Abstract
The paper presents the results of a study of three market samples of thermoplastic films based on various polymers (according to manufacturing enterprises): polylactic acid (PLA), thermoplastic starch (TPS) and polyvinyl alcohol (PVA). The initial samples were packaging bags with a thickness of 30±5 microns, labeled "compostable material". An IR spectrometric study of the samples was carried out, confirming the claimed composition. Destructive processes in polymer matrices before and after biotic (natural soil biocenosis) and abiotic influences (moisture, high and low air temperature, ultraviolet radiation) were assessed using strength indicators. It was found that none of the studied samples in natural soil conditions underwent complete biodegradation during the 6 months of exposure. It has also been found that materials labeled “compostable” react diff erently to external factors, which must be taken into account in their practical application. In particular, PLA-based films are stable in aqueous environments and insensitive to heat and UV radiation; PVA-based films, on the contrary, have too low moisture resistance but are more resistant to UV radiation and heat. Starch-based materials, despite their name, may be resistant to biotic and abiotic environmental factors. The results indicate the need to take into account the operating and disposal conditions when choosing “compostable” materials.
