Abstract

Una composición de resina a base de polietileno para moldeo por inyección, estirado y soplado puede incluir un copolímero de etileno y una o más α-olefinas C4-C8. La composición puede tener una densidad, de acuerdo con la norma ASTM D792, que varía entre 0,946 y 0,960 g/cm3 y un índice de fusión (I5), medido de acuerdo con la norma ASTM D 1238 a 190 °C bajo una carga de 5,0 kg, que varía entre 5,0 a 50 g/10 min. Un método de producción de un artículo puede incluir el moldeo por inyección de la composición para dar una preforma; y el soplado por estirado de la preforma para proporcionar el artículo.
