Medical Nonwoven Fabric The Structural Characteristics

Yiwu Guanghong Non-Woven Co.,Ltd | Updated: Aug 07, 2017

The main function of the sterile packaging material is to allow air and sterile media (such as steam) to pass through, Medical Nonwoven Fabric but also for the sterile items to provide biological barriers, and thus protect the sterilized items in the transfer and storage process to maintain a certain time Sterile state. China's sterile supply center used in the sterile packaging materials include: cotton, crepe paper, Zhisu bags, non-woven fabrics and hard containers.

In the selection of sterile packaging materials, Medical Nonwoven Fabric the hospital supply room or disinfection supply center is mainly based on its ease of use, sterile shelf life and price screening.

Medical paper and plastic bags are made of a layer of special paper and a layer of PET-PP plastic composite film by heat treatment, it is breathable and transparent and visible. Medical Nonwoven Fabric Transparent plastic film with a sterilization indicator on the side, can indicate whether the sterilization. Medical paper and plastic bags in the use of a special hot sealing machine on both ends of the seal, the drawback is a single breathable,Medical Nonwoven Fabric and some items (metal equipment, surgical shade) in the sterilization easily produce condensate, to be verified Can be used. General medical paper and plastic packaging bags of sterile sterile items for the effective sterilization period of 6 months, the specific period of sterile protection should be issued by the manufacturer shall prevail.

The method of loading the medical paper-plastic bag is to place the paper-to-plastic vertical sub-gap, because the relative paper is placed on the plastic vertical sub-gap, Medical Nonwoven Fabric the paper is placed on the paper with a slightly higher wet bag ratio, Placed or paper on the plastic stacked stacked is prone to wet bags and other sterilization failure phenomenon.

Medical non-woven packaging material is mainly made of polypropylene, which has a small fiber spacing and random arrangement of the structural characteristics, which can significantly reduce the possibility of microbial or dust particles transferred.

Medical non-woven packaging materials are disposable and can not be reused. In the choice of non-woven fabrics should be considered in the performance of non-woven fabric resistance, Medical Nonwoven Fabric tensile strength and permeability. Compared with the traditional cotton, medical non-woven fabrics have different characteristics: sterile package can be stored longer (generally double non-woven fabric for 6 months); disposable supplies, will not produce cotton dust and cause air pollution; With good ventilation and the balance of bacteria; medical non-woven fabrics for pressure steam sterilization, EO sterilization, but non-woven fabrics containing plant fiber is not suitable for low temperature plasma sterilization.

The quality of medical device sterilization is directly related to the quality of medical care and medical benefits increasingly rich. With the continuous development of sterilization technology, for the preservation of packaging materials increasingly rich. In the past, Medical Nonwoven Fabric medical equipment used double-layer plain cotton or unsealed hard container packaging sterilization. This kind of packaging has a short shelf life of sterilized items, shortening the service life of the equipment and reducing the cost of disinfection. At present, Medical Nonwoven Fabric the use of non-woven fabric of its special porous arrangement of the formation of a unique barrier can make the steam and other media bending into the package, Medical Nonwoven Fabric the bacteria and other microorganisms effectively separated from the advantages of the clinical essential but the use of low frequency of equipment and Part of the surgical equipment used non-woven packaging sterilization.
