Ok, I just did a few bags with oxygen absorbers, and the OA bag was air tight, but the bags have not sucked in yet after 2 days. I did see that one bag from a previous test sucked in, but it probably took a few days or a week, which does not sound normal. I thought it should be the next day -24 hours. The bag with the extra 6 OA has also not sucked in even though it was sealed![Mad]
