“…The gelatin film with 0.5% durian leaf extract showed 17.6 times higher DPPH scavenging activity than without durian leaf extract (control) and improved the functional properties of the packaging film in slowing down oil oxidation. Verdi et al [72] also explored antimicrobial agents from Moringa oleifera extract (1%, 3%, 5%, and 10%) in the preparation of polybutylene adipate terephthalate (PBAT) films applied to strawberries. PBAT films added with Moringa oleifera extract could reduce fungal contamination, and the resulting films showed good thermal stability.…”

In recent years, much attention has been paid to the use of biopolymers as food packaging materials due to their important characteristics and properties. These include non-toxicity, ease of availability, biocompatibility, and biodegradability, indicating their potential as an alternative to conventional plastic packaging that has long been under environmental scrutiny. Given the current focus on sustainable development, it is imperative to develop studies on biopolymers as eco-friendly and sustainable food packaging materials. Therefore, the aim of this review is to explore trends and characteristics of biopolymer-based biodegradable films for food packaging, analyze the contribution of various journals and cooperation between countries, highlight the most influential authors and articles, and provide an overview of the social, environmental, and economic aspects of biodegradable films for food packaging. To achieve this goal, a bibliometric analysis and systematic review based on the PRISMA method were conducted. Relevant articles were carefully selected from the Scopus database. A bibliometric analysis was also conducted to discuss holistically, comprehensively, and objectively biodegradable films for food packaging. An increasing interest was found in this study, especially in the last 3 years with Brazil and China leading the number of papers on biodegradable films for food packaging, which were responsible for 20.4% and 12.5% of the published papers, respectively. The results of the keyword analysis based on the period revealed that the addition of bioactive compounds into packaging films is very promising because it can increase the quality and safety of packaged food. These results reveal that biodegradable films demonstrate a positive and promising trend as food packaging materials that are environmentally friendly and promote sustainability.

“…Sodium alginate (SA) is a water-soluble, anionic and non-toxic polysaccharide that possesses excellent film-forming properties. It is mainly isolated from marine brown algae and used in the food, pharmaceutical industry and coating applications (Verdi et al, 2021). Tong et al (2008) developed composite edible films by blending pullulan, alginate and carboxymethyl cellulose using solvent casting method.…”

Aim: To develop and characterize laboratory-made pullulan blended film using pullulan obtained from yeast-like fungus Aureobasidium pullulans mixed with gelatin and sodium alginate. Methodology: The laboratory-made pullulan blended (LPB) and standard pullulan blend (SPB) films were prepared by the solution casting method. Physical and mechanical properties were performed to examine the moisture content, film thickness, film solubility, tensile strength and elongation at break. Fourier transform infrared spectroscopy, X-ray diffraction, and field emission scanning electron microscope techniques were performed to analyze the interaction between the polymeric blends. Results: The polymeric blends had excellent miscibility and compatibility with the pullulan. The addition of glycerol to pullulan blended films improved the solubilization time in water at 125 sec. The blending ratio of pullulan, sodium alginate and gelatin led to lower rates of thickness, moisture content and higher elongation at break. Field Emission-SEM and FTIR analyses revealed that both sodium alginate and gelatin were compatible with pullulan. XRD results confirmed that pullulan blended films possess an amorphous structure that readily absorbs the moisture content. The biodegradability test confirmed the potential use of pullulan blended films as biodegradable plastic film. Interpretation: The laboratory-made pullulan blended films exhibited improved mechanical and water barrier properties due to strong interaction between the plasticizer and polymer matrixes which enhances the flexibility of pullulan blended films for the fabrication of biodegradable plastic film. Key words: Aureobasidium pullulans, Biodegradable plastic film, Microscopic techniques, Pullulan blended films

Starch is an environmentally friendly, renewable, green resource and an ideal alternative to polymers from petroleum resources. The preparation of high‐performance poly (butylene adipate‐co‐terephthalate) (PBAT)/corn starch composite materials is of significant importance for saving production costs and expanding the application fields of PBAT plastics. This study employed novel processing techniques such as melt blending and injection molding to fabricate PBAT/corn starch composite materials with polyurethane prepolymer (PCLPU) as a compatibilizer. The impact of varying polyurethane prepolymer concentrations on the composite material's structure, mechanical properties, morphology, thermal behavior, and water absorption was scrutinized. Mechanical performance testing showed that compared to the composite material without PCLPU (P90CS10), adding 5% PCLPU can increase the material's elongation at break from 350.2% to 359.0% and the tensile strength from 12.9 to 19.8 MPa. Scanning electron microscopy, thermogravimetric analysis, and water absorption results indicate that the composite material with the addition of the PCLPU compatibilizer has better compatibility, thermal stability, and water resistance than P90CS10. Additionally, the prepared composite material could be successfully blown into a thin film, further enriching the application of the composite material.Highlights A special interface structure was prepared to increase the compatibility of the poly (butylene adipate‐co‐terephthalate)/corn starch composite. Both the strength and the flexibility of the composite were successfully improved. The processing method through which modification was conducted in the melt was convenient, green, and effective. The prepared composite material has potential application value, and the processing method of the composite material is easy to transfer to industrial production.
