1. First of all, we must look at the packaging identification and product instructions of the finished product: whether it is shipped aseptically or non-sterilely, the manufacturer's product instructions or finished product packaging should be clearly stated.
For medical gauze packaged in an aseptic way, the packaging mark must indicate: sterilization expiration date, ex-factory date or production lot number, packaging damage replacement instructions or logo, one-time use instructions or prohibition of re-use logo, check the product expiration date when purchasing, find Damaged packaging is no longer purchased or used.
2. Look at the appearance of the product. The product should be soft, odorless, tasteless, pure white in color, free of other fibers and processed substances, and reflect strong blue fluorescence under ultraviolet light.
