EPE Banana Bag Extrusion Line

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. 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. key Applications: 1. To keep warmth of banana to insure quick growing. 2. To protect against insects and birds.I.
