Extrusión soplada, Propiedades mecánicas, Polietileno, ANOVA, Aprendizaje automáticoResumen
El estudio evalúa el efecto que tiene la adición del compuesto biodegradable P–Life sobre las propiedades mecánicas de bolsas para hielo “IB”, fabricadas a partir de polietileno de baja densidad (LDPE). Se recolectaron datos de resistencia a la tracción, elongación, resistencia al rasgado, resistencia al punzonado e impacto durante un periodo de seis meses en una planta manufacturera. Se estudiaron correlaciones entre las propiedades mecánicas y las formulaciones con (B) y sin aditivo biodegradable (NB). El análisis de Pearson mostró correlaciones positivas entre el grosor de la película y sus propiedades (r ≥ 0.5). El ANOVA reveló diferencias significativas (p ≤ 0.05) entre ambas formulaciones en algunas propiedades. Además, se desarrolló un modelo predictivo mediante el algoritmo M5P con una precisión del 94,147%, validado con muestras reales. Los resultados sugieren que el uso de inteligencia artificial es viable para predecir propiedades mecánicas en procesos de extrusión de polímeros, lo que puede optimizar el control de calidad industrial.
