Yes these are thin bags but it states it so low density but they are nice and big and perfect for what we use them for. as long as you are not hauling rocks they certainly serve the purpose at a great price.
We have been using this brand of liners for a very long time. They hold up very well when they are stuffed. I must say that it doesn't do much smell control but when you have an office of individuals that eat a variety of foods that would be challening for any liner. Overall this is a very good product.
