Shrink Packaging Machines
L-bar, side-seal and sleeve wrappers with shrink tunnels for retail packs and multipacks.
Also called shrink wrappers, L-sealers, sleeve wrappers and shrink tunnels.
What these machines do
Shrink film gives a tight, tamper-evident wrap around a single product or bundles several into a multipack that needs no tray. Machines range from one-step chamber units to continuous side-sealers and bottle bundlers.
The product is enveloped in centre-folded or flat film and the open edges are sealed by a hot knife or impulse wire. In the tunnel, recirculated hot air shrinks the film evenly around the product. Polyolefin is used for retail display packs; polyethylene for heavier transit bundles.
Typical options
- Automatic collating infeed

Process sequence
Infeed
Products are spaced or collated into the pack pattern.
Wrap
Film is drawn around the product from one or two reels.
Seal
An L-bar, side-seal or cross-seal jaw closes and trims the film.
Shrink
The tunnel heats the film to its shrink temperature.
Cool
A cooling fan sets the film before discharge.
