Circular / Tubular Jumbo Bags

Circular / Tubular Jumbo Bags

Cost-Effective, Seamless Containment for Free-Flowing Commodities

Circular or Tubular Jumbo Bag is an efficient, economical, and durable packing solution that is especially popular to use with powdery and granular substances and agricultural goods that have free flow.

This design is produced on a rotating base and thus has a better structural integrity since all vertical seams that are present with panel bags are eradicated, hence making it a good design in reducing sift leaks and maximizing the production rate.

Engineering for Economy and Efficiency: The Tubular Advantage

The defining feature of the Circular FIBC is its single-piece body construction.

I. Seamless Body Design

Single-Woven Fabric

The whole bag body (except the top and bottom panels) is woven into a continuous polypropylene tube.

Zero Vertical Seams

By removing the four vertical seams of the U-Panel or Four-Panel bags, the Tubular design will remove significant potential weak areas and common routes through which a fine material can escape. This renders it sift-resistant in nature and makes it much simpler to create, and as such, makes it cheaper.

Concentrated Strength

It has concentrated the load-bearing capabilities in the warp (vertical) yarns that constantly run about the bag periphery and offer continuous, high-tensile containment of the bag without the use of stitched connections.

II. Shape and Density

The Tubular bag is rounded in shape and a little cylindrical when filled, as compared to the square shape of panel bags.

Ideal for Automated Filling

The continuous body design is simple and compatible with the high-speed automated filling lines prevalent in the grain and fertilizer industries.

Space Management

Although it is not as perfectly cubic as a Baffle bag, the Tubular design is frequently chosen where the item to be transported is free-flowing and the major consideration is quick, cost-effective, and waterproof wrapping.

Optimized for Handling and Usage

The Circular bag's construction is highly compatible with diverse operational requirements:

I. Lifting Loop Integration

The robust corner seams of the U-Panel are the ideal anchoring point for heavy-duty lifting:

Attached Loops

The lifting loops are sewn onto the woven material, normally in a side seam or straightforward four-loop design, which offers them a sure and effective handling.

Single-Loop and Two-Loop Bags

The Tubular weave is the best to use in Single-Loop and Two-Loop Bags, which is due to its strength. They are prevalent in bulk fertilizer, cement, and specific agricultural commodities, and work is made easier when speed is a crucial factor in the loading.

II. Controlled Discharge and Containment

Discharge / Spout Bags

A Discharge Spout is usually installed on the base, through which the flowing material can be emptied safely and without any mess.

Sift-Proof Confidence

Even though the main benefit is that it has no seams, we do use filler cord technology on the top and bottom base seams (where they are attached) to ensure complete containment.

Comparative Advantage and Key Applications

The Circular FIBC is the workhorse of commodity markets where cost efficiency and containment integrity are paramount.

I. Cost-Effectiveness and Sustainability

Material Efficiency

The cutting process for circular weaving results in less fabric waste compared to multi-panel constructions, providing a more affordable overall bag price.

Single-Trip Focus

Circular bags are frequently certified to a 5:1 Safety Factor (SF), making them the most practical and reliable option for Single-Trip (one-way) transportation of commodity goods.

II. Essential Industries

The Tubular bag's properties make it the first choice for large-volume, dense, or free-flowing non-hazardous materials:

Chemicals & Powders

  • Free-flowing
  • Chemical granules
  • Bulk salt

Food Products & Grains

  • Wheat
  • Rice
  • Pulses
  • sugar (often requiring Food-Grade cleanroom manufacturing)

Agricultural and Fertilizer Manufacturing

  • Grains
  • Seeds
  • Cattle feed
  • Granular NPK Fertilizers
