Background. The growth of the ecological problems, connected to the waste utilization led to the necessity of applying biodegradable polymers. The development based on acceptable technologies and formulizations of domestic equivalents of biodegradable polymers for using them in packaging food and pharmaceutical products. This is nowadays relevant all over the world. The aim of the research is to choose the most optimal compositions of the natural saccharides as a basement of the biodegradable
polymers.
Materials and methods. The polymers were studied by thermodynamic methods obtained on the basement of the composition of the natural saccharides which are carrageenan, hydroxypropylmethicellulose and gelose.
Results. The conducted research showed that all obtained solutions demonstrated thermodynamic resistance.
Conclusions. 33 compositions were obtained from the natural polymers. These compositions are for obtaining biodegradable membranes. By the values of thermodynamic characteristics, 13 were selected for further development of the technology of biodegradable packaging materials on their basis. 

Key words
