Abstract

Se trata de empaquetaduras espumadas que comprenden al menos un polímero de etileno homogéneamente ramificado y al menos un agene de soplado, donde elpolímero tiene una densidad de 0,85 a 0,93 g/cm3 y una distribución del peso molecular Mw/Mnd e 1,5 a 2,5 y un valor CBDI mayor de 50. Dichas empaquetadurasson particularmente útiles para cerrar envases para carnes y líquidos y no contribuyen a desmejorar el sabor /olor de los productos envasados. Asíresultan especialmente útiles enel e nvasado de alimentos. También se propone un método para obtener dichas empaquetaduras.
