"Food fresh longer: How does aluminum foil achieve this?"

Aluminum foil’s remarkable ability to extend food freshness hinges on its exceptional barrier properties. Unlike many other packaging materials, aluminum foil is impervious to light, moisture, oxygen, and bacteria. This impermeability is crucial because these elements are primary culprits in food spoilage.

Moisture fosters microbial growth, accelerating decay. By forming a complete barrier, aluminum foil effectively isolates food from these detrimental factors. This isolation maintains the food’s original quality, preserving its taste, texture, and nutritional value for a longer period. Furthermore, aluminum foil’s thermal conductivity plays a supporting role.
