Bags milled green coffee for shipping in plain jute, jute with a hermetic liner, or vacuum packs, trading cost against protection.
How green coffee is bagged for export shapes how much it degrades in transit. Plain jute is cheap and breathable but has no moisture or oxygen barrier. Jute with a hermetic liner is the specialty standard, in use since around 2006, stopping oxygen and moisture exchange. Vacuum-sealed bags are reserved for premium micro-lots. A liner keeps whatever moisture existed at sealing.
How it worksMilled green coffee ships in plain jute sacks (breathable, with no moisture or oxygen barrier), in jute with a hermetic GrainPro-type liner that blocks oxygen and moisture, or in vacuum-sealed bags reserved for premium micro-lots.

History
GrainPro-type hermetic liners were introduced to specialty coffee around 2006 and are now widely accepted as the way to store and ship specialty green coffee.

What can go wrong
- Plain jute offers no moisture or oxygen barrier and lets coffee oxidize faster.
- A hermetic liner preserves whatever moisture content the coffee had when sealed, so it must be sealed at a proper moisture level.
