FIBC Bag / Jumbo Bag / Big Bag Double Needles Over edging & Chain stitch Sewing Machine 81300A1H
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 filler cord 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 thread 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.

What kind of FIBC use 81300 series sewing machine?
Extra big bags which need overlock and chain stitch seaming of bag body, 19mm thick body and corner seaming, with 3000-5000D pp threads. Filler cord is needed.
Why choose 81300 series sewing machine?
The 81300 Jumbo Bag Sewing Machine is a heavy-duty safety stitch machine used to sew extra-heavy materials. 81300 series Big bag sewing machine is highly specialized for manufacturing FIBCs, also known as jumbo bags, bulk bags, big bags, or ton bags.
Key parts and applications include:
Why 81300 series sewing Fits These Materials
The 81300 series machines excel at sewing heavy, dense materials such as woven polypropylene (PP), jute, burlap, and geotextiles because they are specifically engineered for demanding industrial applications like FIBC (Jumbo) bags.
They handle these rigid, tough fabrics using several key mechanical features:
Is 81300 required to be used in conjunction with the leak-proof sewing thread (Filler Cord)?
No. The machine is equipped with an upper and lower leak-proof line guiding device. Big bag manufacture can due to bag users’ requirement to decide add filler cord or not. With or without filler cord, this machine all can working well.
What are the causes of frequent thread breakage in sewing?
First, check whether the tension of the thread clamp is too tight; second, inspect whether there are burrs on the threading holes, the needle tips or the needle plates. The heavy-duty machine, operating under high load for a long time, is prone to creating grooves that scrape the thread; finally, confirm whether the machine needles are overheating.
Is this machine self-lubricating? How do I add the lubricant?
Most traditional 81300 machine heads use manual oilers or felt oil storage for lubrication. Due to the large amount of lint produced during the sewing of PP woven bags, it is necessary to clean the lint from the upper and lower feeding teeth and the curved needles before each machine start-up, and to add industrial sewing oil to the designated oiling holes.
