Box and carton packaging

L sealer for boxes

Boxes and cartons are one of the strongest applications for L sealer machinery because they are usually stable, regular in shape and suited to a tight presentation shrink wrap after the heat tunnel.

Box dimensions drive the specification

The largest box size determines the seal aperture, tunnel opening and film width. Allow for tolerance, label height, slight carton bowing and any future product sizes.

Clean finished wrap for retail boxes
Good fit for regular carton shapes
Film width matched to largest pack
Tunnel settings tuned for neat corners

Presentation shrink versus transit shrink

Individual boxes normally suit POF film and an L sealer. Heavier trays or transit bundles may suit PE film and sleeve sealing instead.

Common box applications

Retail cartons, gift packs, printed matter, phone boxes, small electronics, cosmetics, stationery and kits can often be reviewed for an L sealer route.
