Smart Automation and Eco Focused Engineering Improve Film Line Efficiency
The Greenline concept for BO systems aims to maximize efficiency. The core elements are
- Solutions for PCR use: After years of R&D projects, with the aim of significantly increasing the proportion of recycled polypropylene in the production process for BOPP films, a milestone has been reached in close cooperation with the entire value chain to further close the loop for BOPP films.
- Direct fluff dosing: Higher production/material efficiency with an advanced solution to increase direct fluff dosing. New software solutions now allow the maximum possible amount of production waste to be fed inline into the BO process at any given time. This also reduces energy consumption as this waste does not have to be re-granulat
- Heat recovery unit 2.0: This solution maximizes energy efficiency and significantly reduces operating costs by capturing and reusing waste heat more effectively than ever before. The energy-rich exhaust air is fed into the heat recovery unit, where thermal energy is transferred to the fresh air drawn in via a special heat transfer medium.
- Exhaust air purification system integrated into the BO process from a single source and ideally coordinated. In the first stage, the exhaust air is cleaned using a scrubber; in the second stage, gaseous hydrocarbons are separated from the exhaust air using an electrostatic precipitator.
- High-temperature heat pump to improve waste heat recovery. This patented solution uses waste heat after passive heat recovery at a low energy level and raises it to a usable energy level. This reduces operating costs and significantly improves the CO2 balance.
- 12m line concept: Increased productivity and efficiency for the lowest specific energy consumption.
Digitalization: Standard Data Interface (SDI)
Plug-and-play connection of Brückner stretching lines to the customer’s own IT systems. The benefits:
- Seamless integration of plant data into customer systems such as dashboards, production planning or ERP using a simple and efficient connection.
- Reduced complexity thanks to simplified IT architecture with just a single interface to all relevant data from a Brückner film stretching line.
- Fast implementation of data and protocols by using the OPC UA standard.
- High reliability: Elimination of potential sources of error by standardizing the protocol and the data read out.
- Availability for every stretching line generation: Simple upgrade for older lines by Brückner Servtec.
- The standard also allows the connection of lines from other manufacturers.
New solutions for the production of technical films
- Lines for battery separator films with 8.7 m usable film width: the widest separator film lines in the world with an annual output of up to 500 million m² and with consistent film quality
- Sequential and simultaneous lines for capacitor films and current collector films with a line width of up to 8.4 m for EV applications or films with high energy density for renewable energy applications in the energy industry
- Extremely thin films down to 2 microns
