The Right Way to Reseal Chips: Easy Tricks to Keep Them Crunchy Longer

The other day, I reached for a bag of chips at my sister’s place and noticed something… odd. Instead of being sealed shut with a proper clip or twist-tie, the bag was folded over and held together with a pink plastic hair clip – the kind you’d use for a quick bun, not for keeping snacks fresh.

When I asked her about it, she laughed and said, “It does the job just fine.” I didn’t push the issue (this time), but it stuck with me. Could that really be enough to keep chips crunchy? Or is she accidentally signing up for a stale snack surprise?
Let’s explore what really happens when we seal snacks with whatever’s on hand – and what you can try if you want to do it right without going overboard.

1. The Air is Not Your Chip’s Friend

Let’s start with the basics. Once a bag of chips is opened, it’s exposed to air – and with that comes moisture. That’s what makes chips go from crisp and snappy to soft and sad.

Air slowly pulls the crunch out of chips by letting in humidity. Even a small opening can do the trick. A hair clip, while convenient, often leaves little gaps, especially at the corners. Those tiny spaces are enough for moisture to sneak in.
Think of it like this: chips are like sponges for air – they soak up whatever’s around them. So even if the bag feels closed, if it’s not airtight, you’re just inviting sogginess.

2. The Battle of the Clip: Hair Clip vs. Chip Clip

Now, I get it – using a chip clip sounds like one of those “extra” things people do when they’ve bought matching containers and labeled their pantry shelves. But truthfully, chip clips exist for a reason.

They’re flat, firm, and made to squeeze the entire bag shut evenly. Hair clips, on the other hand, are meant to grab hair, not foil-lined plastic. They can be bumpy or loose, especially over time.
Of course, if a hair clip is all you’ve got, it’s better than nothing. But if you’ve ever noticed your chips taste a little off after a day or two, that might be why.

3. Folding the Bag Helps – But Only So Much

Many of us grew up learning the ol’ roll-and-tuck method: fold the top of the chip bag several times, tuck it under, and place it back in the cabinet. It feels neat. It feels finished. But it’s not airtight.

Unless you’re using a rubber band, clip, or zip-top bag, there’s still a good chance air will get in. Folding helps, no doubt – it reduces the surface area that’s open – but it’s not a long-term solution.
You might get away with a few days of decent crunch. But after that? Your chips will likely start to lose their charm.

4. Quick Fixes That Actually Work

Let’s be honest – nobody wants to buy special gear just to eat chips. But keeping snacks fresh doesn’t have to be complicated.
Here are a few easy options you can try that are still pretty low-effort:

  • Binder clips: The kind you find in office drawers. They’re surprisingly strong and often give a better seal than random household clips.
  • Reusable bag clips: These usually cost a couple of dollars and come in multipacks. Worth it if you snack often.
  • Plastic containers: If you’ve already opened the bag, pouring chips into a container with a lid works wonders. The seal is tighter, and it stacks nicely in the pantry.
  • Zip-top bags: These are great for portioning out chips too. Just press the air out and zip.

It’s all about limiting exposure to air – however you do it.

5. Does It Matter for All Snacks?

Not every snack reacts the same way. Some are more forgiving than others. Pretzels and crackers? Still prone to going soft but a little slower. Chips, especially thin ones, tend to be the most delicate.

Snack mixes with coated nuts or baked pieces can stay okay longer, but anything that’s fried or puffed is at higher risk for staleness.
The takeaway? If it crunches now, it’ll likely go stale fast – so sealing matters more than we might think.

6. But Is It That Big of a Deal?

Here’s the thing: it’s okay if you don’t always use the “right” clip. Life gets busy, and most of us grab whatever’s nearby. If your chips go a little soft, it’s not the end of the world.

But if you’re someone who loves a good crunch – or hates wasting snacks that don’t taste quite right – taking five seconds to seal things properly is worth it.
And if you’re living with someone who insists their hair clip does the trick? Maybe don’t argue. Just quietly stash a few better clips in the kitchen drawer and see what happens.

7. It’s Not Just About Freshness – It’s About Mindset

Okay, maybe that sounds dramatic. But hear me out: when we take a second to close a bag the right way, it’s a tiny act of care. For our food, our future selves, and our shared spaces.

It’s the same mindset that shows up when we wipe down counters or put leftovers in containers instead of letting them dry out in the fridge. It’s not about being perfect – it’s about making small things just a little better.

Conclusion: Go Ahead and Use the Hair Clip… But Maybe Have a Backup

So, does a hair clip really work for sealing chips? Kind of. Sometimes. But it’s not the best choice if you’re serious about keeping things fresh.

If you’ve got better clips, use them. If not, do the best you can. No judgment here. And hey – maybe the next time you’re organizing your snacks, you’ll find a small win in choosing the clip that actually locks in the crunch.
Because a bag of chips that still crackles when you open it? That’s a little joy worth saving.
