What Is A PE Baffle Liner Jumbo Container Bag?

With the standardization and upgrading of the bulk material logistics industry, PE baffle-lined jumbo container bags (FIBCs) are widely used in chemical, grain, building materials, and food processing industries due to their advantages such as shape retention, improved loading capacity, and moisture and pollution prevention. These jumbo bags rely on internal compartment baffles to maintain their square shape and evenly distribute material pressure. The sewing process of these compartment baffles directly determines the load-bearing capacity, shaping, and service life of the jumbo bag.

KINGMAX's GK81800-D/GK82800-D direct-drive long-arm jumbo bag sewing machine is a professional heavy-duty sewing machine specifically designed for baffle-lined jumbo bags, FIBCs, and PE-lined compartment bags. It perfectly matches the needs of the entire compartment sewing process, becoming a core piece of equipment for mass production in jumbo bag factories.

The core structure of PE-lined FIBCs (Flexible Intermediate Bulk Containers) consists of PE/PP baffle liner sewn inside the bag. These baffles connect both sides of the bag, preventing outward expansion and bulging when filled with powder or granular materials. This results in more stable stacking, significantly improving container space utilization. Simultaneously, the PE film lining isolates moisture and dust, making it suitable for transporting various fine bulk materials.

However, baffles sewing presents industry pain points: the large volume of FIBCs and the thickness of multi-layered PP woven fabric make it difficult for ordinary short-arm sewing machines to reach inside and sew the internal baffles; sewing thick materials can easily lead to thread misalignment, thread breakage, and uneven stitches; and it's difficult to simultaneously meet requirements such as simultaneous sewing of filling ropes, automatic thread trimming, and continuous high-speed operation.

The GK81800-D series direct-drive long-arm baffle sewing machine was developed to address these challenges, providing a one-stop solution for compartment bag sewing and adapting to two mainstream production solutions: simple single-needle baffles and high-strength double-needle baffles.

Detail specifications

• Extra-large working space for sewing baffle liner of ton bags:

The equipment features a 530×190mm long-stroke arm, allowing for deep insertion into large ton bags to easily sew bag partitions. Combined with a stainless steel tabletop, it ensures smooth handling of thick materials without jamming or wrinkling, perfectly meeting the three-dimensional sewing needs of PE-lined FIBCs.

• Synchronous feeding from top and bottom, preventing shifting when sewing multi-layer thick materials:

Utilizing an alternating top and bottom feeding structure, the equipment is designed for multi-layer thick materials consisting of PP woven fabric and PE lining. The even interlocking and synchronized feeding prevent fabric slippage during the sewing of compartment partitions and straight seams, resulting in neat stitches, effectively reducing defects and ensuring the finished bags are square and stable under pressure.

• Supports double-layer filling rope sewing for enhanced sealing.

Filling ropes can be sewn simultaneously onto the top and bottom of the fabric, sealing needle holes and preventing powder leakage and moisture infiltration. This significantly improves the moisture-proof, dust-proof, and leak-proof performance of the ton bags, meeting the high standards required for food and chemical powder packaging.

• Pneumatic presser foot + hot knife thread trimming for automated and efficient production.

Standard features include a pneumatic automatic presser foot for easier material loading and unloading; a built-in hot knife for automatic thread trimming ensures neat, unfraying threads, eliminating manual thread trimming and increasing production efficiency by over 30%. An independent cooling system allows for long-term, high-speed continuous operation, suitable for mass production in factories.

• Direct-drive servo power + fully automatic lubrication for durability and easy maintenance.

The 1000W servo direct-drive motor offers ample power, low noise, and energy savings, ensuring smooth piercing of thick materials. Fully automatic circulating lubrication throughout the machine reduces head wear and extends lifespan. Stainless steel parts are corrosion-resistant, making cleaning and maintenance easy even in dusty workshops.

Agricultural Sector: Sewing PE-lined FIBCs for grain, seeds, and fertilizer to prevent grain from piling up and bulging, facilitating storage and stacking;

Chemical Industry: Anti-static FIBCs for resin, powder, and chemical additives, with thick-layered, sealed sewing to prevent leakage;

Food Processing: Food-grade FIBCs with inner linings for flour, starch, and sugar, with smooth, even stitching conforming to food packaging standards;

Building Materials and Mining: Heavy-duty FIBCs for cement, mineral powder, and industrial minerals, with double-needle machines providing high-strength FIBC stitching;

General Bulk Logistics: Sewing various standard FIBCs, bulk bags, and Q-BAG FIBCs, also capable of composite sewing of PP outer bags and PE inner linings.

In addition to FIBC sewing, the equipment can also complete the entire process of FIBC body straight sewing, filling and sealing the upper and lower feed inlets with rope, and splicing the inner lining bag. One machine covers the core sewing process of FIBCs, reducing factory equipment investment costs.
