Linear Low Density Polyethylene/LLDPE GEOMEMBRANE

LLDPE geomembrane’s full name “linear low density polyethylene geomembrane”,is manufactured by Calendar manufacture process,with the 100%virgin resin material and carbon black,no additive.

Thickness range:0.75mm-3mm(30mil-120mil), and 0.75mm/30mil , 1mm/40mil, 1.5mm/60mil, 2mm/80mil thickness are popular.

Roll width:1m-6m, normally 5.8m 6m

Surface: smooth surface, textured surface

Advantages of LLDPE Geomembrane liner:Waterproof,impermeable,nontoxic,more flexible,chemically resistant,UV resistant,Puncture resistant,tear resistant,long life;the tear, puncture and UV resistance is lower than HDPE.


LLDPE Geomembrane Production Process

Our LLDPE geomembrane resin supplier are all world famous manufacturers,the lldpe liner use calendering process, the polyethylene resin is heated to the melting point in the extruder barrel,and molten plastic is extruded and then passed through pairs of rollers that extrude the molten plastic into a sheet film. The thickness of the liner depends on the gap between the pairs of rollers. The calendering process needs four or more pairs of rollers that gradually reduce the liner thickness, polish the surface, add a textured pattern. After the liner passes through the final rollers, it is cooled and to a winding roller where it is coiled and edge trimmed.

What is LLDPE plastic used for?

-fish shrimp ponds,landfill,mining,containment etc.

Is LLDPE UV resistant?

-Yes, carbon black can increas the uv resistance property.

What is the difference between HDPE and LLDPE?

-LLDPE is more flexible,HDPE is rigid.
