Традиционные пластиковые упаковки разлагаются сотни лет, вызывая накопление отходов в почве, воде и атмосфере. В данной работе исследуется процесс биоразложения пищевых пленок на основе поликапролактона (PCL) и модифицированного крахмала, а также их экотоксикологическое влияние. Экспериментально определены скорость разложения пленок в естественных условиях и в компосте, а также их устойчивость к воздействию микроорганизмов. Результаты показали, что биоразложение пленок напрямую зависит от содержания крахмала: чем выше его концентрация, тем быстрее пленка разлагается. В компостных условиях этот процесс идет значительно интенсивнее, чем в природной среде, что делает возможным их промышленную утилизацию. В то же время, высокая концентрация PCL замедляет биоразложение, но при этом повышает стабильность пленки. Экотоксикологические испытания подтвердили, что продукты разложения пленок не оказывают вредного влияния на почвенные микроорганизмы. Это делает их перспективным решением для создания экологически безопасной пищевой упаковки. Полученные результаты демонстрируют возможность широкого применения PCL-крахмальных композитов, а также необходимость дальнейших исследований по оптимизации их состава. Внедрение таких материалов в промышленное производство позволит снизить нагрузку на окружающую среду.</p></abstract><trans-abstract xml:lang="en"><p>The global issue of plastic pollution necessitates the development of sustainable biodegradable materials. Traditional plastic packaging takes hundreds of years to degrade, accumulating in soil, water bodies, and ecosystems. This study investigates the biodegradation process of food films based on polycaprolactone (PCL) and modified starch, as well as their environmental impact. The degradation rate of these films was analyzed under natural and composting conditions, along with their resistance to microbial exposure. The results demonstrated that biodegradation is directly influenced by starch content: higher concentrations led to faster degradation, making the films more adaptable to natural environmental cycles. In composting environments, decomposition occurred at a significantly accelerated rate compared to natural soil conditions, suggesting their potential for industrial composting. However, a higher PCL content slowed down biodegradation while increasing film stability. Ecotoxicological studies confirmed that the degradation products of these films did not negatively affect soil microbial activity, indicating their environmental safety. These findings highlight the potential of PCL-starch composites as eco-friendly packaging solutions. The study underscores the necessity for further optimization of biodegradable film formulations to enhance their performance in different environmental settings. Implementing these materials in commercial packaging could significantly reduce plastic waste and environmental pollution.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биоразлагаемые пленки</kwd><kwd>крахмал</kwd><kwd>поликапролактон (PCL)</kwd><kwd>механическая прочность</kwd><kwd>биоразложение</kwd><kwd>микробиологическая устойчивость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biodegradable films</kwd><kwd>starch</kwd><kwd>polycaprolactone (PCL)</kwd><kwd>mechanical strength</kwd><kwd>biodegradation</kwd><kwd>microbiological resistance</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Данное исследование было профинансировано Министерством науки и высшего образования Республики Казахстан BR22883587 «Совершенствование и разработка наукоемких технологий глубокой переработки сельскохозяйственного сырья для укрепления продовольственной безопасности РК».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rajendran R.C.
