FIELD: chemistry.
SUBSTANCE: invention relates to organic high-molecular weight articles, particularly to a biodegradable film, and can be used as a production and/or packaging material. Biodegradable film contains potato starch, polyvinyl alcohol PVA 26-99, calcium carbonate with the following content of components, wt.%: potato starch 55–59.1, polyvinyl alcohol PVA 26-99 40–44, calcium carbonate 0.85–0.9. Invention also relates to shoe covers made from a biodegradable film, containing a mounted textile gum.
EFFECT: reduced noise when using the film, shorter time for decomposition of the film, high strength of the film, high shock-absorbing properties for protecting the packed object and almost complete reduction of moisture permeability.
