“…All samples presented a mixture with open and closed cells ( Exhibit ) with diameters between 1 μm and 6 mm, similar to those reported by Gavin et al. (2018), due to the different sizes, a porous structure and an irregular distribution were observed (Soykeabkaew et al., 2015; Zaaba & Ismail, 2019a). This irregularity tends to get lost as the days go by, perceiving fewer and fewer pores in each sample, but at the same time preserving the shape of the cut in each one of them.…”

“…The extrusion conditions and the appropriate screw configuration were the critical factors affecting the reactivity of the protein and the properties of the mixtures. Walallavita et al (2016) and Gavin et al (2018) reports the methodology for obtaining a foam from PLA and the thermoplastic protein Novatein ® (NTP) which is a patented formulation of blood meal and chemical additives from extrusion with subcritical CO 2 expanded up to 11 times due to heterogeneous nucleation undertaken on grafting itaconic anhydride onto PLA using reactive extrusion with dicumyl peroxide as the initiator, obtaining a stable foam with different bubble sizes as multi-phase systems impact gas diffusivity.…”

Polymers with low environmental impact are of great interest worldwide to reduce greenhouse gases (CO 2 and CH 4 ) and soil and water contamination. Evaluating the biodegradation process of biopolymeric matrices obtained from different biodegradable biopolymers is a priority. This work evaluated the behavior of a foamed material based on biopolymers under the ISO 14855-2: 2007 standard under simulated natural environmental conditions and its ecotoxic potential of the material residues in the growth of seeds Phaseolus vulgaris. A percentage of biodegradation was obtained in the TPS/PLA samples: 84.7 ± 0.3%; 0% MG: 89.1 ± 0.4%; 2% MG: 82.4 ± 0.4%; 3% MG: 82.0 ± 0.%1; 6% MG: 81.0 ± 0.3%; TPSEG: 66.7 ± 2.4%, and TPSE: 62.9 ± 1.0%; having microcrystalline cellulose as a control sample. CH stretch bands were identified at 728 cm -1 related to PBAT vibration that remained constant in the samples containing PHA, evidencing that this material is not an alternative to elaborate foamed materials to improve their biodegradation. Protein-based samples increase their biodegradation rate, while based samples PHA remain resilient over time due to the blend of the polymer and the presence of PLA (1437.5 cm -1 ). The low or high decomposition of the material in weight loss corroborated this behavior of both blends. Regarding the ecotoxicity of the samples, there was no significant difference.

“…In the literature, there are studies that address the issue of packaging with biodegradable materials, some of the materials already used are hydrogels containing gelatin and pomegranate extract, cellulose or chitosan films, and protein films and foams. [7,[16][17][18][19] Another material that is already being studied as an alternative for the production of packaging is starch. In some cases, films are produced to package food, where starch is the base material and other components are added to achieve other required properties.…”

Short‐life packaging has been contributing to the increased consumption of polymers. Expanded polystyrene (EPS) is a material that is widely used in disposable packaging, however, its residue occupies a large volume, is difficult to degrade, and its recycling is expensive. That's why the interest in looking for a material of natural and biodegradable origin that can be an alternative to petrochemical‐based polymers. One possibility would be starch, which is a natural and biodegradable polysaccharide and can be extracted from different sources. However, natural starch does not have good properties for commercial application, requiring chemical modifications and/or the incorporation of additives. This article carried out a compilation of current studies that work on the development of packaging, whether film or foams, based on plasticized starch (TPS), and analyzes the influence of the incorporation of additives or treatments carried out in the starch. The blowing agent decreases foam density, cell size, and increases cell density. Incorporation of glycerol in starch foams increases the gelatinization temperature, decreases viscosity and resistance to expansion. The surfactant decreases the density and moisture absorption of the foam, the nucleating agent acted by increasing the mechanical strength and density of the foam, and decreases the absorption of water.
