Mechanical Performances

We investigated the efficacy of several nanoclays (halloysite, sepiolite and laponite) as nanofillers for Mater-Bi, which is a commercial bioplastic extensively used within food packaging applications. The preparation of Mater-Bi/nanoclay nanocomposite films was easily achieved by means of the solvent casting method from dichloroethane. The prepared bio-nanocomposites were characterized by dynamic mechanical analysis (DMA) in order to explore the effect of the addition of the nanoclays on the mechanical behavior of the Mater-Bi-based films. Tensile tests found that filling Mater-Bi with halloysite induced the most significant improvement of the mechanical performances under traction force, while DMA measurements under the oscillatory regime showed that the polymer glass transition was not affected by the addition of the nanoclay. The tensile properties of the Mater-Bi/halloysite nanotube (HNT) films were competitive compared to those of traditional petroleum plastics in terms of the elastic modulus and stress at the breaking point. Both the mechanical response to the temperature and the tensile properties make the bio-nanocomposites appropriate for food packaging and smart coating purposes. Here, we report a preliminary study of the development of sustainable hybrid materials that could be employed in numerous industrial and technological applications within materials science and pharmaceutics.

The increase in agricultural production and food quality has forced the growing use of plastics in various activities. The plastic wastes are partially recycled in or outside Portugal; nevertheless, the contaminated wastes are sent to landfill. It is crucial to consider new models for their valorization at a regional level and from a circular economy perspective. In the scope of the Placarvões project, a study was elaborated, which included the types and quantities of plastics used in the irrigation area of the Alqueva Dam, in southern Portugal. The crops that use the most plastic are intensive olive groves, almonds, and table grapes, which represent more than 91% of total plastic waste. The production of activated carbons (ACs) is a solution to avoid plastics landfill. ACs were produced from plastic used on food packaging (PB-Samples) and sheeting film (PS-Samples) by activation with K2CO3. ACs presented well-developed textural properties (PB-K2CO3-1:1–700 and PS-K2CO3-1:1–700 exhibited a volume of 0.32 and 0.25 cm3 g−1 and an apparent surface area of 723 and 623 m2 g−1, respectively). Both ACs performed very well concerning four pesticide removals from the liquid phase. This solution is very promising, such these ACs could be applied in effluent treatments on a large scale.

The use of plastic materials as food packaging materials has caused environmental problems, namely the accumulation of plastic waste. The presence of innovation in making food packaging with organic materials in the form of edible films can minimize plastic waste because organic materials can be degraded by decomposing microbes in a relatively short time. This review examines the production and characteristics of composite edible films based on polysaccharides and proteins. Several characteristics of the material that this film must meet, such as resistance to water and evaporation, are the standards that must be met for edible films. Starch-based materials are still too brittle to be the base material for making films because the hydrophilic nature of starch makes it easy to dissolve in water. The functional properties of starch need to be improved, including mixing it with other ingredients such as proteins, plasticizers, and essential oils in formulations. The mixing of these ingredients can form a formulation that forms an edible film with characteristics suitable for various food products.

The possibility of using plastic waste to manufacture hybrid bio-composite materials with the dry husk of Asian rice (Oryza sativa L.) is investigated. The most polluted and unsustainable plastic waste is High-Density Polyethylene (HDPE) due to its single-use, which decreases in quality if it is reused is selected. The mixtures chosen are local natural fiber and easy to find, potentially a preliminary study of a composites building material. Furthermore, to improve the tensile properties of this hybrid bio-composite material, an additional organic filler is used, such as rice husk (Oryza sativa L.) in a combination of 10%, 12%, and 15%. Samples for this study were processed using the hot press methods based on ASTM D882. Tested for tensile strength, modulus young, yield stress, and elongation is carried out to see an increase in the performance of the biocomposite material. The test results show that the best tensile properties are samples with 12% rice husk, resulting in excellent sample compatibility proofed by Scan Electron Microscopy to study bio-morphological composites. This project has shown that the composites based on natural fiber will be potential building materials due to their improved tensile properties.

The paper deals with the determination of the oxygen permeability and mechanical properties of butter and curd aluminium paper foils Radaflex applied in the food packaging. Foil Radaflex is a paper foil covered by the aluminium layer. The measurement of the oxygen permeability was realized according to the Standard STN EN 77 0333. The measurement of mechanical properties was realized according to the Standard STN EN ISO 1924-2. Determination of moduli of elasticity in the longitudinal and transversal direction were provided and tensile properties as maximal elongations, maximal tensile forces, tensile strengths, tensile indexes and strain at breaks of the longitudinal and transversal specimens were evaluated. The permeability of pure oxygen through aluminium paper foils was studied. Aluminium paper foil was not permeable for the oxygen.

The present study described reduces of plastic based non-biodegradable food packaging material and sustainability toward the environmental protection. The polyvinyl alcohol (PVA) based ternary blend biodegradable films with bio-materials (corn starch and pectin) in ratio 1:5, 1:2, 1:1 and 2:1 were synthesized by solution casting method in water as a solvent to improve the tensile strength, high % elongation at break, and sustained packaging properties. Citric acid and glycerol were used for cross-linking and plasticizing purposes which are also bio-degradable and non-toxic. Blend films were characterized by FTIR and checked out the cross-linking of different components. The dispersion of contents in films was analyzed by SEM images. Thermal stability and degradation behavior of casted films were studied with thermogravimetry and thermal stability increased in blends as compared to neat PVA film. Biodegradability of cast films was also checked by Soil Burial method and bio-degradation increased with time i.e. almost 50% degrades in 30 days and 68% after 90 days. Tensile properties of blend films were tested and found that tensile strength (18.85 MPa) and elongation at break (516%) are high in blend films as compared with neat PVA film (12.04 MPa, 170%). The films are eco-friendly and biodegradable, might be a replacement of plastic material in food packaging having improved tensile properties.
