Extra heavy-duty kraft grocery bags. Tough, strong and sturdy. Made to hold those weighty, awkward items, like bottles, cans and objects where a regular grocery bag just wont do. You can count on the extra strength these bags get from their 50-57 lb. basis weight, up from the 30-40 lb. basis weight of regular bags. You wont have to worry about tearing, ripping or stretching. Designed to stand up stoutly, no falling over or spilling. No need to double bag.
