The bags feature a multi-layer blown polyethylene film which enhances strength and resistance to punctures and tears. The outside is white to reflect sunlight, inside black for opacity, helping with temperature and light control. Sizes vary: e.g. 8-foot to 14-foot diameter, and lengths from ~100 ft up to ~500 ft. Suitable for large farms needing flexible, temporary bulk storage of harvested forage, grain, or feed. Storage and handling are easier due to lay-flat design, which helps when loading onto bagger tunnels. Can significantly reduce spoilage losses vs open pile or unprotected storage.
