How to ensure the hygiene of food packaging tubes?

If you’ve ever picked up a tube of your favorite nut butter, squeeze a dollop of toothpaste onto your brush, or grabbed a tube of tomato paste from the back of your pantry, you’ve probably never stopped to think about the journey that package took before it held that food. As a food packaging tube supplier, that journey is my entire world—and over the last 12 years in this role, I’ve learned that one tiny misstep in hygiene can turn a perfectly good product into a health risk, or worse, erode the trust that makes customers come back. Food Packaging Tubes

I still remember a call I got from a small artisanal jam maker three years ago. They’d had a batch of jars and tubes rejected by a regional food safety inspector, and they were heartbroken. They’d spent months perfecting a new raspberry jam, and the rejection threatened to derail their holiday sales. When I visited their facility to help diagnose the problem, I learned they’d been cutting corners on the final cleaning step for their packaging tubes, skipping a critical rinse cycle to save time during a busy production week. That experience drove home a truth I carry with me every day: hygiene isn’t just a box to check in food packaging—it’s the foundation of everything we do.

So, how do we ensure the hygiene of food packaging tubes? It’s not a single fix, and it’s not something that happens in a single part of the supply chain. It’s a series of deliberate, science-backed steps that start long before a tube is even printed, and continue right up to the moment it’s filled with food. Let me break down what we (as a supplier) do, and what our customers need to know to keep their products safe.

First, the raw material selection. I can’t stress this enough: not all plastic is created equal, especially when it comes to food contact. The tubes we manufacture are almost always made from LDPE (low-density polyethylene) or a multi-layer co-extruded plastic, and every roll of plastic we receive comes with a Material Safety Data Sheet (MSDS) that confirms it meets FDA and EFSA standards for food contact. We never use recycled plastic for the inner food-contact layer, even if it means paying a little more for virgin resin. Recycled plastic can carry hidden contaminants—tiny bits of old food, cleaning chemicals, or even microplastics that leach out over time. For example, a 2022 study in the Journal of Food Protection found that recycled plastic packaging had 17 times more potential for migrant contaminants than virgin food-grade plastic, especially when exposed to acidic or high-fat foods. That’s why we source our inner layers only from suppliers that specialize in food-grade resins, and we test every batch of incoming plastic for extractables and leachables before it ever touches our production equipment.

Next, the production process. This is where a lot of suppliers cut corners, and where hygiene can go off the rails fast. Our production line operates in a controlled environment: the extrusion, printing, and trimming stages are all done in a room with positive air pressure, so outside dust, pollen, or other airborne particles can’t get in. We wear lint-free lab coats, hairnets, and gloves at all times while on the production floor, and every single piece of equipment that touches the plastic tubes is cleaned and sanitized at the start of every shift, and between different product runs.

The extrusion process itself is another critical point. When we melt the plastic to form the tube, we heat it to a specific temperature range—usually between 180 and 220 degrees Celsius—that’s high enough to kill any potential bacteria or mold that might be trapped in the resin, but not so high that it breaks down the plastic and releases harmful chemicals. We also test each new tube lot for residual monomer levels after extrusion; residual monomers are the small molecules that make up plastic, and if they’re not fully bonded during extrusion, they can migrate into food. The FDA has strict limits on these levels, and we never ship a lot that comes close to exceeding them.

Printing is another step where hygiene matters, even though it’s an exterior process. All our inks are food-grade, water-based, and non-toxic—no solvent-based inks that can leach into food through the plastic. The printing plates we use are sanitized with a food-safe detergent before each run, and the area where printing happens is separate from the tube forming area to prevent any ink overspray from getting on the inner surface of the tubes. I’ve seen too many instances where a printer’s overspray contaminated tube interiors, leading to a full batch recall, and that’s a mistake we will never make.

Once the tubes are formed and printed, they go through a final cleaning and inspection step. This is where our jam-making friend went wrong, so we take this part extremely seriously. We use a two-step cleaning process: first, a mild, phosphate-free detergent rinse to remove any residual plastic dust or production debris, followed by a rinse with potable, reverse-osmosis filtered water. The water we use is tested daily for total coliform bacteria, E. coli, and other pathogens, so there’s no chance we’re using contaminated water to clean the tubes. After rinsing, the tubes are dried in a clean air tunnel that’s filtered with HEPA filters to remove 99.97% of airborne particles—no dust, no lint, no nothing.

Then comes the inspection. We use both manual and automated checks to make sure every tube is perfect. Automated vision systems scan each tube for scratches, holes, or misprints, and our quality control team does a random check of 5% of each lot to make sure the inner surface is smooth and free of any debris. We also do a microbial test on every lot: swabs from the inner surface are tested for aerobic plate count, yeast, and mold, and we require that all levels are below 10 CFU (colony-forming units) per square centimeter. That’s a standard we set higher than most regulators, because we know that food businesses rely on us to deliver a product that’s safe for their customers.

But here’s the thing: hygiene isn’t just our responsibility as a supplier. It’s also the responsibility of the companies that fill the tubes with food. I always tell our customers that the tube is only part of the equation—how they store, fill, and close the tubes matters just as much. For example, we recommend that our customers store empty tubes in a cool, dry place, away from direct sunlight, because UV rays can break down plastic over time, creating tiny cracks where bacteria can hide. We also advise them to sanitize the filling equipment before each use, and to make sure their production floor is kept clean and dry to avoid cross-contamination.

I recently worked with a small sauce maker in Texas who was having issues with mold growing in their filled tubes. They were storing the filled tubes in a warm warehouse next to their cooking equipment, and the heat was causing the plastic to sweat slightly, creating a moist environment inside the tube. Once we talked about storage conditions, they moved the tubes to a temperature-controlled warehouse, and the mold problem went away within a month. That’s a great example of how the tube’s hygiene works hand in hand with the customer’s practices.

Another important point is traceability. If there’s ever a problem with a lot of tubes, we need to be able to track every single one back to its raw material batch, production date, and cleaning records. That’s why every tube lot has a unique batch number, and we keep detailed records for every single lot we manufacture. We store these records for at least three years, which is longer than the typical shelf life of most food products, so if a customer has an issue, we can quickly investigate and resolve it.

I also want to talk about regulatory compliance. As a supplier, we don’t just meet the minimum requirements—we go above and beyond. We regularly audit our facilities against FDA, EFSA, and BRC (British Retail Consortium) standards, and we have a third-party auditor come in once a year to verify our processes. We also stay up to date on new research in food packaging hygiene; for example, recent studies have shown that even “food-safe” plastic can release microplastics over time, especially when exposed to hot foods or acidic ingredients. Because of that, we’ve started testing our tubes for microplastic release, and we’ve adjusted our production process to minimize this risk, even though it’s not currently required by regulators.

I know that for many small food businesses, cost is a big concern. When I talk to new customers, they often say, “Can’t we use cheaper tubes to save money?” My answer is always the same: “The cost of a few extra cents per tube is nothing compared to the cost of a recall, a lost customer, or even a legal issue.” The jam maker I mentioned earlier spent thousands of dollars reprocessing their batch and lost hundreds of holiday sales, all because they cut corners on a cheap, easy step. As a supplier, we work hard to offer competitive prices, but we never compromise on hygiene—because that’s the value our customers actually need.

At the end of the day, food packaging tubes are more than just a container. They’re a promise: that the food inside is safe, that it will stay fresh, and that it won’t make someone sick. For 12 years, I’ve taken that promise seriously. We don’t just make tubes—we build trust, one lot at a time.
