Useful next step for comparing L sealers, shrink tunnels, film route and quotation requirements.
Specification guide
The correct L sealer size is driven by the largest pack you need to wrap, the film centre-fold width, the sealing aperture and the shrink tunnel opening. This guide helps buyers prepare the measurements Lancing UK needs before specifying a machine.

The correct L sealer size is driven by the largest pack you need to wrap, the film centre-fold width, the sealing aperture and the shrink tunnel opening. This guide helps buyers prepare the measurements Lancing UK needs before specifying a machine.
Measure the product length, width and height after any tray, sleeve, carton or label has been applied. The largest pack controls the sealing aperture and film width. Small variations matter because shrink film needs clearance around the product before it enters the tunnel.
The pack must travel smoothly through the film folding, sealing and transfer area. A very tight fit can increase jams, poor seals and film drag. It is better to confirm the full size range than to size the machine only from a brochure dimension.
A good seal is only part of the result. The tunnel must be wide enough, high enough and long enough to shrink the film cleanly at the desired output speed.

FAQ
Usually yes, provided every product fits inside the machine aperture and available film widths. Changeover and settings should be checked.
