At 20 x 100 ft, this roll of 6 mil polyethylene film is sized for covering a large greenhouse structure or several smaller hoop houses from a single roll. The 0.15 mm thickness holds up against tearing during stretching and installation while resisting UV radiation, so the cover keeps its strength through a full growing season instead of turning brittle. It blocks UV rays on hot days while helping keep warmth in on cold ones, and its coating cuts down on dust settling on the film so plants underneath still get clear light for optimum growth. Because the film unfolds and re-rolls easily, cutting and fitting it over hoops or frame rails is a manageable do-it-yourself job without special tools. The same tear resistance and weather durability make this sheeting handy well beyond the garden, serving as a protective barrier for construction, masonry, and landscaping projects that need a large, tough plastic sheet on hand.
