Sealable zip-top bags are great for storage, but if you buy plastic bags in bulk you can find yourself stuck with un-sealable bags. A home-centric blog called Re-Nest suggests an easy, green and thrifty way to seal these bags using an old water bottle at home.
All you need to do is cut off the top of the bottle and take off the cap. Push the bag through the bottle neck, fold it over the edges, and twist the cap back on. Please read our step-by-step instructions below.
Cut up a disposable water bottle and keep the neck and top, as pictured in the photo.
Insert the plastic bag through the neck and screw the top to seal.
Test the bag to see if it's air-tight and water-tight. The bag is made to be air-tight (such that water will not leak); the secret lies with the top and screw cap!
Now, your bag has an air and water tight seal - and you didn't have to waste the bottle or the bag. You also no longer have to waste twist ties or rubber bands to seal you bags.
