Seal Plastic Bags With Aluminium Foil And An Iron

One of the best ways to keep food from spoiling is to seal it in an airtight bag, but you might want to reuse the same bag a food came in instead of putting it in a new Ziploc bag. To do this, reddit user gastropump suggests using an iron to cinch the bag the shut.

It's the same basic premise as a vacuum sealer, and it works great to keep food lasting longer. With your food inside the bag, fold a piece of aluminium foil over the opening of the bag, then run the iron over the foil for a few minutes so the plastic melts together. Wait for it to cool and remove the aluminium foil. Now you have an airtight bag to keep your food from spoiling too quickly.

    I was taught not to melt plastic because it releases poisonous gases. Not sure I want my lunch trapped with poisonous gases. Are ziploc bags recyclable and harmlessly meltable?

      There's a difference between melting and burning, and if you think about it, the bag's already been melted with your food inside because that's how they sealed it in the factory to begin with. So, as long as you don't burn the plastic, should be fine. Or at least not any more harmful than eating things out of factory heat sealed plastic bags...
