This heavy-duty black plastic sheeting is made from polyethylene and designed for broad indoor and outdoor coverage. Its 6 mil thickness helps resist tearing, weather exposure, and demanding jobsite or garden conditions. The opaque black surface helps block sunlight to reduce weed growth and protect covered areas. It can be used for crawl space vapor barriers, insulation, moisture protection, dust control, and general-purpose covering. The roll is also easy to cut for custom installation needs.
