Tape Stretching Line

The tape stretching line is a critical stage in the manufacturing of FIBC bags, ensuring the production of high-strength woven fabric. Using state-of-the-art extrusion technology, recycled PET (rPET) resin is melted and extruded into a continuous sheet, which is then precisely cut into fine tapes. These tapes undergo a biaxial stretching process, where they are elongated under controlled temperature and tension, enhancing their tensile strength, flexibility, and durability. The process is optimised through automatic width control, gravimetric dosing systems, and advanced IR heating zones, ensuring uniform stretching and high molecular orientation for superior mechanical properties.

The tape stretching lines feature energy-efficient drying systems, high-speed winding units, and online quality monitoring, allowing for consistent tape thickness, uniform denier, and excellent adhesion properties. The tapes are subjected to annealing, which stabilises the material’s structure, ensuring long-term form stability in FIBC bags. These advanced lines also integrate UV stabilisation treatments, providing resistance against prolonged exposure to sunlight, crucial for bulk handling applications in outdoor storage conditions. The result is a high-performance fabric tape with exceptional strength-to-weight ratio, optimised for further processing in circular looms.
