Brazilian film producer installs second Macro cling PVC line
Macro Engineering and Technology has installed a second cling PVC cast film extrusion line at Meiwa Embal- agens in Brazil, which makes polymer film for the food packaging industry.
“Meiwa was happy with its
first cling PVC cast film line, but wanted to tweak the second line for some specific requirements,” said Jim Stobie, CEO of Macro Engi- neering. “We can custom- engineer all our lines to suit different customer needs, so were happy to accommodate Meiwa’s requests.” This new cling PVC cast film
line can produce thicknesses in the range of 8-16 microns, with a die width of 2.2 meters. The winder can produce 4 ups
DRYERS
Adaptive dryers use smart control to minimise energy consumption
Motan Colortronic has launched a new line of EMA fully adaptive smart dryers. The new mobile single- hopper unit builds on the ETA Plus technology that Motan uses on central drying systems with multiple hoppers. The EMA dryers are designed to offer consistently low dewpoint air to a drying bin of 60, 100 and 150 litres, while minimising energy consump- tion. They are available with fully automatic air flow control, which saves further energy and automatically creates an
48
anti-stress system for the material, says Motan. The units can be supplied
with single conveying units or a mini central system built in to the dryer, ensuring high flexibility. The touch screen control is
compact and easy to use, whilst the solid state relays and high quality parts ensure optimum reliability, says the company. The control can be connected to a Motan Colortronic control report and VisuNet. ❙

Bandera of Italy has strengthened its presence in the Egyptian market by selling a SmartFlex 22 Plus blown film line to a local producer of agricultural film. The line will be used to
across the web at a line speed of 250m/min. “We wanted a partner that
would provide consistent quality, have good after-sales service, and tailor the equipment to our needs,” said Ricardo Huang, director of Meiwa Embalagens. “We did
not want an off-the-shelf line that everyone else has, we have some unique require- ments”. As well as the two PVC cling film lines, Meiwa uses another line from Macro to produce polystyrene foam. ❙

make both agricultural and packaging film. It has a lay-flat of up to 2200mm net (already trimmed), and produces film in a thickness range of 20-200 microns. Output is up to 550kg/hour. The line includes one
extruder with a diameter of 85mm, which is used to produce the core layer, and 2 extruders of 65mm diameter for side layers. There is also a three-layer co-extrusion die head with 600mm diameter die and internal bubble control (IBC) system. At the same time, there is a 12-component batch dosing system. Four ultrasound sensors
are responsible for IBC management and automatic width control. Other features include: a high efficiency, dual lip air cooling ring; an automatic film thickness measuring and adjusting system; bubble guiding cage; rotating haul-off using aluminium rollers, with 2400mm wide roller face; and additional ‘S-wrap’ cooling cylinders and gusseting boards. The line is also capable of
Internet of Extrusion/Industry 4.0 connectivity and manage- ment via PLC, according to Bandera. ❙
