starch (cassava, corn, pea, potato, rice and wheat) and the PLA matrix. According to the results, it is clear that polymer blends based on PLA/Starch for food packaging are very promising, already being part of the industries solutions, aiming to minimize the large volume of plastic waste of petrochemical origin discarded in nature. Obviously, as with any technology, more research is needed to further improve the performance of the films, and while much research has made great strides, there are still limitations that prevent the commercialization of these materials.

“…Moreover, the carbon footprint associated with the production and disposal of these materials contributes significantly to greenhouse gas emissions, exacerbating climate change concerns (Shen et al, 2020). In response to these challenges, the development of biodegradable and edible packaging materials has gained considerable traction (de Sousa et al, 2023). Edible films, typically composed of polysaccharides, proteins, or lipids, offer a viable alternative to conventional plastics.…”

Pearl millet, known for its adaptability to challenging agro‐climatic conditions, emerges as a valuable candidate for biopolymer‐based packaging. The AHB 1200 cultivar, distinguished by its high starch content, provides a reliable source for biopolymer extraction. The conversion of pearl millet starch into nanoparticles by acid hydrolysis represents a cutting‐edge method to enhance biopolymeric materials. The inclusion of these nanoparticle concentrations (0.5%, 1%, 5%, and 10%) into the film results in improved mechanical characteristics, reduced water permeability, and increased biodegradability. Furthermore, the lowered water solubility and reduced water vapor transmission rate (WVTR) further underscore their positive contributions. This study comprehensively examines various film properties, encompassing WVTR from 7.23 ± 0.06 to 4.57 ± 0.08 g/m2/s, moisture content, solubility from 35.29 ± 0.51% to 30.09 ± 0.15%, burst strength from 1102.11 ± 0.99 g to 1535.71 ± 0.63 g, thermal stability, and biodegradability from 65.16% to 92.89%. The findings highlight the notable advancements achieved through the integration of starch nanoparticles.Practical applicationsPearl millet (AHB 1200) starch nanoparticle‐based edible films offer a versatile solution for specialized food packaging needs because of their compatibility with various food types, dairy products, fresh produce, and so on. These films act as a protective barrier and maintain product freshness during storage and transit. It also has enhanced mechanical strength and tear resistance and provides vacuum‐sealed packaging, ensuring an extended shelf life. Beyond their functional benefits, these edible films present an opportunity for branding and marketing differentiation. The films made with pearl millet have an earthy, natural appearance that fits with today's customer inclination for sustainable and environmentally friendly goods. This allows manufacturers to leverage the films as a means of conveying their commitment to environmentally friendly practices, enhancing their brand image and consumer loyalty. Furthermore, the biodegradability of these films is preferred over plastic waste. They offer a viable alternative to traditional plastic packaging, aligning with global initiatives to reduce the environmental impact of packaging materials.
