New advanced extrusion coating line ready at SML’s Technology Centre
A completely new production scale FlexPack extrusion coating and laminating line will be available from 3rd quarter 2023 onwards in SML’s Technology Centre. The line will be ready for performance tests, sample production and joint R&D projects with customers and partners.
The extrusion lines manufacturer’s FlexPack line comes in a new design and features various technical innovations. Equipped with three extruders, the plant is configured to process a huge variety of different polymers, ranging from polyolefins to TPU, TPE, PET, PLA and EVOH.
To increase the throughput for certain materials, the main extruder’s drive power had been raised to reach screw speeds up to 425 rpm. A Smart Drain unit supports fast and efficient polymer change overs. In addition, melt homogeneity can be observed via an Infrared Line Scanner that constantly measures the temperature profile in the melt curtain.
The co-extrusion feedblock provides up to five layers, which enables the production of barrier-coated film for flexible packaging. Apart from two automatic unwinds, the new line is equipped with an additional single unwind for the production of reinforced laminates. Fitted with the patented DoubleCoat technology, the plant is also suitable for creating ultra-thin breathable membranes.
Manufacturers of laminates, membranes and composites frequently use the demonstration lines in SML’s Technology Centre when they develop new products or optimize production processes.
