The sterile barrier properties of spunbond are lost after use

According to research, the shelf life of sterile items is closely related to the thickness of the cloth (g/m2) and the number of layers of the cloth.

Disposable non-woven packaging materials, after a series of high-temperature steam sterilization and chemical washing, the spunbond fiber structure is deformed, the cloth holes are sparse, the thickness decreases, and even small holes that are not easily detectable by the naked eye appear, and the antibacterial rate will drop suddenly Or lose the antibacterial performance, and the storage after sterilization cannot reach the safe expiration date. The requirements of the "Disinfection Technical Specification" for packaging materials: during the sterilization process, the sterilization factor must be effectively penetrated;
