Multi wall Bags
Powders and granular materials (e.g. dry chemicals) are often shipped in multi wall plastic bags.

However, in many foreign ports, the stevedores are likely to seize such bags by the ears with inevitable tearing and spillage. This can be avoided by strapping a number of bags together on a pallet.

Barrels
These are used for transporting liquids, e.g. olive oil, and are now usually made of metal.

Containerization
The practice of packing goods within large metal containers for shipment abroad, although an extra cost, has become increasingly popular because of the reduction in water damage, handling damage, and reduction in pilferage. As most ports and ships are equipped to handle containers.

Preventing Dampness

Dampness is considered to be one of the worst hazards to which export shipments are exposed.

The best way of preventing it from causing harm is by sealing the export goods completely from the outside air. This can be accomplished in many different ways and some of them are describe briefly below.

1. Barrier materials
The goods may be wrapped in waterproof paper and sealed with waterproof tape.

2. Rust inhibitors
The goods may be treated with special chemicals so as to provide a protective coating which may later be stripped off or removed with solvent.

3. Desiccants
Non-metallic and other goods that cannot be coated with rust inhibitors can be protected by the use of chemical desiccants, particularly, dehydrating agents that absorb the moisture from the air. These can be used inside airtight containers or with barrier warps. Unlike the rust inhibitors, they leave the product completely free of any foreign coating.

4. Volatile corrosion inhibitors
These prevent rust by giving off a vapor that forms a microscopic coating on the surface to be protected. Colorless, odorless, and tasteless, the VCI may be impregnated into the barrier wrap or it maybe used in crystalline form inside an airtight package.
