How to pay attention to ten issues related to medical nonwoven fabrics in Saudi Arabia/Thailand?

With the continuous updating and rapid development of packaging materials for sterilized items, medical non-woven fabrics have gradually entered the disinfection supply centers of various hospitals at all levels as the final packaging material for sterilized items.

How to ensure the quality of medical non-woven fabrics? You must pay attention to these ten aspects of medical non-woven fabrics.



1.Medical nonwoven fabrics are different from ordinary non-woven fabrics and composite nonwoven fabrics. Ordinary nonwoven fabrics do not have antibacterial properties; Composite nonwoven fabric has good waterproof effect and poor breathability, and is generally used for surgical gowns and bed sheets; Medical nonwoven fabric is pressed using a process of spunbonded, melt blown, and spunbonded (SMS). It has the characteristics of bacteria resistance, hydrophobicity, breathability, and no shavings. It is used for the final packaging of sterilized items and is disposable without the need for cleaning.

2.Quality standard requirements for medical non-woven fabrics: Medical non-woven fabrics used as final packaging materials for sterilization of medical devices should comply with the specifications of GB/T19633 and YY/T0698.2 at the same time.
3.Non woven fabrics have a shelf life: Medical non-woven fabrics generally have a shelf life of 2-3 years, and the shelf life of products from different manufacturers may vary slightly. Please refer to the instructions for use. Sterile items packaged with medical non-woven fabrics should have a shelf life of 180 days and are not affected by sterilization methods.
4.It is advisable to add or subtract 5 grams of non-woven fabric from 50g/m2 for packaging sterilized items.
5.When packaging surgical instruments with medical non-woven fabrics, a closed packaging method should be used. Two layers of non-woven fabrics should be packaged in two times, and repeated folding can form a longer bending path to prevent microorganisms from “easily” entering the sterilization package. Two layers of non-woven fabrics cannot be packaged once.
6.After high-temperature sterilization, the internal results of medical non-woven fabrics may change, affecting the penetration and antibacterial properties of the sterilization medium. Therefore, medical non-woven fabrics should not be reused for sterilization.
7.Due to the hydrophobic properties of non-woven fabrics, excessive and heavy metal instruments undergo high-temperature sterilization, resulting in the formation of condensed water during the cooling process, which is prone to the formation of wet bags. Therefore, placing absorbent materials inside the large instrument package, appropriately reducing the loading capacity of the sterilizer, leaving gaps between sterilization packages, and appropriately extending the drying time to avoid the generation of wet packages as much as possible.
8.Hydrogen peroxide low-temperature plasma should use “Tewei Qiang” non-woven fabrics, and medical non-woven fabrics containing plant fibers cannot be used, as plant fibers will absorb hydrogen peroxide.
9.Although medical non-woven fabrics do not belong to medical devices, they are related to the sterilization quality of medical devices. As a packaging material, the quality of medical non-woven fabrics themselves and the packaging method are crucial to ensuring the level of sterility.
10.Refer to the qualified inspection reports and product batch inspection reports provided by the manufacturer, and conduct acceptance of the physical and chemical properties of medical non-woven fabrics to ensure the quality of the products used is qualified.



For the management of medical non-woven fabrics, the manufacturer is responsible for the production quality of medical non-woven fabrics, the hospital equipment department and infection office are responsible for the qualification review and quality acceptance of products, and the supply room personnel are responsible for the packaging quality of sterilized items. Only by implementing all four measures can the sterilization quality of medical devices be guaranteed.
