High Density Trash Liners - Natural, 7 - 10 Gallon, .23 Mil. High-density bags are an economical choice for office and restroom waste. Strong yet lightweight liners are best to use where sharp trash is not deposited. Due to their strength, high-density can liners do not need to be as thick as other liners. Bags feature a star seal bottom and are on a coreless roll.
