These 55-60 gallon, heavy duty, low density garbage bags come in a case of 80. Low density can liners are more stretchable and give more easily than high density bags, because they are made from resins that are highly resistant to puncturing and tearing. These low density garbage bags are also comparatively thicker than high density garbage bags. They should be used with wet and/or heavy trash with sharp, irregular objects from kitchens and bars, because they are stretchable, waterproof, and have a star seal on the bottom. Each of the 60 gallon, 1.9 mil, heavy duty, low density garbage bags measure 38″ x 58″ x 1.9 mil.
