The HPS4 INOX is a high-end automatic Flow Pack wrapper, built to wrap a wide range of products automatically with certain heat-sealing materials.

The machine is used for wrapping solid products individually, which, within the dimensions specified in the technical sheet, is necessary to protect them in a certain way from external agents.

Mechanical construction is robust and the operation versatile as it has electronic control of the different movements of the machine.

HPS4 INOX can work interchangeably with BOPP polypropylene, polyolefin or virtually any heat-sealable material or pressure. Can also work in vacuum with appropriate film and a vacuum unit subsequent inline.
