When you are choosing between polyethylene (PE) and PVC (polyvinyl chloride) for reinforced liners, the right choice depends on your project’s specific needs. I listed some comparison in order to sell my products best:

Polyethylene vs. PVC: Reinforced Liners Comparison

FactorPolyethylene (HDPE/LLDPE/RPE)PVC (Reinforced PVC)
DurabilityVery high, especially HDPE and RPEGood, but less resistant to punctures and tearing
FlexibilityLLDPE and RPE are flexible; HDPE is more rigidExtremely flexible, ideal for complex shapes
Chemical ResistanceExcellent (especially HDPE)Good, but less resistant to aggressive solvents
UV ResistanceHigh, especially RPE and HDPEModerate — often needs UV stabilizers
Temperature RangeWithstands wide temp swings (esp. HDPE)Not ideal for very cold conditions (can get brittle)
InstallationMore difficult to seam in the field (HDPE); RPE is easierVery easy to weld and patch
WeightRPE is lightweight; HDPE is heavierTypically lightweight
Longevity20–40 years (HDPE); 15–25 years (RPE, LLDPE)10–20 years depending on UV and exposure
CostGenerally higher upfront (HDPE), moderate for RPELower initial cost
Environmental ImpactRecyclable; no plasticizersContains plasticizers that may leach over time
CertificationsNSF, GRI-GM13 (HDPE); safe for potable waterMay need special formulation for drinking water use

We can provide the samples of HDPE, RPE and PVC, if you need, send them to you for free.

When to Choose Polyethylene Liners (HDPE, LLDPE, RPE):

  • High chemical exposure (landfills, mining, wastewater)
  • Outdoor or long-term applications with UV exposure
  • Projects needing high tear and puncture resistance
  • Potable water or food-safe environments

They are best for: Landfills, containment ponds, canals, mining, water reservoirs

When to Choose Reinforced PVC Liners:

  • Short to medium-term use
  • Applications needing extreme flexibility (tight corners, irregular shapes)
  • Easier field installation and repairs
  • Lower upfront cost is a priority

It is best for: Decorative ponds, temporary covers, agricultural tanks, secondary containment

Let us make a summary as below:
