Ultra Low Density Polyethylene Resins

It is a polyethylene with a density approximately equal to 0.865 g/cm³ and offers greater strength, greater flexibility and better optical properties comapared to LLDPE. The main use of ULDPE is as a modifying resin, particularly for high polyethylene (HDPE) , low polyethylene ( LDPE) and polypropylene (PP). Adding ULDPE to polyethylenes and PP improves the impact resistance, flexibility and tear strength of these polymers. These resins are ideal for producing films for liquid packaging , because besides prevent leaks and spills, the packaging has a high resistance to tearing. The processing of cast films is made by blow or extrusion.
