The BERRY GLOBAL 625926 is a 4-mil black polyethylene sheeting roll measuring 12 feet wide by 50 feet long, supplied single-wound with no folds. Designed for use as a vapor barrier, dust barrier, and general-purpose cover, this sheeting is manufactured to meet ASTM D4397-91 specifications. The 4-mil thickness delivers a balance of flexibility and tear resistance suited to demanding job-site conditions. At 12.5 pounds per roll, it is manageable for one- or two-person placement. Licensed contractors and trade professionals across multiple disciplines rely on this product for moisture control, containment, and surface protection.
This polyethylene sheeting is used in residential and commercial construction, crawl space vapor barrier installation, concrete curing, landscaping fabric replacement, and temporary dust containment during renovation work. Its pliable, single-wound format allows quick unrolling across large areas without bunching or creasing. The black pigmentation blocks light and is suitable for applications where opacity is required, such as ground cover vapor barriers and staging area protection.
Designed as a general-purpose polyethylene sheeting roll suitable for use in construction, HVAC rough-in, plumbing, crawl space encapsulation, and site preparation applications where a 4-mil vapor barrier or protective cover is required.
Installation is typically performed by general contractors, HVAC technicians, plumbers, or crawl space specialists depending on the application. When used as a crawl space vapor barrier, secure edges against foundation walls with tape or mechanical fasteners per local building code requirements. For concrete curing applications, overlap seams by a minimum consistent with project specifications and weight or tape edges to prevent wind displacement. Keep the sheeting away from open flame and heat sources.
