Warp's Poly-Cover Construction & Agriculture Film - 6mil - 10ft x 100ft - Black

Heavy-Duty Black Barrier Film for Long-Term Ground Cover Use, 10ft x 100ft

The heaviest jobs — long-term ground covers, high-traffic barriers, extended outdoor exposure — need more than a general-purpose film can reliably deliver. Warp's Poly-Cover Construction & Agriculture Film is seamless, full-weight polyethylene rated to ASTM D-4397 and built to NBS PS17-69 and Handbooks 130 and 133, and this 6mil black version is the heaviest gauge in the line, with a sun-resistant finish for maximum outdoor durability.

At 10ft x 100ft, this wider, shorter roll suits heavy-duty coverage over broader single-pass areas such as equipment or material storage.

Key Features & Benefits

• Heavy-Duty 6mil Gauge — delivers the most durability in Warp's Poly-Cover line for long-term use, high-traffic areas, and demanding vapor-barrier jobs.
• No-Seam Full-Weight Roll — runs as one continuous sheet, avoiding the failure points a seamed or patched film can develop.
• Sun-Resistant Black Finish — blocks light transmission and resists UV breakdown, suited to weed suppression, mulching, and outdoor ground covers.
• ASTM D-4397 Rated — carries ASTM D-4397 certification, in line with NBS PS17-69 and Handbooks 130 and 133 for polyethylene sheeting.
• Made in the USA — manufactured domestically at Warp Bros.' Illinois plants.

Who Should Use This Film

This heaviest gauge suits contractors, landscapers, and agricultural operators handling long-term ground covers, high-traffic barriers, or extended outdoor exposure where a lighter film would wear through — and where blocking light for weed suppression or mulching is also the goal.

Frequently Asked Questions

What makes the 6mil black gauge the heaviest-duty option in the line?

At 6mil, this is the heaviest-duty gauge in Warp's Poly-Cover lineup, delivering maximum durability for long-term use, high-traffic areas, and applications needing a strong vapor barrier. It's the choice when a general-purpose or mid-weight film wouldn't hold up.

Is this film independently rated for construction use?

Yes. It carries ASTM D-4397 certification, in line with NBS PS17-69 and Handbooks 130 and 133, the specifications used across professional construction and agricultural sheeting.

Why choose black film at this thickness instead of clear?

The black finish blocks virtually all light transmission, which makes it well suited to weed suppression, mulching, and outdoor ground covers where excluding light is the goal. Its UV resistance also extends service life compared with clear film left in continuous sun exposure.

How is this heavy-duty film typically used in greenhouse or growing environments?

Growers use this heavier-gauge black film as a ground cover, floor liner, or long-term vapor barrier where durability under repeated use matters most. Its ASTM-rated polyethylene construction is built for that kind of sustained demand.
