Silica Gel 500g — Non-woven w/ Hook

Silica Gel 500g hanging hook sachet is specifically engineered for ocean container shipping. The rigid PP hook (load capacity ≥ 2 kg) fits ISO 668 standard container rails, suspending the sachet against the container wall — the optimal moisture absorption position because this is where condensation is highest due to day/night temperature differentials. The client logo is printed directly on the fabric and remains visible during container inspections.
