4 Loops Big Bags

U-Panel Big Bags

U-Panel style bags are constructed using a three-panel layout. A single primary piece extends all the way along the bag’s length, shaping into a “U” to construct both side walls and the base. The remaining two sides are then stitched onto this central piece. Once loaded with material, U-panel bags retain a neat square profile.

Type: A / B / C / D
Construction: U + 2 sides
SF: Single Trip 5:1 / Multi Trip 6:1
SWL: 500–2,000 kg capacity
Fabric: Tubular circular and flat woven fabric
Lamination / coating: With or without
Dust proofing: With or without
PE liner: With or without
Liner options: Glued / 4 tabs / 8 tabs / winged / freely inserted PE liner
Top: Open top / filling spout / filling skirt
Bottom: Flat closed bottom / discharge spout
Loops: Side seam / cross corner loops

4-Panel Big Bags

4-Panel bags are built from four separate fabric sections stitched together to form a square structure. A key benefit of this four-panel design is its ability to hold a neat, boxy shape once filled.

Type: A / B / C / D
Construction: 4 sides + bottom
SF: Single Trip 5:1 / Multi Trip 6:1
SWL: 500–2,000 kg capacity
Fabric: Tubular circular and flat woven fabric
Lamination / coating: With or without
Dust proofing: With or without
PE liner: With or without
Liner options: Glued / 4 tabs / 8 tabs / winged / freely inserted PE liner
Top: Open top / filling spout / filling skirt
Bottom: Flat closed bottom / discharge spout
Loops: Side seam / cross corner loops

Reinforced Circular Cross Corner Big Bags

Circular-woven bags are produced using seamless fabric woven as a continuous tube on a circular loom, which is then trimmed to the required length. Although square top and bottom panels are stitched onto the structure, these bags retain a distinct cylindrical form once loaded. A primary benefit of the circular design is the reduction in required sewing, as stitching is only needed for the top and bottom panels. This construction is one of the best solutions for leakage prevention.

Type: A / B / C / D
Construction: Circular construction + bottom
SF: Single Trip 5:1 / Multi Trip 6:1
SWL: 500–2,000 kg capacity
Fabric: Reinforced circular woven
Lamination / coating: With or without
Dust proofing: With or without
PE liner: With or without
Liner options: Glued / 4 tabs / 8 tabs / freely inserted PE liner
Top: Open top / filling spout / filling skirt
Bottom: Flat closed bottom / discharge spout
Loops: Cross corner loops

Formstable Baffle / Q-BAG

Baffled bags are engineered to resist bulging and maintain their structural integrity when filled. This is achieved through interior fabric panels featuring strategic openings, which are stitched directly into the bag’s corners. These apertures allow materials to flow freely throughout the interior, ensuring every section is evenly filled.

Type: A / B / C / D
Construction: 4 sides + bottom + 4 internal panels
SF: Single Trip 5:1 / Multi Trip 6:1
SWL: 500–2,000 kg capacity
Fabric: Tubular circular and flat woven fabric
Lamination / coating: With or without
Dust proofing: With or without
PE liner: With or without
Liner options: Glued / 4 tabs / 8 tabs / winged / freely inserted PE liner
Top: Open top / filling spout / filling skirt
Bottom: Flat closed bottom / discharge spout
Loops: Side seam / cross corner loops

UN Big Bags

UN-certified bags are manufactured strictly in compliance with official United Nations guidelines and regulatory standards. Before mass production begins, these specialized FIBCs undergo rigorous testing at an on-site testing facility that is regularly audited by recognized international certification authorities. Our production plant possesses multiple UN certifications covering a diverse range of specialized FIBC designs, with each type engineered to offer distinct features tailored to specific industrial applications.

13H1 FIBCs woven of uncoated PP fabric
13H2 FIBCs woven of coated PP fabric
13H3 FIBCs woven of uncoated PP fabric with PE liner
13H4 FIBCs woven of coated PP fabric with PE liner

Type C Antistatic Big Bags

Type C bags are constructed from standard polypropylene fabric interwoven with conductive threads designed to safely dissipate static electricity, preventing dangerous sparks and brush discharges. To ensure safety, these conductive FIBCs must always be properly grounded to the earth throughout any loading or unloading procedures.

Type D Big Bags

Type D bags are offered in standard materials alongside CROHMIQ® Blue options. Crafted from specialized antistatic and static-dissipative textiles, they are engineered to neutralize hazardous sparks and brush discharges—including propagating brush discharges—entirely without requiring an earth grounding connection.

Ventilated Big Bags

Ventilated bags feature narrow fabric strips engineered to promote continuous air circulation into the interior. Thanks to this enhanced breathability, these bags are ideal for keeping stored goods—such as nuts, potatoes, onions, and firewood or wood chips—properly dry and well-ventilated.

Food Grade Big Bags

Food-grade bags are manufactured within a special environment under strict cleanliness protocols (vacuum cleaning, light-table checks, stainless steel tables, metal detection), ensuring bags meet the rigorous cleanliness requirements necessary for food processing and packaging facilities.
