The depletion of fossil fuels and environmental concerns have driven the development sustainable materials, including bio-based biodegradable plastics, as alternatives to conventional plastics. Although these plastics aid in waste management climate change mitigation, their vulnerability oxidative degradation impacts longevity, durability, performance. Natural antioxidants such tocopherols, flavonoids, tannins, extracted from plants or agri-food waste, present a alternative synthetic stabilizers by enhancing thermal stability polymers like poly(lactic acid) (PLA), poly(butylene succinate) (PBS), succinate-adipate) (PBSA), adipate-co-terephthalate) (PBAT), poly(hydroxyalkanoate) (PHA), starch-based materials. This review highlights recent advances stabilized with natural antioxidants, mechanisms action, role improving material properties for applications packaging. Additionally, it explores impact on recycling processes, advancements composite production techniques, future research directions. Bioplastics can achieve enhanced performance, reduce support circular economy incorporating antioxidants.

Food packaging plays an imperative role in the food processing sector by safeguarding foods from their point of harvesting until moment consumption. In recent years, biopolymers have attracted attention scientific community as alternative to conventional materials. Among available biopolymer sources, a lot focus has been on polysaccharides due superior barrier properties against gases, oils, and odors versatility. Moreover, there is also growing interest aliphatic polyester potential replacement for petrochemical-based synthetic plastics. Both polyesters gained popularity sustainable unique characteristics, including low cost, availability, biodegradability, gas moisture properties, film-forming capabilities, excellent heat resistance, ability be processed into films, trays, coatings. This review highlights structural features, advancements several vital polysaccharides, namely, starch, chitosan, cellulose, alginate, pectin, carrageenan, polyesters, polylactic acid (PLA) polyhydroxybutyrate (PHB) developing materials, applications industry. Conventional future perspectives biopolymer-based are comprehensively covered this review.

Poly(L-lactide)-b-poly(ethylene glycol)-b-poly(L-lactide) (PLLA-PEG-PLLA) shows promise for use in bioplastic applications due to its greater flexibility over PLLA. However, further research is needed improve PLLA-PEG-PLLA’s properties with appropriate fillers. This study employed zinc phenylphosphate (PPZn) as a multi-functional filler PLLA-PEG-PLLA. The effects of PPZn addition on PLLA-PEG-PLLA characteristics, such crystallization and thermal mechanical properties, were investigated. There was good phase compatibility between the improved evidenced by disappearance cold temperature, an increase crystallinity, decrease half-time. stability heat resistance enhanced PPZn. also PLLA-PEG-PLLA, demonstrated rise ultimate tensile stress Young’s modulus. We can conclude that has potential composite nucleating-enhancing, thermal-stabilizing, reinforcing ability.

In recent years, there has been a growing emphasis on packaging made from biodegradable materials. These materials not only help to reduce environmental impact, but also extend the shelf life of food products, thereby contributing significant reduction in waste. order develop novel polymeric films for use as active packaging, polylactide filled with vanillic acid were prepared. Analyses conducted determine influence structural morphology and key storage properties resulting films, including water vapor resistance, mechanical properties, UV barrier opacity, antioxidant activity. The effect firmness blueberries packed without additive was evaluated. research demonstrated that incorporating into significantly enhanced Furthermore, activity contributed extending freshness stored blueberries. addition did substantially affect transparency maintaining visibility fruit.

ABSTRACT This study investigated the antibacterial properties of polylactic acid (PLA)/chitosan: starch films incorporated with bitter orange essential oil (BOEO) for preserving rainbow trout fillets. Three BOEO concentrations (0.7%, 1.4%, and 2.1% w/w) were via casting. Increased concentration enhanced film hydrophobicity thermal resistance, but reduced tensile strength while increasing elongation. Atomic force microscopy revealed altered surface roughness. Antibacterial testing showed optimal activity against both Gram‐positive Gram‐negative bacteria at 1.2% BOEO. Films containing applied to fillets, significantly reducing spoilage (total bacterial count, psychrotrophic, lactic bacteria, Enterobacteriaceae), slowing chemical (pH TBA values), minimizing weight loss during 16 days refrigerated storage (4°C). These results demonstrate potential BOEO‐incorporated PLA/chitosan: extending shelf life trout.

The changes in consumer lifestyles have raised awareness of the variety food options and packaging technologies. Active smart represents an innovative technology that serves to enhance safety quality products. Smart packaging, as a subset this technology, entails integration additives into materials, thereby facilitating preservation or extension product shelf life. This technological approach stimulates heightened demand for safer products with prolonged predominantly relies on utilization natural active substances. Therefore, combination substances has significant impact characteristics particularly polymeric blend like Polylactic acid (PLA) matrix. So, review will summarize explains how addition agents influenced properties related performance through systematic analysis, providing new insights about relationship between types physical-mechanical properties, bacterial colony reduction, applications foods such meat, fish, fruit, vegetables. Through their integration, market systems is expected bright future.
