The correct method of using dental paper-plastic pouches

The correct method of using dental paper-plastic pouches is key to ensuring the sterilization and

protective effects of oral instruments. This not only requires adherence to certain operational standards,

also guarantees the quality and suitability of the packaging bags. The following will specifically introduce

their method of use:

1. Check for cleanliness and dryness:

• Before packaging, carefully inspect the items to be sterilized to ensure they are clean and completely dry. This is an important step to avoid wet packaging phenomena.

1. Choose the appropriate size of paper-plastic packaging bag:

• The size of the paper-plastic packaging bag should be selected based on the size of the oral instruments to be packaged. Common packaging diameters include 5 cm, 7.5 cm, and 10 cm.
• The sealing width should comply with the WS310.2-2016 standard, that is, it should be greater than or equal to 6mm.

1. Expel air:

• Before sealing, gently press the packaging bag to expel the air inside. This step can reduce the internal cold air, thereby reducing the production of condensation water during high-temperature sterilization, and thus lowering the risk of wet packaging.

1. Place concave side towards:

• For sterilizing objects with concave surfaces, place the concave side towards the dialysis paper to facilitate steam penetration and ensure sterilization effectiveness.

1. Stand vertically and maintain spacing:

• During sterilization, the paper-plastic packages should be stood vertically in divided shelves or loading baskets, with spaces between each package. This not only ensures effective penetration of the sterilization medium but also helps to dry the packages to be sterilized.

1. Sealing requirements:

• The seal should be flat and smooth, without burrs and gaps, to ensure a neat appearance of the package.
• Sealing materials need to have good heat resistance, corrosion resistance, and wear resistance to prevent damage during high-temperature sterilization processes.
• Ensure that the strength of the seal meets relevant industry standards, so that it is not easily damaged during normal use.

1. Storage and shelf life:

• After standard sterilization, it should be stored under suitable conditions of temperature, humidity, and cleanliness. The shelf life of sterilized paper-plastic packaging bags is usually 180 days[^1^].
• Before use, check whether the paper-plastic sterilization pouch is within its shelf life to ensure its sterile state.

In summary, the correct method of using dental paper-plastic pouches includes pretreatment of

instruments, selection of packaging materials, sealing treatment, and management of storage and shelf

life after sterilization. Each step must be strictly carried out according to standards to ensure the sterile

state of oral instruments and the safety of patients.
