If you\u2019re an artist\u2014whether you\u2019re a hobbyist who paints on weekends or a full-time illustrator juggling a dozen mediums\u2014you\u2019ve definitely stared at a closet full of art supplies and thought: where do I even put all this? Tubes of acrylic paint that dry out after half a use, watercolor pans that get dusty, long paintbrushes with frayed bristles, those weirdly shaped sketchbooks that won\u2019t fit on a shelf. I\u2019ve been there too, and as someone who runs a vacuum bag supply company, I get asked all the time: can these tight, air-tight bags actually work for storing art supplies? The short answer? Yes\u2014but only if you do it right. Let\u2019s break this down without all the jargon, no stuffy lab talk, just real stuff I\u2019ve learned from working with both artists and people who test our bags every day. Vacuum Bag<\/a><\/p>\n

<\/p>\n

First, let\u2019s talk about why art supplies go bad in the first place, because that\u2019s the root of the problem. Most art materials hate three things: excess moisture, oxygen, and dust. Let\u2019s take acrylic paint, for example. You crack a tube open, squeeze out some paint, and if you leave the cap off for even an hour, a thin skin forms on top. That skin is just dried paint where oxygen hit it\u2014same as how an apple browns. Watercolor is even worse; those solid pans are prone to mold if there\u2019s any humidity in the air, especially if you live somewhere with a lot of rain, like the Pacific Northwest or parts of the UK. Even things like charcoal sticks can absorb moisture from the air, which makes them crumble mid-drawing way faster.<\/p>\n

Vacuum bags are all about removing oxygen and sealing out moisture, right? So on paper, that\u2019s exactly what art supplies need. But here\u2019s the catch: not all art supplies are the same, and not all vacuum bags are made equal. A lot of people grab a random food vacuum bag from the grocery store and try to stuff their paintbrushes in, and that\u2019s where things can go wrong. For one, food bags are usually thinner, so if you have a metal ruler or a sharp pencil, they\u2019ll puncture super easy. For two, some cheap vacuum bags have tiny pinholes you can\u2019t even see, which means oxygen and moisture will still get in, defeating the whole purpose. That\u2019s why as a supplier, we make bags that are thick enough to handle sharp edges but still flexible enough to wrap around weirdly shaped sketchbooks.<\/p>\n

Let\u2019s run through some common art supplies and how well vacuum bags work for each, because that\u2019s the stuff that actually matters for you. Acrylic paints first\u2014these are probably the most high-maintenance liquid supplies. I have a friend who\u2019s a muralist; she used to throw away half a tube of paint every month because it dried out before she could finish it. Now she puts each tube in a vacuum bag, sucks out the air, and when she needs to use it, the paint inside is just as soft as the day she bought it. Wait, but hold on\u2014don\u2019t vacuum paint too hard. If you squeeze the tube until it\u2019s flat as a pancake, you\u2019re going to force paint out of the cap and make a mess inside the bag. You just want to remove the air around the tube, not the paint itself. Same with watercolor pans: those solid blocks don\u2019t have liquid inside, so vacuuming them is totally safe. I\u2019ve seen artists put a whole set of pans in one bag, add a little silica gel packet (more on that in a sec), and they\u2019ve stayed mold-free for over a year now.<\/p>\n

Then there\u2019s dry supplies: charcoal, pastels, graphite sticks, even those giant rolls of paper. Charcoal is super porous, so if it absorbs moisture, it won\u2019t make dark, clean lines anymore. Vacuum bags keep that moisture out, so your charcoal stays as powdery as the day you bought it. Pastels are a little trickier\u2014some soft pastels crumble if you apply too much pressure, but if you just seal them in a vacuum bag without over-sucking, they\u2019re fine. We had an artist test our bags for pastels and said her sticks didn\u2019t crumble once in three months of storage, which was a huge win for her, since she used to lose half her stash to breakage. Sketchbooks are another big one. If you have a hardcover sketchbook that you\u2019re not using right away, putting it in a vacuum bag will keep it free of dust and prevent the cover from fading. Just make sure to leave a little air in around the pages\u2014if you vacuum too hard, the pages might stick together, especially if there\u2019s any humidity.<\/p>\n

Now, let\u2019s talk about the mistakes people make when using vacuum bags for art supplies, because those are the things that can actually ruin your stuff. First, forgetting to add silica gel packets. Even if you vacuum out all the air, there\u2019s still tiny bits of moisture in the bag from the supplies themselves\u2014paint tubes have a little residual moisture, sketchbooks hold a bit, etc. Silica gel absorbs that leftover moisture, so it\u2019s a must for anything that\u2019s prone to mold. You can buy these super cheap online, just toss one in each bag before sealing it. Second, over-vacuuming. I can\u2019t stress this enough. For liquid supplies like paint, you just need to remove the air around the tube\u2014if it\u2019s completely flat, you\u2019re going to have issues. For dry supplies, a gentle vacuum is fine, but if you squeeze the bag so hard that it\u2019s tight enough to bounce, you might break something. Third, not cleaning the supplies before you put them in. If you have a paintbrush with caked-on acrylic, or a charcoal stick that\u2019s got dust all over it, putting it in a vacuum bag will trap that gunk there, and it\u2019ll be way harder to clean later. Give your supplies a quick wipe with a damp cloth (for brushes) or a dry brush (for charcoal) before sealing them up. Fourth, using the wrong size bag. If you try to stuff a 12×16 inch sketchbook into a small food bag, it\u2019s going to rip, and you\u2019ll lose all the benefits. Invest in different sizes\u2014we have small bags for paint tubes, medium for sets of brushes, large for sketchbooks and paper rolls.<\/p>\n

Wait, what about things you shouldn\u2019t put in vacuum bags? There are a few art supplies that actually don\u2019t work with them, and it\u2019s good to know these so you don\u2019t waste time. First, oil paints. Wait, why? Oil paint is a bit tricky because it dries through oxidation, but if you remove all the oxygen, it won\u2019t dry at all. But if you\u2019re storing tubes of oil paint for long-term (like if you have a tube you\u2019re not going to use for six months), a vacuum bag is fine\u2014you just have to make sure you don\u2019t open it until you\u2019re ready to use it, because once you break the seal, it\u2019ll start drying. Second, water-based markers. Those have liquid inside, and if you vacuum the bag too hard, you can force the ink out of the marker\u2019s tip, making a mess. Third, loose paint chips or leftover scraps. These are tiny, and they\u2019ll get sucked into the seal of the bag, which can ruin the bag\u2019s ability to airtight over time. If you have small scraps, put them in a small container first, then put the container in the vacuum bag.<\/p>\n

Now, let\u2019s get into why this works better than other storage options, because that\u2019s a big question. A lot of artists use plastic bins, right? But plastic bins aren\u2019t airtight\u2014even the ones with lids have tiny gaps where air and moisture can get in. Dust also gets in, no matter how tight the lid is. Vacuum bags are completely airtight, so nothing can get in or out. And they\u2019re way more space-efficient. If you have a closet full of supplies, vacuum bags can shrink your stash down by 50% or more. I helped a local painter organize her studio last year, and she went from three shelves of supplies to one big bin full of vacuum-sealed bags. That\u2019s a game-changer for anyone with a small space.<\/p>\n

We\u2019ve actually had a ton of artists test our bags, and the feedback has been insane. One watercolor artist in Portland told us she used to lose a whole set of pans to mold every winter, and after using our bags with silica gel, she hasn\u2019t had a mold issue in two years. A muralist in Chicago said she saves over $100 a month now because she doesn\u2019t have to throw away half-dried paint tubes. Those are the stories that make this job worth it, because we\u2019re not just selling vacuum bags\u2014we\u2019re helping artists save money and keep their supplies in good shape longer.<\/p>\n

Now, if you\u2019re thinking about trying this, let\u2019s make it easy for you. Don\u2019t go out and buy random food bags\u2014they\u2019re thin, they don\u2019t last, and they\u2019re not designed for sharp art supplies. Look for bags that are thick (around 3 mils is good), have a strong seal, and are puncture-resistant. We make all of our bags specifically for storing art supplies, so they\u2019re thick enough to handle paintbrushes, metal rulers, and sharp pencils without ripping, and they have a double seal that stays airtight, even after multiple uses. Also, make sure you\u2019re using a good vacuum sealer\u2014wait, do you need a fancy one? No, a basic home vacuum sealer works fine, but if you don\u2019t have one, some of our bags are compatible with hand pumps, which is perfect if you\u2019re just storing a few small items.<\/p>\n

A quick pro tip from our team: label every bag. If you toss a bunch of paint tubes in a bag, you\u2019ll forget which color is in there after a few months. Write on the bag with a permanent marker, or use a label sticker. Also, store the bags in a cool, dry place\u2014don\u2019t leave them in a hot attic or a damp basement, because even vacuum bags can hold up less well in extreme temperatures.<\/p>\n

Wait, let\u2019s address a common myth: some people think vacuum bags will make paint go bad faster, but that\u2019s not true. Paint dries when oxygen reacts with it, so removing oxygen actually slows down the drying process. We\u2019ve tested paint tubes sealed in vacuum bags for over two years, and when we opened them, the paint was still just as workable as the day it was sealed. That\u2019s way better than leaving a tube in a drawer with the cap loosely on, which would dry out in a few weeks.<\/p>\n

Another thing: what about paper? If you have large rolls of drawing paper, putting them in a vacuum bag will keep them free of dust and prevent them from warping. We\u2019ve had artists store giant rolls of watercolor paper in our vacuum bags for over a year, and when they unrolled them, they were completely flat, no warping at all. That\u2019s way better than storing paper in a cardboard box, which can get damp from the air and warp over time.<\/p>\n

Now, if you\u2019re ready to give this a shot, or if you\u2019re a studio manager looking to organize a whole team\u2019s supplies, we can help. We have bulk options for anyone who needs more than a few bags, and we can even customize bags for specific supplies if you have unique needs. No matter if you\u2019re a hobbyist with a small stash or a professional with a studio full of supplies, we\u2019ve got the bags to fit. If you\u2019re curious about pricing, shipping, or just want to ask a question about the best way to store your specific art supplies, reach out to us to talk more\u2014we\u2019re always happy to help.<\/p>\n
