SML is to present its recent high-performance extrusion solutions and takes customer’s production to new levels:
March 26, 2019Triplex extrusion laminating line: refines complexity into simplicity
The precise interaction between different unwinding units and three laminators, managing very different materials like paper, board and aluminium, is one of the essential characteristic of SML’s new triplex extrusion lamination line for aseptic board packaging in one simple and cost-effective process. The complex line is characterised by an elaborated setup, which is combining durable machine design, proven components and the latest state-of-the-art technology with a maximum of operator convenience and production efficiency. With the newly introduced automation system in combination with a powerful data logging system it is giving maximum traceability and quality control to the end user – making the machine ready for the challenge of industry 4.0
MDO units for greater flexibility and excellent film results
Based on decades of experience SML has designed a new mono-axial direction orientation unit which offers greater flexibility in terms of processing a huge variety of different film types and structures in large film widths. Its main advantage lies in its ability to control film properties through the inline variation of the stretching gap between 70 and 350mm using a servomotor. This is significant because the best PP and PE film characteristics result with a shorter gap, while a longer gap is required when stretching PET film. Excellent results are guaranteed in terms of improved visual qualities, achieved tenacity, increased barrier properties and reduced film thickness. And not to forget the breathability for hygiene applications.
In short, stretching using SML’s innovative MDO technology means higher production speeds and output in combination with process flexibility and excellent film properties.
PET sheet lines and the choice of three extrusion concepts
SML’s third focus is on its extrusion concepts for PET/rPET sheet production.
Due to SMLs vast experience in PET extrusion, SML assist its customers in the selection of the best extrusion system for their application and available feedstock: single-screw extrusion with pre-drying, recycling extruder or conical twin-screw extruder. No matter which high-peformance solution is used, they mean moderate capital expenditure, along with high output, reduced energy consumption, ease of operation and minimised need for maintenance.
