Sterile Packaging models

The manual preparation of the following models is recognized worldwide for the packaging of medical use products in the SP:

  • Envelope type: This type is for small, rounded and light elements. The opening is made on the operator’s hand.
  • Rectangular type: This type is for large and heavy elements (boxes of instruments and packages of clothing). The opening is made on the table.
  • Paper bags: There is a considerable range of sizes, all of which need to be folded and sealed with tape or heat-sealed by machines. They should be made of medical grade paper, with bellows that facilitate aseptic opening, have a glossy interior side. If it has a printed chemical witness, it should be indelible to steam. The adhesive part of the bags should be resistant to sterilization processes.
  • Pouch or window package (paper – film): consists of a transparent folio or film front side that is sealed to the paper using heat. The folios can be made from polyester and polyethylene, or polyester and polypropylene.

Size of the package

For sterilization by steam (autoclave):

The size of the packages should not be larger than: 28 x 28 x 47 cm. If packages of 25 x 25 x 20 cm are used, exposure and drying times can be reduced. The weight should not exceed 4 to 5 kg.

For sterilization by dry heat:

Metal boxes should not contain more than 30 articles. It is not recommendable to use boxes made from common aluminum, since they can release aluminum particles into the instruments at high temperatures.
