Hey everyone, it’s Jake here—from that small, no-fuss paper bag supplier you’ve probably seen popping up at local markets and small business shops lately. Today I’m diving into a question I get all the time, almost every week from customers who bring in boxes of dusty old books, or independent bookstore owners restocking shelves and wondering what to grab for temporary or long-term storage: Can paper bags be used for storing books? Paper Bag
Full transparency, when I first started getting this question two years back, I had zero clue. I thought paper bags were just for hauling groceries, not for protecting fragile, important stuff like books. But over time, I’ve tested this, talked to a bunch of book lovers and even a few local library volunteers, and done my own deep dive into the science of paper and how it interacts with paper, ink, and that weird, old book smell we all know. So let’s break this down real, no-BS style, no fancy jargon, just what works and what doesn’t when it comes to putting books in paper bags.
First off, let’s get the basics straight: not all paper bags are made equal. That’s a huge mistake people make when grabbing a random bag from the back of their pantry. The cheap, thin grocery store produce bags? Definitely skip those. They’re only good for holding a head of lettuce, not a $50 first edition of To Kill a Mockingbird. The paper bags I sell—our standard 100% recycled, thick (100gsm to 120gsm) kraft bags? Those are game-changers. Here’s why the thickness and quality matter so much, from what I’ve learned.
Books are fragile for two main reasons: their paper pages and their covers (whether hardcover or paperback) absorb moisture like crazy. Humidity is the enemy here. If you store a book in a thin, flimsy bag and it gets damp—like if it’s in a basement that leaks a little, or a garage where it rains in through a crack—the thin bag won’t do anything to slow that moisture down. Moisture leads to mold, warped pages, that weird musty smell that takes forever to get rid of, and even rust if there’s any metal on the book (like staples in old paperback spines). Thick kraft paper, on the other hand, acts as a buffer. It’s breathable, wait—hold on, that’s a key point I almost messed up. A lot of people think paper bags trap moisture, but that’s only if they’re cheap or if you seal them all the way. Our bags are designed to have tiny, natural pores in the kraft paper, right? Because paper is made from wood pulp, which has those tiny gaps that let air circulate. So if you don’t cram a book in and seal it super tight, the bag lets excess moisture escape, instead of trapping it like plastic would. Plastic bins or plastic bags are actually way worse for long-term book storage because they hold all that moisture in, leading to way more mold and rot. That’s a big win for paper bags.
Then there’s the issue of ink transfer. Wait, when you have books—especially old ones, or even new ones with printed covers—does the paper bag rub off onto the book? I tested this a few months back, just to be sure. I took a stack of 10 paperbacks I hadn’t read yet, all with glossy covers, and put them in our standard kraft bags, tucked away in my attic for three months. When I pulled them out, no ink smudges, no transfer, nothing. Why? Because our kraft paper is untreated—no extra coatings, no plastic liners, no weird chemicals added to make it shiny or water-resistant (we offer a water-resistant coating as an add-on, by the way, but even the regular stuff is fine for ink). I also tested a thin, uncoated bag from a local fast food place, and after a month, a few of the paperbacks had faint gray smudges on their spines. That’s because the thin bag was so abrasive against the glossy cover. Our thicker kraft bag has a smoother, denser surface, so it doesn’t rub as hard. So if you’re using good quality paper bags, ink transfer is basically non-existent.
Now, let’s talk about what paper bags are good for, and what they’re not so good for. First, the positives: Temporary storage is where paper bags shine. If you’re moving, and you have 20 or 30 books you don’t want to toss in a box (wait, actually, boxes work too, but bags are easier to carry, and you can label them clearly), paper bags are perfect. I helped a friend move last year, and she had a whole shelf of vintage paperbacks. We used our medium kraft bags, labeled each “Fiction, Vintage” and she could carry a bag in one hand, instead of wrestling with a heavy box. They’re also great for short-term storage—like if you’re putting books in a closet for a few months while you redecorate, or if you’re a bookstore owner storing extra inventory off-site. Another big plus: they’re way more eco-friendly than plastic, which is a huge deal for book lovers who care about the planet. Paper breaks down in compost in like 3 months, vs plastic which takes hundreds of years. No brainer there.
What about long-term storage? This is where I want to be honest, because I don’t want to sell you something that’s only good for a month. If we’re talking years, like storing books in an attic or basement for 5+ years, paper bags work but they’re not the best. Why? Because over time, even the thickest kraft paper can get brittle if it’s exposed to fluctuating temperatures. Attics get super hot in summer, cold in winter, that cycle makes paper break down. Also, paper can attract pests—like silverfish, which love to eat paper and book pages. That’s the big downside of paper vs, say, acid-free plastic boxes. Wait, but acid-free paper bags? We actually offer those for customers who need long-term storage, they’re a little more expensive, but they’re treated to resist brittleness and don’t have any acids that could leach onto your book pages over time. That’s a game-changer for collectors who want to keep first editions for 20+ years. So if you’re storing long-term, go for acid-free kraft paper bags, not regular ones.
Another thing people ask me: Can you reuse paper bags for storing books? Absolutely. If you use a book in a paper bag, take the bag out, fold it neatly, and store it somewhere dry, it can be reused 3 or 4 times. Just don’t reuse a bag that had greasy food in it—grease can seep into the paper and then into your book pages, leaving stains that won’t come out. That’s a rule I learned the hard way, when I tried to reuse a taco bag for a book and got a grease stain on a 1980s copy of The Outsiders. Oops, never again.
Wait, let’s address a common myth: people think paper bags will scratch book covers. I mentioned the thin fast food bag earlier, that was scratching. But when you use our thick, smooth kraft bags, no scratching at all. I tested this with a hardcover copy of Harry Potter and the Sorcerer’s Stone—put it in a bag, moved it around, dropped it a few times (don’t judge, I was testing!), and the cover was totally fine. The bag’s thick enough to cushion small bumps, too, which is great for moving.
Now, what are the best practices if you’re actually going to use paper bags for storing books? Let’s make this actionable, not just random stuff I’ve picked up. First, pick the right bag size. Don’t cram a 1000-page hardcover into a small bag—you’ll tear the bag, and you’ll bend the book’s spine. We have sizes ranging from small (perfect for paperbacks) to extra large (great for hardcovers and oversized coffee table books). Measure your books first, or if you’re buying from us, just shoot a note and we’ll help you pick the right size. Second, don’t seal the bag all the way. Leave the top open a little, or fold it loosely over the top, not taped shut. That lets air circulate, prevents moisture buildup. If you’re storing in a super humid area, you can add a few silica gel packs (the ones that come in shoe boxes) to the bottom of the bag to absorb extra moisture, that works great. Third, label everything. Write what’s in the bag on the outside with a permanent marker—way easier than digging through 10 bags to find that one cookbook you want. Fourth, store the bags on a shelf, not on the floor. Even if your floor is dry, a leak could happen, or water could seep up from the ground. Shelves are safer.
I also talked to Maria, who runs the local independent bookstore here in town—Maple Street Books. She told me she’s been using our paper bags for her inventory storage for a year now, and it’s cut down on her plastic waste by 70% because she used to use plastic bags for extra books. She says the only time she has an issue is if she puts a bag in the basement for a few months and forgets to check it, sometimes she gets a little mildew on the very bottom if the floor gets damp, but that’s easy to fix by wiping the book and moving it to a dry shelf. No major issues, and her books are in way better shape than when she used plastic.
Another test I did: I put two identical paperbacks, same age, same condition, in two different bags—one our kraft paper, one a cheap generic grocery bag. I left them in my laundry room (which has a little humidity from the washing machine) for 2 months. The generic bag’s book had a faint musty smell when I opened it, the kraft bag’s book smelled like it did when I put it in. That’s the difference thickness makes. Generic bags are too thin to block that extra humidity from the air, kraft is thick enough to create that buffer.
Wait, what about acid content? That’s a big one for book collectors, because old paper (and even some modern paper) has acid that breaks down over time, leading to yellowed pages. Our regular kraft paper is acid-free, right? We make sure of that. But if you have super valuable, rare books—like first editions signed by authors, that are worth hundreds or thousands of dollars—you might want to go for the acid-free archival paper bags we offer. Those are made specifically for storing paper items that need extra protection, so they won’t leach any acid onto your book pages even after years. That’s an extra cost, but for the value of a rare book, it’s worth it.
I know some people are still worried about pests. Like, do paper bags attract bookworms or silverfish? I haven’t had that problem, and Maria at the bookstore hasn’t either. The key is to keep the bags in a dry area. If your space is humid enough to attract pests, then any storage method is at risk—plastic, boxes, bags, whatever. As long as you’re storing in a dry, moderately cool place, paper bags are fine. If you’re in a super humid area, add those silica gel packs, that helps a ton.
Let’s wrap this up with the real answer to the original question: Yes, paper bags can absolutely be used for storing books, as long as you pick the right type of paper bag, follow a few simple rules, and be realistic about short-term vs long-term storage. Our thick, 100% recycled kraft paper bags are perfect for temporary storage, moving, short-term closet or shelf storage, and even medium-term (1-3 years) storage. For long-term (5+ years) storage of rare or valuable books, our archival acid-free kraft bags are the way to go, they give you the extra protection you need without using plastic.
Now, if you’re someone who needs bags for personal use—moving your book collection, storing extra books at home, whatever—we’ve got you covered with small, medium, and large sizes at affordable prices. If you’re a bookstore owner, library volunteer, or anyone who needs bulk bags for inventory storage, we offer bulk discounts too, and can customize with your logo if you need that.
I get that a lot of people still default to plastic bins, and I totally get why—they feel sturdy. But plastic traps moisture, and it’s terrible for the planet. Paper bags are just as sturdy, way more eco-friendly, and work really well for books as long as you use the right kind. I’ve tested this for two years, I’ve seen Maria use them for a year, and I’ve heard from other customers who use them for their vintage book collections, and everyone’s happy with the results.
