Composition for retortable packaging applications

摘要

The present invention relates to a heterophasic polymer composition, comprising (i) a matrix comprising a propylene homo- and/or copolymer, (ii) an elastomeric ethylene/C3-C 12 alpha-olefin phase dispersed in the matrix; the heterophasic polymer composition further (iii) having an MFR(230°C, 2.16 kg) of less than 8 g/10 min, (iv) comprising monomer units derived from a compound having at least two double bonds; and (v) having a xylene cold soluble fraction (XCS) which has an amount of C3-C12 alpha-olefin derived monomer units of at least 60 wt%.
