“Size matters! Too small and the cassette is likely to rip the bag, compromising sterility. Too big and takes up too much room in the autoclave and storage space. You gotta go with the Goldilocks approach and use the one that is just right.”  -Amanda Hill, BSDH, RDH CDIPC

Why Pouch Size Matters

Choosing the right pouch size isn’t just about fit—it’s essential for proper sterilization, drying, and long-term instrument safety. Here’s why it matters:

Ensures Complete Sterilization

Steam or vapor must reach all surfaces of the cassette and instruments. If the pouch is too tight, it can restrict airflow and result in incomplete sterilization.

  • “Steam must contact all surfaces of items being sterilized.”

Prevents Tearing or Seal Compromise

Pouches that are too small or overfilled are more likely to burst, tear, or lose seal integrity, especially during the sterilization cycle or when being handled after.

  • “Improperly sized pouches may be subject to damage during handling or sterilization.”

Supports Proper Drying

The right pouch size promotes full steam escape and complete drying during the sterilization cycle. When instruments remain damp, they’re at risk for rust, packaging failure, and contamination—all of which compromise sterility.

  • “Incomplete drying can lead to corrosion and microbial contamination during storage.”

Maintains Sterility in Storage

Pouches that are too tight can place stress on the seals and make long-term sterile storage unreliable, especially when stacked or compressed.

  • “Proper packaging is essential to maintain sterility until point-of-use.”
