Description
MDPE S403313 is a medium-density polyethylene with a broad molecular weight distribution and high melt strength. Produced using 1-hexene as a comonomer, it is specially designed for thin films requiring high tear resistance, good sealability, high strength, and high drawdown. It is suitable for manufacturing high-strength carrier bags and high-quality thin films for uni/multi-wall packaging.
