Extra-strong, heavy-duty trash bags are made with puncture-resistant resins and are three times more puncture-resistant than standard liners. They are ideal for extra-heavy trash applications, such as heavy food, office waste, boxes, cans and construction debris because they are puncture-resistant to sharp objects. Star-bottom seal is designed for a more even distribution of contents. Two-ply, low-density bags come in a convenient coreless roll for easy dispensing anywhere. The 1.5 mil thick bag holds up to 30 gallons. The bag size is 30" x 36". Black plastic resin conceals contents so, even if your janitorial crew collects garbage during regular work hours, you and your guests will not have to look at unsightly garbage.
