I’ve noticed that every product I’ve bought in the past year with a zip-lock seal is destroyed with common use. I actually think the zip-lock itself has gotten stronger. The bag rips before the seal opens on half the bags now and whenever I try to opens bags I had no issues with before, I find myself stretching/warping the plastic before the seal eventually opens.
It’s pretty frustrating and I am seeing it across many products. Cheese bags, storage bags, snacks etc…
Alternatively, grab a knife or some scissors and skip to step 3.
Oh I know how they’re supposed to open, but yeah I usually just take scissors to them because I have my own jar and a huge box of those O2 packet things someone gave me.
