Bio-films have been produced that attract attention with their functional behavior among conventional food packaging materials of bio-based polymer blends. The physical and morphological properties copolymeric biofilms extensively investigated. Biodegradable copolymer films were by in situ polymerization technique prepared as solution casting. strong water absorbency polyvinyl alcohol the antim...

Abstract Questions and potential misperceptions have arisen about the contribution of liquid detergent capsules to environmental microplastics issue. The film these detergents is highly water soluble, also in cold water, as it must fully dissolve during every type washing process. Water-soluble grades polyvinyl alcohol, most commonly used capsule material, are recognised be biodegradable. In cu...

Lately, environmentally benign packaging materials with biodegradability, flexibility, and high barrier properties are sought after as a substitute for conventional plastic due to increasing pollution microplastics in the environment. Although natural polymers can be sustainable alternatives petro-sourced, non-biodegradable plastics, they suffer from poor mechanical properties. In this study, m...

polylactic acid based biodegradable nanocomposites reinforced with acetylated nanocellulose were fabricated with solution casting procedure. the nanocomposites were prepared by adding 1, 3 and 5% nanofiber loadings. the microstructure, physical, mechanical and thermal properties of the prepared nanocomposites were investigated. scanning electronic microscope (sem) analysis of the composites con...

Journal: :Food Packaging and Shelf Life 2021

An increasing interest in food packaging materials without environmental impact and able to improve shelf life has emerged the last decade. The aim of this work was produce biodegradable films from agroforestry (pine stumps) fishery (chitosan) residues with active compounds. N-carboxybutylchitosan (CBC) were developed inclusion a reinforcing material (cellulose), plasticizers (silicone or glyce...
