These bags are very thin and cannot hold much weight. If you just throw away Styrofoam then these will probably work. Anything heavier and you will be disappointed.
May have to double bag in some cases depending on contents. Easier than picking up bag contents in the event the bag ruptures. Still cost efective. Black bag is too light.
I don't usually write reviews but had to warn people about these waste of money trash bags. Low density apparently means "no density". They are too small to fit 30 gallon cans they tear if you slightly stretch them to fit. Even when we double bag they split. They are too big to use on our waste baskets - so we have no use for them at all.
