New generation for stretch film

At K 2013, Colines introduced the new ALLrollEX 1500 line for the production of stretch film, to be considered, according to the Italian manufacturer, as the evolution of a major success, HANDrollEX 1000 mm. The in-line direct production of manual reels became a reality thanks to the very quick and impressive diffusion of this model, with tens of lines sold all over the world.
The same salient features (flexibility and user-friendly characteristics, very high relative productivity, limited initial investment, low energy consumption, reduced space requirement) were given a further boost in the new generation of ALLrollEX 1500, expressly engineered for the production of thin films on high standard manual, automatic and jumbo reels, without any tails or sacrifice in the performance.
Particular emphasis was put on the capacity to wind very thin films (up to 6 micron) on reels without stressing - and consequently damaging - the film thanks to a tension control system specifically designed for such low thicknesses; the same attention was given to the study of the winding axis, equipped with a pressure control system to avoid any air absorption in the reel.
Not just the new winder but the whole line has actually been designed to ensure energy saving and flexibility of use. It features: torque motors for extruders and chill-roll, allowing over 10% saving in energy consumption compared to the traditional motor + gearbox solution; infrared heaters for extruders, with an actual energy saving of more than 20% compared to the traditional ceramic solution; melt pipe insulation, minimizing thermic Energy waste and environmental impact; infrared reflection thickness gauge system, allowing the film gauging directly in contrast on the chill-roll, dramatically decreasing the response time of the system and significantly reducing production waste for the line start-up until the system reaches full operational speed; extruders with a high L/D ratio and high speed, to guarantee the perfect blending of raw materials even when they are not "perfectly compatible" for blending, and ensuring a high productivity at the same time.
