Container liners 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.

Containers are discharged by tipping them either by means of a tipping chassis on the delivery vehicle or a tipping platform which may tilt the whole vehicle or the container alone. When a completely sealed discharged system is required, as for sensitive chemicals, a spout is incorporated into the end of the container liner which can be tubular or triangular and which is sealed to a rotary valve. This directs the products into a pneumatic conveying system which carries it up into a silo. If the product is dusty, a ventilation tube can be incorporated into the liner which is connected to the exhaust of the rotary valve and recycles the dust particles back into the liner. Some products are discharged simply by cutting the end of the liner over a grating.

Once discharging is complete, the liner is removed leaving the container clean, dry and ready for another load.

Whatever filling and discharging systems you have in place, we can provide a container liner to suit.
