Frequently Asked Questions
What is an industrial drum?
What is an open-head drum?
Open-head plastic drums, which have fully removable heads, are used to ship dry and viscous (e.g., adhesives) products as well as free flowing liquids that are not Department of Transportation (DOT) regulated. The open-top sub-type is sealed by a mechanical ring clamp (concave inwards) that exerts sufficient pressure to hold many non-volatile liquids and make an air-tight seal against a gasket, as it exerts force inward and downward when tightened by a normal three-quarter inch wrench or ratchet wrench. Many drums are used to ship and store powdered products as well as liquids, such as plastic beads for injection molding and extrusion, and purified industrial grade powders like cleansers, fertilizers, and powdered aluminum.
What is a closed-head (tight-head) drum?
Tight-head plastic drums typically have two threaded openings in the top head and are used to transport free-flowing liquids. Plastic closed-head drums are the preferred shipping container for caustic and acidic materials because the solid, one-piece construction makes it more attractive for storing or transporting hazardous materials, ensuring against leakage or spills. Chemicals frequently transported in closed head plastic drums include: acetic acid, acrylic acid, ethylene glycol, methanol, mineral spirits, and sulfuric acids as well as caustic chemicals because they do not corrode the plastic drums. Other non-regulated chemicals, dyes and adhesives that utilize plastic drums are agricultural chemicals, cleaning liquids, pharmaceuticals, paints and coatings, photographic chemicals and reagent solutions.
What is an IBC?
An Intermediate Bulk Container (IBC) is a container constructed of plastic with steel reinforcing and is used for storage and transportation of goods. IBCs have pallet-like bases so that forklifts can move them. IBCs can be stacked vertically and typically weigh approximately 140 pounds. Encore Container reconditions composite IBCs with plastic bottles, steel and plastic cages, and with steel or wood pallets.
Is Encore Container subject to regulations?
Encore Container's operations are subject to regulations the Department of Transportation and OSHA. The DOT regulates the markings on containers to ensure that containers meet certain packing and durability criteria suitable for the products being packed in them. Encore Container complies with all OSHA rules and regulations through a comprehensive health and safety program.
How strong is a drum made of 100% plastic resin regrind?
Encore Container manufactures plastic drums from 100% plastic resin regrind. This regrind is recycled high density polyethylene (HDPE), offering financial advantages over "virgin" resin. Using a "drum crusher" device which measures force exerted on a drum, Encore Container drums made of regrind are shown to be more durable than other leading brands' models made from virgin resin.
What is post consumer regrind (PCR)?
Encore Container produces its own regrind material from existing drums. Regrind results from drums that are cleaned and shredded into small plastic components. This regrind is again washed before a pelletizing process heats and forms it into small, uniform pellets. This pelletized regrind is then sent to a blow molder which then forms the drums.
What happens in the plastic drum manufacturing process?
The drum manufacturing process involves grinding drums, then washing regrind. Equipment used includes a blow mold machine, extruder, shredder, grinder, resin wash line, and chiller. In the re-pelletizing process, the irregular chunks of plastic are melted down, and sent through a process that makes small uniform pellets which add control when making the drum.
