Aluminum foil is the packaging of choice for dry heat sterilization due to its ability to withstand high temperatures without melting or compromising the integrity of the materials contained within. Dry heat sterilization involves elevated temperatures typically ranging from 160 to 180 degrees Celsius (320 to 356 degrees Fahrenheit), which can be achieved effectively using aluminum foil.

This material is impermeable to moisture and allows for proper heat penetration, making it suitable for maintaining the sterility of instruments during cycles that can last several hours. Additionally, aluminum foil can be tightly wrapped around instruments, helping to prevent any contamination after the sterilization process.

In contrast, other options may not provide the necessary qualities for effective dry heat sterilization. Paper bags, while breathable, can absorb moisture and would not maintain sterility under the conditions required. Plastic wraps may melt or deform at the high temperatures used in dry heat sterilization, compromising the items inside. Glass containers, while they can withstand high temperatures, may not provide sufficient protection against contaminants during storage or transport, limiting their effectiveness compared to aluminum foil.
