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…
Yeah this is just noticeable because most products weren’t even resealable, they just expected you to seal em yourself with a clip, twist em, put em in a container, etc.
Now they are adding cheap resealable zips to the bag, which is nice in theory but the bag material has to be strong enough to support it.
Actual ziplock baggies themselves are made of thick plastic that can take a bit of abuse.
But cheap paper plastic hybrid materials a chip bag us made of can’t handle that sort of load, so it becomes the fail point.
