Large carton shrink wrapping

Shrink wrap machine for large cartons

Large cartons need careful review because aperture, film width, tunnel opening and product stability all become more critical. A machine that suits small boxes may not transfer large cartons cleanly.

Shrink wrap machine for large cartons guidance from Lancing UK.

Aperture and clearance

The sealer and tunnel must allow the largest carton to pass without catching the film or product. Future product sizes should be included in the review.

Check maximum carton size first
Match film width to large packs
Review tunnel aperture and airflow
Consider conveyor support for heavy cartons

Film width and waste

Large cartons can require wider film. Too much film can create loose corners, while too little can cause seal failure.

Tunnel performance

Large packs need enough heat exposure across the full surface. Tunnel length, airflow and belt speed become especially important.
