Box and carton shrink wrapping
Boxes and cartons are among the most common products for L-sealer machinery because they are usually stable, regular in shape and suitable for a neat presentation shrink wrap. The correct machine depends on the largest box size, the required finish, the film width and whether the pack is handled manually or automatically.

Typical applications include cosmetics boxes, printed cartons, electronics boxes, books, stationery kits, pharmaceutical cartons and retail presentation packs. For fragile packs, product spacing and transfer into the tunnel are important because loose film can catch if the pack is unstable.
Measure the largest box in millimetres and provide the expected packs per minute, film preference, power supply and a photograph or sample of the product. This allows the machine aperture, film width and tunnel length to be checked properly.
For a reliable recommendation, send product dimensions, photographs, required output, film preference, available floor space, power and compressed air details. Lancing UK can then check the correct machine aperture, heat tunnel size, conveyor layout and operator access before quoting.
FAQ
Boxes are commonly shrink wrapped using an L sealer and a heat shrink tunnel. The L sealer creates the bag and seal, while the tunnel shrinks the film.
Often yes, as long as the pack dimensions and film requirements are within the machine specification.
Semi automatic is useful for lower volumes and varied products; automatic is better for repeat production and higher throughput.
