Poor Sealing Of Paper Plastic Packaging Is A Common Failure During Packaging

Packaging precautions for paper plastic packaging machines:
1. Keep the sealing surface clean and avoid oxidation of residues on the sealing surface, which can reduce the lifespan of the heating strip.
2. Do not wipe the sealing surface with a damp cloth.
3. When replacing the electric heating strip, the integrity of the gasket should be checked. If there is any damage, it should be replaced in a timely manner.
4. After prolonged use, the sealing position should be checked to avoid loose sealing.
Poor sealing is one of the common faults in paper plastic packaging machines:
1. The sealing part of the packaging cannot be sealed.
2. Under the pressure of the sealing knife, although the packaging area needs to be sealed, slight pressure or tearing can cause the sealing to crack again.
3. When conducting peeling tests on the sealing area, there was a phenomenon of half being firmly sealed and half being separated.
4. Moisture and dirt at the packaging area can also cause poor sealing.
