These 8 pound "Crystal Ice" plastic ice bags are pre-printed, and the large opening makes packaging ice cubes easy. These ice bags are 1.5 mil thick, measure 12" wide and 18" long, and are made with virgin poly resins, which are FDA and USDA approved for food contact. EVA and Metallocene has been added to these ice bags to increase their strength, for puncture resistance, and for reducing brittleness at ice cold temperatures. Each ice bag is pre-printed with an image of a dog standing on ice with the text "Crystal Ice". There are 500 per case.
