If you’ve ever rummaged through a kitchen cabinet for a bag of rice that turned out to be expired, or grabbed a jar of pickles only to realize you confused it with the jar of olives you bought two months ago, you know how frustrating poor labeling can be. As a storage jar supplier, I’ve watched customers skip over the most important part of their new jars: the label. I get it—you’re excited to unbox your jars and fill them with dried goods, snacks, or homemade treats, and grabbing a marker and scribbling something quick on the lid seems fast enough. But over the years, I’ve seen firsthand how intentional labeling can save you time, reduce food waste, and even make your space look more organized. Today, I want to break down how to label a storage jar the right way—no fancy design skills required, just practical, science-backed tips that work for every type of jar and every space. Storage Jar
First, let’s talk about the core reason labeling matters. Food waste is a huge, often overlooked problem, and date-related spoilage is a top cause. The U.S. Environmental Protection Agency (EPA) estimates that food and packaging account for over 30% of municipal solid waste in the U.S., and much of that waste stems from confusion about when items were stored. I recently had a customer reach out to me saying she threw out three jars of homemade jam, all within a week of each other, because she couldn’t remember when she canned them. That’s the kind of avoidable mistake we want to help with. A good label doesn’t just tell you what’s in a jar—it tells you when it was opened, when it needs to be used by, and even storage notes that keep your food fresh longer. It’s not just about organization; it’s about preserving the food you worked hard to make or buy.
Before you even pick up a marker, you need to match your label method to your jar and its contents. Not all storage jars are the same, and what works for a glass jar holding sugar won’t work for a plastic jar holding leftover pasta, or a jar that goes in the fridge vs. the pantry. Let’s break this down by jar type and use case, because one size definitely doesn’t fit all.
If you sell or use airtight glass jars—our best-selling line, by the way—these are perfect for dry goods like flour, rice, and grains. These jars live in the pantry, so they’re exposed to humidity, heat, and occasional spills. The last thing you want is a label that smudges or peels after a few months on a shelf. For glass jars, I recommend either a waterproof, fade-resistant vinyl label or a laser-printed paper label sealed with a clear acrylic coating. The key here is to choose a label that adheres well to glass, but won’t leave a sticky residue when you want to re-label the jar later. I always tell customers to avoid regular inkjet labels for glass—they bleed if they get even a tiny bit of moisture on them, which is exactly what happens when you pour flour in a hurry. For glass jars, I also suggest placing labels on the side or front of the jar, not the lid. Lids are often moved, opened, and washed, so a label on the side stays in place longer.
For plastic storage jars—great for things like nuts, trail mix, or frozen berries—these are often lighter, some go in the fridge or freezer, and many are dishwasher-safe. The biggest challenge here is adhesion: plastic is non-porous, so labels can slide off easily if not applied right. For plastic jars, either the same waterproof vinyl labels work, but you’ll want to wipe the jar surface with rubbing alcohol first before applying—this removes any oil or dust that keeps the label from sticking. Another trick I’ve learned is to buff the label firmly after applying, to push out any air bubbles and make sure it’s adhered properly. If your plastic jar is going in the freezer, you’ll want a label that’s designed for cold temperatures—regular labels will crack and peel when exposed to freezing temps. I once had a customer come back saying all her freezer labels fell off after a month, and that’s because she used paper labels instead of cold-resistant vinyl.
Then there are jars used for liquids or moist goods—like homemade dressings, infused oils, or pickles. These are usually glass, but they live in the fridge, so they get condensation and occasional spills. For these jars, I recommend a label that’s not just waterproof, but also resistant to oil. Oil and water can seep under paper labels, making them curl and fall off. The acrylic seal on vinyl labels blocks both, so that’s a safe bet here. I also suggest labeling these jars immediately after filling them, before you put them in the fridge. Once condensation starts, it’s much harder to get a marker to write clearly, and the ink will smudge.
Now, what do you actually write on the label? This is where most people go wrong—they write “coffee” and stop, but there’s so much more useful information. Let’s keep this simple, but cover the essentials that will save you stress later. The magic of a good label is that it answers three questions at a glance: What is it? When did you put it in the jar? And when should you use it by?
First, the name of the item. Be specific, not vague. Instead of “nuts,” write “roasted almonds (unsalted)” or “peanut butter (natural, no added sugar).” This is especially helpful if you have multiple similar jars on your shelf. I’ve seen customers come to me saying they had three jars labeled “beans” and couldn’t tell which was black bean chili and which was canned kidney beans. Specificity avoids that confusion. If it’s a homemade item, add a quick note like “grandma’s pasta sauce” or “oatmeal raisin cookies (baked 10/15)” that’s extra helpful for later.
Next, the date. This is the non-negotiable part. You don’t need to write the full month and year, though that works too—even just the day and month is enough. If you can, write the date you filled the jar, not the expiration date. Why? Because expiration dates are often guidelines, but knowing exactly when you stored something lets you follow your own common sense. For example, homemade jam will last 12 months sealed in a pantry, but only 3 months once opened in the fridge. If you write the date you opened it, you won’t have to guess. I always tell customers to use a consistent date format, like MM/DD or DD/MM, so there’s no confusion when you’re checking multiple jars.
Then, add quick use or storage notes. This is the part that turns a good label into a great label. For example, if you have a jar of rice that should be stored in a cool, dry place, you can write “keep in pantry, not near stove.” Or for a jar of leftover soup, write “reheat on stovetop, microwave for 2 mins max.” For items that should be frozen, add “freeze after opening” or “best used within 2 months of freezing.” Small notes like that eliminate the guesswork that leads to food waste.
Now, let’s talk about label placement and design, because even the best label is useless if you can’t see it. First, avoid putting labels on lids—lids get stacked, moved, and washed, so a lid label will get damaged or lost. Put labels on the front or side of the jar, where they’re visible when the jar is sitting on a shelf. If you have jars stacked on top of each other, a label on the upper side of the jar will be visible from the front, so you don’t have to pull jars out to read them. For small jars, you can use a smaller label that fits the surface, or write directly on the jar with a oil-based marker that’s designed for glass or plastic. I’ve tried regular markers and they smudge, but oil-based markers are permanent and work on most jar surfaces.
If you’re someone who loves a neat, uniform look, you can also make your own labels. You don’t need to be a graphic designer—just use a free tool like Canva to make simple labels with consistent fonts. Matching labels make your pantry look intentional, and it’s easy to print them on the vinyl labels I mentioned earlier. I even have customers who buy our bulk storage jars and use custom labels for their coffee bar or snack station, which makes the whole space look more put-together. The key here is to not overdo it—keep the font simple, so it’s easy to read from a distance. Fancy script fonts might look nice, but if you have small text, you’ll strain to read it across the room.
Let’s also cover some common mistakes I’ve seen customers make, because these are easy to avoid. First, using the wrong marker. As I said, regular ballpoint pens or water-based markers will smudge on glass and plastic, especially if the surface is even a little damp. Oil-based markers work, or you can use a chalk marker if you like a more temporary look for jars that you re-label often. Second, not testing the label before applying it. I’ve had customers tell me they used a label that looked great on paper but peeled off after a week on their plastic jar. Test a small corner of the label on an inconspicuous part of the jar first, to make sure it adheres. Third, waiting to label until the jar is almost empty. By then, you’re in a hurry to fill the next jar, and you’ll skip important details like the date. Label as soon as you fill the jar—it takes 10 seconds and saves you hours of hassle later.
Another thing that’s important: re-labeling when you refill a jar. It’s tempting to just top off a jar of flour and leave the old label, but that old date is irrelevant now. Every time you empty and refill a jar, remove the old label and add a new one. If you have jars that you use for rotating stock—like rice or pasta—this is especially important. Rotating stock means using the oldest item first, so the new label with the most recent date reminds you that the older jar should be used first. This simple practice reduces food waste by a lot, because you don’t end up with jars of rice that have been sitting in the back of the pantry for two years.
I also want to touch on the science behind label longevity, because it’s not just about sticking—it’s about resisting environmental factors. When a label is exposed to UV light from sunlight, it can fade over time. If you have jars in a sunny window sill (like herb jars or tea jars), use a label that’s UV-resistant, so the text doesn’t wash out after a few months. For jars in high-humidity areas, like near the sink or dishwasher, use a label that’s rated for high humidity, so it doesn’t peel at the edges. This is why we offer a range of label options for our storage jars—we’ve tested different materials to make sure they hold up to real-world use, not just perfect lab conditions.
At the end of the day, labeling a storage jar is a small task, but it has big payoffs. It saves you from digging through cabinets, it reduces food waste, and it makes your kitchen or pantry feel more organized. Over the years, I’ve heard so many customers say that labeling their jars changed how they use their kitchen—they waste less food, they can find what they need faster, and their space looks more intentional.
