“…The film color parameter index was determined using a color reader CR-20. Measurements were taken at five different areas per sample, and the resulting data were averaged to obtain values for lightness (L), redness (a), yellowness (b), and ∆E (color difference) using Equation (1). Films were kept at room temperature for 7 days (original) and 2 months for the stability aging test before measurement of the color parameter index.…”

Recently, there has been a growing concern among consumers regarding the safety of packaging products, particularly due to the presence of potentially harmful substances like synthetic pigments and inorganic dyes. These substances, which are often used to attract consumer attention, can migrate and contaminate products over extended shelf storage periods. To address this issue, the focus of this research was the development of a biodegradable packaging film using poly(butylene succinate) (PBS) incorporated with natural colorants extracted from roselle (RS) and sappan heartwood (SP). RS and SP serve as non-toxic and alternative pigments when compared to synthetic colorants. The biodegradable packaging films were prepared using blown film extrusion, encompassing different weight percentages of RS and SP (0.1%, 0.2%, and 0.3%). The films exhibited distinct colors, with RS films appearing pink to purple and SP films exhibiting an orange hue. The water vapor transmission rate slightly decreased with an increasing content of RS and SP extracts, indicating improved barrier properties. Additionally, the films showed reduced light transmittance, as evidenced by the UV–Vis light barrier results. The degree of crystallinity in the films was enhanced, as confirmed by X-ray diffraction and differential scanning calorimetry techniques. Regarding mechanical properties, the PBS/RS and PBS/SP films exhibited slight increases in tensile strength and elongation compared to neat PBS films. Moreover, the blended films demonstrated higher stability after undergoing an aging test, further highlighting their potential for use in biodegradable packaging applications. The key advantages of these films lie in their non-toxicity, biodegradability, and overall environmental friendliness.

“…The use of materials based on polysaccharides brings several benefits resulting from their properties. They are characterised by non-toxicity, biocompatibility, bioadhesiveness, and biodegradability [3,4]. However, despite the many advantages of using polysaccharides 2 of 22 alone, there is a growing demand for the development of materials based on natural polymers with functional properties, in particular as carriers of bioactive substances.…”

The dynamic development of the food industry and the growing interest of consumers in innovative solutions that increase the comfort and quality of life push the industry towards seeking pioneering solutions in the field of food packaging. Intelligent and active packaging, which affects the quality and durability of food products and allows one to determine their freshness, is still a modern concept. The aim of our study was to obtain two types of films based on chitosan and starch with micellar nanostructures containing extracts from turmeric rhizomes and hibiscus flowers. The presence of spherical nanostructures was confirmed using a scanning electron microscope. The structural and optical properties of the obtained composites were characterised by Fourier-transform infrared (FTIR), UltraViolet-Visible (UV-VIS), and photoluminescence (PL) spectroscopy. Scanning electron microscopy (SEM) analysis confirmed the presence of spherical micellar structures with a size of about 800 nm in the obtained biocomposites. The presence of nano-/microstructures containing extracts affected the mechanical properties of the composites: it weakened the strength of the films and improved their elongation at break (EAB). Films with nano-/microparticles were characterised by a higher water content compared to the control sample and lower solubility, and they showed stronger hydrophilic properties. Preliminary storage tests showed that the obtained biocomposites are sensitive to changes occurring during the storage of products such as cheese or fish. In addition, it was found that the film with the addition of turmeric extract inhibited the growth of microorganisms during storage. The results suggest that the obtained bionanocomposites can be used as active and/or intelligent materials.

In the 1960s, the Swedish company Celloplast patented the first one‐piece plastic bag for packaging, and such plastic bags are heavily used all around the world until they are banned by some countries for environmental and sustainability reasons. Similarly, the EU banned certain single‐use plastic items in 2021—but food packaging is not part of this new regulation. And indeed, the majority of food packaging encountered today in the supermarket is still made from traditional, petrol‐based plastics. This review summarizes recent efforts in developing more sustainable alternatives to such petrol‐based food packaging. Different natural sources and production processes used to develop biodegradable, biopolymer‐based materials (bbMs) are discussed, which are categorized into natural bbMs, modified/plasticized bbMs, and plastic bbMs. An overview of the material properties of commercially available bbMs and bbMs developed in academic research projects is provided, and are compared with the properties of conventional, petrol‐based materials used for packaging. Furthermore, the role of academic and industrial contributors along the value chain of bbMs is highlighted and challenges that are responsible for the still limited occurrence of bbMs in daily lives are discussed.
