Wouldn't these be positive and negative samples to test against? Like when you do a study of something and you have a control subject or sample that you are 100% will return a specific result so you can use that for reference. That's probably why the positive control is biohazard, it's got covid material in it and the negative is a known clean sample for batch testing.
As far as I know, tests don’t come preloaded negative and positive? Tests are neutral until they are administered. To my knowledge, sealed tests don’t come predetermined.
I believe these are just samples to be used in batch testing. My understanding is that when they do covid tests they do many at once to save resources assuming most will test negative. These are just samples that would be used in the piece of testing equipment along side actual patient samples for calibration or as a control. Inside that package isn't a test itself, probably just a swab that's either clean or has something deposited on it at a lab.
I've worked in healthcare but not in the lab specifically so I'm probably not doing a good job of articulating what I'm trying to say, if you want some more smarty pants terms this link has the info on when / why they use these controls
