LDPE SC 7642 Polyethylene Resin is designed for high speed cast extrusion lines, where it provides excellent draw down, low neck-in and high melt stability with a good balance between stiffness and tear resistance. Due to its density, the coefficient of friction of films made with LDPE SC 7642 Polyethylene Resin will be lower. In association with DOWLEX* resins, it gives films with a superior balance between machine and cross direction properties. This resin can be readily extruded using conventional cast film techniques, using melt temperatures between 200 and 270 °C.

Complies with:
  • EU No 10/2011
  • U.S. FDA 21 CFR 177.1520(c )2.2
