The key to packing food properly is to make sure it’s in a container where it doesn’t move and shift when you bounce up and down, and that it has a tight-fitting lid. A handful of crackers loosely packed in a hard container will be a handful of dust once you pop it open for lunch. Here’s what works:

  • Sandwiches pack well in plastic lunch containers.
  • Dry things, such as chips, crackers, or nuts, pack well in ziploc bags with the air pushed out.
  • Soup can be put into a short, wide thermos or thermos-like container.
  • If packing leftovers, make sure that your container has a super tight-fitting lid, and that it can be microwaved if you need to heat it up. Stainless steel works pretty well for cold items.
  • If you don’t want to carry a lunch, buy it at work.
