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…
The stretchy blue ones they make now are awesome. Unfortunately awesome, I buy them sometimes now after years of avoiding them and just reusing whatever bags. The ones that cheese slices come in do seem to have ziplock that is too strong/tight for the bag, I agree. Whether it’s a function of the zipper changing or bags using less plastic, I don’t know.
