Greige Fabric Storage Requirements and Preservation Standards
Unfinished greige fabric preservation demands humidity control between 50 and 65 percent relative humidity to prevent size retrogradation and oil oxidation.
High-Density Polyethylene Wrapping
Protective Barrier
Industrial polymer film provides a moisture-proof and tear-resistant shield for finished textile rolls and raw fibre bales during maritime transit. Most global shipping routes require high-density polyethylene wrapping to prevent salt spray and humidity from penetrating the core of the fabric. This material maintains the physical integrity of the goods while they sit in port yards or unconditioned warehouses.
Material Specification
Mechanical properties of the film, such as tensile strength and puncture resistance, are measurably higher than those of standard low-density alternatives. The use of high-density polyethylene wrapping allows for thinner gauges to achieve the same protective effect, reducing the total weight of the packaging. It resists chemical degradation when exposed to floor oils or cleaning agents commonly found in container terminals.
Application Method
Automated heat-shrink systems or orbital stretch wrappers apply the film under tension to create a hermetic seal. When high-density polyethylene wrapping is applied correctly, the layers bond to form a rigid shell that prevents the contents from shifting inside the bale. This stability is necessary for stacking palletized loads in high-bay storage facilities where load shifts can cause structural collapses.
The film thickness is typically measured in microns, with higher grades specified for heavy denim or industrial canvas shipments.
Waste Recovery
Recycling programs at the factory level often collect these films for reprocessing into secondary industrial products. Because high-density polyethylene wrapping is a single-polymer construction, it is easier to sort and wash than multi-layer laminates. Mill managers track the volume of reclaimed plastic to offset the environmental footprint of the packaging department.
