The COMBO is a heated packaging machine that is composed of different modules, each of which has a different sized polyethylene shrink film reel. When a package is placed on the conveyor belt or conveyor table, the machine automatically detects its size and directs it to the module with the most suitable film reel for its dimensions. The product is wrapped with the shrink film and directed to the shrink tunnel, where heat is applied and we obtain a completely packaged product protected from external agents. Immediately afterwards, a package with other dimensions can start this process without having to stop the machine to change the film reel.
