What are the sealing requirements for final sterilization packaging
Core sealing requirements:
1. Seal width: For paper-plastic bags, the seal width should be ≥6mm; the distance from the instrument inside to the edge of the seal should be ≥2.5cm.
2. Seal continuity: The seal must be continuous and complete, without pinholes, bubbles, channels, cracks, delamination, or other defects.
3. Seal strength: For steam sterilization, the seal strength should be ≥1.5N/15mm; for EO/plasma sterilization, it should be ≥1.2N/15mm. It must maintain a stable microbial barrier after sterilization, and the dialysis paper should not generate paper debris that contaminates instruments when peeled off.
4. Parameter validation: Seal temperature, pressure, and speed must be process-verified, and a seal integrity test should be done daily before use.
5. Integrity of closure: The sealing barrier capability should not be lower than that of the packaging itself, effectively preventing microbial intrusion throughout sterilization, transport, and storage.
6.The thermal sealing performance of packaging materials directly affects seal quality. In practical operations, it is generally divided into high and low temperature. MDcare sealing machine is not only easy to adjust temperature, stable in quality, but also small in size and light in weight, making it stand out among similar sealing machines.
