Kirkland Signature 18 Gallon Heavy Duty Trash Bags, 70 Count (4 Pack) - Extra Strong Kitchen & Compactor Garbage Bags for Home, Office & Outdoor Use

Even though we don't have a trash compactor, we buy these bags because they are the BEST and they fit our slightly oversized rectangular garbage container. You can really pack the bag full. We empty other smaller trash containers into this bag when it's full, and really stuff it all down there and they never rip. Additionally, things that would normally poke holes in other bags do not poke holes in these. They are more expensive, but well worth it
