Shrinkwrappers machines

​

The LSK series is composed of automatic shrink wrap machines to pack plastic, metal, cardboard or glass containers. Depending on the model chosen, they can make packs in film only, cardboard pad + film, cardboard tray, cardboard tray + film. 

LSK series packers achieve an output rate up to 40 packs per minute, according to the machine model and the type of product to be handled. The pack collations can vary according to the containers shape, capacity and size; the most requested collations are: 2x2, 3x2, 4x3 and 6x4. 

All LSK machines are equipped with a mechanical product grouping system and are supplied with an in-line or a 90° infeed conveyour, depending on the customer’s exigencies. The change-over is manual.

The shrink tunnel features state-of-the-art technical solutions reducing energy consumption and ensuring an eco-friendly working process. The tunnel conveyor belt is made up of fibreglass bars, driven by side chains (®SMI). Thanks to the precise analysis of thermodynamic phenomena generated by the shrink process, the tunnel distributes hot air flows in an efficient and homogeneous way on the pack, thus ensuring its excellent quality at the end of the process. Shrink resistances are positioned on the side walls of the tunnel; the lubrication system is automatic and centralized (optional for SK 400 models).
