Comment on Once again, I am calling on manufacturers to improve their sealing glues

I’m not sure how peanut butter is sealed but usually foil lids are sealed with an induction sealer. Cap it’s tightened down (if not potential for a bad deal) and the foil in the cap is pushed tight to the bottle/jar. The metal heats up, melts the plastic and seals.

This one looks like a pressure seal, which as the name suggests seals by tightening the cap. In my experience from a packing QC standpoint the potential problems with a pressure seal are either the seal not sealing fully because the cap isn’t tightened enough, or the seal getting damaged by the cap being over tightened. This looks like a cheaply made seal wad to me. I dare say the QC department complained about it but management wanted to save a few cents.

The seal looked to be perfectly vacuumed when I opened it, and the lid wasn't a tight one, so I suspect you're right. But someone else in the thread indicated that this may also be a "feature"? I'm not sure if it's a post hoc rationalisation of shit supply purchase choice or a deliberate design decision or a manufacturing error, but it doesn't matter. I hate it all the same.
Also, thanks for providing me with a proper specific name for these things, and the gift of your experience in all things sealed.
