Which of the following packaging materials cannot be used for low-temperature gas plasma (LTGP)?

Low-temperature gas plasma (LTGP) sterilization is a process that uses hydrogen peroxide vapor to eliminate microorganisms. The selection of packaging materials for items to be sterilized using LTGP is crucial, as not all materials can withstand the conditions of this sterilization method.

The correct answer indicates that paper-plastic pouches should not be used for LTGP. This is because these pouches may not have the necessary barrier properties to maintain sterility or might degrade under the conditions of low-temperature gas plasma sterilization. Specifically, the plastic component of paper-plastic pouches is not always compatible with the gas plasma environment and may not effectively allow the sterilant to penetrate and reach the contents.

In contrast, the other materials mentioned—Tyvek and all-plastic pouches—are compatible with LTGP processes. Tyvek is a material commonly used in sterile packaging because it has a high level of breathability, providing an optimal environment that allows for effective sterilization while serving as a reliable barrier against contamination after sterilization. Similarly, all-plastic pouches made from materials designed for LTGP can withstand the sterilization process without compromising their structural integrity.

By understanding the characteristics and compatibility of packaging materials with LTGP, sterile processing technicians can ensure that items are
