Pouches made of medical-grade paper or heat-sealed foil are the best choice for steam sterilization because they are designed to allow the penetration of steam while providing a barrier to contaminants. The materials used in these pouches are breathable, which is essential for effective sterilization, as they need to permit steam to reach the items inside while preventing particles and microorganisms from entering once sterilization is complete.

Additionally, these materials help maintain sterility after the sterilization process until the point of use, ensuring that the instruments remain safe and effective for patient care. The heat-sealing process also ensures that the pouches are securely closed, minimizing the risk of contamination during storage and handling.

In contrast, other packaging options, such as plastic bags, may not allow adequate steam penetration or may melt during the sterilization process. Cardboard boxes can absorb moisture, which can lead to inadequate sterilization, and glass containers are heavy and may not provide the necessary barrier against environmental contaminants once opened. Thus, the selected option is the most suitable for ensuring effective steam sterilization and maintaining the sterility of instruments.
