The SmartCast stretch film line (6-up) is one of the most versatile stretch film lines within SML’s portfolio. The concept features the greatest variety of equipment options for unparalleled and efficient stretch film production – from 2-inch hand rolls to high-quality machine rolls, 60 kg-jumbo rolls, and films with folded edges, among others. At the K trade fair, SML unveils the next generation of its SmartCast brand and presents innovations in both line design and product quality.  

New extruder arrangement – simplified maintenance 
Next to an overall face-lift, the new 3 m line concept boasts an ultra-compact footprint with newly arranged, parallel-oriented extruders. This arrangement places all motors, dosing units, and filters next to each other, facilitating faster and easier access for maintenance and service. Pre-assembled extruder modules further streamline the installation process. In addition, all small electrical components are now housed in an E-container, which eliminates connection boxes in the hot areas of the extruder.  

Chill roll with even larger diameter and new surface 
The SmartCast is equipped with the largest chill roll ever seen in the stretch film market. With a diameter of 1,800 mm and the latest chrome-plated Smart 3.0 surface, this chill roll sets a new standard in the production of high-quality stretch film. The Smart 3.0 surface finish significantly reduces cleaning efforts for paraffin and other deposits that occur during production. The extended contact area at the chill roll allows for gentle cooling, which results in the highest elongation combined with superior tear propagation. Despite its size, it still offers the fastest cooling for SuperStiff products. 

Coreless winding to save resources 
ith the new SmartCast design, SML has further developed its coreless winding technology not only to improve production economy but also to save resources and improve sustainability. SML’s coreless technology improves the winding quality on the inside of the stretch film roll at optimised production speeds. Post-production shrinkage is reduced. But most importantly, quick switches between coreless winding and winding on rigid cores are achieved at the touch of a button. This unique key feature reduces waste to zero during changeover and maximises production efficiency. 

To sum up, the new 6-up SmartCast stretch film line represents a significant leap forward in efficiency, product quality, and sustainability. Its innovative design and advanced features make it a must-see at the K 2025 trade show, where it will be demonstrated live in operation on the SML booth.
