Barrier Bags and Foil Liners
Multi-layer film or foil bags used inside a drum, box or bulk bag to protect the product.
They give the product the barrier it needs while the outer container only has to carry the load.
Packaging by product
Pharmaceutical Excipients
Excipients are high-purity powders and liquids where documentation, traceability and contamination control outweigh every other factor.
What drives the packaging decision
- Every product-contact layer needs documented compliance from the supplier.
- Contamination control and traceability drive format and liner choices.
- Batch sizes are often small and high-value.
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.
FIBC / Bulk Bag
A woven polypropylene bag with lifting loops, for dry bulk solids and powders.
It is the lightest way to move a tonne of dry product as one handling unit.
The honest trade-off
Barrier liners inside a recoverable outer drum separate purity from logistics: the film carries the compliance burden and the drum only carries the load. Single-use bulk bags suit large volumes with less cleaning validation.
