Ocean Container liner bags are suspended inside the container and can be air or inert gas inflated if required. Loading can be by gravity from overhead hoppers through top fill hatches or through the doors and a false bulkhead using screw or belt conveyors, paddle or belt throwers or a variety of pneumatic systems.
Container liners can be supplied fitted with any combination of top or end fill/discharge spouts correctly aligned with hatches in the container or apertures in false bulkheads or have a completely openable end to allow fork lift truck access. They can have fabric end facings which, when combined with rigid bars act as a false bulkhead and which can have a zipped, wide mouth filling opening.

After loading, spouts are detached from the filler, folded and sealed. Wide mouth openings are closed by means of a zip in the fabric front.
Fork-lift truck "drive-in" liners are extended to allow the opening to be tied closed. Once the liner is closed, the product is completely insulated from the environment and protected from contamination. Unloading is determined by the equipment in use at the product's destination.
