Poor tape adhesion
Check carton board quality, tape adhesive, tape pressure and whether the carton flaps are fully closed before sealing. Cold or dusty environments can also affect tape performance.
Tape not cutting cleanly
Inspect the blade, blade spring, tape path and adhesive build-up. A dull or contaminated blade can leave ragged cuts or drag tape through the machine.
Carton jams or skewing
Check side guides, belt pressure, carton weight, overfilled cases and transfer points before and after the machine. Cases should enter squarely and remain stable through the sealer.
When to ask for service help
If repeated adjustment does not solve the issue, send photos or video of the problem, the machine type, tape used and carton dimensions so the likely cause can be narrowed down.
Next step
For a practical recommendation, send carton dimensions, packed case weight, tape details, target output and photos of the current packing area. The aim is to match the case taper to your cartons and workflow, not to force a standard machine into the wrong process.
