Aseptic Bag-in-Drum
A sterile multi-layer bag filled on an aseptic filler and carried inside a drum that acts as the outer shell.
It lets shelf-stable liquid and semi-liquid food move without refrigeration while the product never touches the drum.
Packaging by product
Tomato Paste
Tomato paste moves in huge seasonal volumes, almost always aseptic in drums or bulk formats. Small differences in empty-container economics multiply fast at this scale.
What drives the packaging decision
- Aseptic or hot-fill, high brix, acidic product.
- Seasonal peaks mean large empty-container inventories.
- High volumes make empty-return freight a first-order cost.
Packaging approaches worth considering
Conical / Nesting Steel Drum
A tapered steel drum that nests inside the next one when empty, instead of standing as a full cylinder.
It keeps steel durability and reuse while removing most of the air a straight-wall drum ships when empty.
Carton IBC / Bag-in-Box
A corrugated outer body on a pallet base with a liner bag inside, shipped flat and assembled at the filling line.
It brings intermediate bulk volume without the empty-return burden of a rigid tank.
The honest trade-off
The sterile bag does the product work either way. At seasonal scale, the difference between nesting steel drums and straight-wall drums is measured in truckloads of empty storage and return freight per season.
