Pack them in a box and put the box in your suitcase or another box. If you put them directly in the suitcase or outside box, then other items will crush them. If you are only transporting chips, then put them directly in a box and add crumpled newspaper so they won't shift around too much.

Packing crisps (chips) in a suitcase without turning them into crumbs requires a "high-fidelity" protection strategy. The most effective method is using a sturdy, hard-shell plastic container with a secure lid; this provides a structural cage that shields the delicate bags from the pressure of heavier clothes or the rough handling of baggage systems. If you don't have a container, you can use the "air cushion" hack: open a small corner of the bag, blow air inside to inflate it like a balloon, and quickly reseal it with tape or a clip. This internal pressure helps the bag resist crushing. Another professional tip is to pack the bags in the center of your suitcase, surrounded by soft, rolled items like t-shirts or socks to act as shock absorbers. Always place your "crunchable" items at the very top of the bag just before closing it. For maximum safety, some travelers prefer to carry them in their hand luggage or a "personal item" bag to keep them out of the high-pressure environment of the aircraft's cargo hold.
