Decomposition of biodegradable films developed on the basis of polyvinyl alcohol in the natural environment

The use of polymeric pack has made for many important problems. Biodegradable plastics may provide solutions to global environmental problems. The aim of this study is to examine the utilization possibilities in natural environment of biodegradable films, which was developed with polyvinyl alcohol and organic filler materials (amylum and cellulose). The films stability against the filamentous fungus was analyzed, the soil type with optimal conditions to the biodegradation of polymers was determined; the mold fungi were separated from biodegradable films and were identified to a genus.
