Abstract

Se envasa un producto en un envase que puede volverse a cerrar por accion de la presion que comprende una película de capas multiples que tiene una capa interna termosellable que puede volverse a cerrar por accion de la presion. La capa interna contiene una poliolefina hiper-ramificada que presenta por lo menos 70 ramificaciones que consisten en cadenas laterales por 1000 átomos de carbono y una densidad de alrededor de 0,885 g/cm3, y/o un elastomero de etileno/alfa-olefina que tiene una densidad de hasta alrededor de 0,885 g/cm3. El envase se abre y se retira una porcion del producto, y se utiliza un sello inducido por accion de la presion para volver a cerrar el envase a una temperatura de por lo menos 11s C. El envase vuelto a cerrar se coloca entonces en un ambiente que tiene una temperatura de a -50sC a +10sC, de modo que se forma un sello vuelto a cerrar por accion de la presion, enfriado, con una fuerza de al menos el doble.
