Aluminum foil is better at keeping things colder than plastic wrap. This is because foil reflects light and heat, including the sun's rays, helping to insulate the contents from external temperatures. In contrast, plastic wrap is thinner and not as effective at blocking heat transfer. For optimal cooling, wrap items in aluminum foil and place them in a cooler or refrigerator. However, remember that foil cannot seal items as tightly as plastic wrap, so it's best used for short-term cooling needs.
