The medical packaging bag with medical dialysis paper on one side and medical composite film on the other side can be respectively suitable for sterilization packaging irradiated by EO ethylene oxide, high-temperature steam and gamma cobalt Co60 rays, such as high-temperature steam disinfection or sterilization of medical devices by hospitals.
Medical packaging bag manufacturers, such as syringes, catheters, probes, gauze pieces, surgical clothes, artificial bones, artificial organs, electric pens, knives and other sterile medical products, generally steam sterilization for a few minutes to half an hour, the temperature is 121-134 degrees, ethylene oxide sterilization for a few hours, the temperature is about 55 degrees, and irradiation is sterilized at room temperature, which can be completed in about 2 minutes.
Pet (polyester) / PE (polyethylene) colorless transparent medical composite film is not suitable for high-temperature sterilization, because PE itself is not resistant to high temperature and glue is not resistant to high temperature. Pet (polyester) / CPP (polypropylene) is not recommended for irradiation sterilization.
Because irradiation rays have aging and embrittlement effect on CPP, harmful halides may also be precipitated.
Generally, the products are put into bags in clean workshops, such as 100000 level purification workshops, and then the disposable sterile medical devices are sealed with a heat sealing machine, put into cartons, and put into a sterilization cabinet for sterilization.
After sterilization is OK, generally, due to different materials, the bacteria resistance and quality assurance period is generally divided into 1 year, 3 years and 5 years, all of which have been aging verified, so as to ensure transportation, Store until the hospital nurse opens it.
The medical products in the bag are sterile products. They can be used directly without sterilization.
What should we pay attention to when using medical packaging bag?
In modern life, many things pay more and more attention to packaging. What we use more are plastic packaging bags and paper plastic packaging bags. We are very familiar with these two kinds.
But now there are many kinds of packaging products. What should we pay attention to when we use them?
When packaging a single instrument, paper and plastic packaging materials with appropriate size shall be selected; Sharp tools should be wrapped with small yarn pieces and then put into paper plastic packaging to prevent the packaging bag from being pierced during storage and transportation.
When packaging instruments, the remaining space at one end of the seal is slightly larger, and the articles are 3 ~ 5cm away from the seal, so as to prevent wrinkles of paper and medical packaging bag during sealing.
When the articles to be sterilized are put into the pot, they shall be packed in stainless steel baskets, standing on the side. If the plastic is placed flat on the top, the water may stay on the plastic surface; The plastic surface shall not be in direct contact with the plastic surface.

The sealing machine with the temperature of 150 ~ 180 ℃ shall be selected, the temperature shall be adjusted at 180 ℃, the width of plastic sealing strip shall be 2 cm, and double-layer sealing shall be adopted to ensure the tightness and anti tension of sealing.
When taking and placing, hold the paper layer flat by hand. When checking the packaging, do not squeeze, there is resistance and there is no damage. It is forbidden to put the package upside down and drag it by hand to prevent one side of the paper from being torn. The inspection method of paper plastic packaging bag is adopted when using.
After sterilization, pay attention to check the color code discoloration and bag sealing, and pay attention to the moisture-proof and sharp tool puncture of the paper layer. Pay attention to check whether there is damage during use. If there is damage, it is strictly prohibited to use.
