I was shocked the other night when I went to open an Aloksak bag that houses an EDC tin and emergency poncho--there was no seal left...nothing...nada! The part that the one side locks into (let's call it the female side) was simply stripped, nothing there, just totally smooth. I don't open this often at all, and the last time I sealed it it was fine. I can't even imagine why this happened. It wasn't subjected to heat, the air was out (ie, it wasn't bulging). Anyone ever see this?

P.S. I was so taken aback that I forgot to see if that side broke off and is attached to the other side.
