SML’s multi-purpose cast film line with new MDO unit
Austrian extrusion machinery maker SML says it has set up the newest version of its multi-purpose cast film line in its Technology Centre. The line is universally applicable and features a number of technical innovations, such as a further-developed MDO unit.
The cast film line is ready for the production of CPP, CPE, Cast-PET, barrier, as well as for mono-oriented films.
The application areas are comprehensive as well: ranging from film for metallised and laminated standard food and non-food packaging to easy-to-recycle stand-up pouches of MOPE film and further to label film, and also include technical products like cable insulations and easy-tear MOPP film.
Despite its wide functional range, the line can be further optimised for the manufacturing of specialised products.
“Our new multi-purpose cast film line will not fail to impress even long-serving experts. The line has the technical capacity to fulfil almost every customer requirement in cast film production,” Elias Mayrhofer, R&D Engineer at SML, commented.
“A central characteristic of all of our machinery is the coherent line concept that we continue to develop and optimise,” Mayrhofer states. This is underlined yet again by the modern and clear design of SML’s multi-purpose cast film line, which offers the following technical features:
- Five extruders for the processing of PP, PE, PA, PET, EVOH, as well as adhesives
- A seven-layer variable geometry feedblock with the possibility of numerous different layer arrangements
- Die width 2,850 mm, with internal deckling system two times 350 mm
- New MDO unit: maximum roll temperature of 160°C, maximum stretching ratio 1:10
- Horizontal sliding winder for up to four part bobbins
One key innovation featured in SML’s latest cast film line is the MDO unit, that is also designed for the manufacturing of easy-to-recycle mono-material films such as MOPP, MOPE and MOPET.
With this MDO unit, properties such as the film strength in the machine direction, stiffness and puncture resistance are increased even further, while the film thickness and elongation in the machine direction are significantly decreased, says SML.
SML has streamlined the whole MDO process: The clean and straightforward design makes operation comfortable and provides sufficient space for maintenance offering easy access.
Finally, all the process parameters of the MDO unit are digitally recorded and can be comfortably set and adjusted with SML’s new HMI.
SML’s new multi-purpose cast film line is available to customers for trials and sample production.
