The 81300 series sewing machine is one of the most widely used equipment in the heavy-duty FIBC (Flexible Intermediate Bulk Container) production industry. This model is specifically designed for the side seams and heavy-duty corner seams of FIBCs, featuring a combination of double-needle sewing (502) and chain stitch (401) technology. With its robust frame and powerful motor, it can handle materials up to 19mm thick and is equipped with a filling thread function, making it perfectly suited for FIBC production. We have a long history of manufacturing this sewing machine, and to this day, it remains the most favored choice in the FIBC manufacturing field. For the production of some large bags, this sewing machine is the only indispensable option. The design of this sewing machine fully takes into account the special requirements of FIBC production, not only allowing for thick sewing but also ensuring a firm and aesthetically pleasing result. The combination of double-needle and chain stitch technology makes the side and corner seams of FIBCs more durable and reliable, effectively enhancing the overall quality of the product. Additionally, the inclusion of the filling thread function further strengthens the sewing area, providing a strong guarantee for the safe use of FIBCs. Over the years, we have continuously optimized the performance of this sewing machine to meet the growing demands of the market, which is why it maintains such a high popularity in the FIBC production industry.
