Complete guide: Sterilization self-sealing bags for autoclave 90x250mm 10 pieces
The 90x250mm self-sealing bags are the essential consumable for sterilizing and keeping reusable instruments sterile in a tattoo studio or clinic: grips, forceps, small scissors, or needle sets. They are made of medical paper on one side and transparent plastic film on the other, allowing steam to penetrate during the process, while after sterilization the package remains an airtight barrier. The set contains 10 pieces and you don't need any sealing machine: each bag has its own adhesive strip. They are compatible with both steam autoclave and ethylene oxide sterilization.
How to use
- Clean and thoroughly dry instruments before packaging - organic residues prevent proper sterilization. Open or disassemble articulated instruments (forceps, scissors) and protect sharp tips.
- Insert a single instrument (or a single set) into the bag. The rule is one product per bag, so you can open the sterile package exactly when needed.
- Press the bag to remove all air inside before sealing.
- Remove the protective film from the adhesive strip and press the open end along its entire length for an airtight seal.
- Place each package in the sterilizer, avoiding direct contact with the metal tray of the machine.
- Run the steam sterilization cycle at 121-134 °C, maximum 30 minutes (the product is approved for this range).
- Let the bags cool for 5-10 minutes in the sterilizer after the cycle ends; for faster cooling, you can leave the door wide open.
- Check the indicator before use: during steam sterilization the color changes from pink to brown (for ethylene oxide, from blue to orange). Keep the bag sealed until the moment of use.
Tips from us
- Write the sterilization date on the bag to follow the order of use and control the package's validity.
- Do not overload the bag: leave enough space at the adhesive strip end for proper sealing and air removal.
- Store sterilized bags in a clean, dry place, protected from moisture and mechanical damage.
- Check the indicator every time before opening a package - if the color hasn't changed, do not use the instrument, but resterilize it.
- Open the bag by pulling from the end, do not puncture it, to keep the tip sterile; use the instrument immediately after opening.
- Maintain a constant stock: as a daily consumable, a set of 10 pieces is quickly used up in an active studio.
Warning: Bags are single-use: once opened or used, they are discarded, as they cannot be sterilized a second time. Instruments must be cleaned and dried before packaging - sterilization does not clean dirt. The indicator only confirms that the package has been exposed to the sterilization process, it does not guarantee sterility on its own; this depends on a correct and complete autoclave cycle. Do not use any package if the packaging is damaged, wet, or unsealed - in this case, the instrument must be resterilized. Follow your studio's sanitary protocol; correct use of the bags is a mandatory requirement for compliance with hygiene standards.
