MXSTEN® Plastomers are the lowest density Ziegler-Natta hexene based linear low density polyethylene (LLDPE) in the world. MXSTEN® Plastomers exhibit exceptionally balanced MD and TD properties along with superior low temperature dart impact strength properties. MXSTEN® Plastomers have excellent seal strength at low initiation temperatures which allows processors to run faster line speeds on their form, fill and seal machines. For such a low density polymer, MXSTEN® Plastomers have unique stiffness properties which makes it an ideal choice for stand-up and thermoformed pouches. MXSTEN® Plastomers meet FDA regulation 21 CFR 177.1520 and are a preferred resin for the flexible food packaging convertors. In addition to MXSTEN® Plastomers, Westlake's quality food packaging film resins include HIFOR®, HIFOR Clear® and HIFOR Xtreme® polyethylenes.
