The packages for surgical sutures are used according to the nature of the suture and its intended use. In general the ideal packaging maintains and protects the suture during handling and storage, also allows the suture ready to be removed from its packaging with a minimum of handling and difficulty.
REQUIREMENTS OF PACKING MATERIAL
- Permeable to sterilizing agent
- Resistant to microorganisms entrance
- Resistant to breakage
- Do not leave fibers or particles
- Do not react with the sterilizing agent
- Do not react with the packing material
- Resistant to liquids
- Non-toxic (inks, fibers, fluff)
- Cost / benefit positive ratio
For dry absorbable sutures (Braided Black Silk, Nylon Monofilament, etc) Surgical Grade Paper Envelopes are used.
For Synthetic absorbable sutures (Polyglycolic acid, polyglactin, polydioxanone, polyglecaprone) aluminum envelopes are used.
For Absorbable Sutures (Chromic Catgut, Catgut Simple) F4 Film envelopes are used
ENVELOPES OF PAPER SURGICAL GRADE
This is the ideal material for the sterilization process. In its development no optical bleaching are added. The weight is 60 to 65 g/m2, neutral pH and has high tear resistance.
It consists of a binding glue and cellulose fiber for extra long fibers having high strength, this leads to high mechanical stability. Cellulose fibers are linked into a sheet using a glue, in this case a moisture resistant glue, this is needed to make the paper resistant to sterilization and during storage to protect the product against humidity, otherwise should lead to contamination.
