The tape extrusion line is a critical stage in the manufacturing of rPET FIBC bags, enabling the production of high-strength woven fabric. Using advanced extrusion technology, recycled PET (rPET) flakes are melted, filtered, and extruded into a thin sheet, which is then precisely slit into narrow tapes.
These tapes pass through a controlled orientation process, where they are heated and drawn under regulated tension, aligning the polymer chains to enhance tensile strength, durability, and flexibility.
