Have you ever bought something at the bulk store and found yourself with a bag that you can’t seal? What if you could close a bag with a bottle cap you’ve rescued from the trash? Although I try not to use them often, I do keep plastic bags on hand for things that don’t do well in containers but need to be sealed.
The problem, though, is that I buy our bags at the restaurant supply store, where they’re far less expensive than regular bags, and they don’t zip shut. They also don’t come with twist ties – you have to buy those separately and they come in packages of a zillion. (Only a slight exaggeration)
This method of sealing bags lets me use the bags without buying twist ties (which would just need to get tossed out). It creates a perfect seal and gives easy access to what’s in the bag without damaging it. And when I need to seal something that the children need regular access to, this is much less messy.
All you need to have on hand to close a bag with a bottle cap is an X-ACTO knife and a wide mouthed plastic bottle – one that you’ve rescued from the recycling bin, of course!
Remove the bottle cap.
Remove the neck sleeve of the cap. Don’t throw it out – you’ll need it.
Cut the neck of the bottle just below the thinner plastic part. Be careful – those blades are sharp.
Keep the neck or the mouth of the bottle since this is the usable part.
Insert the plastic bag through the bottom of the neck. Make sure to have an inch allowance at the top of the plastic bag.
Fold the excess plastic from the bag down the threads of the bottle head and seal it using the neck sleeve that we removed in step 3.
You can now fill your plastic bag with your desired food. Or your ten year old son’s collection of acorns.
Screw the bottle cap now to seal the plastic bag.
You now have a perfectly sealed plastic bag ready for storage!
You can use almost any type of plastic bottle, but wide-mouth bottles are perfect for this project. The size of the plastic bag doesn’t matter. As long as you still have a reasonable amount of space on top of it, this will still work flawlessly. This is a perfect all-around sealer that doesn’t even cost a penny.0
