The H020 is a 5 gallon clear LDPE plastic collapsible water container. This container is flexible and malleable. When filled, it assumes the shape of a cube. When empty, it can be folded in on itself. It has a threaded neck finish so that it can be affixed with a cap or spigot. Also available are a carton (item M057-5) and carton handle (item M058). This item does not come with a lid. Low density polyethylene (LDPE) is marked with the resin identification code of 4. LDPE has high tensile strength and low density. This makes it very tough and "squeezable." LDPE has medium clarity, good chemical resistance, high impact resistance, and high scratch resistance. 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.
