PACKAGING SYSTEMS FOR INCREASED FOOD PRODUCT SHELF LIFE |
摘要 |
A tray for packaging food, particularly meat, has a peripheral flange with one or more raised ledges to secure a pair of membranes to enclose the tray. A lower membrane may be attached to a first ledge of the flange. An upper membrane may be attached to a second ledge or a recessed lip of the flange without connection to the lower membrane, except through the tray. The two attachment surfaces may be separated by a trough or by being positioned on different levels to facilitate trimming of the upper membrane in a continuous manufacturing process.
