Why ink tape come within a vacuum hermetic pack and not a simple pouch?

it stops the ink leak out during shipment.



if there's no air contained by the bag consequently the ink has nowhere to overflow into, and likewise the vacuum also assists contained by keeping the ink in the catridge.
Perhaps so the upper air didn't dry the ink in the tape out before you received it?
or probably because if the cartridge is undermined it wont leak.
nearby are up to 50 micro holes at the point of discharge. in crust the cartridge is not here open for a longer interval even dust particles can block these.
