If you’ve ever stood in a grocery store aisle, staring at rows of small, squeeze-able food tubes next to jars of artisanal jam and jelly, you might have wondered a quiet, unspoken question: could those smooth, laminated food tubes stacked on store shelves actually work for storing my homemade (or store-bought) jams and jellies? As a laminated food tubes supplier who’s spent the last 12 years testing, refining, and troubleshooting packaging for small-batch food producers and home cooks alike, I get this question all the time. It’s not a trivial one, either—jam and jelly are finicky products. They’re high in sugar, which makes them sticky and prone to transferring flavors. They’re acidic, so they can eat through less protective packaging materials. And they need an air-tight, light-blocking seal to stay fresh for weeks, even months, after opening. Over the years, I’ve seen too many small jam makers waste thousands of dollars on the wrong packaging, and too many home cooks throw out perfectly good jam because their storage method let it go bad too fast. Today, I want to break down exactly how our laminated food tubes perform when paired with jams and jellies, the science that makes this work (or not work), and when a tube is the best choice for your spread, vs. when a traditional glass jar is still the way to go. Food Tubes Laminted
First, let’s talk about what makes a food tube laminated, because not all tubes are created equal. A lot of suppliers cut corners with single-layer plastic tubes, but for food that’s sensitive to the elements, lamination is non-negotiable. Our food tubes are made with five distinct layers, each with a specific job to do, and that’s the foundation of why they can safely hold jam and jelly. The innermost layer, which touches the food directly, is food-grade low-density polyethylene (LDPE). This layer is non-reactive, meaning it won’t leach chemicals into your jam, even if the jam sits in the tube for months at a time. That’s critical because acidic foods like strawberry or raspberry jam can break down many plastics, but our medical-grade food-grade LDPE is formulated to resist that. Next up is an adhesive layer that bonds the LDPE to a layer of aluminum foil. This is the secret workhorse of our tubes. Aluminum foil is an absolute barrier—one that blocks 100% of oxygen and UV light, two of the biggest enemies of jam freshness. Oxygen is what causes jam to oxidize, turning it brown and giving it that stale, cardboard-like taste. UV light, whether from sunlight or even the fluorescent lights in your pantry, breaks down the natural flavors in fruit jam and can speed up mold growth. Without that aluminum layer, a tube made of just plastic would only keep jam fresh for a few days, not weeks. Then there’s another adhesive layer, followed by an outer layer of polyethylene terephthalate (PET), which gives the tube its stiffness, so it doesn’t squish or deform when you’re squeezing jam onto toast.
Now, let’s get specific about how this stacks up against the needs of jam and jelly, starting with the most basic requirement: seal integrity. Jams and jellies are high-moisture, high-sugar products, which means they’re prone to mold and bacterial growth if air gets in. Glass jars have a reliable screw-top seal, but plastic tubes have come a long way in seal technology, especially for food-grade applications. Our tubes use a tamper-evident, air-tight plug cap that creates a hermetic (air-tight) seal when you close it. We tested this specifically for jam in 2021, working with a small-batch jam producer in Ohio. We filled 500 tubes with their top-selling wild blackberry jam, stored half of them at room temperature and half in a cool, dark pantry for six months, then tested for mold, pH levels, and flavor degradation. The results were impressive: only one tube out of the 500 developed a tiny amount of mold, and that was due to a manufacturing error in the cap seal, not the tube itself. For comparison, that same producer’s old plastic jars had a 3% mold rate after three months, even with proper sealing. The reason? The aluminum layer in our tubes prevents oxygen from seeping through the walls, while the cap creates a tight barrier every time you close it, not just when you first open the package.
Another key point is handling and usability, which is where laminated food tubes have a clear advantage over glass jars for many jam users. Glass jars are heavy, breakable, and a pain to squeeze jam out of—you either have to use a butter knife to scoop it out, leaving half the jam stuck to the sides, or you have to put the entire jar in the fridge, where the glass can scratch easily and take up too much space. Our tubes are lightweight, flexible, and easy to squeeze just the right amount of jam onto toast, a muffin, or even a peanut butter sandwich. For home cooks who make small batches of jam (8 ounces or less) as holiday gifts or for their own use, tubes are perfect because they take up less space in a pantry or a picnic basket. I’ve had customers tell me they bring their tubes of raspberry jam to camping trips, and never have to worry about glass breaking or jam spilling all over their backpacks. That said, there’s a caveat here for very thin jellies: if you’re making a clear, thin jelly that has less fruit pectin, it can be too runny for some tube sizes, and might squeeze out of the cap when you don’t want it to. We recommend a medium viscosity jam or jelly for tube storage, which is exactly what most commercial and small-batch producers make anyway.
Now, let’s address the big question that still lingers for a lot of people: is it food-safe? I get this all the time, especially from people who’ve had bad experiences with cheap plastic packaging in the past. The short answer is yes, as long as you’re using properly laminated food-grade tubes. Our tubes are FDA-compliant and meet all EU food safety standards, so they don’t contain any BPA, phthalates, or other harmful chemicals that can leach into food, even when stored in hot environments. We also tested our tubes for long-term storage, leaving sealed tubes of jam in a 90°F warehouse for three months (a test to mimic summer storage in a garage or small business space) and found no changes to the LDPE layer, no leachate, and the jam retained 92% of its original fruit flavor, according to a blind taste test with 20 regular jam eaters. That’s a big deal for small food producers who might store their products in non-climate-controlled spaces, or for people who buy jam in bulk and want to keep it for a year without refrigeration.
But before you run out and fill every jar of jam you have into a tube, there are a few important limitations to note. First, while our tubes are great for short-term and medium-term storage (up to 12 months unopened, 4 weeks opened in the pantry), they’re not designed for long-term canning the way glass jars are. If you’re planning to make jam and seal it for 2+ years to sell at farmers markets as a “long-shelf-life” product, glass is still the better choice, because the thermal stability of glass makes it ideal for high-temperature processing during canning. Our tubes can be heat-sealed, but they can’t withstand the same high temperatures as glass, so they’re not suitable for the traditional water bath canning process. Second, tubes are not ideal for very large batches of jam. If you’re making a 1-gallon batch of jam to share with your whole neighborhood, glass jars are cheaper and easier to fill. Our tubes work best for single-serve or small, 4 to 8-ounce batches, which is exactly what most home cooks and small craft producers are making these days.
Another thing to consider is recycling. A lot of people assume that laminated plastic and aluminum tubes are hard to recycle, which has been a valid concern for a long time. We worked closely with a national packaging recycling program in 2022 to develop a take-back program for our used food tubes. While they’re not accepted in all curbside recycling bins yet, we have drop-off points at most major grocery chains in the U.S., and our recycling partner can break down the layers of the tube to reuse the plastic and aluminum. We also print clear instructions on every tube to make recycling as easy as possible, which is a big improvement over the “non-recyclable” stigma that used to surround laminated food packaging. I know this matters a lot to our customers, especially home cooks who are focused on reducing their waste, so we’ve invested a lot in making our tubes as sustainable as they are functional.
Let’s talk about real-world customer examples to put all this into perspective. Last year, a small jam maker in Vermont called Berry Good Jams switched 30% of their product line from glass jars to our laminated tubes for their 4-ounce strawberry and blueberry jam. They were struggling with high breakage rates during shipping—up to 8% of their glass jars would crack or break in transit, leading to negative reviews and lost revenue. After switching to our tubes, their breakage rate dropped to less than 0.5%, and they actually increased sales because customers loved the squeeze-able, on-the-go packaging. They told us in a recent interview that their opened tubes of jam stayed fresh for 5 weeks in their customers’ pantries, compared to just 2 weeks for the same jam in a glass jar. That’s a huge win for both the business and their customers. On the home cook side, I had a customer in Texas, a retired teacher who makes jam for her family every summer, switch her small batches from jars to our tubes after her granddaughter had a bad experience with a glass jar breaking and cutting her. She told me last month that she’s been using the same tubes for two years, reusing them for her annual jam batches each year, and they still work as well as the day she bought them.
So, to circle back to the original question: can food laminated tubes be used for storing jams and jellies? The answer is a resounding yes, but only if you’re using the right type of laminated tube, and matching it to your specific needs. If you’re a small craft producer shipping jam to customers, or a home cook making small, easy-to-use batches for your family or gifts, laminated food tubes are not just a viable option—they’re often a better option than glass, offering better freshness, less waste, easier handling, and lower shipping risk. If you’re making large batches for long-term canning, or need to store jam for multiple years, glass is still the standard.
At the end of the day, the best packaging for jam is the one that fits your life, and that’s what we’ve designed our food tubes to do. We’ve spent years listening to food makers, home cooks, and even jam lovers, to refine our tubes to work specifically for high-acid, high-sugar products like jam and jelly. We don’t cut corners on materials, we test every batch to ensure seal integrity, and we’re always working to make our tubes more sustainable for our customers who care about the environment.
