Propylene elastomer lowers PP heat-seal temperature

摘要

Mitsui Chemicals continues to make inroads with its metallocene-based Tafmer XM series of propylene-based elastomers in packaging applications.For instance,when used as blends with polypropylene (PP) for the heat-sealing layer of PP films-in particular OPP films-the new series will allow heat sealing at a temperature 20 deg C lower when compared to the existing propylene-based Tafmer XR grades to significantly raise the efficiency of the food packaging process.
