The HPN 4 INOX is an automatic Flow Pack wrapper, built to pack a wide range of products automatically with heat-sealing materials.

The machine is used for wrapping solid products individually, which, within the dimensions specified in the technical data sheet, require protection from external agents and allows it to work both vacuum (with a subsequent vacuum unit) and shrink-wrapping, with the appropriate film and a shrink tunnel.

The mechanical construction is robust and the operation versatile since HPN4 INOX has electronic control of the different movements of the machine.
