How to Adjust If the Bag Sealing Is Not Good?

If the bag sealing is not firm or appears incomplete, the issue is usually related to improper sealing parameters or contamination on the sealing area. First, increase the sealing temperature or extend the sealing time to allow the packaging film to melt and bond properly.

Next, check whether the sealing area is clean. Dust, powder, or product residue on the sealing surface may prevent proper sealing. It is also important to confirm that the sealing temperature matches the packaging film material, since different films require different heat levels.

Additionally, inspect the sealing components of the machine, including the heating elements, sealing bars, and pressure system, to ensure they are working correctly and providing even heat and sufficient pressure.

After making adjustments, run several test bags to verify that the seal is strong, smooth, and consistent.
