Abstract
Una película incluye 20,0 por ciento en peso a 69,5 por ciento en peso de un polímero basado en polietileno lineal de baja densidad (LLDPE). El LLDPE tiene una fracción de alta densidad (HDF) de 3,0% a 8,0%, una relación I₁₀/I₂ de 5,5 a 6,9, y una distribución de ramificación de cadena corta (SCBD) menor o igual a 8,0ºC. La película también incluye 0,0 por ciento en peso a 10,0 por ciento en peso de polímero a base de polietileno de baja densidad (LDPE), y 30,0 por ciento en peso a 70,0 por ciento en peso de formador de poros.
