Automatic flow pack machines

FW Series

FW550S-LR - Flow pack machine with intermittent sealing and lower film reel

The new FW series of automatic packaging machines with flow pack system, designed according to Industry 4.0 and IoT (Internet of Things) technological platforms, is the family of machines that completes the SMIPACK range. This low speed version is equipped with a transversal sealing bar controlled by an intermittent motion servomotor. It is available in 4 models (two with upper reel and two with lower reel) and packs different types of items (even large-sized) in packages made up of simple or coupled flexible material with a maximum output of 40 products/minute. The film sealing and folding systems, combined with the dynamic and adjustable conformer, make these packaging machines the ideal solution for packing a wide range of long-life products (through injection of gas or nebulization of preservative flavorings) with different dimensions and heights, coming from several sectors.
