Cans can be difficult to handle because round products move easily until the pack is contained. Before specifying a sleeve sealer, the can diameter, pack count, tray use and infeed presentation need to be reviewed.
For trayless can multipacks, collation and stability become especially important. For tray packs, the tray may support the group, but film overlap, tunnel heat and discharge handling still need to be matched to the finished pack.

Can multipack sleeve sealing
Product shape
Round products need stable collation and controlled transfer.
Film route
PE shrink film is commonly considered for multipack transit wrapping.
Integration
Infeed, grouping, tunnel and outfeed should be planned together.

Trayless can packs may be possible when collation and transfer are stable enough, but this needs checking against the product and output target.
What film is used for can multipacks?
PE shrink film is often considered for transit multipacks, subject to pack weight, shrink finish and machine settings.

Can shrink wrapping depends on collation, support and cooled-pack handling
A can sleeve sealer must hold the intended pattern through film feed, sealing and the shrink tunnel without damaging presentation or allowing the pack to lose alignment. The required route changes with can height, diameter, surface finish, bundle count and the use of a tray or pad.
Protect the pack pattern
Round cans can roll or open gaps if lane pressure, transfer timing or side guides are inconsistent. Confirm the pattern at normal speed and during stop-and-restart conditions.
Control film contact
Film overlap and shrink force should contain the bundle without creating unacceptable marking or distortion. Trial the actual printed surface, can ends and any tray or board edges.
Cool before accumulation
Bundles should stabilise before close accumulation, lifting or pallet contact. The accepted pack should remain square after the normal discharge and handling sequence.
Can multipacks need controlled collation before the film is sealed
Can sleeve sealing works best when the can group reaches the wrapper square, evenly spaced and supported enough to resist rotation or spreading. Label surface, can height, pack count, tray support and conveyor transfer points can all influence whether the group stays together until the PE film shrinks.
Where cans are light, narrow or unstable, the collation route may need more attention than the sealer itself. The test should include restarts, missing-can conditions and discharge behaviour after the tunnel.
