Material Protection
Synthetic polymer sheeting secures flax fibre units to maintain structural integrity during maritime transit and storage cycles. This polypropylene bale wrapping serves as the primary barrier against environmental contamination and moisture ingress for raw material exported from Chinese processing facilities. High density extrusion methods produce the tensile strength required to withstand mechanical handling by hydraulic clamps at shipping terminals.
These protective sheets prevent loose fibre loss while ensuring the stack remains compressed to save cargo volume.
Storage Performance
External conditions dictate the gauge and weave density needed for effective containment of the processed plant matter. Moisture barriers within the plastic structure stop humidity fluctuations from altering the natural properties of the flax fibres before spinning begins. Producers apply these sheets immediately after the final mechanical pressing stage to define the shipment unit.
Rigid fastening tapes lock the overlap areas to prevent the wrapping from shifting when operators move the load with forklifts. Proper application ensures the weight recorded at the mill matches the weight received at the destination port.
Quality Assurance
Inspection protocols demand the wrapping remain free from tearing or fraying to prevent foreign material integration within the fibre blend. Quality managers evaluate the elasticity of the synthetic sheet to verify it holds the compressed bale dimensions constant over extended transit durations. If the material splits during the journey the internal fibre quality faces immediate degradation from dust or salt exposure.
The stability of the bale remains dependent on the physical condition of the outer plastic shell throughout the entire logistical chain.
