How to Choose Poly Sheeting for Your Facility

Poly sheeting is flat polyethylene film on a roll, used for temporary walls, dust containment, equipment covers, and moisture barriers. This 7-step process covers thickness, reinforcement, fire rating, and size, with a fire-code check before any plant project starts.

Your maintenance crew hangs plastic to wall off a line during a renovation. Two days later the sheeting has a tear running floor to ceiling, and dust covers the packing area next door.

The right poly sheeting prevents those headaches.

Where Manufacturers Use Poly Sheeting

  • Temporary walls and enclosures during renovations or shutdowns
  • Dust and debris containment
  • Covers for idle equipment or stored inventory
  • Ground covers and moisture barriers

Thickness Options

Sheeting thickness comes in mil. One mil equals one thousandth of an inch.

Thickness

Best for

6 mil

Containment walls and covers, the most common choice

10 mil

High traffic, rough handling, long projects

8, 12, 20 mil (custom)

Special jobs

The 7-Step Selection Process

  1. Define the job. Wall, cover, ground cover, or moisture barrier.
  2. Pick the thickness. Use the table above.
  3. Decide on reinforcement. Reinforced sheeting has a scrim, a grid of polyethylene cord laminated between two film layers. The scrim stops a small puncture from turning into a long tear. Choose reinforced for any wall people walk past.
  4. Check the fire rating. Many facilities and fire codes require fire retardant (FR) sheeting indoors. Look for NFPA 701 Test Method 2, a standard fire test for how flame spreads across a material.
  5. Ask your safety team. Confirm your facility’s requirements with your safety manager or local fire marshal before you order.
  6. Choose extras. UV treated for outdoor use, anti-static FR for electronics areas, and clear, white, or black for light or privacy.
  7. Size the order. Common rolls run 100 feet long and up to 40 feet wide, with custom panels for large enclosures.

Common Mistakes

  • Buying clear, non-FR, unreinforced poly for an indoor shutdown to save a few dollars per roll.
  • Skipping the fire marshal check until inspection day.

Run the Numbers

Torn sheeting costs labor to re-hang. Dust in a clean area costs rework and cleanup. A failed fire inspection stops the project. Compare those costs with the upcharge for reinforced FR sheeting.
