How to Create a Permanent Seal in a Plastic Bag

For whatever reason, you've decided you would like to store something in a plastic bag and don't want air to get in. Maybe you don't trust the seal on a resealable bag or want to store something in a plastic bag that lacks a resealable strip. There's a way to permanently seal a plastic bag, barring a deliberate attempt to open. It's a great solution for food items you want to store securely or give as gifts, and it's an economical way to store and organize buttons, beads or other small objects.
