The invention provides a food grade laminate for insertion into a food container. The food grade laminate includes a laminate structure having at least one removable edge portion and facing cellulosic webs. Each of the webs have first and second surfaces, a first web edge portion disposed adjacent the removable edge portion, opposing end edge portions and a second edge portion opposite the first edge portion. A substantially oil and grease impermeable food contact layer is laminated on the first surface of the webs. Indicia is printed on the second surface of at least one of the webs. The second surface of the webs along the first edge portion and the opposing end edge portions are substantially adhesively attached to one another to provide the laminate structure. Perforations are provided between adjacent laminate structures on an elongate roll of laminate structures to enable separation between adjacent laminate structures with a separation force ranging from about 6 to about 16 pounds per lineal inch of the perforations.
