Fibre Compaction
Hydraulic pressure applied to raw flax during the baling stage determines the final density of the product. This bale density defines the mass of dry fibre occupying a fixed cubic volume, calculated as kilograms per cubic metre. It represents the compression ratio of the raw material before it enters the warehouse facility.
Correct compaction ensures the stability of the stack during prolonged storage in high humidity environments.
Trade Specification
Flax merchants define bale density within the export contract to align with shipping container dimensions and weight limits. The buyer sets these limits to prevent the deformation of the bales during transit across ocean routes. Mills verify the measurements upon arrival to ensure the fibre remains free from internal structural damage caused by excessive pressure.
Low compaction leads to high transport costs due to underutilization of container capacity. High compaction risks the integrity of the natural stalks by increasing the likelihood of fibre breakage.
Process Validation
Quality control teams monitor the hydraulic gauge readings during the pressing phase to verify that every unit matches the declared density profile. Operators adjust the compression force whenever the moisture content of the flax shifts to maintain a consistent output. These recorded values populate the packing list and serve as the standard for settling volume discrepancies between the supplier and the importer.
Stable density prevents the internal shifts that frequently destabilize shipments in transit. Final product consistency depends entirely on the precision of this compression stage.
