Sleeve sealing cartons and boxes

Cartons and boxes can be suitable for sleeve sealing when the pack format, film route and shrink tunnel are matched to the product. The machine choice depends on pack size, pack weight, output and how square or stable the pack remains through the tunnel.

A carton sleeve sealer may be used for grouped boxes, tray packs or transit packs where the film is used to hold the load together or add handling security. Conveyor height and outfeed handling should be considered early in the project.

Lancing can review carton dimensions, pack count and production speed to advise whether a sleeve sealer, L sealer or other shrink wrapping route is the better starting point.

Carton bundle engineering

Carton sleeve sealers must control flat-sided packs without damaging presentation

Carton shrink wrapping and carton bundling normally use the same sleeve-wrapper process, but flat faces and sharp edges create different film and handling conditions from round bottles or cans. The group must remain square while the film tightens and during downstream stacking or pallet handling.

Check surfaces, edges and compression

Gloss coatings, printed faces, open flaps, corner damage and inconsistent carton dimensions can affect friction and film contact. Excess shrink force or local heat may mark presentation surfaces, while insufficient containment can allow the group to rack. Use production cartons containing representative weight and internal support during the trial.

Confirm whether cartons are presented in one layer or multiple layers, the intended seam location, the permitted film marks and the stacking load after cooling. The discharge and accumulation arrangement should support the whole bundle without catching the seal or pressing hot film against sharp guides.
