I. Introduction to HDPE Geomembranes
High-Density Polyethylene (HDPE) geomembranes have become the material of choice for containment applications across various industries. Among the different thickness options available, the 1mm HDPE liner stands out as the most versatile and cost-effective solution for many projects.
1. What is 1mm HDPE Geomembrane?
A 1mm HDPE geomembrane is an impermeable plastic sheet made from high-density polyethylene resin with a thickness of 1 millimeter (0.04 inches). This engineered material is specifically designed to provide superior fluid containment and environmental protection.
Key characteristics of Haoyang 1mm HDPE liners include:
l Density: 0.940-0.965 g/cm³

l Standard width: 1m to 10m
l Standard length: 50-200m per roll
2. Advantages Over Other Thickness Options
While HDPE liners come in various thicknesses from 0.15mm to 4.0mm, the 1mm version offers the perfect balance between performance and cost:
Thickness | Typical Applications | Advantages | Limitations |
0.5-0.75mm | Temporary covers, secondary containment | Low cost, easy installation | Limited puncture resistance |
1.0mm | Landfills, ponds, mining | Optimal cost-performance, good durability | Slightly higher cost than thinner options |
1.5-2.0mm | Heavy-duty applications, harsh environments | Superior strength | Higher material and installation costs |
