Complete guide: Sterilization self-sealing bags for autoclave 90x250mm 100 pieces
These self-sealing bags are the essential consumable for any tattoo studio or clinic that sterilizes reusable instruments in an autoclave. They are made of medical paper on one side and transparent plastic film on the other, so you can see the contents without opening the package. The 90x250 mm format is suitable for medium-sized instruments, and the pack contains 100 pieces. The integrated adhesive strip seals the bag airtight without any sealing machine, and the indicator impregnated in the paper visually confirms that the sterilization process has taken place.
How to use
- Clean the instruments before packaging and, where applicable, open or disassemble them; protect sharp tips to prevent perforation of the packaging.
- Insert the instruments into the bag and press to remove as much air as possible.
- Remove the foil protecting the adhesive strip and press firmly on the open edge for an airtight seal — no sealing machine is needed.
- Place each package in the autoclave, avoiding direct contact with the metal tray of the device.
- Run a steam sterilization cycle at 121-134 °C (the product is approved for a maximum of 30 minutes in steam).
- Check the color change of the indicator: during steam sterilization it changes from pink to brown (during ethylene oxide sterilization, from blue to orange).
- Let the bags cool for 5-10 minutes in the sterilizer; for faster cooling, you can leave the device door wide open.
- Store the sealed and intact packages until use and open them only when you need the instrument.
Tips from us
- Use a single bag for one instrument or set — bags are single-use and cannot be sterilized a second time.
- Choose the size based on the volume of the instruments; the 90x250 mm format fits grips, forceps, tubes, and needle sets.
- Write the sterilization date and contents on the paper side before running the cycle to quickly identify packages.
- Do not overfill the bag: instruments must fit without straining the sealing strip or stretching the plastic film.
- Before use, check the integrity of the packaging — if it is perforated, wet, or unsealed, resterilize the instrument in a new bag.
Warning: The color change of the indicator only confirms exposure to the sterilization process, it does not automatically guarantee complete sterility of the contents — follow the correct temperature and time parameters and your autoclave instructions. Bags that have been used or have compromised packaging (perforated, opened, wet) must be discarded and not reused. Sterility is maintained only as long as the packaging remains intact and properly sealed; check the product label for the sterilization shelf life.
