Commercial guide
A simple ROI calculation helps compare manual wrapping, chamber sealing, semi-automatic L sealing and automatic L sealer lines.

A simple ROI calculation helps compare manual wrapping, chamber sealing, semi-automatic L sealing and automatic L sealer lines.
Start with current cost per pack, then compare projected cost after installing a better shrink wrapping route. Include labour, film, rejects and downtime.
The calculation should support machine selection, not replace a technical specification review. A wrong machine can harm ROI even if it looks faster on paper.
| Pack dimensions | Largest and smallest product sizes, pack weight, stability and whether products are single cartons, bundles or trays. |
|---|---|
| Required output | Target packs per minute, daily volume, shift length, changeover frequency and whether future output may increase. |
| Film and finish | Preferred shrink film if known, presentation requirements, seal position, retail display needs and barcode visibility. |
| Line layout | Available floor space, infeed method, conveyor height, power, compressed air and whether a shrink tunnel is needed. |
