One of our local grocery stores has a different brand of plastic bag, This one has a small adhesive spot between the layers near the opening of the bags. As you pull the bag off, the adhesive pulls the next bag open a little bit. Each bag is slightly open when you pull it off. It works surprisingly well.

I may try to suggest that the other grocery stores adopt this brand but they are big national chains and I doubt they would be interested.

for reference, this bag says PULL-N-PAK® Titan Supreme 28-2024-11-2 www.crownpoly.com

I've seen several different solutions to this problem over the decades, and they all have one thing in common: they quickly get value-engineered out of existence.

There's always a fraction of a cent to be saved by adding slightly less adhesive, using slightly cheaper plastic, replacing the perforating tool less often, etc.; couple iterations in, the solution stops working reliably. There's no back pressure, because it's not like anyone is choosing where they shop by whether the single-use plastic bags are easy to open.
