BULK FLOW’s Cubic Bulk Bags with Inner Liners are primarily designed to increase payload when shipping in marine shipping containers by maintaining a cubic shape when filled. The cubic shape eliminates voids between particles inside the container.
BULK-FLOW’s Cubic Bulk Bags with Inner Baffle Liners focus on 2 critical packaging performance aspects:
1. Payload Optimization
Bulk bags with a cubic shape provide a better fit in marine shipping containers, compared to round shape bulk bags that produce space-losing voids in between the bulk bags when loaded into marine shipping containers.
The cubic shape is achieved through the use of inner baffled liners that restrain the sides of the super-sack to prevent an inefficient round form.
The Inner baffled liners are manufactured with an automatic machine to ensure quality consistency and performance.
The payload optimization increases usage of the available space in the marine shipping container and, therefore, reduces freight costs. Freight cost reduction is the single most substantial source of saving.
2. Stable Stackability
The cubic shape of the super-sack is achieved through the use of internal Corner Woven Baffles that connect from one side to the other of the super-sack and restrain the natural tendency of the sides to become round.
Not only does the cubic shape make for a better transporting fit into a marine shipping container, but it also enhances the stability of the bulk bags when stacked. The square footprint provides a more stable base to stack the bulk bags.
Cube bulk bags are low-cost and their benefits compensate, by far, the extra cost of adding internal Corner Woven Baffles.
All of BULK-FLOW’s bulk bags are constructed with a 5:1 SWL – designed to withstand five times the work load. The fabric is UV treated, manufactured to ISO standards and A.I.B. (American Institute of Baking) audited for food grade environments. Quality assurance is monitored for adherence to specifications and quality.
