The H004NT is a 5 gallon natural-colored HDPE plastic tight-head container with handle. This container is square shaped and is equipped with a heavy-duty carrying handle. On the back end of the handle is a vent lid (included) that when unscrewed permits a more even flow when used with a spigot. Also included is a 70 mm lid with a built-in 3/4" spigot adapter. This is a natural (translucent) container. The wall thickness of the H004NT is 0.75mm or 0.03 inches. High density polyethylene (HDPE) is marked with the resin identification code of 2. HDPE has a high tensile strength, good resistance to chemicals, good impact resistance, highly rigid, and highly scratch resistant. Natural-colored containers are not actually colored. This is the natural color of the plastic, which is a milky translucent color. This translucent color shows product level, or how full (or, if you're a pessimist, how empty) the container is.
