What a sleeve sealer machine does
A sleeve sealer machine wraps film around a grouped product and seals the film sleeve before the pack travels through a heat shrink tunnel. The result is a stable shrink-wrapped multipack for transport, retail handling or production line collation.
The best machine route depends on the finished pack rather than the machine name. Bottles, cans, trays, cartons and grouped products all behave differently through the sealing jaw, tunnel belt and outfeed, so the pack pattern, weight and product stability must be checked before a recommendation is made.
Typical sleeve sealer machine options
- Automatic sleeve sealers for repeated production runs and conveyor-fed lines.
- Semi-automatic sleeve sealers where an operator presents or collates the pack.
- Inline sleeve sealer layouts where the pack travels straight through the sealing and shrink tunnel route.
- Side-feed layouts where products need to be pushed or collated before entering the tunnel.
- PE film and shrink tunnel combinations for transit packs and multipacks.
Details needed before specifying a sleeve sealer
| Pack data | Product dimensions, weight, bundle count, lane layout and finished pack size. |
|---|---|
| Film route | Film type, film width, thickness, roll handling and required shrink finish. |
| Output target | Packs per minute, hours per shift, changeover frequency and manual handling points. |
| Line layout | Infeed height, conveyors, space, utilities and downstream packing equipment. |
