Inside a Bong-Bong Ice Tube Filling Line

Ice tube lines aren't just a filler — the fill line has to hand off cleanly into a cooling or freeze tunnel without the two stages fighting each other's speed. Here's how this multi-lane installation is laid out end to end.

The Line

Multiple tube form-fill-seal lanes run in parallel, feeding an inclined accumulation conveyor that buffers output before the product moves into the cooling or freeze tunnel. Buffering here matters: the filling lanes and the tunnel don't have to run at exactly the same speed if there's a buffer between them, which makes the whole line more forgiving to run.

Engineering Notes

Fill speed and tunnel dwell time have to be planned together — if the tunnel is undersized for the fill rate, product backs up at the infeed.

An accumulation table between filling and freezing buffers output so the two stages don't need to run at the exact same speed.

Tube film has to seal reliably at whatever temperature the product is filled at — cold, viscous product can make some films harder to seal cleanly than others.

Running multiple fill lanes into one shared tunnel means lane synchronization matters — an uneven feed leaves the tunnel belt partially empty and wastes freezer capacity.

Bong-Bong style tubes need a different jaw and sealing profile than round bottle-shaped tube formats — tooling is specified per tube geometry, not shared across formats.
