A 55 gallon plastic drum is a storage or shipping container made of a high density industrial strength polymer with thick walls that provide endurance, strength, and longevity for the containment of a wide variety of substances and materials. Their seamless construction makes them ideal for the safe and secure storage and containment of harmful and hazardous solids and fluids.
The rigidity, durability, and toughness of 55 gallon plastic drums has made them a major asset to distributors, shippers, warehousing operations, and other forms of shipping and storing facilities. This singular attribute has enhanced and broadened their use in the chemical, food, and manufacturing industries.
The process for the manufacturing of 55 gallon drums begins with the selection of the correct high density polymer, which may be low density for certain types of drums. Regardless of the type of drum, the polymers for drums start as a resin or pellets that can come from recycled plastic material or newly formed resin from the resin manufacturing process.
The three processes used to produce 55 gallon plastic drums are rotational, injection, and injection blow molding with injection blow molding being the most common and efficient. In the blow molding and injection molding processes, resin pellets are melted before being inserted into the mold cavity. Rotational molding uses a resin powder that is melted in the heated mold.
Though resin pellets are clear or white, they can have colorant added to give 55 gallon plastic drums an assortment of colors. In most cases, the drums are white, yellow, or blue with other colors being available from producers upon request. In every one of the different manufacturing processes, the resin pellets are melted before being processed. The melted resin is formed into a parison, a hollow tube.
A key to the longevity of 55 gallon plastic drums is the addition of a UV inhibitor to the resin pellets since outdoor exposure to sunlight can degrade plastics in a short time. The best color used to fight UV damage is black with white being the least effective.
The most common process for the manufacturing of 55 gallon plastic drums is blow molding. The name of the process is a description of it since it involves injecting the parison into a mold, which is blown and forced by pressure to the sides of the mold. There are three forms of blow molding, which are extrusion, injection, and injection straight. The difference between the three types is based on how they form the parison, its size, and how it moves between the halves of the mold.
The plastic extruder is an essential aspect of the heating process since it evenly heats the pellets such that the pellets in the barrel are heating to the exact same temperature. This is critical for avoiding errors and deformations in the final 55 gallon plastic drum.
The parison created by the extruder is fed into the open mold that is in the shape of the 55 gallon plastic barrel. As can be seen in the diagram below, the parison is a long tube in the shape of a drape or curtain that hangs between the two sections of the die.
Of the many materials available for product production, plastics are the most used and adaptable for the manufacturing of industrial products as well as products for home use. The durability, strength, and flexibility of plastic has made it an essential part of a wide variety of products including plastic drums for storage, transport, and shipping use.
Unlike the plastics available for conventional products, the types of plastics for the manufacturer of drums must be of high endurance and have the ability to withstand stressful use. These conditions require polymers with specific mechanical properties and characteristics.
For the manufacturing of 55 gallon plastic drums, the types of plastics must be exceptionally resilient and strong. The ones that are commonly used include polyvinyl chloride (PVC), high-density polyethylene (HDPE), nylon, and polystyrene. These types of plastics have been used since the 1960s as an alternative to making drums from steel.
High-Density Polyethylene is a thermoplastic polymer that is strong, durable, lightweight, and chemically resistant. HDPE is made from petroleum using a process that is known as cracking where petroleum is exposed to intense heat to create ethylene gas. During the process, the ethylene gas molecules attach to polymers to form polyethylene. The sludgy polyethylene is further processed to form granules to produce the polymer material.
Nylon plastic is used to produce 55 gallon plastic drums due to its nonreactivity, low moisture absorption, and resistance to chemicals. Plastics made from nylon are known as polyamides, which is a thermoplastic. It is made by reacting together two molecules through the use of heat and pressure to form sheets that are shredded into chips of raw nylon plastic.
Polystyrene is made through the polymerization of styrene. When it is copolymerized with other forms of polymers, it becomes harder and more rigid, which broadens its usefulness in the manufacturing of plastic drums. The styrene in polystyrene is produced by a reaction between ethylene and benzene in the presence of aluminum chloride, which makes ethylbenzene from which styrene is made. At one time, polystyrene was made from chlorofluorocarbon, a process that has been banned for environmental reasons.
Polystyrene cups, containers, and trays are some of the ways that most people see polystyrene. When it is blended with other polymers, it hardens and becomes more rigid for the production of 55 gallon plastic drums.
The discussion of the use of 55 gallon plastic drums goes in a wide variety of directions considering the many uses people have found for these adaptable and sturdy containers. What tends to be ignored in the discussion of the use is the main reason for their existence, which is as a storage, shipping, and transport means for liquids, powders, granular materials, chemicals, and food products. These primary functions are the reason they have become so popular in the last sixty years.
The revelation of high density plastic drums has become a major asset for manufacturing and industrial operations. Their durability and strength have made them a practical solution to otherwise dangerous storage conditions.
For a plastic drum to be used for food storage or transport, it has to meet the standards established by the Food and Drug Administration for cleanliness and sanitary condition. The term food grade refers to plastics that can come in direct contact with food at any stage of its processing, harvesting, production, or packaging. In the case of 55 gallon plastic drums, they have been determined to be safe for long term storage and shipping of foodstuffs.
To receive the designation as food grade, 55 gallon plastic drums are tested, examined, and analyzed to ensure that any form of dyes or chemicals that may be harmful to humans are not present. Once it is determined that a drum is food grade, it can be used to store bulk foods, grains, liquids, and cooking oils.
The pharmaceutical industry relies on 55 gallon plastic drums due to their durability and resistance to the effects of corrosive substances. Drums selected for use in the pharmaceutical industry are made of high density, FDA compliant polyethylene and can withstand the effects of chemicals and hazardous materials. 781b155fdc
