Three Layers Co-extrusion Gemembrane Machine ( dam liner machine )


This machine is used to produce agricultrual film or geomembrane films ( dam liner ). The width can be 4 meter, 7 meters to 20 meters.

The production adopt advanced three layers co-extrusion technique, the output is large and production is easy to control.


Applications of geomembrane ( dam liner )Include:
Environmental ground water protection
Lining of dams
Ornamental lakes
Ponds and canals
Evaporation ponds
Water Storage
Reservoir liner
Heap Leach
Damp-proof membranes
Agricultural sheeting and covers
Where the requirement of the membrane is to withstand rough treatment, the emphasis being on mechanical resistance.


HDPE dam liner has the character of good stretching capacity, anti-penetraction ability, good physical and chemical ability, aging resistance, antioxidant etc.

It is a kind of material which is healthy, environment friendly, it is easy to transport and easy

To pave, with low cost but with high economic benefic. It can be widely used in dam, pond,

Aquiculture, irrigation, culvert anti-penetration, mining field, chemical industry, lakes, golf pond, express way, rail way, rubbish

Landfill site etc.



Our dam liner is produced with excellent Polyethylene (PE) resin with scientific prescription.

The main material is 97.5% high density Polyethylene resin and 2.5% carbon black, little

Antioxidant, heat stabilizer, aging resistant material and little ultraviolet radiation absorbing material.


It is produced with world advanced 3 layer extruding and blowing tech, without other addictives like plugging compound material and swelling agent.
