Why plastic bottles need careful specification
Lightweight containers can deform if collation pressure, conveyor handling or tunnel heat is unsuitable. A practical quote should consider bottle fill level, label position, cap height and whether packs are transported or displayed.
Film and tunnel considerations
The shrink tunnel must deliver enough dwell time and airflow for film recovery without overheating the bottle, label or cap. The correct tunnel aperture and conveyor speed are therefore part of the machine specification.
Integration with existing production
Bottle spacing, guide rails, pack counting and discharge conveyors influence how reliably the sleeve sealer receives and releases the multipack.
