The importance of sterilization packaging mask

Sterilization packaging of medical devices is divided into protective packaging and sterile barrier system (SBS). The latter is the key component of sterilization packaging and the main focus of sterilization packaging industry. The construction of aseptic barrier system depends on the appropriate sterilization package. A qualified sterilization package must meet the requirements of sterilization adaptability, microbial barrier, firmness, biocompatibility and toxicology, physical and chemical characteristics, aging resistance and other aspects, and the performance of sterilization package largely depends on the performance of packaging materials.
 

Sterilization packaging of medical devices

For example, the sterilization adaptability of ethylene oxide requires that the material has sufficient air permeability to ensure that there is less or no gas residue after sterilization when steam penetrates; radiation sterilization does not require that the material has air permeability, but gamma ray or high-energy electron beam may damage the polymer material, making the material brittle and easy to crack, so p cannot be used in general P. PVC and other materials. For another example, in terms of microbial barrier, under the long-term penetration of high-temperature steam, the permeability material may lose its barrier ability, and the qualified sterilization packaging material must be able to maintain the microbial barrier ability after sterilization.
One of the best experiments to evaluate the air permeability of packaging materials for medical devices is to measure the air permeability of iso5635-5. The experiment uses a device called a densitometer, which uses a cylinder pulled down by gravity to move a known volume of air through porous material. The more porous the material, the faster the cylinder will fall.
