Abstract:In the contribution, there will be presented few strategies that we have studied recently for producing of highly-performed rigid or flexible biopackaging materials, being fabricated as mono- or even multi-layers coating films from renewable biopolymers (soy-protein-isolate SPI, being a by-product of the soybean oil industry, and/or xylan as the most common hemicelluloses extracted from the woody biomass), nontoxic and non-volatile linear or branched additives (acting as plasticizer and/or cross-linking agents, Fig. 1), and nano-additives (e.g. microfibrillar cellulose, MFC giving the strength and improve barrier properties, Fig. 2) by using casting and/or compression molding technique. In addition, pre-oxidized xylan acting as a highly reactive and branched cross-linker (create hemiacetal or amide linkages, depends on the processing road used) was studied as a mixture with SPI (Fig. 3) and/or MFC.
