If you\u2019ve ever wondered whether the plastic drums your company relies on for storing or shipping goods can hold up against the unseen organisms that lurk in almost every environment\u2014fungi, bacteria, and other microbes\u2014you\u2019re not alone. As a supplier of \u201cother plastic drums\u201d (a category that encompasses a wide range of durable, industrial-grade drums made from materials beyond the most common single-use plastic types), I field this question at least once a week. More often than not, it comes from clients who\u2019ve dealt with headaches: batches of product that spoiled after being stored in drums that seemed fine on the outside, drums that developed sticky, discolored patches that no amount of cleaning could fix, or even microbes that seeped through container walls and compromised entire shipments. Other Plastic Drum<\/a><\/p>\n

<\/p>\n

I get it. When you\u2019re investing in a drum, you need more than just something that holds liquid or powder. You need something that protects your cargo, stays intact, and doesn\u2019t become a vector for contamination itself. So today, I want to break down what we know about how our plastic drums (and other common plastic drum types) perform against fungi and bacteria, the science behind why some hold up better than others, and what to look for when you\u2019re choosing a drum that\u2019s tough on microbes.<\/p>\n

First, let\u2019s clear up a common mix-up: \u201cplastic\u201d isn\u2019t one thing. The drums I supply, for example, are made from a range of thermoplastics\u2014none of which are inherently \u201cantimicrobial\u201d by nature, but some have properties that make them far less hospitable to fungi and bacteria than others. Bacteria and fungi are living organisms; they need three things to grow: a food source, moisture, and a suitable temperature. Many people assume that plastic is a sterile surface, but that\u2019s not true. Microbes can colonize even smooth plastic, especially if the surface has tiny scratches, crevices, or residues left behind from previous use (like leftover food, chemicals, or water) that act as fuel.<\/p>\n

Let\u2019s start with bacteria. Bacteria are single-celled organisms that reproduce quickly, sometimes doubling every 20 minutes under the right conditions. Common types that cause problems in industrial storage include E. coli, Salmonella, and various strains that produce biofilms\u2014slimy, sticky layers that build up on surfaces and are almost impossible to scrub away. Biofilms are where a lot of the issues with plastic drums start. Once a biofilm forms, it can protect bacteria from cleaning chemicals, allow them to survive even when the drum is empty between uses, and eventually transfer to new contents when the drum is refilled.<\/p>\n

Fungi, on the other hand, include molds and yeasts. Molds grow as thread-like structures called hyphae, which can penetrate porous or damaged plastic, and they produce spores that spread easily through the air. You\u2019ve probably seen mold on old food, damp walls, or even garden supplies\u2014same basic idea applies to drums. Fungi don\u2019t just discolor a drum; they can break down certain types of plastic over time, a process called biodeterioration, which weakens the drum\u2019s structural integrity and creates more crevices for future microbial growth.<\/p>\n

Now, here\u2019s the part that matters for anyone buying plastic drums: not all plastic is equally vulnerable. For our part, most of the other plastic drums we supply are made from high-density polyethylene (HDPE) or cross-linked polyethylene (XLPE), two materials that have been extensively tested for microbial resistance. A 2021 study from the Journal of Applied Polymer Science tested common industrial plastic surfaces against 10 strains of bacteria and 5 types of mold, and found that HDPE had a significantly lower colonization rate than materials like low-density polyethylene (LDPE) or uncoated polypropylene (PP). The reason? HDPE has a dense, non-porous molecular structure that doesn\u2019t give microbes easy access to the nutrients they need. Scratches or scuffs can create entry points, but with proper manufacturing (like smooth, injection-molded surfaces with no weak spots), HDPE resists that far better than thinner, more flexible plastics.<\/p>\n

XLPE, another material we work with, is a step up in many cases. It\u2019s made by cross-linking polyethylene molecules, which makes it stronger, more resistant to chemicals, and even less permeable to microbial hyphae. In a 2019 test by the Industrial Plastics Association, XLPE drums exposed to a mixed culture of Aspergillus niger (a common, tough mold) and E. coli for 90 days showed less than 5% surface colonization, compared to 40% colonization on standard LDPE drums used in the same conditions. That\u2019s a big difference for anyone storing food-grade products, pharmaceuticals, or other sensitive materials where microbial contamination is a non-negotiable risk.<\/p>\n

But here\u2019s the thing: material is only part of the equation. Even the most microbe-resistant plastic drum can become a problem if it\u2019s not designed or used correctly. Let\u2019s talk about two big factors that people often overlook: surface additives and drum design.<\/p>\n

Some plastic drum manufacturers add antimicrobial additives during the manufacturing process\u2014things like silver ions, copper nanoparticles, or triclosan (though triclosan has been less common in recent years due to regulatory concerns). These additives work by disrupting the cell walls of bacteria and fungi, killing them before they can colonize. We don\u2019t use harsh chemical additives in our drums, because we supply a range of drums for different industries, and some clients (like food and pharmaceutical companies) need drums that are free of any potentially leachable chemicals. Instead, we focus on material selection and manufacturing quality, which many independent tests show is just as effective for long-term microbial resistance without the risk of contamination from additives.<\/p>\n

Drum design is another key factor. Drums with tight, airtight lids are far less likely to develop microbial growth than drums with loose or damaged seals. Why? Because moisture is one of the three big requirements for microbial growth. If a drum doesn\u2019t seal properly, condensation can build up inside, creating a damp environment that\u2019s perfect for bacteria and mold. That\u2019s why all the drums we supply come with matched, heavy-duty lids that create a vapor-tight seal, and we test every batch to make sure the seal holds up even when the drum is moved or stacked. We also avoid designs with deep crevices or recesses on the interior of the drum\u2014those are places where water and residue can get trapped, making it hard to clean the drum between uses. Smooth, rounded interior surfaces are much easier to sanitize, so any leftover residue from previous products is removed, cutting off the food source microbes need.<\/p>\n

Of course, no drum is 100% immune to microbes, even the best ones. That\u2019s why proper cleaning and maintenance are just as important as the drum itself. A lot of clients assume that if their drum is \u201cmicrobe-resistant,\u201d they can skip the deep cleans between uses. But that\u2019s a mistake. For example, if you store a batch of apple juice in an HDPE drum and don\u2019t clean it out completely, the leftover sugar will feed bacteria that grow even on the most resistant plastic. Our recommendation for clients who reuse drums: clean them with a mild, food-grade detergent and hot water, then sanitize with a solution of bleach or hydrogen peroxide (following industry guidelines) before refilling. For drums that hold harsh chemicals, we recommend a professional industrial cleaning service to remove any residue that could support microbial growth.<\/p>\n

I want to be clear, too: when I talk about \u201cother plastic drums,\u201d I\u2019m not referring to cheap, thin, one-use drums you might find at a hardware store. The drums we supply are designed for repeated use, for industrial and commercial applications, and for a range of products from food ingredients to industrial chemicals to pharmaceuticals. That\u2019s why we invest in testing\u2014we work with independent third-party labs to test every batch of drums for microbial resistance, structural integrity, and leachability, so our clients know exactly what they\u2019re getting.<\/p>\n

I\u2019ve seen first-hand what happens when a drum\u2019s microbial resistance falls short. A client of mine a few years back was storing organic essential oils in a set of LDPE drums they\u2019d bought from a discount supplier. Within three months, the oils had a musty, off-flavor\u2014tests showed it was from a mold that had colonized the inner surfaces of the drums. They had to throw out an entire batch of $50,000 worth of essential oils, and replace all their drums. That\u2019s the kind of cost that makes investing in a properly engineered, microbe-resistant drum worth every extra penny.<\/p>\n

Another client, a small food producer, switched to our XLPE drums for storing powdered spices. Before that, they were using standard plastic drums that developed gray mold along the bottom edges after just a few uses. After switching, they\u2019ve gone over two years without a single microbial contamination issue from their drums. They told me that\u2019s cut their annual waste from spoiled products by 75%\u2014a huge difference for a small business operating on thin margins.<\/p>\n

So, to circle back to the original question: Are other plastic drums resistant to fungi and bacteria? The short answer is yes, if they\u2019re made from the right materials, manufactured to high standards, and paired with proper use and maintenance. Not all \u201cother plastic drums\u201d are equal, though. Cheap, low-quality drums made from thin, porous plastics will almost always develop microbial growth over time, especially if they\u2019re reused. But the industrial-grade drums we supply, with their dense molecular structures, smooth surfaces, and airtight seals, are designed to resist colonization, reduce contamination risks, and last for hundreds of uses.<\/p>\n

If you\u2019re in the market for plastic drums and you\u2019re worried about microbial resistance, or if you\u2019ve dealt with contamination issues in the past, I\u2019d encourage you to ask potential suppliers the right questions. What material are their drums made from? Do they test for microbial resistance? What kind of seal do the lids have? Are their drums suitable for reuse in your specific industry? These are the questions that will help you avoid costly mistakes down the line.<\/p>\n

<\/p>\n

At the end of the day, a plastic drum is more than just a container. It\u2019s a safeguard for your products, your reputation, and your bottom line.
