SHOW PREVIEW | PLAST
Blown film workshops Bandera will run a series of workshops at its plant in Busto Arsizio – not far from the Fiera Milano – for the duration of the show. Here, it will demonstrate a blown film co-extru-
sion line, as well as thermoforming equipment. At its headquarters it will run a newly manufac-
tured blown film extrusion line, of the five-layer polyolefin-dedicated PO5 series, which has hourly outputs of more than 1,000kg, and a useful film width of 2,600mm. In addition, it will show a full extrusion line for

tory 4.0 will be featured on touchscreens. Winen- ergy is the energy use monitoring and analysis system comprising proprietary software that is connected to a series of measuring devices – which acquire data about a variety of physical parameters including power, electricity, thermal energy and temperature. It can be installed on its own or in combination with Winfactory 4.0, to maximise system control and efficiency. Piovan will also show its Quantum E gravimetric
batch blender with continuous extrusion control, and demonstrate a system with a Pureflo filterless granule receiver, Modula series auto-adaptive drying system, and Quantum Q7 batch blender for medical applications.
Film demonstration Macchi will display and run a five-layer POD line which has been engineered to produce films for applications such as lamination, heat shrink, stretch and silage with high quality and productivity. Through close cooperation with Dow Chemical – which has developed a number of material formu- lations with Macchi’s technical department – the five-layer POD blown film line on display will run faster than 1000kg/h, despite the venue putting a restriction on the height of the tower. Nearby, Macchi will host a Siemens information point where its German partner will give visitors the chance to investigate the implementation of Industry 4.0 systems. There will also be a new line management software developed by Macchi’s IT department.

rigid PET, PP and PLA film, with a gross output of 1,200kg/h, useful film width of 1,450mm and thickness range of 0.14-1.5mm. There will also be a range of machinery for agricultural and geo-liner blown film, for both civil and industrial waterproofing applications. At the same time, Bandera will show a new Pure unit, for the production of FDA/EFSA-approved rigid packaging films, using post-consumer recycled PET. Bandera will provide shuttle buses for the 15-minute journey to Busto Arsizio.
Drying on demand At Plast, Moretto will show its Eureka Plus drying system – which combines four patented technolo- gies in a single system. The four technologies are: n Moisture Meter Manager – an in-line polymer moisture measuring system that manages the drying process based on actual needs of the process;
n X Max – a multi-bed dryer with consistent dewpoint;
n Flowmatik – a dynamic airflow management device; and,
n OTX – a series of drying hoppers with high mass flow drying characteristics. Moisture Meter Manager measures each
granule’s residual moisture (in ppm) in-line – and applies the data to an adaptive drying system. It consists of the devices MM Box and MM Crown. The double control of the granule’s moisture content at the hopper’s input (through MM Box) and output (through MM Crown), allows the system to manage the dryer’s work conditions by maximis- ing process performances. Power-Peak technology – which measures the dielectric characteristics of the granule – boosts the system’s measurement capability, says Moretto. Moisture Meter Manager creates ‘on demand dry-
ing’, says Moretto, as it focuses on the real drying needs of the polymer at any given time and man- ages drying in response to internal and external variables – which interfere with moisture levels.
