RV4 INOX Flow Wrapper

RV4 INOX Flow Wrapper

The RV4 INOX Flow wrapper is an automatic Flow Pack type wrapper, built to wrap a wide range of product automatically with heat-sealing materials.

One of the characteristics of this machine is that it can work indistinctly with BOPP polypropylene films, shrink polyolefins and complex and barrier films without making mechanical adaptations.

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

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