Precautions for hot sealing of sterilization medical device packaging heat sealing machine
I. Equipment Preparation and Inspection
- Cleanliness: Ensure the heat sealer is thoroughly cleaned to prevent impurities from affecting sealing quality.
- Power and Air Pump: Verify that the power cord is securely connected to the socket, the air pump is properly linked, and the working pressure is set appropriately.
- Thermal Insulation Blanket: Check that the insulation blanket is intact, undamaged, and free from aging.
- Component Connections: Confirm all parts of the sealer are tightly connected without looseness.
II. Operational Process Control
- Preheating and Settings: After startup, allow the sealer to preheat to its normal operating state. Adjust sealing time and cooling time according to the medical device packaging material specifications.
- Seal Quality Verification: Use test waste bags for initial sealing after startup to ensure a secure seal with no air leakage.
- Standardized Operation: After placing products into the packaging bags as required, clean the bag opening thoroughly, align it properly, position it in the heating zone, and press the foot pedal swiftly to seal.
III. Heat Sealing Parameter Adjustments
- Temperature Control: Heat sealing temperature is critical. Adjust it based on the material type, thickness, and heat sensitivity.
- Insufficient temperature may weaken the seal.
- Excessive temperature risks damaging the packaging material.
- Time and Pressure:
- Ensure sufficient sealing time for proper material fusion but avoid overexposure to prevent scorching.
- Apply appropriate pressure to enhance material contact and bonding.
IV. Safety and Maintenance
- Safe Operation: Never place fingers or any body parts between the upper and lower heat-sealing plates to prevent burns. Follow all safety protocols strictly.
- Daily Cleaning and Maintenance: Clean the equipment surface daily to prevent dust buildup. Replace insulation blankets and worn parts (e.g., heating wires) periodically to ensure optimal performance.
V. Additional Precautions
- Material Selection: Use medical device packaging materials compliant with sterilization requirements, ensuring excellent barrier properties and sterilization resistance.
- Environmental Control: Maintain proper temperature and humidity in the workspace to avoid adverse effects on sealing quality.
- Personnel Training: Train operators thoroughly on equipment operation, safety protocols, and troubleshooting common issues.
