biodegradable films

The possibility of increasing the strength and operational properties of ecologically safe biodegradable polymeric materials based on hydroxypropyl methyl cellulose by using its modification with the different types of humic acids (HAs) from lignite is considered. Hybrid ecologically safe high-strength films with antibacterial properties were obtained for the first time. Physicochemical studies and IR spectroscopy confirmed the development of hybrid structures of hydroxypropyl methyl cellulose, modified with the different types of HAs.

Biodegradable films for bakery and confectionery products using differential scanning calorimetry are studied in this work. Expediency for the use of biodegradable films for marmalade, gingerbread, bakery products, and fondant confectionery according to organoleptic characteristics is established. The influence of the type of starch on film structure is studied with DSC analysis. DSC analysis was used to determine functionality of using glycerol as plasticizer, as this can reduce the temperature of melting point and glass transition of original compounds.
