Рост экологической осознанности и ужесточение регуляторных требований (например, директив ООН по устойчивому развитию) стимулируют переход от традиционных пластиков к биоразлагаемым аналогам. В пищевой промышленности такие материалы особенно востребованы для производства упаковочных пленок, которые должны сочетать функциональность, безопасность и способность к деградации в природных условиях Cовременные тенденции в области разработки биоразлагаемой упаковки ориентированы на создание экологически безопасных материалов с высокой функциональностью и экономической эффективностью. Особый интерес представляют смеси поликапролактона (PCL) и крахмала, которые способны сочетать биоразлагаемость с необходимыми механическими и барьерными свойствами. В данной работе исследуется влияние состава крахмал-PCL-композитов на их механические характеристики, а также предложена математическая модель для прогнозирования прочности пленок на основе различных параметров состава. Экспериментальные исследования включали приготовление гранул и пленок с использованием экструзии и последующее определение прочностных характеристик. Применение математического моделирования позволило выявить оптимальные составы пленок, обеспечивающие требуемый баланс прочности, гибкости и биоразлагаемости. Полученные результаты подтверждают перспективность использования смесей PCL и крахмала в качестве альтернативы традиционным пластиковым упаковочным материалам, а разработанная модель может быть полезна для дальнейшего совершенствования технологий производства биоразлагаемых пленок. 

The rise in environmental awareness and the tightening of regulatory requirements (e.g., UN directives on sustainable development) are driving the transition from traditional plastics to biodegradable alternatives. In the food industry, such materials are particularly in demand for the production of packaging films that must combine functionality, safety, and the ability to degrade in natural conditions. Modern trends in the development of biodegradable packaging focus on creating environmentally safe materials with high functionality and economic efficiency. Of particular interest are blends of polycaprolactone (PCL) and starch, which can combine biodegradability with the necessary mechanical and barrier properties. This study examines the effect of the composition of starch-PCL composites on their mechanical properties and proposes a mathematical model for predicting film strength based on various compositional parameters. Experimental studies included the preparation of granules and films using extrusion and subsequent determination of strength characteristics. The application of mathematical modeling made it possible to identify optimal film compositions that ensure the required balance of strength, flexibility, and biodegradability. The results obtained confirm the feasibility of using PCL and starch blends as an alternative to traditional plastic packaging materials, while the developed model may be useful for further improving biodegradable film production technologies.
