Applications
KUNLUN PP S1003 serves the woven packaging industry as a primary resin for flat yarn extrusion. Woven bag manufacturers rely on the 35.1 MPa tensile yield strength to produce tapes that hold up under heavy filling loads. A high isotactic index of 98.5% ensures tight polymer chain alignment during the drawing and orientation process, maximizing tape tenacity and reducing breakage on circular looms.
Jumbo bag and FIBC producers require a resin that maintains dimensional stability across large fabric panels. The 1.48 GPa flexural modulus gives the woven fabric enough stiffness to hold its shape when filled with bulk materials — cement, grain, chemical powders, or mineral aggregates. The low ash content (0.0129%) keeps extrusion dies clean over long production cycles, reducing downtime for screen changes on high-output tape lines.
Big bag fabrication demands consistent melt behavior across wide flat-die extrusion heads. KUNLUN PP S1003 processes smoothly within the 220–240°C melt temperature window, allowing manufacturers to run multiple tape lines at stable output without degrading the polymer structure. Converters producing UN-certified dangerous goods FIBCs and food-grade bulk bags benefit from the resin's clean pellet quality — zero colored particles per kilogram and oversized pellet content below 0.1 g/kg.
Why Source Through BASTONE
Navigating the Chinese petrochemical market requires a partner with established producer relationships. BASTONE Petrochem operates as a listed distributor for China's top three petrochemical manufacturers, including SINOPEC and PetroChina. We secure direct allocations of KUNLUN PP S1003 from PetroChina production facilities, bypassing multi-tier trading networks. FIBC and woven bag manufacturers gain predictable lead times and guaranteed batch-to-batch consistency for their tape extrusion lines.
Trading houses often lack the technical depth to support polymer selection. BASTONE functions as an R&D-oriented chemical group with four independent production sites and a dedicated research center. Our supply chain specialists understand the exact rheological requirements of your extrusion lines. We help production engineers match specific melt flow rates and isotactic indices to their exact machinery constraints.
International logistics demand precise coordination. Zhejiang Bastone Technology Co., Ltd manages all export documentation, customs clearance, and vessel booking. We adapt trade terms and shipping schedules to fit your inventory cycles. Buyers receive accurate packing lists, commercial invoices, and original COAs well before containers arrive at the destination port.
