En un aspecto, un método para preparar una capa de sello desprendible comprende (a) proporcionar una primera mezcla que comprende (i) de 5 a 98 por ciento en peso de un plastómero o un elastómero a base de propileno utilizable en reactores (reactor grade) que tiene una distribución de peso molecular de menos de 3.5 y una densidad de menos de 0.89 g/cc y (ii) de 2 a 95 por ciento en peso de un segundo polímero seleccionado del grupo que consiste en polietileno, polibutileno, y polímero de estireno y mezclas de los mismos; (b) proporcionar al menos un polietileno lineal de baja densidad; (c) mezclar la primera mezcla con el al menos un polietileno lineal de baja densidad para obtener una segunda mezcla; y (d) extruir la segunda mezcla para formar una capa de sello desprendible, en donde la capa de sello desprendible tiene una temperatura de inicio de termosellado de menos de 120 °C cuando se sella a una presión de barra de 40 psi en un tiempo de permanencia de 0.5 segundos.
