When this search applies
Pack dimensions are the first detail needed for a reliable L sealer recommendation because they drive sealing aperture, film width and tunnel chamber selection.
- Measure length, width and height
- Include product weight and stability
- Check largest and smallest packs
- Allow for film and seal clearance
How to measure
Measure the packed product in the orientation it will enter the machine. Include any raised lids, loose contents, irregular edges or unstable shapes.
Why the largest pack is not enough
The smallest pack matters too. A line that handles the biggest pack may still be awkward or wasteful for smaller repeat products.
Information to send for an accurate recommendation

| 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. |
