The development of environmentally sustainable plastics has gained prominence due to their eco-friendliness and renewable nature. In this research, eco-friendly plastic was formulated by blending Polylactic Acid (PLA) and Polycaprolactone (PCL) with the incorporation of chitosan as a filler. The primary objective of this study is to scrutinize and delineate the influence of varying compositions of PLA/PCL/chitosan on the mechanical attributes of eco-friendly plastics. This was achieved through hot pressing methods at a temperature of 200°C for a duration of 1 hour. The composition ratios for PLA/PCL were set at 2/8 g, 3/7 g, 5/5 g, 7/3 g, and 8/2 g, while chitosan compositions ranged from 0.2 g to 0.6 g. Comprehensive assessment of the eco-friendly plastics involved biodegradability tests, tensile strength measurements, elongation evaluations, functional group analyses, and examination of plastic film morphology. Optimal performance, ascertained through characterization, was achieved with a composition of PLA/PCL/Chitosan at 8/2/0.6 g, yielding a 38.8% degradation rate, a tensile strength of 42.53 MPa with a composition of PLA/PCL/Chitosan at 8/2/0.4 g, and an elongation of 6.96% with a composition of PLA/PCL/Chitosan at 8/2/0.2 g. The functional groups identified included N-H, C-H, C=O, and C-O groups, indicating a blending process without the formation of new functional groups. Morphology testing revealed a smooth surface, although some undissolved chitosan particles were evident, likely due to non-uniform blending.

“…PLA is a biopolymer derived from renewable resources, such as starch through lactic acid fermentation and chemical polymerization. It offers strength, transparency, and waterproof characteristics but is hindered by rigidity and low permeability Rihayat et al (2022), Rihayat et al (2021). To address these limitations, researchers have explored the incorporation of additional polymers like PBAT, Polyhydroxyalkanoates (PHAs), and Cellulose-Based Materials into PLA composites.…”

The extensive utilization of petrochemical polymer-based plastics has led to significant environmental challenges. A viable solution involves the incorporation of high-quality biomaterials as a substitute for traditional plastics. In pursuit of this goal, Polylactic Acid (PLA) and Polycaprolactone (PCL) biopolymers were combined with catechin and nano chitosan additives to innovate food packaging materials. The process involved the utilization of a screw extruder for mixing and melting. The sample formulation employed a combination of PLA polymer (9.5 g) and PCL (0.5 g). The variations in catechin (0%, 5%, 10%, 15%, 20%, 25%, and 30%), while nano chitosan was added in concentrations (5%, 10%, 15%, 20%, 25%, and 30%). The highest tensile strength recorded, at 45.10 MPa, was achieved by sample SA4, as indicated by tensile strength testing, FTIR analysis, and colony reduction. FT-IR analysis revealed the presence of functional groups, namely N-H, C-H, C=O, and C-O, signifying successful interactions between the PLA/PCL matrix blend and the additive components of nanochitosan and catechins. Remarkably, sample SA4 exhibited a remarkable 96% reduction in S. aureus bacterial colonies following 24 hours of storage.

“…Foods rich in water content can cause bioactive substances to migrate more quickly from the film matrix to the food surface. Additional factors such as film thickness and hydrophilicity may impact the rate at which bioactive substances migrate from the film matrix to the food surface [108][109][110][111].…”

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