LF-800-COEX Multilayer Film Blowing Line
with Batch Blender and Multi-Station Hopper Loader
The most recent LF-800-COEX film blowing line, built for DOW Chemical/ India, features an automatic resin blending system where up to four different resins can be blended with a very high accuracy. The resins are weighed individually and then led into a blender and further down into a container. All extruders have our loss in weight feeders and the upper hopper on each unit is equipped with a vacuum loader, which will suction the resin blends from the storage container. The amount of resins fed into each extruder is determined from the loss in weight feeder and the vacuum hopper loaders will automatically refill the LIW feeders
Included in the line are modular downstream processing stations such as a customizable collapsing frame, haul-off nip rolls, film edge trimmers, corona treatment station, and two-station surface winder.
