Automatic flow pack machines

FW Series

FW550S-LR SERVO - Flow pack machine with box motion 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 medium-high speed version is composed of 4 models (two with upper reel and two with lower reel) and stands out for the presence of a cross sealing bar with box motion system, both controlled by servomotors. The translating movement allows to pack a wide variety of long-life products (through injection of gas or nebulization of preservative flavorings) with different sizes and heights, without machine downtime, in packages made with simple or coupled flexible material. The film sealing and folding systems, combined with the dynamic and adjustable conformer, make process regulation versatile and fast on the FW models. These packaging machines can reach the maximum output of 80 products/minute.
