A tray is formed from coated paperboard or plastic and is provided with a top peripheral flange onto which a tray lid is sealed. The tray lid includes an inner membrane member which is secured to the tray flange by an adhesive coated into the membrane. Also included in the lid is an outer paperboard member which is adhesively secured to the membrane and tray flange. The outer lid member can be peeled off of the membrane without the membrane releasing from the tray flange. The membrane can then be peeled off of the tray flange to open the tray. A method for forming the sealed trays is also disclosed.
