Reasons for unclear outline of heat sealing surface of middle sealing Bag Making Machine
The reason for the unclear outline of the heat sealing surface of the middle sealing Bag making machine:
1. Cooling time is short.
2. Poor contact of cooling plate.
3. As the silicone pad is heated, the edges are partially melted.
4. The longitudinal heat sealing force is uneven.
5. The edge of the heat sealing knife is irregular and blunt.
resolvent:
1. Adjust the cooling time.
2. Adjust the cooling plate.
3. Replace or adjust the heat sealing knife.
4. Do not allow the edge of the silicone pad to melt due to overheating.
