Hello,

I m burak başdağ , I worked in a factory about producing BOPP(biaxially oriented polypropylene). We use thin screw extruder and in during production sometimes we encounter with ''O'' hole in streched film. It is happening not so much but, it is important continuous process. Capacity for one day 200 tones.

May be reason thin screw ekstruder?

is there any person to share his/her ideas with me and help us for brain storming for short time

thanks

BOPP Production Engineer.
