Latest advances in stretch film production

Building on the success of previous generations of SmartCast stretch film lines, SML has now installed the fourth generation of the SmartCast Infinity in its Technology Centre, equipped with the latest advancements: a newly developed nanolayer feedblock for 101 layers.

Nanolayer technology is an advanced technology in stretch film production to improve film quality and wrapping application. Nano-layered film gives stretch film incredible performance despite its thickness. While Nano67 is already an established technology for high-end applications on the market, SML now pushes this technology further.

What makes Nano101 unique?

In close collaboration with Cloeren and drawing on the vast experience and learnings of Nano67, we developed a truly unique piece of equipment. The new nanolayer feedblock was custom-engineered to meet highest requirements. This design differs from every previous solution in three key ways:

• 101 layers – the highest number count ever achieved in stretch film
• Highest percentage of nano-structured film in the total film
• Highest number of extruders – the nanolayer feedblock is fed by eight extruders

Overall, these features offer higher flexibility to influence film properties. “Nano101 lets us combine a wider range of functional materials, in different sequences and at lower percentages. While the stretch films produced on our machinery already exceed the market requirements for elongation, Nano101 focuses on influencing tear propagation, holding force and puncture resistance,” explains Thomas Rauscher, Product Manager at SML.

With Nano101, SML now offers two innovative nanolayer technologies as standard: the time-proven Nano67 and the brand-new Nano101 – the choice is yours!
