Material: Choose PA+PE nylon composite film. For sea freight, 120–150μm thick barrier film is recommended. It features good puncture resistance, moisture resistance and stable air retention. Avoid low-cost thin single-layer PE bags, which leak quickly in hot and humid conditions.

Structure: Independent one-way check valves ensure the whole bag still works even if one column is damaged. Heavy-duty versions adopt double-layer heat-sealed edges to resist extrusion and cracking.

Types & Inflation: Preformed sleeve bags for small motors and instruments; air column rolls for irregular motorcycle spare parts and multi-SKU inventory. Inflate to 70–80% full. Reserve expansion space to prevent bursting caused by temperature rise at sea.

The film is recyclable. Material test reports are available on request. Custom printing of English warning marks, logos and neutral labels is supported to match shipping marks on outer cartons for neutral export. Note: Air column bags are inner cushioning materials and cannot replace fumigation & quarantine certificates for wooden packaging.

▪ Sea freight / New International Land-Sea Trade Corridor: Thick barrier type, salt spray and moisture resistant ▪ China-Laos Railway & land transport lines: High air tightness type to cope with day-night temperature difference ▪ Overseas warehouse stocking: High air retention type. Rolls allow on-site cutting for flexible use
