applications in retail, lighting, interior architecture and transport, said the company. “We plan for Altuglas R-Life to be a growing, dynamic series – proven, with scientific tools such as LCA, to have a measurable environmental impact,” said Aldo Zanetti, global sustainability manager for engineered materials at Trinseo. For each solution, the Global Warming Potential
(GWP) was calculated through a life cycle analysis (LCA). There is a GWP reduction of 35% for the cast sheets and 53% for the extruded sheets. The sheets are processed to have equivalent mechanical, aesthetic, and optical properties of those made from an oil-based equivalent, said Trinseo. They are made at Trinseo’s plants in Rho in Italy, Saint-Avold in France, and Brondeslev in Denmark.
ECTFE protection A copper mining plant in Bulgaria has installed a protective lining – using laminated ECTFE sheets from Agru – in a 140m-high flue gas stack. Processing copper ores produces sulphurous waste gases, which are burned to generate energy. Sulphuric acid is extracted from the waste gases and
purified air is released via the flue gas stack. Because the sulphuric acid corrodes many plastics and metals, the company used a dual-laminate solution. This consists of the fluoroplastic ECTFE as lining material and glass fibre reinforced plastic (GFRP). The GFRP structure provides static and mechanical strength, while the ECTFE adds chemical resistance – and protects the GFRP. The application temperature of the flue gas stack is up to 70°C – and sometimes reaches 75°C. One challenge was producing sheet of the correct length for the customer. A roll length of 10m was

Optimize the presentation & creation of food packaging Consumers
Fogging most commonly occurs when there is a temperature difference. It can disturb the appearance of packed food. Van Meeuwen can assist you in creating clear sheet which is less sensitive for fogging. It will satisfy your customers and consumers.
Production process Too much friction of the plastic sheet can lead to process failures and loss of quality. Anti-blocking agents reduce this friction, making it easy to separate packages from each other. It also ensures that exactly one cup or tray is picked up at automated filling lines.
