COLINES® is proud to introduce
the launch of the new Polyblown® 5-layer POD series (which
stands for Polyolefin Dedicated), designed for the production of polyolefin
films and suitable for processing post-consumer recycled (PCR) resins. The
production line has been recently redesigned and optimized, and during the
last week of July, it was showcased with a dedicated event for some selected
customers, allowing them to appreciate its performance.
Particularly noteworthy are the remarkably low
specific energy consumption rates, ranging from 0.32 to 0.38 kWh/kg
(depending on the formulations), significantly lower than the industry
average. These results have been achieved through the use of infrared
resistors and specific extrusion group design.
Other
notable features include:
-
Immediate and user-friendly graphical interface of the software.
-
Excellent control of film tension and winding speed, achieved with the use of
brushless motors.
-
Sturdiness, modularity, dedicated design, and ergonomics.
-
Extremely low thickness tolerances.
-
High production capacities.

Thickness tolerances: 2.5-3%.
Silobags: 230 microns thick, 5 meters circumference.
Production rate: 650-750 kg/h depending on the formats.
Energy consumption: 0.32-0.35 kWh/kg.
Thickness tolerances: 3-3.5%.
Agristretch Film: 25 microns thick, multirolls with 2000mm layflat width.
Production rate: 400-500 kg/h depending on the formats.
Energy consumption: 0.33-0.38 kWh/kg.
Thickness tolerances: 3.5-4%.
Collation Shrink Film: 50 microns thick, multirolls with 2500mm layflat
width.
Production rate: 700-800 kg/h depending on the formats.

Thickness tolerance: 2.5-3%.
During
the upcoming Plast trade fair from September 5th to 8th, 2023, the production
line will be in operation, and customers will have the opportunity to observe
it live at our Marano Ticino facility. (Book your spot now at plast2023@colines.it).
