Lotrene Q3018C is a linear low-density polyethylene (LLDPE) resin developed primarily for cast film extrusion. It uses butene (C4) as a comonomer and is designed for film processing applications that require consistent extrusion performance, controlled film thickness, and reliable production efficiency.

Q3018C can be processed on suitable cast film extrusion lines and blended with low-density polyethylene (LDPE) or other compatible polyethylene resins to adjust the processing behavior and performance of finished films. Manufacturers can evaluate this grade for single-layer extrusion and multilayer coextrusion, depending on the intended film structure and production requirements.

Recommended Applications

(1) Cast Film Production

Cast film extrusion is the primary application for Lotrene Q3018C. Manufacturers can evaluate this grade for polyethylene film production where controlled thickness and consistent processing are important.

(2) Packaging and Stretch Film Formulations

Q3018C may be considered for packaging film and related stretch film formulations, subject to performance testing. Suitability depends on the required stretch behavior, puncture resistance, recovery, and film processing conditions.

Manufacturers should validate these properties through trials rather than assume that the resin will meet every stretch film specification.

(3) Single-Layer and Multilayer Coextruded Films

LLDPE Q3018C can be evaluated for single-layer extrusion or multilayer coextrusion with compatible polyethylene grades. Resin combinations can be designed around specific film requirements, including flexibility, sealing performance, and mechanical properties.

The final application should determine the resin blend, layer structure, and processing conditions.

For food-contact packaging or other regulated applications, buyers should verify the relevant compliance documentation for the intended use. The grade’s suitability should not be assumed without confirmation from the manufacturer.

Q3018C Compared with Other LLDPE Grades

The main differences between Lotrene Q3018C and other LLDPE grades relate to their intended processing methods, melt flow characteristics, additive packages, and end-use requirements.

  • Application focus: Q3018C is primarily intended for cast film extrusion, while other LLDPE grades may target blown film or different processing methods.
  • Processing characteristics: Its MFR of 2.8 g/10 min provides a reference for evaluating compatibility with specific extrusion equipment.
  • Additive formulation: The reported absence of added slip and antiblocking agents may affect the formulation decisions required for the finished film.
  • Blending flexibility: Manufacturers can evaluate compatible LDPE and PE grades to achieve the desired balance of processing and film properties.
