Can’t Finish Snacks? How to Keep Them Fresh Longer

We all enjoy a couple snacks every once in a while. They might actually be some of the best tasting foods especially if you are running short on time and cannot grab a full meal. When you are hungry, ANYTHING will taste amazing and good. Whether you crave savory or sweet snacks, there is always something out there for you.

Sometimes, our eyes can be more “hungry” than our stomachs. As a result, we might purchase a snack that may be more than what we can finish in one sitting. So, you pretty much have leftovers. The longer you do not finish an opened bag of snacks, the more likely it becomes stale and loses that fresh flavor.

What We May Do?

In the past, we may crumble the bag opening to create some sort of folded seal to close the snack bag up. But of course, it would reopen if the snack bag is still quite full. (You are lucky if the bag remained nice and rolled up).

As a result, we changed our tactics. After rolling up the bag opening to the best of our ability, we can use either a clip or rubber band. That seems to work wonders. It does a pretty good job in keeping the snack fresh for some time.

But then something else might have happened. We forget about the snack. While we are restocking our snack stash pile, maybe then we would notice the unfinished snack. As you reopen it again (and hopefully not expired), you might have a couple bites. They taste okay, the flavor is there but it might be kind of stale. Your new snacks are more appealing and it is probably not worth finishing your old snack.

By this point, you are probably wondering if snacks need to be finished quickly after opening. But what if you want to preserve them for a longer period of time? Well, if you want to go above and beyond, you can try using this product.

Tool to Preserve Your Unfinished Snacks Longer

(As an Amazon Associate I earn from qualifying purchases)

You can purchase something like the mini bag sealer device. What this tool does is it helps recreate that seal using heating technology. You will pretty much be getting a brand new bag of snacks.

The tool is a tiny little machine that fits right in the palm of your hand. The dimensions are about 3 inches x 2 inches x 1.5 inches. It comes with a little blade for you to cut the bag (if you happen to destroy it when opening). You can cut the bag to be more straight for easier sealing.

The tool does use 2 AA batteries.


Squeezing the trigger to start preheating is optional. The manufacturers stated that there is no preheating needed but it seems to help me (psychologically at least). Preheating for 3 seconds or so is sufficient.

When heat sealing, make sure to slide the bag sealer device slowly to ensure that the snack bag is shut. This provides ample time for the bag to close.

The manufacturer also says to NOT use the device on:

  • Cling film
  • Cellophane bags
  • Kraft paper bag
  • Pure aluminum bags

Why Avoid Using the Device on Those Materials?

I haven’t personally tested the tool on those materials to see why not, but I can imagine that:

  • The cling film and cellophane bags might melt and create a really hot sticky glue material (like glue guns). This can potentially burn you and damage the device. The glue-like substance might form some barrier around the heating parts of the device and prevent it from functioning properly.
  • The Kraft paper bag has no glue like substance that could form. Try as you might, a seal might never be formed. If you keep trying, the bag might get hot enough to catch on fire.
  • With the pure aluminum bag, it is a pretty good heat conductor. This means that it will retain A LOT of heat and distribute it across the entire bag. This might cause the bag to heat up enough to burn your hand or overheat the bag sealer.

Might be better to listen to the manufacturers for this one.


Snacks are great anytime EXCEPT when you forget about them and it loses the freshness over time. A clip or rubber band can work well if you plan to eat the snack within a short time after opening. If kept longer, the mini bag sealer may be a better option for you.

Good thing some snack bags have a built in zip-lock function nowadays. But if not, you now know some great ways to preserve the life of your snacks! Other than that, please enjoy your snacks!

  1. Its amazing whats available nowadays for storage. especially within the plastic and Tupperware section of the market. These bags are great for keeping all sorts of things nice and fresh. However, Good old glass sealed jars are also good sometimes. However theyre not as robust as plastic and Tupperware is. So these are definitely a winner for me

    • Hello Kwidzin! I agree, it is quite amazing what is available for storage these days. Some ideas are so simple yet innovative and really makes life easier for us. Air tight, old glass jars can also do the trick.

Fortunately, products are always coming out that help us out and this mini bag sealer is one of them.

  4. Hey Mike,

    Very intriguing article on snacks! I myself usually finish every snack I open because I don’t like to waste food. My mom on the other hand, LOVES to save snacks for later. The only downside is that she usually forgets that she tucked the snack away somewhere and it goes bad by the time she remembers to eat it. I will definitely bring this tool up to her as I can definitely see her using it!
