Query: Thicker than a popular major brand - Tough!

I have tried these bags as well as a major brand. While these don't have the convenience of built-in handle ties, they are a full 1.5 mil thick, compared to 0.85 mil of the well known brand. These bags are tough. A plastic bag full of recycled paper is heavy, and these bags can hold a full load, without double bagging. I would give it five stars if it had some built in mechanism (probably patented and requiring a license) to either cinch the top or tie it easily. These bags are a bargain, considering you don't have to double bag.
