So the added price is very litter and a small air compressor is included. The popular width range is 700 - 1000 mm at thickness of 0.25 - 0.8 mm.
So we usually give design for both open sheet and tubular sheet.

For tubular EPE banana bag extrusion, it is basically our standard sheet extrusion design + a compressed air filling system. No slitting. Winding is by folded way. Just like the theory of Film Blowing Machine.
