When this search applies

Most L sealer routes use centre fold shrink film, and selecting the correct width is essential for presentation and waste control.

Film width should be selected around the pack width and height, with enough allowance for wrapping and sealing without excessive waste.

Poor roll alignment or tension can create weak seals, uneven shrink and unnecessary scrap. Film loading should be part of operator training.

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.
