Lotrene Q1018N is a linear low-density polyethylene (LLDPE) resin produced from ethylene and 1-butene (C4). Designed primarily for blown film extrusion, it is suitable for manufacturing flexible films used in industrial and consumer packaging.

With a typical density of 0.918 g/cm³ and a melt flow rate of 1.0 g/10 min, LLDPE Q1018N offers key parameters for evaluating its processing characteristics. When selecting this grade, manufacturers should also consider film strength, elongation, equipment conditions, and the performance requirements of the finished product.

Main Uses of Lotrene Q1018N

  • Industrial Packaging Films. LLDPE Q1018N can be considered for industrial liners, inner bags, heavy-duty packaging, and protective film products. Selection criteria include tensile strength, puncture resistance, tear performance, and the mechanical demands of storage and transportation.
  • FFS Films and Heavy-Duty Bags. Form-fill-seal (FFS) films and heavy-duty bags require suitable film strength, stable processing, and reliable sealing performance. Lotrene Q1018N may be evaluated for these applications, with final selection based on bag design, filling speed, load requirements, and sealing conditions.
  • Shrink Packaging Films. The grade may be evaluated for shrink-film formulations used to bundle products and protect goods during distribution. Processors should assess shrink behavior, film strength, optical quality, and packaging-line requirements before confirming suitability.
  • Agricultural Films. Q1018N may be considered for selected agricultural film formulations, including tunnel covers and mulch films. Outdoor applications require additional evaluation of UV resistance, weathering performance, film thickness, and service life. Suitable stabilizers may be necessary for prolonged exposure.
  • Garbage Bags and Flexible Packaging. This grade can be evaluated for refuse bags, packaging liners, and other flexible bag products. Manufacturers should match the resin formulation to the required load capacity, film gauge, sealing method, and end-use environment.

Processing Recommendations

(1) Temperature management: Begin within the recommended processing range and adjust according to melt behavior, extrusion pressure, and bubble stability. Excessive temperatures can accelerate thermal degradation.

(2) Bubble and gauge control: Optimize the blow-up ratio, cooling airflow, and haul-off speed to maintain stable bubble formation and uniform film thickness.

(3) Surface performance: Since Lotrene Q1018N does not contain slip or antiblocking agents, evaluate whether additional additives are needed to achieve the required film-opening behavior and coefficient of friction.

(4) Blending trials: Establish suitable blend ratios through testing. Changes in resin composition can affect extrusion stability, mechanical performance, and finished-film quality.

(5) Food-contact applications: Verify the applicable grade documentation, additive package, and regulatory compliance for the intended market. The resin designation alone does not establish that a finished film meets food-contact requirements.
