| About |
|---|
| CV77519 is a polyethylene plastomer designed for blown film extrusion that contains no slip or antiblock,and high processing aid additives. Films produced with this resin exhibit exceptionally low seal initiation temperature with a broad hot tack window combined with good stiffness. Other features of this resin include extreme strength in cold and refrigerated temperature environments, high resistance to tears, and high MVTR. Application/Uses: Agricultural tubing Blown film Food packaging&& |
