A New mLLDPE for Extrusion Coating Applications

摘要

Metallocene polyethylenes are well known for providing superior toughness, heat sealing, and clarity versus conventional polyethylenes. Their unique attributes have been employed for almost a decade in the manufacture of many different high-performance blown and cast films for numerous end-use applications. Lower density metallocene plastomers have also found use in specialty extrusion-coated and laminated structures where good puncture and tear resistance along with excellent hot tack and heat sealing performance are required. An extrusion coating study has shown that a similar set of attributes can be obtained using a new mLLDPE. For the best extrusion coaitng performance, the mLLDPE should be blended with small amounts of LDPE.
