Hey everyone, this is Jake from Protective Shipping Supplies, and I get it—when you sell stuff that’s supposed to keep people’s packages safe (like bubble wrap, foam inserts, air pillows, and corrugated corner protectors), the last thing you want is to send out inventory that’s all beat up before it even leaves your warehouse. I’ve seen it happen way too many times: a client stores their new bulk bubble roll in a damp corner, and by the time they pull it out to ship, it’s sticky, stretched, and totally useless. Or air pillows that get squished and can’t fluff back up because they’re stuffed in a cramped, warm closet. Protective Shipping Supplies
Today, I’m breaking down exactly how to store our protective shipping supplies (and really, any shipping supplies) so they stay in tip-top shape for months—no more wasted inventory, no more last-minute panics when you need to grab something fast. Let’s dive in, since I’ve learned this stuff through years of dealing with supply chain hiccups and helping customers fix their storage messes.
First, let’s talk about the biggest enemy of all: moisture. Most of our protective supplies are made from plastics, foams, or corrugated cardboard—materials that hate being damp. I once had a small e-commerce client who stored 50 rolls of bubble wrap in a basement (don’t do this, by the way) after a leaky pipe went unnoticed for two weeks. By the time they called me, the bubble wrap was so waterlogged it felt like flimsy plastic bags, not the sturdy stuff we stock. The air pillows we sell? They’re made from thin, air-filled plastic that can absorb tiny amounts of moisture, which makes them sticky and impossible to inflate properly when you need them. Corrugated corner protectors are even worse—they’ll crumple and lose their rigid structure if they get wet, which defeats the whole point of using them to keep boxes from getting dented.
So what’s the fix for moisture? Find a storage spot that’s not in a basement, not in a garage that gets rained on, and not right next to a dishwasher, sink, or any other water source. We tell all our clients to aim for a space where the humidity is between 40% and 50%—that’s the sweet spot for keeping plastics and foams flexible and cardboard strong. If you don’t have a hygrometer to check humidity (a cheap little tool that measures moisture in the air, by the way), just use your best judgment: if the space feels clammy or you see condensation on metal tools in there, it’s too damp.
Next up, temperature. We all know plastic gets weird when it’s too hot or too cold. Extreme heat makes bubble wrap stretch out and lose its spring—those little air bubbles will deflate over time, so when you wrap a package, it won’t absorb impacts like it’s supposed to. We once sent a batch of foam inserts to a client who stored them in a shipping container out in the desert for three months. By the time they used them, the foam was so soft it didn’t have any cushion left—total waste of money. On the flip side, extreme cold makes plastic brittle. If air pillows are stored in a cold trailer overnight before they’re put away, they’ll crack when you try to inflate them, which is a huge headache when you’re in a rush to ship orders.
The ideal temperature range for our supplies is between 60°F and 75°F (that’s around 15°C to 24°C, for my international peeps). If your warehouse or storage area gets way hotter than that, try to move stock farther from loading docks or roofs that get direct sun. If it’s super cold, invest in a small space heater for the storage zone—nothing fancy, just enough to keep the temp from dropping below 50°F. I’ve had clients tell me they use old office space heaters that cost like $20, and it’s made a huge difference in keeping their supplies usable.
Now, how you actually stack and organize your supplies matters way more than you might think. Let’s start with the big stuff first: rolls of bubble wrap, foam rolls, and long sheets of corrugated. If you just stack them flat on the floor, they’ll get squished, especially if you put heavy boxes on top of them. We recommend hanging roll supplies on sturdy metal racks or using vertical roll holders—you can find these pretty cheap online, or even build them if you’re handy. This keeps the rolls round, so when you go to unroll them, they don’t kink or stretch unevenly.
For smaller items—air pillow cases, foam inserts, corner protectors, packing peanuts—don’t just stuff them in random boxes or bins. Use clear plastic bins with tight-fitting lids, not cardboard boxes. Cardboard gets dusty, damp, and attracts bugs (gross, I know) if it’s left open or in a humid space. Clear bins let you see what’s inside without opening every one, which saves time when you’re grabbing supplies for an order. Label each bin clearly too—like “Large Air Pillows” or “Small Foam Inserts for 6×6 Boxes”—no more digging through 10 bins to find what you need.
Wait, what about hanging bags? If you buy bulk air pillows that come in big hanging bags, keep them hanging if you can. Don’t yank them off the hanger and stuff them in a box, because that’ll twist the opening and make it hard to pull out pillows without tearing. I’ve seen clients do that, and they end up with half a bag of ruined pillows.
Another big no-no: overcrowding storage spaces. If you pack every inch of your warehouse aisle with supplies, you can’t get air circulating around them. Stagnant air makes humidity higher, which brings back that moisture problem we talked about earlier. Leave a little space between stacks of bins or rolls, and make sure you can walk through the space easily so you’re not knocking things over and damaging them.
What about dust? You might not think dust is a big deal, but it is for packaging supplies. If you’re wrapping a fragile item like glassware with dusty bubble wrap, that dust can get on the glass and leave marks, which makes customers unhappy. Plus, dust can clog the inflator machines we sell (wait, yeah, we have those too for air pillows) if you’re using dusty plastic parts. So how do you keep dust away? Those same clear plastic bins with lids work wonders—they keep dust out way better than open bins. If you have roll supplies, you can buy plastic wrap to cover the ends of the rolls when they’re not in use, or use dust covers for the racks.
Oh, and don’t forget about expiration dates—yes, even protective shipping supplies have them, though most of ours last a year or two if stored right. Plastic products (bubble wrap, air pillows) can break down over time, especially if exposed to sunlight. Wait a second—speaking of sunlight! That’s another big one I almost missed. Never store your supplies in direct sunlight. UV rays make plastic fade, get brittle, and crack. I had a client once who stored a pallet of bubble wrap by a loading dock that got direct sun all afternoon. A month later, half the rolls were so brittle they crumbled when you touched them. So keep supplies in a shaded area, or use opaque plastic bins if you have to store them somewhere that gets some light.
Let’s also talk about first-in, first-out (FIFO) inventory. This is super important for any business, and it applies to our supplies too. When you get a new shipment of bubble wrap or air pillows, don’t put the new stuff in front of the old stuff. Put the new stuff at the back, so you use the older stock first. That way, you’re not left with a bunch of expired, ruined supplies because you used the newest ones first. I’ve seen so many small business owners make this mistake, and it ends up costing them hundreds of dollars in wasted inventory. Pro tip: mark the date you received each shipment on the bin or roll, so you can easily tell what’s older.
Wait, what if you have limited storage space? Like, if you’re a small e-commerce seller with a closet instead of a whole warehouse? I get that—we work with tons of solopreneurs who don’t have big spaces. For you, focus on the key stuff: keep moisture and sunlight out first. Use under-bed storage bins if you need to, just make sure the area under your bed isn’t damp (if you live in a humid climate, maybe skip under-bed). Hang small rolls of bubble wrap on a tension rod in your closet—tension rods are cheap and don’t require drilling, perfect for renters. For air pillows, use a small, clear plastic bin that fits under your desk, so it’s out of the way but easy to grab. Don’t overbuy, either. I know it’s tempting to stock up to save money, but if you can only use 10 rolls a month, don’t buy 50—you’ll end up with a bunch of supplies that go bad before you use them.
Let me also throw in some common mistakes I see all the time, just to save you the hassle. First, don’t store heavy items on top of your protective shipping supplies. Like, if you have a pallet of boxes full of other products, don’t put it on top of a pallet of bubble wrap—you’ll squish the rolls and ruin them. Second, don’t use plastic bags to store supplies unless they’re sealed, but even then, make sure there’s no moisture inside the bag. Some cheap plastic bags can trap humidity, which is the opposite of what you want. Third, if you’re storing supplies long-term (like more than 6 months), make sure you check on them every few weeks. I had a client who stored a pallet of foam inserts for a year and forgot about them—when they checked, mice had gotten into the cardboard boxes and chewed half the foam. Gross, but avoidable if you just do a quick check every month or so.
At the end of the day, storing protective shipping supplies correctly isn’t rocket science—it’s just about paying attention to the environment, how you organize things, and not skipping the small stuff like FIFO. If you follow these tips, you’ll cut down on wasted inventory, have supplies ready to go when you need them, and even save money long-term.
