Packaging Flashcards

Which packaging material provides both a microbial barrier and allows sterilant penetration for steam sterilization?

SMS (spunbond-meltblown-spunbond) nonwoven wrap allows steam penetration while maintaining an effective microbial barrier.

What is the minimum seal width recommended for heat-sealed pouches used in sterile packaging?

Answer: 3 mm

A minimum seal width of 3 mm is required to ensure an adequate seal integrity for sterile packaging pouches.

When double-pouching an item for sterilization, how should the inner pouch be oriented inside the outer pouch?

Answer: Paper side facing the plastic side of the outer pouch

The paper side of the inner pouch should face the plastic side of the outer pouch to ensure proper sterilant penetration and aseptic presentation.

Which test is used to assess the integrity of a heat seal on a sterilization pouch?

Answer: Peel test

The peel test evaluates heat seal integrity by assessing the bond strength and identifying delamination or channel defects.

What does the term 'dead space' refer to in the context of rigid sterilization containers?

Answer: Areas inside the container where sterilant cannot reach

Dead space refers to areas within a rigid container where sterilant (steam or gas) cannot adequately contact surfaces, risking sterilization failure.

Which factor most directly affects the shelf life of a sterile packaged item?

Answer: Storage and handling conditions

Shelf life is event-related and primarily determined by storage and handling conditions such as humidity, temperature, and traffic.

What is the purpose of a sterilization chemical indicator placed inside a package?
