Can different laminated films affect packaging machine performance?

• Yes, film thickness, COF, and sealant melting point directly change machine settings.
• Large COF differences cause film wandering or breakage; readjust film tension and edge guide.
• Different sealant melting points require resetting heat-seal jaw temperature, pressure, and time.
• Thickness or stiffness changes affect former and pulling roller gaps, causing bag length drift.
• After film changeover, run seal and tracking tests to confirm seal strength and stable cycle time.
