The 500 micron plastic sheet — commonly known as 0.5 mm geomembrane liner — is one of the most widely specified thicknesses in the geosynthetics industry. With a nominal thickness of 0.5 mm (20 mil), this durable, impermeable sheet is manufactured primarily from High-Density Polyethylene (HDPE), Linear Low-Density Polyethylene (LLDPE), Polyvinyl Chloride (PVC), or Reinforced Polyethylene (RPE). It serves as a reliable barrier for containment, lining, and waterproofing in applications ranging from small backyard fish ponds and agricultural reservoirs to large-scale landfills, mining heap leach pads, wastewater lagoons, secondary containment for fuel/chemical tanks, canal liners, and stormwater detention basins.
In 2025–2026, the global geomembrane market (of which 500 micron / 0.5 mm liners represent a substantial volume) is valued at approximately USD 2.1–2.6 billion, growing at 5.8–7.1% CAGR through 2030–2032 (MarketsandMarkets, Grand View Research, Geosynthetics Magazine 2025–2026 aggregates). HDPE continues to dominate with 45–55% share due to its superior chemical resistance, long design life (50–100+ years in buried applications), and compliance with stringent standards such as GRI-GM13, ASTM D7465, and IS 15351:2015.
But the most frequent question from contractors, engineers, farmers, pond builders and procurement teams remains: how much does a 500 micron plastic sheet cost per square meter (or per square foot)?
Short answer (2025–2026 market data):
- HDPE smooth geomembrane (0.5 mm): $0.50 – $1.80 per m² ($0.05 – $0.17 per sq ft) in bulk
- HDPE textured geomembrane (0.5 mm): $0.75 – $2.50 per m² ($0.07 – $0.23 per sq ft)
- LLDPE geomembrane (0.5 mm): $0.60 – $2.20 per m² ($0.06 – $0.20 per sq ft)
- PVC geomembrane (0.5 mm): $0.45 – $1.60 per m² ($0.04 – $0.15 per sq ft)
- RPE / reinforced variants: $0.80 – $3.00 per m² ($0.07 – $0.28 per sq ft)
These are typical bulk ex-works or delivered prices (FOB factory or freight-included to most continental US/EU locations) for standard roll widths (4–8 m) and quantities >10,000 m². Retail/small-roll prices through online marketplaces or local distributors are often 40–120% higher.

1. Current 500 Micron Plastic Sheet Price Ranges (2025–2026)
Prices fluctuate based on resin costs (polyethylene feedstock), energy prices, freight rates, currency exchange, and regional supply-demand balance.
1.1 HDPE Geomembrane (Smooth & Textured) – Most Common 500 Micron Sheet
HDPE remains the benchmark material for 500 micron liners due to its excellent chemical resistance, UV stability (with carbon black), and long service life.
Average delivered price (US/EU mid-2026): $0.80–$1.80/m² smooth, $1.10–$2.50/m² textured (freight included to most locations).
1.2 LLDPE Geomembrane (0.5 mm)
LLDPE offers higher flexibility and elongation than HDPE, making it suitable for irregular subgrades and exposed applications.
- Bulk price range: $0.60 – $2.20/m²($0.06 – $0.20/sq ft)
- Advantages: Better low-temperature performance, easier installation on uneven surfaces
- Common uses: Decorative ponds, wastewater lagoons, temporary containment
1.3 PVC Geomembrane (0.5 mm)
PVC is flexible, easy to weld, and cost-competitive for short- to medium-term projects.
- Bulk price range: $0.45 – $1.60/m²($0.04 – $0.15/sq ft)
- Drawbacks: Plasticizer migration over time (reduced lifespan 10–25 years)
- Common uses: Small decorative ponds, canal liners, secondary containment
1.4 Reinforced Polyethylene (RPE) & Specialty Variants (0.5 mm)
RPE combines scrim reinforcement with polyethylene for high tear strength.
- Bulk price range: $0.80 – $3.00/m²($0.07 – $0.28/sq ft)
- Common uses: Floating baffles, large exposed liners, aquaculture raceways
