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 40 to 45 gallons. The bag size is 39" x 46". 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.
