The topics covered on SML Innovation Days were varied and diverse; they ranged from new technologies for recyclable, flexible packaging to innovative stretch film products, and from coating lines for liquid packaging board to solutions for data-based process optimisation.
“The Innovation days were a perfect opportunity to show the outstanding technical capabilities of SML to a range of high-ranking industry experts. In the relaxed and inspiring atmosphere of our headquarters, we discussed the latest developments in our industry face to face and let our visitors experience state-of-the-art extrusion technology live in operation up close,” Karl Stöger, CEO of SML states.
Cast film technology:
Revolutionising mono-material packaging: MDO-PE film as thin as 15 µm
The innovative cast film line was designed to manufacture MDO-PE film as a substitute for BOPET film. Naturally, film production takes place in an absolutely stable process, and with no compromises in performance, functionality and printability. A thickness range from ultra-thin 15 µm to 60 µm, production speeds up to 300 m/min, a perfect thickness profile across the entire film width, and the possibility to manufacture various mono-material PE film types are the main advantages of SML’s latest cast film line with an integrated MDO unit.
Extrusion coating and laminating:
Live Demonstration: Manufacturing mono-material PE structure for stand-up pouches
A highlight at the SML Innovation Days 2024 was the live production of films for easy-to-recycle mono-material stand-up pouches from PE. A highly innovative MDO-PE film for the surface layer and a CPE sealant film were laminated on a high-performance FlexPack coating and lamination system.
Cast stretch film technology:
World premier: Inline pre-stretch production live
For the first time, SML presented its inline pre-stretch unit live in operation to a wider public. Integrated in a state-of-the art SmartCast Infinity stretch wrap film line, the system is setting a new standard for efficiency at production speeds of up to 850 m/min. With the integrated pre-stretch unit, ready-to-sell-products can be manufactured straight from the line. At the end, the inline manufacturing of pre-stretch film means significantly lower production efforts, less space requirements and logistics.
SML EcoCompact II: High-speed winding at 2-metre-wide stretch film line
Live demonstration runs were also performed with an EcoCompact II stretch film line. Visitor interest centred on the high-performance winder W4000-4S 2T. Its short winding shafts make significantly higher production speeds possible. Even for hand rolls on 2-inch cores, production speed can be extended to 800m/min and more, leading to a significant increase in output - and line efficiency.
