Medical packaging bag is different with common packaging bag. Concretely, medical packaging bag is product’s primary inner packaging to sterilized medical apparatus and instruments.
Generally, medical packaging bag is used to pack sterile medical device or products ready to be sterilized and disinfected. Therefore, it is very strict in material choosing and manufacturing processes to produce qualified medical packaging bag. To maintain sterility of medical devices, producing medical packaging bag should pay special attention to below points in material, process property:
Firstly, medical packaging bag provides microbial barrier for packaging products, in short, it ensures microorganism without penetrating the product in sterilized and polluted packaging bag.
Secondly, when selecting materials, consider that the packaging materials must be able to allow air penetration and sterilization media penetration and precipitation, to avoid potential wet bag problems caused by tight grids or woven patterns.
Furthermore, when using medical packaging bags, it is necessary to avoid tearing or perforation, which is very likely to contaminate the medical products in the packaging bags. The packaging bags with the above quality problems must be reprocessed, which delays the time for the department to use the sterilized products. It also wastes time, manpower, material resources, and financial resources, so tear resistance and puncture resistance are also essential packaging characteristics of medical packaging bags.
Additionally, medical aseptic packaging must also ensure its own wear resistance to avoid weakening of the filter barrier and liquid resistance, and the stronger the wear resistance of the packaging material, the more durable it is. It should also be noted that surgical fires occur frequently every year around the world, so it is important to use materials with high flame resistance.
Medical packaging bags not only need to consider many of the above characteristics in material selection and production process, but also need to achieve a balance of these characteristics in order to become a perfect packaging choice.
