Higher plant efficiency for sustainable film production, less energy consumption, and less production waste are the highlights of Brückner Maschinenbau's exhibit this year.

In the fight against climate change, it will not be possible to do without plastic packaging that is produced in a way that conserves resources in the foreseeable future. That is why Brückner Maschinenbau is sticking to its ambitious goals for further increasing efficiency in film production in addition to the developments for the rapidly developing circular economy. This means decreasing raw material use, ever lower energy consumption and "zero waste" in film production.

Faster and wider BO plants

The more efficient and higher output a film stretching line is, the lower the specific energy consumption. These parameters can mainly be influenced by the line speed and the line width.

 

BOPP and BOPET

In the production of the two most popular packaging films, BOPP and BOPET, the benchmark in production speed has so far been around 600m/min. At K 2022, Brückner Maschinenbau is presenting it new line concepts with significantly higher running speeds.

 

BOPA

BO films made of polyamide are particularly suitable for packaging oily, fatty foods and for frozen foods. The demand for this is continuously increasing and with it the demand for corresponding film stretching lines.

 

At K, Brückner Maschinenbau presents new line types with up to 80% more output – based on an increase in production speed from 220m/min to 350m/min and a line widening from 6.6m to 7.4m.

 

Battery separator foils and capacitor foils

In these segments, the previous (already exclusive) line width of 5.5m is being increased step by step to over 6m and the associated increase in output of over 20%. In addition, both the sequential and the simultaneous stretching technology for capacitor films were further developed: the focus was on higher film yield and optimised film properties, especially for films in the 2 µm range.

 

Technical innovations for more sustainability in film production

 

Direct recycling

Thanks to a new type of "direct fluff Ddosing", the edge trimmings and waste produced during production can be directly fed back into the extrusion process in a higher percentage – without any prior re-granulation process. This saves energy, conserves raw material and comes very close to the goal of "zero waste" in production.

 

Intelligent stretching oven management

Instead of the heat exchangers previously used for heat recovery, a patented, energy-efficient oven control system across all temperature zones of the stretching oven now ensures an energy saving of around 200 kW per year.

 

Aerodynamic zone separation

The patented process guarantees even better and more uniform film quality across the entire working width and for ever higher production speeds. This increases the proportion of A-grade film on the winder, reduces production waste and lowers specific energy consumption. 

 

Brückner Maschinenbau GmbH & Co. KG, the world market leader for film stretching equipment, is part of the Brückner Group in Siegsdorf, Upper Bavaria, a family-owned, medium-sized group of companies with a total of more than 2,600 employees at 23 locations. Other members of the group are the service provider for film stretching technology, Brückner Servtec GmbH, Kiefel GmbH, one of the leading manufacturers of machines for plastics processing, and the Swiss PackSys Global AG, a globally renowned manufacturer of state-of-the-art packaging machines.
