When I started in the used packaging machinery game, I’ll admit I skipped a few key checks on my first bulk purchase of old filling lines. Ended up with a machine that ate seals like candy and broke down every other shift—cost me my first big client, and taught me a lesson I still drill into every customer I chat with now. If you’re in the market for used packaging gear, I get it; new machines cost a small fortune, and used ones feel like a steal… but only if you avoid the same dumb mistakes I made. Here’s the real, no-BS checklist I walk everyone through, no fancy sales fluff. Used Packaging Machinery
First up, the actual “physical condition” of the machine—don’t just take the seller’s word that it “only ran 10k hours.” I once saw a guy say his labeler had 8k hours, but the motor’s paint was chipped so bad you could see rust, and the gearbox was leaking oil like a sieve. Always ask for maintenance logs first—if a seller can’t pull up regular oil changes, belt replacements, or part swaps, that’s a red flag. If it’s been sitting in a warehouse for months, check for rust on moving parts (rocker arms, conveyor rollers, gear teeth) and make sure the chain or belts aren’t stretched to the point of snapping. Even small rust spots can turn into big problems fast—corrosion eats at metal and throws alignment off, which ruins packaging jobs. Don’t forget to check the control panel either; cracked screens, loose wires, or buttons that stick are easy to fix but add up fast, and if the PLC (the brain of the machine) has weird error codes, ask the seller what they mean. A lot of times it’s a quick reset, but sometimes it’s a sign of a dying component.
Next, compatibility—this is the one I see people mess up the most. Just because a machine was made to run bottle sizes doesn’t mean it’ll fit your stuff. Let’s say you need a shrink wrapper for 16oz soda cans—if the machine’s former setup was for 2-liter bottles, the conveyor width, guide rails, and even the seal bar length might be totally wrong. Ask for photos of the machine running actual product, not just generic test runs, and if possible, get the specs for changeover parts. Changeover parts are the bits that let you switch between product sizes—they’re usually cheap, but if the seller lost them, you might pay hundreds to source replacements custom. Also, check the power and air requirements. Older machines might run on 220V single-phase, but your facility is 480V three-phase, or they need 100psi of compressed air and you only have 80psi. That’s not a “minor adjustment”—that might mean rewiring your whole plant or buying a new air compressor, which eats into any “steal” deal you thought you were getting. And if you run different packaging materials—like rigid containers vs flexible pouches—confirm the machine can handle both. I once had a customer buy a used filling machine that only worked for rigid jars; they needed it for stand-up pouches, and the feed system wasn’t even built to handle flexible film.
Then there’s actual functionality—don’t just look at it, run it if you can. If the seller is local, ask to do a test run with your product (or a close match) on their floor. Even a 10-minute test will tell you way more than any description. Watch for jams—does the product get stuck in the feed chute? Is the seal bar on a wrapper melting too much or not sealing tight enough? Does the labeling machine skew labels even on flat surfaces? If it’s a remote sale, ask for a live video walkthrough and test of the main functions—watch the motor speed, the conveyor’s movement, the seal cycle. Also, pay attention to noise and vibration; a machine that’s grinding or shaking way more than it should is probably out of alignment or has worn bearings that’ll fail soon. If the seller won’t let you test it, that’s a hard pass—no exceptions. I’ve turned down dozens of sales from sellers who hide a broken part behind a fancy photo.
Parts availability and service—this is the part that kills used machines. If a machine was made in the 80s, does the manufacturer even make parts for it anymore? A lot of older packaging gear is now obsolete, and the only way to get parts is to hunt for used ones at a junk yard or pay a premium for custom machining. That’s fine if the machine is super simple, but if it’s a high-speed filler with a fancy PLC, you need to know if you can get parts quickly. Also, ask about service support—does the seller (or someone) know how to fix this model? Are there local techs who work on these machines, or will you be waiting 3 days for a specialist to fly in, and that’s downtime you can’t afford? I keep a big stock of common parts for all the machines I sell—belts, seals, sensors, small PLC modules—so my customers don’t have to wait weeks for a part to fix a jam. If the seller can’t offer that, ask where you can source parts for this specific model, and factor that cost into your total price.
Hours and usage history—don’t just take the number of hours at face value. A machine that ran 24/7 for 5 years is way more worn than one that ran 8 hours a day, 5 days a week for 10 years. Ask what kind of product it ran—something corrosive like citrus juice or battery acid will eat at metal parts way faster than a food-grade product like cereal boxes. I once sold a labeler that ran 24/7 on cleaning chemicals; the motor was shot within a month, even though the hour count was low. Also, ask why the seller is getting rid of it. If it’s because they upgraded to a newer model, that’s fine. If it’s because it breaks down constantly and they can’t fix it, that’s a huge red flag. A lot of sellers will lie and say they upgraded to a bigger machine, so check reviews if it’s a known brand—search that machine model + “breakdown” or “issues” and see what comes up.
Price and extra costs—here’s the math no one tells you. The upfront price is only part of it. Factor in shipping, installation, any needed repairs or parts, utilities (power/air), and future maintenance. A $5k used wrapper might seem cheap, but if it needs $3k in parts and $2k in installation, that’s $10k total—way more than a slightly nicer used one that needs nothing. Also, negotiate, but be realistic. I don’t lowball customers, but if a machine has obvious wear, point it out. If the seller won’t budge, walk away—there’s always another machine. And never pay the full amount upfront. I ask for a deposit, then the rest when the machine is tested and ready to ship. That way, the seller doesn’t ghost you with a broken machine.
Don’t forget the small stuff that trips you up later. Check the footprint and weight—can it fit through your door, down the hall, into your production area? I had a customer buy a big case sealer that was too wide to get through their loading dock door; they had to remove a chunk of wall, which cost way more than they saved on the machine. Also, check if it has any extra features you might need—like a coder for expiration dates, or a reject mechanism for bad seals. Those might be add-ons you have to pay extra for, or they might not exist on the machine at all.
Look, I’m in this for the long haul. I sell used packaging machinery because it’s a great option for small businesses that don’t have the budget for new gear, but only if it’s reliable. I’ve fixed enough broken machines and lost enough customers to know that skipping these checks only leads to headaches. If you’re ready to stop stressing about used packaging gear and get a machine that works for your business, hit me up. We can talk through your exact needs, walk through machines, and make sure you don’t end up with the lemon I bought on my first day. Don’t overcomplicate it—just ask the right questions, test the machine, and factor in the hidden costs. That’s how you get a deal that lasts, not a money pit.
