“…When the CNCs concentration increased to 3% CNCs, oxygen transmittance decreased to 87.1 g cm 3 /(m 2 •24 h). Therefore, this indicates that the resistance of the composite film to oxygen molecular penetration has increased by the nanometer size effect of Cellulose nanocrystals (Maes et al, 2021) TGA analysis of the film The supramolecular structure of cellulose materials impacts thermal degradation. The implications of cellulose's structural organization form on the PVA composite's thermal behaviour were examined.…”

“…The procedure differs depending on how the gas volume is calculated. A manometric approach involves first evacuating the lower pressure chamber and measuring the gas concentration by a rise in pressure (Maes et al, 2021).…”

“…It depends upon the solubility of gas in the polymer material and the diffusivity of gas through the material. ASTM D1434 provides two procedures that determine gas transmission rate (GTR), permeance, and permeability (only for homogeneous material) for polymer material (Turel, 2008;Maes et al, 2021).…”

Microbial cellulose has been gaining notable glare and publicity in various sectors, including the biodegradable packaging industry. The study emphasizes the development of microbial cellulose-based composite biodegradable, edible biopolymer to engender food and food product packaging. A characterization study of the mechanical property, barrier property, texture profile analysis, and biodegradability test was conducted for the combination, which appears strong enough to be employed as an application after solutions of film-forming polymers with 10 permutations were completed. Significant mechanical and thermal characteristics can potentially be seen in the composite film with the tensile strength of 56.6±3.13 mpa and TGA of maximum degradation of 92% occurred between temperatures 320°C- 360°C. The mechanical properties of biopolymers are improved by microbial cellulose, which acts as a nucleating agent throughout the gelatin (protein) and polyvinyl alcohol (plasticizer) matrix. The biodegradability test of the biopolymer with results of the highest biodegradability (70%) within five months was observed. These properties may be investigated in the context of the food packaging sector.
