Blown film extrusion line for agricultural film
500 - 1 000 kg/hr Davis Standard Extrusion Systems

Davis-Standard Converting Systems leads the industry in experience and technology innovation on large, wide blown film systems. There is no better extruder available for high output and low melt temperature than the MAC extruder and DSBII screw. The unique extrusion concept leads to the best and most consistent melt quality (temperature uniformity to 2 degrees F and pressure variation <1%) which is necessary to get uniformity from large dies. The die systems can be oscillating up to 1.2 M diameter or stationary up to 2.1M diameter. These systems produce controlled property films at wide widths with flat rolls.

Super Air Cooled MAC extruders utilize the single high volume suction blower concept for cooling. Low maintenance.
DSB II screws in special diameters of 130 mm, 150mm, 165mm, 200mm and 220mm provide uniform high output of LLD/LD/HD/EVA blends. Best MD variation in industry.
Centrex dies allow for easy operator access and excellent uniformity to <5% before auto adjustment.
WesJet air rings and IBC provide high cooling rates and increased bubble stability.
WesJet air rings cut the gauge variation in half.
Collapsing frames can be wood, covered slats or roller with partial of full gussets.
Folding and Unfolding.
Winders can be shafted or shaftless.
Small roll winders available with automation.
