Chemicals
“Containment is the whole specification.”
In most sectors, a bag that loses a little material is an inefficiency. In chemicals, it can be an exposure event, an environmental violation, a contaminated warehouse floor or a failed safety audit. Fine chemical powders behave more like fluids than solids: they find stitch holes, uncoated weave, loose spout ties and any gap a specification left unexamined. Specifying against that behaviour is the work.
What We Specify For in Chemicals
We engineer bag geometry, polymer compounding, and seam construction against the exact operational risks of this sector.
Eliminating Sift Paths
The most direct answer to powder leakage is to remove the seams. Seamless circular construction eliminates vertical body stitch lines before coatings or liners are even introduced.
Coating & Sift-Proof Cord
Coated PP fabric closes the micro-weave. All critical joining seams are sealed with felt or poly-cord dust-proofing to block sub-micron particles under hydrostatic pressure.
Controlled Discharge
Chemicals are metered into reactors or hoppers rather than dumped. Iris and star closure discharge spouts enable a single operator to start, throttle, and shut off flow without breaking containment.
Batch Quality Documentation
Batch-level rig testing, tensile strength, GSM and UV test reports accompany every export container to support your regulatory and incoming inspection requirements.
Typical Configurations for Chemicals
Indicative starting points, not rigid templates. Final specification follows a detailed engineering review of your cargo behaviour, handling equipment, and transit route.
| Handled Cargo Material | Recommended Construction | Typical Specification Setup |
|---|---|---|
| Fine chemical powders | Circular | Coated, form-fit liner, filling spout, discharge spout with iris, 6:1 SF |
| Granules and flakes | Four Panel or U-Panel | Coated fabric, dust-proof seams, filling spout, discharge spout |
| Polymer resins and pellets | Circular | Coated or uncoated, filling spout, discharge spout, 5:1 SF |
| Dense chemical solids | U-Panel | Coated, heavy GSM, 6:1 SF, discharge spout with star closure |
