FAQ

Poor sealing quality can be caused by the following factors:

1. Incorrect Temperature Settings: Temperature that is too low prevents proper adhesion, while excessively high temperature can cause melting and deformation.
2. Uneven Pressure or Insufficient Sealing Time: Uneven manual pressure or premature release can lead to inconsistent sealing and air leaks.
3. Wrinkles or Contaminants in the Seal Area: Unaligned pouch edges or contamination from moisture, oil, or powder will compromise seal integrity.
4. Wear and Tear of Machinery Parts: Worn-out heating wires, PTFE/Teflon tapes, or silicone pressure pads cause unstable heat conduction and pressure distribution.
5. Recommended Solutions:

• Adjust Settings: Ensure heat and sealing time parameters match the specific pouch material.
• Keep Sealing Surface Clean: Flatten the pouch opening and keep it clean; apply even pressure during operation.
• Replace Consumables Regularly: Periodically replace wearable parts such as heating wires and Teflon tapes.
• Inspect Continuous Sealers: Check that heating/cooling blocks are smooth, Teflon belts are intact, and the drive system operates properly.

Troubleshooting Heat Sealing Defects: Root Causes & Corrective Actions：
1.Insufficient or Excessive Temperature: Sealing temperatures set too low lead to incomplete bonding or weak seal 
   strength; temperatures set too high cause film burn-through, melting, or structural warping.
2.Uneven Sealing Pressure or Insufficient Dwell Time: Inconsistent manual pressure or premature handle release leads to localized
   seal   gaps or compromised hermetic tightness.
3.Wrinkles or Contaminants in the Seal Area: Failure to lay the pouch opening completely flat or the presence of liquid, powder, or
   grease across the sealing surface prevents complete thermal bonding and causes micro-leaks.
4.Wear & Degradation of Wear Parts: Exhaustion of standard consumable components—such as heating elements, PTFE/Teflon heat-
   resistant tape, or silicone pressure pads—results in erratic heat transfer and uneven mechanical clamping.
5.Recommended Solutions & Corrective Actions：

• Calibrate Parameters: Verify that heat sealing temperature, heating duration, and cooling dwell times strictly correspond to the film material and gauge thickness.
• Ensure Flatness & Cleanliness: Smooth out wrinkles at the pouch mouth, wipe away residue (oils, liquids, or powders), and apply uniform downward pressure during the sealing cycle.
• Routine Preventive Maintenance: Regularly inspect and replace wear-and-tear consumables, including resistance heating elements and PTFE/Teflon protective cloth.
• Inspection for Continuous Band Sealers: Check heating blocks, cooling blocks (copper/aluminum), and seamless PTFE Teflon guide belts for proper alignment, smooth rotation, cleanliness, and flat contact surfaces.
