| Printed Aluminum Sheet Packing |
| Sheet: Sheets are placed in wooden boxes on wooden skids with runners along the length of the sheet. They are wrapped in HDPE with hardboard on top and bottom of the stack. Hoop iron strapping runs along the length of the sheets. Silica gel packets are put in the boxes for moisture protection. |
| Alternatively, they are wrapped in a poly-laminated gunny or polythene, strapped with a hoop iron strap and clip and placed on a wooden pallet. Edge guards are used and the sheets are wrapped with protective thermocol sheets. |
| Coil: Coil is placed on wooden pallets in either eye-to-sky or eye-to-wall condition, wrapped in HDPE fabric and hardboard, and strapped with hoop iron. Silica gel packets are used for moisture protection. |
