attach importance to highest optical film properties.
Maximum transparency through rapid cooling.
With EVO Aqua Cool you produce highly transparent film thanks to the quick water cooling effect, as the crystallization of the melt is strongly inhibited or even prevented. Further benefits: high gloss, extreme puncture and tear resistance as well as best thermoforming properties.
What is the difference between conventional blown film lines and EVO Aqua Cool? Following the force of gravity of water, the extrusion direction is reversed - vertically from top to bottom. The film tube is inflated to the desired diameter and then quickly cooled down by water running down the bubble, thus creating the special optical and mechanical film properties. The water is then removed from the film with the help of negative pressure (vacuum). Our optional Ultra Flat or Ultra Stretch features allow you to optimize stiffness, barrier function or flatness during further processing - without compromising transparency and formability.
Automatic bubble profile control and water-vacuum calibration ensure a stable process.
Excellent transparency, gloss, puncture resistance and thermoformability for demanding applications such as food packaging or medical infusion bags.
Due to the particularly high performance of the individual film layers, they can be designed thinner. This saves you valuable raw material. Furthermore, cheaper raw materials can be used (e.g. homopolymers instead of expensive copolymers).

Increase performance? Optimize film properties? Reduce manufacturing costs? With our Ultra Features you get the best out of your line.
No more bagginess or camber: With our EVO Ultra Flat take-off, you simply produce perfectly flat film - energy-efficient with moderate stretching of a few percent. This speeds up subsequent printing and lamination processes and saves adhesive and printing ink.
The perfect combination of moderate stretching for film flattening and stretching up to 100 percent to enhance specific mechanical properties - depending on the desired application. You can achieve both with our EVO Ultra Flat Plus stretching unit in perfection and with high energy efficiency.
Produce fully recyclable packaging films based on PE mono-material. With our EVO Ultra Stretch stretching unit, you can reach a new level with maximum stretching of up to 1:10. Improve the mechanical properties of your film. Achieve the same function as PET films with standard PE films, as an example. Thus you can replace PE/PET with PE/PE mono composites for 100 percent recyclability.
*Can also be used as EVO Ultra Flat.
For high transparency, formability and puncture resistance, water-cooled film is unbeatable. With our EVO Ultra Quench high performance water cooling and calibration unit you get maximum process stability with low energy and water consumption.
Process all raw materials. Our EVO Ultra extruders combine maximum flexibility with high throughput. The wide temperature range from 20 to 250°C in the feed zone makes it possible.
Achieve ideal film flattening easily and quickly. With our automatic flatness measurement you can adjust your EVO Ultra Flat stretching unit comfortably and reproducibly via HMI input. The laser-supported inline measurement reliably determines the measured flatness value and takes over the precise adjustment of all parameters.
