Hey everyone, I’m Maya, and if you’ve ever stopped by our shop, you know we’ve been supplying kraft paper bags for over a decade. We get tons of questions from small business owners, crafters, and even regular folks who are trying to wrap their heads around sustainable packaging—especially when it comes to storing tricky items like candles. Today, I’m breaking down a question we hear all the time: Are kraft paper bags actually good for storing candles? Spoiler alert: It’s not a straight yes or no, and as someone who deals with these bags daily, I’ve seen both the wins and the missteps firsthand. Kraft Paper Bag
First, let’s talk about why candles are such a weird thing to store. Most of us think of candles as solid wax with a wick, but there’s way more going on under the surface. Wax—whether it’s paraffin, soy, or beeswax—has a funny relationship with moisture, air, and even light. If it’s exposed to too much humidity, the wax can get cloudy or even develop spots (we call those “bloom” in the industry, and it’s not just a cosmetic issue). Too much air, and the fragrance oils in the candle can evaporate over time, making it smell way less intense when you light it. And direct sunlight? That’ll melt the wax, fade the labels, and even weaken the wick before you ever get a chance to use it.
Now, how do kraft paper bags stack up against those issues? Let’s start with the good stuff, because that’s what makes our product a go-to for a lot of candle brands. First off, kraft paper is breathable. Wait, I know—if you’re storing something, you’d think airtight is better, but candles are the exception here. Plastic bags, even the “reusable” kind, trap moisture. I’ve had a customer tell me they stored a soy candle in a plastic bag for six months, and when they took it out, it was sticky and had that gross fuzzy mold on the bottom. Kraft paper lets a tiny bit of air circulate, so moisture doesn’t get trapped. That’s a huge win for preventing bloom, which is the number one complaint we get from candle makers.
Then there’s light protection. White paper bags? They let way too much sunlight in, and that’s bad for candles. But our natural brown kraft paper? It’s got a tight, dense weave that blocks most UV rays. We tested this a few years back—we put identical soy candles in a clear glass jar, a white paper bag, and our standard kraft paper bag, all on a windowsill for a month. The one in the clear jar was half-melted, the white bag one had a faded label and the wax was grainy, and the kraft bag one looked almost new. That’s not to say it’s 100% lightproof, but it’s way better than plastic or thin paper.
Another plus: kraft paper is non-reactive. Some packaging materials, like certain plastics or even metal tins with cheap coatings, can leach chemicals into candle wax over time. We’ve had customers use those random plastic bins from the dollar store for storage, and the next thing you know, the wax smells like plastic. Our kraft paper is just wood pulp, no weird additives, so it doesn’t mess with the candle’s scent or composition. That’s why so many small batch candle companies use our bags for shipping and short-term storage—they know their product stays safe.
But wait, it’s not all perfect. I’m not going to sugarcoat this, because if you’re storing candles long-term (like a year or more), kraft paper has some limits. For one, it’s not 100% moisture-proof. If you’re in a super humid climate—like Florida or parts of Southeast Asia—kraft paper can absorb moisture over time, which will get into the candle and cause that bloom we talked about. We always tell people in those areas to add a small silica gel packet inside the bag if they’re storing candles for more than a few months. It’s a simple fix, but it’s important to mention.
Then there’s the size thing. Candles come in all shapes—tiny tea lights, big pillar candles, even those weird novelty ones shaped like animals. Our kraft bags are versatile, but if you’re storing a giant 3-wick candle that’s 6 inches wide, you need to make sure the bag is sturdy enough. We’ve got heavy-duty kraft bags that hold up to 25 pounds, but if you use a thin, flimsy bag (not from our shop, obviously), it’ll tear, and your candle will be exposed to dust and moisture. Also, don’t cram too many candles into one bag. If they’re rubbing against each other, the wicks can get bent, and the wax might scuff—especially if they’re soft soy wax.
Another mistake people make: closing the bag wrong. A lot of folks just fold the top over once and call it a day, but that leaves gaps for light and dust. We recommend rolling the top of the kraft bag three times and tucking it into the fold, or adding a piece of twine or a sticker to seal it. If you’re using the bag for long-term storage, you can even add a small piece of plastic wrap over the top before folding—just make sure it’s not airtight, so there’s still a little breathability.
Let me also talk about how our customers use these bags, because that’s where you can see the real value. We’ve got a candle brand in Brooklyn that sells “seasonal candle sets”—they put three small candles in a kraft bag with a little card, and they tell their customers to store unlit candles in the bag when they’re not using them. They say their return rate for candle bloom dropped by 40% after they switched from plastic bags to ours. Another customer, a crafter who makes beeswax candles for her Etsy shop, uses our heavy-duty kraft bags for storing inventory in her basement. She said her beeswax candles used to get dusty and faded by the end of the season, but now they look just as good as the day she made them.
But here’s the thing: kraft paper bags aren’t for every storage scenario. If you’re moving candles across the country during a humid summer, a kraft bag is great for protection, but you might want to put that bag inside a plastic tub for extra moisture control. If you’re storing candles in a attic or a garage, where temperatures swing wildly (like 90 degrees in the summer, 30 in the winter), kraft paper alone might not be enough—you’d want a climate-controlled space, which works a lot better with a sturdy bag to keep dust out.
Wait, let’s get a little scientific here, just to back this up. I chatted with a packaging engineer a few years back, and they told me that kraft paper has a water vapor transmission rate (WVTR) that’s perfect for candle storage. WVTR is how much moisture passes through a material. For candles, you don’t want too high (too much moisture gets in) or too low (moisture gets trapped). Kraft paper’s WVTR is around 50-100 g/m² per day, which is right in that sweet spot. Plastic, on the other hand, has a WVTR of less than 1 g/m², which is why it traps moisture. That’s the science behind why the breathable part is so important.
Another point: sustainability. A lot of people ask us why they should use kraft paper instead of plastic, even if it works. Well, kraft paper is biodegradable, recyclable, and made from wood pulp—most of which comes from sustainable forests. Unlike plastic, it doesn’t break down into microplastics that can get into your candle wax or the environment. So if you’re a candle brand trying to be eco-friendly, using our kraft bags for storage makes sense on two levels: it protects your product, and it doesn’t add to the waste problem.
But let’s be real, there are some downsides to kraft paper for candle storage. If your candle leaks (some soy candles are a little soft, especially if they’ve been near heat), kraft paper will absorb the wax stain, which can be annoying if you’re using the bag again. But that’s a small trade-off for the benefits, and honestly, if you’re storing candles, you’re not going to reuse the same bag 10 times anyway—most people use them once for shipping or short-term storage. Also, white kraft paper is less good for light protection, so we always recommend going with the natural brown variety for candles. We make all our candle-focused bags in brown kraft because we know that’s what works best.
So, to circle back to the original question: Are kraft paper bags suitable for storing candles? The answer is yes—for most cases, especially if you’re storing candles short to medium term (up to a year) in normal humidity, our kraft paper bags are perfect. They block light, let moisture escape, don’t react with wax, and are way more sustainable than plastic. But you need to do a few things right: pick a sturdy, heavy-duty bag, seal it properly, add a silica gel packet if you’re in a humid area, and don’t cram too many candles in there.
