If you’ve ever stood in a grocery store, staring at a stack of paper bags wondering if they’re actually the eco-friendly solution they claim to be, you’re not alone. And if you’re a small business owner, event planner, or anyone in the packaging space, you’ve probably run into the same question: can a paper bag machine actually make biodegradable paper bags? As a supplier of these machines, I get asked this at least a dozen times a week, so let’s break this down straight—no fancy jargon, just the real deal. Paper Bag Machine
First, let’s get one thing out of the way: not all paper bags are created equal, and not all paper bag machines are built to handle biodegradable materials. But yes, a modern, properly adjusted paper bag machine can absolutely produce truly biodegradable paper bags. It’s not some myth or trick—you just have to know what to look for, and I’ve seen it work hundreds of times for different clients.
Let’s start with the basics. A biodegradable paper bag isn’t just a regular paper bag with a fancy label. It needs to break down naturally in the environment, usually within a few months, without releasing harmful chemicals. That means the paper itself has to be made from the right stuff—most often uncoated paper, or paper coated with biodegradable compounds, not plastic. The same goes for the adhesives used to seal the bags, the ink for printing, even the twine or handles. All of that has to biodegrade too.
So how does a paper bag machine tie into this? The machine’s job is to turn raw paper into finished bags, and if it’s compatible with the materials you’re using, it can handle all the steps smoothly. Old, outdated machines—think ones built 10+ years ago—usually aren’t. They’re designed to work with standard, slightly coated paper that’s made for regular grocery or retail bags. But new machines, especially the ones we supply, have adjustable parts that let you tweak settings for different paper types.
Wait, let’s talk about the parts that matter most here. The paper is fed into the machine first, right? If it’s a thick, biodegradable paper (sometimes called “kraft paper” but specifically formulated for eco use), the machine’s rollers have to grip it just right. If the rollers are too tight, they might tear the thin biodegradable paper. If they’re too loose, the paper will wrinkle or misalign, and your bags will come out lopsided. Our machines have variable roller pressure, so you can dial that in for whatever paper stock you’re using. That’s a big one—most clients who have trouble with biodegradable bags are just running their old machine on the same settings they used for regular paper, which doesn’t work.
Next, the sealing part. Paper bags are folded and sealed at the bottom, and sometimes the sides. For biodegradable bags, the seal has to be strong enough to hold groceries or other items, but it also has to be made with a biodegradable adhesive. A lot of cheap paper bag machines use hot melt adhesives that aren’t biodegradable—they might break down over a few years, but they leave behind plastic residue. The good machines have options for both water-based biodegradable adhesives and even heat sealing that works on biodegradable coatings, no glue needed. That’s another key point: if your machine can’t switch between adhesive types, you can’t make truly biodegradable bags.
Then there’s the handles. Most paper bags have either twisted paper handles or flat ones. For biodegradable versions, the handles have to be made from the same eco-friendly material, not plastic. Some older machines only work with plastic handles, but modern ones can feed and twist paper handles without a problem. I’ve had a bakery client who makes bulk bags for their pastries—they switched to one of our machines, adjusted the handle settings, and now their bags compost perfectly in their backyard bin. They used to buy pre-made biodegradable bags, which were more expensive, and now they make their own for half the cost. That’s the proof right there.
But let’s be honest here—there are caveats. You can’t take a regular paper bag machine, throw a roll of biodegradable paper into it, and expect perfect results. First, the paper itself has to meet certain standards. Not all “biodegradable paper” is actually compostable, which is a little different. Biodegradable just means it breaks down over time, while compostable means it breaks down into nutrient-rich soil without any toxins. If you want bags that can go in commercial compost, you need certified compostable paper, and your machine has to handle that. We usually work with clients to test a small sample roll of their paper first, before they buy a machine, to make sure everything lines up. Second, you can’t ignore maintenance. Even the best machine will have issues if you don’t clean the rollers or check the adhesive system regularly. Biodegradable adhesives can dry out faster than regular ones if they’re left in the machine, so a quick clean every other day goes a long way.
I’ve seen a lot of people online say paper bags are worse than plastic, but that’s usually because the bags they’re using aren’t actually biodegradable. If you make them with the right machine and the right materials, paper bags are way better for the planet. And the machine part is doable—you just don’t need to be a big corporation to do it. A lot of small to mid-sized businesses can get a compact machine that makes 100-150 bags a minute, which is enough for their own use or to sell to other local businesses.
Wait, let’s talk about a common misconception I hear all the time: biodegradable paper bags are flimsy, right? But that’s not true if the machine is set up right. Our clients who make takeout bags or grocery bags say their biodegradable bags hold just as much as plastic, and sometimes even more because the paper is thicker. The machine’s ability to fold the bottom correctly is huge here. If the bottom seal is weak, the bag will tear, but with the right adhesive and pressure, it’s not a problem. I had a coffee shop client who switched away from plastic cups and bags, and they told me their customers actually complained less about the paper bags than they did the old thin ones.
Another thing: ink. Even if the paper and adhesive are biodegradable, if you use regular solvent-based ink, that won’t break down. So the machine should also be set up for water-based, soy-based inks. A lot of modern paper bag machines can handle both ink types, but again, it’s a setting thing. We walk every client through how to adjust the ink system if they’re making biodegradable bags, because that’s a detail that trips a lot of people up.
So why do some people think you can’t make biodegradable paper bags with a paper bag machine? It’s mostly because they’re using outdated machines or cutting corners on materials. Back in the day, biodegradable paper was hard to find, and the machines that could handle it were super expensive. Now, both the materials and the machines have gotten way more accessible. We supply machines that are easy to install, easy to adjust, and come with training so you know exactly how to make the switch to eco bags.
Let me give you a quick example of how this works in real life. A couple months ago, a small organic grocery store contacted me. They were buying pre-made biodegradable bags for their produce, but they kept running out, and the shipping costs were high. They had an old machine in their back room that they used to make regular bags, but it was always breaking when they tried biodegradable paper. We sent a technician to look at their machine, made a few adjustments to the rollers and adhesive system, and they tested a sample roll of compostable paper. The first batch came out perfect—no tears, strong seals, even the handles worked. Now they make all their own bags, and they’ve even started selling them to local farmers markets. They saved thousands in the first six months alone.
That’s the kind of result we see all the time. The key takeaway here is: yes, a paper bag machine can make biodegradable paper bags, but only if the machine is modern enough, set up correctly, and paired with the right materials. It’s not a black and white answer, but it’s definitely possible.
Now, if you’re someone who’s looking to get into this, or you already have a machine but you’re tired of struggling with eco bags, don’t overcomplicate it. A lot of suppliers will try to sell you the biggest, fanciest machine, but that’s not always what you need. It’s about finding a machine that’s flexible, has adjustable settings, and supports the materials you want to use.
At the end of the day, making biodegradable paper bags isn’t just a trend—it’s a need. More and more cities are banning single-use plastic bags, so businesses need a way to provide an alternative that’s actually good for the environment. A good paper bag machine lets you do that without breaking the bank.
