The “New generation” of Colines air bubble lines

2019 is witnessing the launch of what is the "new generation" of extrusion lines for air bubble film by COLINES® S.p.A.

The starting point of the revolution introduced by COLINES is the twin screw extruder, not only capable of guaranteeing an effective 20% energy saving (tested on a line in regular production), but also enabling the user to process resin blends of not excellent quality as well as a high quantity of recycled material without compromising on the quality of the film.

Another crucial opportunity, when adopting a twin screw extruder, is the possibility to introduce mineral charges directly into the extruder, to produce high grammages with significantly reduced production costs

After a special restyling, the bubble forming calender can make very light films (below 30 gsm) at really high speeds (up to 120 m/min), without the need to use casting cylinders and avoiding the ovalization of the bubble.

Last but not least: the new lines offer the possibility to produce a range of films from 30 to 400 gsm while maintaining the option to install a third layer lamination unit (either in- or off-line), suitable also to laminate special products such as foam, again at notably high speeds.

Besides, thanks to the adoption of the newest technologies available in the industry, also the Duplex Plus winder can boast leading edge features, such as:

- extremely fast change cycle time: less than 50 seconds even with widths of more than 3000 mm;
- max winding diameter of 1600 mm;
- two versions available: winding with bubble on the inside, and with bubble on the outside
- fully automatic core loading system;
- automatic in line core cutting as option;
- automatic unloading system of the reel from the side or from the front, according to the room available;
- two cross cutting options: tapeless or with hot melt;
- coreless version available.
