Bulk Bags / FIBC's

Bulk bags, also known as FIBC’s (Flexible Intermediate Bulk Containers), semi-bulk bags, totes or jumbo bags. Bulk bags can be transported using conventional methods such as shipping containers, road and rail transport and depending on the weight and contents it is possible to double stack with specially designed pallets that allow for forklift access.

Bulk bags have a wide and varied range of transport uses such as: fine powders, food grade products, pharmaceuticals, chemicals, agricultural products, building & construction materials, minerals & powdered metals, petroleum products, plastics, wood and paper products.

Silverback’s bulk bag products are extremely reliable and give peace of mind that our bags will do what they are designed to do. All our bulk bags products are designed, manufactured and tested for compliance with AS/NZS 3668- 1989 and are backed by the Silverback assurance of quality.

Capacity

The size of the bag depends on the quantity and the density o f the material. Manufacturing any size is possible as long as it suits your needs. Common capacity varies from 500kg - 2500kg.

Safety Factor

It is an industry standard requiring the bulk bag to handle five or six times its safe working load (SWL), normally written as a ratio, “5:1 or 6:1 SF”.

Fabric

Woven PP or PE is commonly used. The fabric is UV stabilised so that it does not degrade under direct sunlight. All stitching is double stitched using high tenacity heavy denier PP multifilament yarn. Bulk bags can also be fitted with liners that prevent moisture from reaching the product.

Filling Options

Bulk bags can be filled manually using hand tools (shovels), gravity fed silos or hoppers, conveyors or other machinery such as skid steers or excavators. To assist with hopper or silo filling methods bulk bags can have standard and customised spouts that can be secured to the hopper or silo discharge chute and then sealed when full to protect the cargo. Duffle top bulk bags allow for larger loading opening and can be closed over to seal the cargo from contamination.

Construction

Accepted as the industry standard around the world, the (U-Panel) bulk bag is the most popular shape. Two-piece construction that has two seams sewn along the two opposite sides to create two panels, creating a “U” panel shape. This construction gives the bag a large lifting capacity.

Discharge Options

Emptying bulk bags is achieved via the in-built discharge spout which can be customised to suit the shape of what the cargo is emptied into, manually (shovel) via the duffle top opening or by simply slitting the bottom or lower side of the bag.

Lifting Options

Bags can be lifted using loops made of heavy-duty webbing or belts made of high denier PP multifilament yarn or PP monofilament tapes. These belts are strong and undergo stringent quality checks to ensure no accidents occur while handling these bags. Filled bulk bags are designed for handling using a forklift with standard tyne set up or lifting equipment such as lifting chains or slings.

Classification of Bulk Bags - FIBC's

  • Type - A. No special electrostatic safety features
  • Type - B. Not capable of generating propagating brush discharges. The walls of these bags exhibit a breakdown voltage of 4 kilovolts or less.
  • Type - C. (Conductive) Constructed from electrically conductive fabric, designed to control electrostatic charges by grounding. A standard fabric used contains conductive threads or tape.
  • Type - D. (Anti-Static) Have anti-static or static dissipative properties without the requirement of grounding.
  • UN Type. These bags are designed to handle products that the United Nations considers a hazardous material.
