The Influence of Uneven Cutting Force Distribution on Packaging Quality
1.Uneven trimming, burrs, and drawing
Uneven force → incomplete local cutting → easy leakage at seals and poor appearance.
2.Poor sealing, air or liquid leakage
Burrs on cuts → weak heat sealing → decreased qualified product rate.
3.Dimensional deviation and misalignment during cutting
Force fluctuation → material deviation → unstable bag length/position.
4.High noise, strong vibration, obvious knife marks
High impact → film surface scratches and deformed printed patterns.
5.Uneven blade wear and chipping
Excessive local force → shortened service life and frequent blade replacement.
6.Low packaging efficiency and high reject rate
Increased material breakage, jamming, and downtime → increased costs.
Summary in one sentence:
The more uniform the cutting force, the smoother the cut, the more reliable the seal, and the fewer defective products.
