Innovative and efficient solutions for sewing bulk bags (FIBCs)

LongSew focuses on customized needs, promotes high-end transformation, and expands into emerging markets. Its products are exported to Europe, the United States, South Korea, Brazil, and other countries and regions, and its export business continues to thrive. In recent years, closely following the international market demand for customization and high-end products, the company has gradually explored new development paths. Customized product production based on customer needs has become a significant growth point for the company's export orders, and market demand continues to rise. The company provides customers with a complete set of sewing workshop equipment, including automatic cross-bottom sewing machines, lifting sling sewing machines, double-needle sewing machines, special sewing machines for reinforcement, various single-needle models, container bag cleaning machines, strapping machines, and pneumatic baling presses.

The main function of a bulk bag sewing machine is to cut and sew woven fabric or other materials to form a complete bulk bag. The machine ensures sewing quality and overall bag strength through a series of precise operations.

Its main features include: High efficiency – bulk bag sewing machines are designed with high-speed sewing mechanisms, significantly increasing production efficiency. Automatic feeding system – some high-standard models are equipped with automatic feeding devices, reducing manual intervention and improving production continuity. Multifunctionality – capable of handling fabrics of different thicknesses and materials, meeting diverse product needs. Stability and durability – considering long-term, high-load operation, these machines are usually robustly constructed and easy to maintain. Precise control – modern bulk bag sewing machines use computer control to ensure sewing accuracy and consistency.

Facing increasingly stringent market entry barriers and the trend of diversified customer needs, container bag sewing machines demonstrate the following irreplaceable advantages: Increased capacity: A single machine can produce hundreds of standard container bags per day, increasing efficiency dozens of times compared to manual operation. In particular, fully automatic models can achieve unmanned production from feeding to finished product, making them ideal for large-scale order processing. Controllable quality: A closed-loop tension control system ensures even tension on each thread, and combined with new technologies such as ultrasonic welding, the seam strength reaches or even exceeds that of the base material itself. Strict quality inspection procedures, coupled with online testing equipment, prevent defective products from entering the market. Flexible adaptation: The modular design concept allows for quick replacement of molds and fixtures of different specifications, easily accommodating various bag types such as square, round, and irregular shapes. The software also supports personalized pattern embroidery to meet customers' brand identity needs. Cost reduction and efficiency improvement: Although the initial investment is higher than ordinary equipment, the low failure rate and maintenance costs, coupled with high energy efficiency, significantly reduce the production cost per unit product. In the long run, this is a strategic investment for the company's development. These advantages not only solve the pain points of traditional production methods but also create new profit growth points for the enterprise.

LS7800 sewing machine is developed due to 4-1 sewing machine. Use bigger shuttle hook, with a faster speed max can reach 1000rpm. Compared with old machine, it have obviously advantages. Shuttle hook have features with low speed but more thick material and more thick threads. Even though, still it is widely used in FIBC bag sewing because of low price and stable quality. Option parts for pneumatic foot lift and pneumatic reverse sewing can highly improve working efficiency. Precise feeding mechanism design, Strong top and bottom feeding, can ensure that the upper and lower layers do not move, so that sewing beautiful stitch.Also this machine is very good for using in lifting belt, safety products, Bulk bag, Safety belt, Tent, Suitcases etc.
