mailing refilled 221 oem cartridges

[mrelmo]

for those that may be interested, i mailed a set of refilled cartridges across the country with clean dry results, they were packed in a plastic container as in the photo above, no tape on the vent maze, the only precaution i took was to place each individual cartridge in a small zip lock baggie just encase leakage did occur. also when i mailed them i specified ground transport at the post office, which took 2 extra days but avoided any air pressure changes

That’s good news; you can’t beat the Pony Express mail..

There's no tape that will hold up against the cartridge being unpressurized.

...

When I get a chance, I will seal some "full" cartridges (some air left in the reservoir) and put them in a vacuum chamber to see what happens.

I finally got around to doing the test and the result was:

The aluminum tape covering the air vent hole did not prevent ink leakage out of the air vent hole as predicted.

Living at 7400 feet elevation, I opened a Canon BCI-6 OEM cart in the wrong order (did not pull of the vent sealing heat shrink plastic before I opened the ink outlet orange clip). What a mess!

The ink resvervoir emptied by about 1/3rd out the outlet before pressure equalized! That heat shrink wrap must have been a good seal!

Same precaution when opening a sealed bottle of ink! Do not shake then puncture the seal.

I guess that the foam created by shaking the bottle will expand when the bottle is opened at altitude, much like opening a shaken soda bottle? This would be very messy.
