The production of high quality PP Woven Bags begins with the extrusion of premium polypropylene resin, which is melted and formed into thin plastic sheets. These sheets are then slit into narrow tapes, which undergo a critical stretching process to align the polymer molecules and drastically increase their tensile strength. Once the tapes are wound onto bobbins, they are loaded into high speed circular weaving looms that interlace the tapes to form a continuous cylindrical fabric tube. This seamless woven construction minimizes weak points, ensuring that the final output can handle significant weight capacities.
After the fabric is woven, it undergoes various finishing processes depending on the specific requirements of the end application. The fabric can be passed through a coating machine to apply a thin layer of poly film, which seals the weave pores and adds water resistance. The material is then precisely cut into desired lengths using heat cutters to prevent the edges from fraying over time. Finally, the bottom of each piece is folded and securely stitched with high strength thread, resulting in finished PP Woven Bags that meet strict industrial standards for durability and load bearing performance.
