How long is a sterile instrument kept in a Kraft bag

Types of sterilization packaging and their storage methods.

The main function of packaging is to protect sterile material from re-suspension by microorganisms (recontamination). Unwrapped sterile material is useless because it is not sterile. Products sterilized without packaging must be used immediately after sterilization. Sterilization with dry heat or wet material in a package helps to keep products sterile. Sterilization packaging materials should be easily permeable to the appropriate sterilizing agents, closed impermeable to microorganisms and maintain integrity after sterilization by an appropriate method.

For packaging we use reusable sterilization bins (boxes), different Kraft bags, modern packing materials.

sterile, instrument, kraft

Sterilized are dry products in packages of unimpregnated paper (Kraft-packages), wet sack paper. There are packages of double-layer cotton fabric corresponding to OST 42-21-2-85. Shelf life of sterility depends on packaging. Bix without filter are stored for three days, with a filter. 20 days. Packages made of double-layer x-woven fabric conforming to OST 42-21-2-85.-б. Tissue or kraft bags can be stored for up to three days in sterile conditions. All packages are marked.

Three varieties of pouches are manufactured according to the chemical indicator:

-with chemical indicator of steam sterilization ISPS

-with chemical indicator of air sterilization ISPS.

-with a chemical indicator of steam and air sterilization IE “VINAR”

Since 1998, the Ministry of Health authorized the use of imported paper bags meeting international standards. Shelf life of such pouches is 20 days. Self-adhesive bags made of moisture-resistant paper for steam and air sterilization are used today. On the outside of the package is printed chemical indicator of class 1 with the indication of the corresponding sterilization method and the description of the final color of the indicator to be acquired after sterilization. The bags are hermetically sealed with self-adhesive tape on the pouch flap without any additional equipment.

Storage of products sterilized in packaged form in cabinets, workbenches. Storage times are indicated on the package and depend on the type of packaging material according to the instructions for its use.

Type of package Shelf life of the pouches before package opening Shelf life after package opening
Bix with bactericidal filter (BFSC) 20 days filter change for 21(61) sterilization 6 hours
2-layer calico 3 days 6 hours
Kraft bag 20 days
Combination packs (plastic-pergament) 20 days for adhesive tape; 4 to 6 months for rolled or self-adhesive
Moisture-proof paper-package 20 days

The main function of packaging is to protect sterile material from re-insemination by microorganisms (recontamination). Without packaging, sterile material is useless, because it is not sterile. Products sterilized without packaging must be used immediately after sterilization. Sterilization with dry heat or moist material in a package helps to maintain sterility of products. Sterilization packaging materials must be easily permeable to the corresponding sterilizing agents, closed impermeable to microorganisms and maintain integrity after sterilization using an appropriate method.

For packaging we use reusable sterilization bins (boxes), different Kraft bags, modern packaging materials.

Dry products in packages of unimpregnated paper (Kraft-packages), water resistant paper sacks are subject to sterilization. There are double-layer cotton pouches conforming to OST 42-21-2-85. Shelf life of sterile depends on packaging. Bix without filter are stored for three days, with filter. 20 days. Packages made of double-layer x.-б. Cloth or Kraft bags are stored for up to three days in sterile conditions. All packages are labeled.

Depending on the chemical indicator the packages are made in three varieties:

-with the chemical indicator of steam sterilization ISPS

-with the chemical indicator of air sterilization ISPS.

-with chemical indicator for steam and air sterilization IE VINAR

Since 1998, the Ministry of Health has authorized the use of imported paper bags that meet the requirements of the international standard. Shelf life of such packages is 20 days. Today we use self-adhesive pouches made of moisture-proof paper for steam and air sterilization. Applies a grade 1 chemical indicator on the outside of the pouch indicating the appropriate sterilization method and describing the final color of the indicator to be acquired after sterilization. The bags are hermetically sealed with self-adhesive tape on the pouch flap without using any additional equipment.

Products sterilized in packaged form are stored in cabinets, work tables. Storage times are indicated on the packaging and are determined by the type of packaging material according to the instructions for its use.

Kraft bag for sterilization. An ingenious way to keep items sterile

The choice of sterilization bag depends on the equipment in which the instruments are to be sterilized. Kraft bags for sterilization of instruments are divided into several categories:

  • For steam sterilization. They are products made of paper on one side and transparent film on the other. Suitable for use in pressure cooker sterilizers.
  • For air sterilization. Made entirely of paper. Used for sterilization through hot air. the instrument is placed in an oven and disinfected at 180-200C.
  • Universal.

They can also be differentiated by color (white or brown), self-adhesive tape, method of sealing, presence and type of indication, and many others. But the main difference is in the sterilization conditions.

Types and Applications

Kraft pouches for sterilizing medical instruments like syringes, pipettes, tubes, scalpels, tweezers, etc.

For sterile packaging of medical instruments and materials.

For sterilization, packaging of tools and materials of chemical, pharmaceutical industry.

For hermetic packaging of food products.

For packing of various industrial products.

Kraft bags with handles and logos. one of the means of advertising companies.

Indicator will change color depending on the sterilisation method:. For air sterilisation (sterilization in a drying cabinet) the color of the indicator on the bag should change from pink to brown;. With steam (autoclave sterilization). from pink to gray.

Before sterilizing, I put the instruments in kraft bags. They have a special indicator on them, which shows that the tool is sterile. Indicator is beige when the bag is put in the oven and purple when it is taken out. The client can be guided by it. told the master of manicure Inna I.

Place instruments in self-adhesive kraft sterilization bags and seal them. Sterilize instruments in a dry oven at 180°C, for 1 hour. Do not exceed specified temperature and holding time!

White pouches are more expensive than brown pouches but don’t release odors during sterilization. Suitable for sterilization. 350 R Vinard Brown Paper Kraft pouches for dry-heat sterilization which keep your instruments sterile and keep germs out when closed, preventing recontamination.

The indicator changes color depending on the sterilization method:. The color of the indicator on the bag should change from pink to brown when using the air method (sterilization in a dry oven);. When steam sterilized (autoclave sterilization). from pink to gray.

White pouches are more expensive than brown pouches, but do not emit odors during sterilization. Suitable for sterilization. 350 P Vinard “Sterit” brown paper kraft pouches for dry-heat sterilization, keep instruments sterile and keep germs out when closed, preventing re-contamination.

Terms of storage of sterile materials in sterilisation boxes (beakers). 3 days. If this sterilization box has been opened, these materials are allowed to be used within 24 hours after opening (after which the side openings in the sterilization box must be opened).
