For procurement managers, manufacturers, and engineers in packaging, agriculture, and construction sectors, determining the LDPE sheet 500 micron price is vital for cost-effective sourcing and project planning. Low-Density Polyethylene (LDPE) sheets at 500 microns (0.5 mm) provide exceptional flexibility, moisture resistance, and impact strength, making them indispensable for applications requiring lightweight yet durable barriers. As of October 2025, material pricing averages $0.25–$0.90 per square foot ($2.69–$9.69 per square meter), influenced by resin volatility and global supply chains, per ChemAnalyst and IndiaMart data. Full system costs, including fabrication and delivery, can range from $0.40–$1.50 per square foot. With the global geomembrane market valued at $52.7 billion in 2025 and projected to reach $70.94 billion by 2032 at a 5.9% CAGR (Market Research Future), this guide—backed by ASTM standards and 2025 market insights—empowers you to navigate pricing dynamics, optimize selections, and achieve 15–25% savings through informed decisions.

1. What Are LDPE Sheets at 500 Microns?

LDPE sheets at 500 microns are thermoplastic films produced from low-density polyethylene resin via blown or cast extrusion, forming flexible, translucent barriers with low crystallinity for superior conformability. These sheets, often rolled in widths of 1–6 meters and lengths up to 200 meters, weigh approximately 462.5 g/m² (density 0.925 g/cm³), enabling easy handling for large-scale deployments. Certified under ASTM D4801 for thicknesses ≥0.25 mm, they exhibit minimal environmental stress cracking and comply with FDA 21 CFR 177.1520 for food-contact safety, ensuring versatility across regulated industries.

Key Specifications and Parameters

Adhering to ASTM D882 for tensile properties and ASTM D4833 for puncture resistance, 500-micron LDPE sheets deliver balanced performance for demanding environments. Below are validated parameters from ISO 527 and ASTM D5199 testing:

  • Thickness: 500 microns (±5% tolerance), equating to 0.5 mm or 20 mils, optimized for barrier efficacy without brittleness.
  • Density: 0.918–0.935 g/cm³, promoting lightweight design (0.46 kg/m²) and recyclability under IS 2508-1984.
  • Tensile Strength: 12–20 MPa (machine direction), with 400–600% elongation at break, allowing 2–3x stretch before failure (ASTM D882).
  • Tear Resistance: 150–350 N/mm (Elmendorf), resisting propagation in dynamic applications like mulching.
  • Puncture Resistance: 400–700 N, suitable for foot traffic or light machinery (ASTM D4833).
  • Water Vapor Transmission Rate (WVTR): <2 g/m²/day at 38°C/90% RH, achieving 95% moisture retention (ASTM E96).
  • UV Resistance: 40–60% retention after 1,000 kJ/m² with stabilizers, supporting 3–7 years outdoor exposure (ASTM G154).
  • Chemical Resistance: Excellent to dilute acids/bases (pH 3–11); low permeability to oils (<0.5 g/m²/day).
  • Thermal Properties: Service range -50°C to +80°C; Vicat softening 85–95°C; melt index 0.25–2 g/10 min (ASTM D1238).
  • Roll Dimensions: Widths 1.5–6 m; lengths 50–200 m; customizable with additives like anti-block or slip agents.

Per a 2025 SGS certification report, these specs yield 92% containment efficiency in agricultural trials, outperforming thinner films by 25% in tear propagation resistance. The polyethylene films market, including LDPE, is forecasted at $253.52 billion by 2034 (Towards Packaging), underscoring their role in sustainable barriers.

Common Applications

The adaptability of 500-micron LDPE sheets, with 500% elongation and NSF-61 compliance for potable water, spans multiple sectors, enhancing efficiency and compliance:

  • Agriculture: Mulch films and greenhouse covers suppress weeds by 70% and retain soil moisture 30–40% longer (FAO 2025), ideal for row crops; liners for small reservoirs prevent 85% seepage.
  • Construction: Vapor barriers and temporary formwork sheeting reduce moisture ingress by 90%, extending concrete curing by 20% (ASTM D4397); used in foundation wraps for radon mitigation.
  • Packaging: Shrink films and pallet covers protect goods with 95% tear resistance during transit; food-grade variants for overwraps comply with EU 10/2011.
  • Environmental and Industrial: Secondary containment liners for spills, achieving EPA RCRA compliance; protective covers in mining reduce dust by 60%.
  • Consumer Goods: Squeeze bottles and liners, leveraging non-toxic properties for 50 million+ units annually in personal care.

In total, LDPE sheets at this thickness account for 15% of the $150.2 billion plastic films market in 2025 (Towards Packaging), driven by eco-friendly formulations reducing virgin resin use by 20%.
