Why Do The Stretch Film Extruding Machine Produce Black Spots, How To Deal With It?

The black spots on the film produced by the stretch film extruding machine may be added back or other unclean materials. Then, after the substances are degraded, they cannot be fully melted into a film. When they come out, there will be black spots or fat spots. The time is high-temperature carbonization, and it is necessary to change the net for such materials. If it is multi-layer co-extrusion, it can use special cleaning materials for carbon deposition.
