What type of packaging is suitable for dry heat sterilization?

Aluminum foil is suitable for dry heat sterilization because it can withstand the high temperatures used in this method without melting or warping. It provides a barrier to moisture and microorganisms while allowing dry heat to penetrate effectively. This makes aluminum foil an excellent choice for wrapping instruments or materials that are to be sterilized using dry heat.

In contrast, plastic wraps are typically not suitable because they may not endure the elevated temperatures and can melt, compromising the integrity of the sterilization process. Paper envelopes might also be less effective in withstand the extreme dryness and temperatures of dry heat sterilization, as they can become fragile or degrade under such conditions. Glass containers can be used in dry heat sterilization, but they are often not the preferred choice compared to aluminum foil since the glass may be heavier and less convenient for certain applications.
